Organization Consolidation And Presentation Of Financial Statements [Abstract]
Mobile Mini, Inc. - Organization and Description of Business	(1) Mobile Mini, Inc. - Organization and Description of Business Mobile Mini, Inc., a Delaware corporation, is a leading provider of portable storage solutions and tank and pump solutions. In these notes, the terms “Mobile Mini” the “Company,” “we,” “us,” and “our” refer to Mobile Mini, Inc. At September 30, 2018, we had a fleet of storage solutions units operating throughout the United States (the “U.S.”), Canada and the United Kingdom (the “U.K.”), serving a diversified customer base, including construction companies, large and small retailers, medical centers, schools, utilities, distributors, the military, hotels, restaurants, entertainment complexes and households. These customers rent our products for a wide variety of applications, including the storage of construction materials and equipment, retail and manufacturing inventory, documents and records and other goods. We also have a fleet of tank and pump solutions products, concentrated in the U.S. Gulf Coast, including liquid and solid containment units, serving a specialty sector in the industry. Our tank and pump products are rented primarily to chemical, refinery, oil and natural gas drilling, mining and environmental service customers. Basis of Presentation and Consolidation The consolidated financial statements include the accounts of Mobile Mini and our wholly owned subsidiaries. We do not have any subsidiaries in which we do not own 100% of the outstanding stock. All significant intercompany balances and transactions have been eliminated. The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) applicable to interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. In the opinion of management of Mobile Mini, all adjustments (which include normal recurring adjustments) necessary to present fairly the financial position, results of operations, and cash flows for all periods presented have been made. The results of operations for the three and nine months ended September 30, 2018 and 2017, respectively, are not necessarily indicative of the results to be expected for the full year. During the current year, we changed the classification of certain ancillary revenues that were previously reported in rental and other revenues to sales revenues, and the corresponding expenses are now being classified in cost of sales on the accompanying condensed consolidated statements of operations for the three and nine months ended September 30, 2018. As the amounts are immaterial, reclassifications were not made in the corresponding period of the prior year. These condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and accompanying notes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 filed with the Securities and Exchange Commission (“SEC”) on February 2, 2018. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the accompanying condensed consolidated financial statements and the notes to those statements. Actual results could differ from those estimates. Significant estimates affect the calculation of depreciation and amortization, the calculation of the allowance for doubtful accounts, the analysis of goodwill and long-lived assets for potential impairment and certain accrued liabilities.

Accounting Changes And Error Corrections [Abstract]
Impact of Recently Issued Accounting Standards	(2) Impact of Recently Issued Accounting Standards Intangibles – Goodwill and Other – Internal-Use Software . In August 2018, the Financial Accounting Standards Board (“FASB”) issued a standard that provides guidance on accounting for implementation costs incurred in a cloud computing arrangement that is a service contract. The amendments in this update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software, and hosting arrangements that include an internal-use software license. This guidance also requires entities to present the expense related to the capitalized implementation costs in the same line item in the statement of income as the fees associated with the hosting element (service) of the arrangement and classify payments for capitalized implementation costs in the statement of cash flows in the same manner as payments made for fees associated with the hosting element. The entity is also required to present the capitalized implementation costs in the statement of financial position in the same line item that a prepayment for the fees of the associated hosting arrangement would be presented. This standard is effective for annual and interim periods beginning after December 15, 2019. We are currently evaluating the effect the standard will have on our financial statements. Share-Based Compensation – Modifications. In May 2017, the FASB issued a standard which clarifies what constitutes a modification of a share-based payment award. This standard is effective for annual and interim periods beginning after December 15, 2017. We implemented this standard on January 1, 2018 and will apply the guidance to future modifications. Business Combinations . In January 2017, the FASB issued a standard which clarifies the definition of a business and provides a new framework for determining whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This standard is effective for annual and interim periods beginning after December 15, 2017. We implemented this standard on January 1, 2018 and will apply the guidance to future transactions. Intangibles – Goodwill and Other. In January 2017, the FASB issued a standard requiring an entity to no longer perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, impairment will be measured using the difference between the carrying amount and the fair value of the reporting unit. This standard is effective for annual and interim periods beginning after December 15, 2019. Entities may early adopt the guidance. We have not determined an adoption date and do not expect the adoption of this standard to have a material effect on our consolidated financial statements. Leases . In February 2016, the FASB issued a standard on lease accounting requiring a lessee to recognize assets and liabilities on the balance sheet for leases with lease terms greater than 12 months. This standard is effective for annual and interim periods beginning after December 15, 2018. We expect to adopt this standard effective January 1, 2019. A modified retrospective transition approach is required. Entities may choose between applying the new standard as of the date of initial application, or applying the standard to all leases existing as of the earliest comparative period and recasting its comparative period financial statements. We expect to use the effective date as our date of initial application. Consequently, financial information will not be updated and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019. While we are continuing to evaluate all potential impacts of the standard, we do not believe the accounting for our contractual rental revenue will be materially affected by the adoption of this standard. The standard includes optional transition practical expedients intended to simplify its adoption. We intend to elect to use certain of these expedients including, among other things, the ability to retain lease classification determined under legacy GAAP as well as a relief from reviewing expired or existing contracts to determine if they contain leases. We anticipate the lessee accounting for operating leases under the standard will have a material effect on our statement of financial position. Upon adoption, we currently expect to recognize additional operating liabilities totaling between $75 million to $85 million, with corresponding right of use assets. The liabilities will be calculated as the present value of the remaining minimum rental payments for existing operating leases. Revenue from Contracts with Customers . In May 2014, the FASB issued an accounting standard on revenue from contracts with customers. The standard provides a single model for revenue arising from contracts with customers and supersedes previous revenue recognition guidance. The standard requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of goods or services and is effective for annual and interim periods beginning after December 15, 2017. We adopted this guidance with a date of initial application of January 1, 2018. The majority of our revenue, as it relates to contractual rental revenue, is excluded from the scope of this standard, and the accounting for the remaining revenue streams were not affected. We utilized the modified retrospective adoption and there was no impact on our consolidated financial statements, nor was there a cumulative effect of initially applying the standard. For more information regarding our revenue from contracts with customers, see the disclosure in Note 4.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	(3) Fair Value Measurements Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value is a market-based measurement determined by assumptions that market participants would use in pricing an asset or liability. We categorize each of our fair value measurements in one of the following three levels based on the lowest level of input that is significant to the fair value measurement:  Level 1 — Observable inputs such as quoted prices in active markets for identical assets or liabilities; Level 2 — Observable inputs, other than Level 1 inputs in active markets, that are observable either directly or indirectly; and Level 3 — Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions. At September 30, 2018 and December 31, 2017, we did not have any financial instruments required to be recorded at fair value on a recurring basis. The carrying amounts of cash, cash equivalents, receivables, accounts payable and accrued liabilities approximate fair values based on their short-term nature. The fair values of our revolving credit facility and capital leases are estimated using discounted cash flow analyses, based on our current incremental borrowing rates for similar types of borrowing arrangements. Based on the borrowing rates currently available to us for bank loans with similar terms and average maturities, the fair value of our revolving credit facility debt and capital leases, which are measured using Level 2 inputs, at September 30, 2018 and December 31, 2017 approximated their respective book values. The fair value of our $250.0 million aggregate principal amount of 5.875% senior notes due July 1, 2024 (the “Senior Notes” or “2024 Notes”) is based on their latest sales price at the end of each period obtained from a third-party institution and is Level 2 in the fair value hierarchy as there is not an active market for the Senior Notes. The Senior Notes are presented on the balance sheet net of deferred financing costs. The gross carrying value and the fair value of our Senior Notes are as follows: September 30, 2018 December 31, 2017 (In thousands) Carrying value $ 250,000 $ 250,000 Fair value 253,200 262,500

Revenue From Contract With Customer [Abstract]
Revenue from Contracts with Customers	(4) Revenue from Contracts with Customers Revenue Recognition A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Rental contracts with our customers may have multiple performance obligations including the direct rental of fleet to our customers, fleet delivery and pickup. Also included in rental revenues are ancillary fees including late charges and charges for damages. For contracts with multiple performance obligations, we allocate the contract’s transaction price to each performance obligation using the contractually stated price as our best estimate of the standalone selling price of each distinct promise in the contract. Our prices are determined using methods and assumptions developed consistently across similar customers and markets. We enter into contracts with our customers to rent equipment based on a monthly rate for our Storage Solutions fleet and a daily, weekly or monthly rate for our Tank & Pump Solutions fleet. Revenues from renting are recognized ratably over the rental period. The rental continues until cancelled by the customer or the Company. If equipment is returned prior to the end of the contractually obligated period, the excess, if any, between the amount the customer is contractually required to pay, over the cumulative amount of revenue recognized to date, is recognized as incremental revenue upon return. Customers may utilize our equipment delivery and pick-up services in conjunction with the rental of equipment, but it is not required. Revenue pursuant to the delivery or pick up of a rented unit is recognized in rental revenue upon completion of the service. Sales revenue is primarily generated by the sale of new and used units, and to a lesser extent, parts and supplies sold to Tank & Pump Solutions customers. Sales contracts generally have a single performance obligation that is satisfied at the time of delivery. Sales revenue is measured based on the consideration specified in the contract and recognized when the customer takes possession of the unit or other sale items. Our Storage Solutions rental customers are generally billed in advance. Additionally, we may bill our customers in advance for fleet pickup. Tank & Pump Solutions rental customers are typically billed in arrears, a minimum of once per month. Sales transactions are generally billed in advance or upon transfer of the sold items. Payments from customers are generally due upon receipt of the invoice. Certain customers have extended terms for payment, but no terms are greater than one year following the invoice date. Taxes assessed by a governmental authority that are both imposed and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue. As disclosed in Note 2, we adopted new guidance related to revenue from contracts with customers. The adoption did not have a significant impact on our revenue, nor did it result in a cumulative effect adjustment as of January 1, 2018. We have consistently applied our accounting policies to all periods presented in these consolidated financial statements. Contract Costs and Liabilities We incur commission costs to obtain rental contracts and for sales of fleet inventory. We expect the period benefitted by each commission to be less than one year. As a result, we have applied the practical expedient for incremental costs of obtaining a contract and expense commissions as incurred. When customers are billed in advance, we defer recognition of revenue and reflect unearned rental revenue at the end of the period. As of September 30, 2018 and December 31, 2017, we had approximately $39.9 million and $38.3 million, respectively, of unearned rental revenue included in accrued liabilities in the condensed consolidated balance sheets for September 30, 2018 and December 31, 2017. We expect to perform the remaining performance obligations and recognize the unearned rental revenue within the next twelve months. Accordingly, we have applied the practical expedient available, under which we do not disclose the amount of consideration allocable to different performance obligations. Disaggregated Rental Revenue In the following table, rental revenue is disaggregated by the nature of the underlying service provided and for the periods indicated.

Earnings Per Share [Abstract]
Earnings Per Share	(5) Earnings Per Share Basic earnings per share (“EPS”) is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Restricted stock awards are subject to the risk of forfeiture and are not included in the calculation of basic weighted average number of common shares outstanding until vested. Diluted EPS is calculated under the treasury stock method. Potential common shares included restricted common stock and incremental shares of common stock issuable upon the exercise of stock options.

These common stock equivalents were excluded because their inclusion would reduce the net loss per share. In addition, the following table represents the effect of stock options and restricted share awards that were issued or outstanding but excluded in calculating diluted EPS because their effect would have been anti-dilutive for the periods indicated, or the underlying performance criteria had not yet been met: Three Months Ended September 30, Nine Months Ended September 30, 2018 2017 2018 2017 (In thousands) Stock options 691 2,185 724 2,213 Restricted share awards 42 1 27 4 Total 733 2,186 751 2,217

Leases [Abstract]
Rental Fleet	(7) Rental Fleet Rental fleet is capitalized at cost and depreciated over the estimated useful life of the unit using the straight-line method. Rental fleet is depreciated whether or not it is out on rent. Capitalized cost of rental fleet includes the price paid to acquire the unit and freight charges to the location when the unit is first placed in service, and when applicable, the cost of manufacturing or remanufacturing, which includes the cost of customizing units. Ordinary repair and maintenance costs are charged to operations as incurred. We periodically review depreciable lives and residual values against various factors, including the results of our lenders’ independent appraisal of our rental fleet, practices of our competitors in comparable industries and profit margins achieved on sales of depreciated units. See Note 17 for information regarding the impairment charge and loss on divestiture, net related to certain of our fleet during the current period. Appraisals on our rental fleet are required by our lenders on a regular basis. The appraisal typically reports no difference in the value of the unit due to the age or length of time it has been in our fleet. Based in part upon our lender’s third-party appraiser who evaluated our fleet as of September 30, 2017, management estimates that the net orderly liquidation appraisal value as of September 30, 2018 was approximately $1.1 billion. Our net book value for this fleet as of September 30, 2018 was $0.9 billion. Depreciation expense related to our rental fleet for the nine months ended September 30, 2018 and 2017 was $23.9 million and $23.1 million, respectively. At September 30, 2018, all rental fleet units were pledged as collateral under our Amended and Restated ABL Credit Agreement, dated December 14, 2015, with Deutsche Bank AG New York Branch, as administrative agent, and the other lenders party thereto (the “Credit Agreement”).

Property Plant And Equipment [Abstract]
Property, Plant and Equipment	(8) Property, Plant and Equipment Property, plant and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is recorded using the straight-line method over the assets’ estimated useful lives. Our depreciation expense related to property, plant and equipment for the nine months ended September 30, 2018 and 2017 was $21.4 million and $19.0 million, respectively. Normal repairs and maintenance to property, plant and equipment are expensed as incurred. When property or equipment is retired or sold, the net book value of the asset, reduced by any proceeds, is charged to gain or loss on the disposal of property, plant and equipment and is included in rental, selling and general expenses in the condensed consolidated statements of operations. Property, plant and equipment at September 30, 2018 and December 31, 2017 consisted of the following: Residual Value as Percentage of Original Cost Estimated Useful Life in Years September 30, 2018 December 2017 (In thousands) Land $ 2,954 $ 2,970 Vehicles and machinery 0 - 55% 5 - 30 152,782 151,937 Buildings and improvements (1) 0 - 25 3 - 30 26,779 25,079 Furniture, office and computer equipment — 3 - 10 75,966 73,416 Property, plant and equipment 258,481 253,402 Accumulated depreciation (102,860 ) (96,098 ) Property, plant and equipment, net $ 155,621 $ 157,304 (1) Improvements made to leased properties are depreciated over the lesser of the estimated remaining life or the remaining term of the respective lease.

Debt Disclosure [Abstract]
Debt	(10) Debt Lines of Credit On December 14, 2015, we entered into the Credit Agreement with Deutsche Bank AG New York Branch, as administrative agent, and other lenders party thereto. The Credit Agreement provides for a five-year, $1.0 billion first lien senior secured revolving credit facility maturing on or before the earlier of (i) December 14, 2020 and (ii) the date that is 90 days prior to the final maturity date of the Senior Notes, if such Senior Notes remain outstanding on such date. The Credit Agreement also provides for the issuance of irrevocable standby letters of credit by U.S.-based lenders in amounts totaling up to $50.0 million, by U.K.-based lenders in amounts totaling up to $20.0 million, and by Canadian-based lenders in amounts totaling up to $20.0 million. The obligations of Mobile Mini and its subsidiary guarantors under the Credit Agreement are secured by a blanket lien on substantially all of our assets. Amounts borrowed under the Credit Agreement and repaid or prepaid during the term may be reborrowed. Outstanding amounts under the Credit Agreement bear interest at our option at either: (i) the London interbank offered rate (“LIBOR”) plus an applicable margin (“LIBOR Loans”), or (ii) the prime rate plus an applicable margin (“Base Rate Loans”). The applicable margin for each type of loan is based on an availability-based pricing grid and ranges from 1.25% to 1.75% for LIBOR Loans and 0.25% to 0.75% for Base Rate Loans at each measurement date. As of September 30, 2018, the applicable margins are 1.50% for LIBOR Loans and 0.50% for Base Rate Loans. Availability of borrowings under the Credit Agreement is subject to a borrowing base calculation based upon a valuation of the Company’s eligible accounts receivable, eligible fleet (including units held for sale, work-in-process and raw materials) and machinery and equipment, each multiplied by an applicable advance rate or limit. The rental fleet is appraised at least once annually by a third-party appraisal firm and up to 90% of the net orderly liquidation value, as defined in the Credit Agreement, is included in the borrowing base to determine the amount the Company may borrow under the Credit Agreement. At September 30, 2018, we had $610.2 million of borrowings outstanding and $386.4 million of additional borrowing availability under the Credit Agreement. The Credit Agreement provides for U.K. borrowings, which are, at the Company’s option, denominated in either Pounds Sterling or Euros, by its U.K. subsidiary based upon a U.K. borrowing base; Canadian borrowings, which are denominated in Canadian dollars, by its Canadian subsidiary based upon a Canadian borrowing base; and U.S. borrowings, which are denominated in U.S. dollars, by the Company based upon a U.S. borrowing base along with any Canadian assets not included in the Canadian subsidiary. The Credit Agreement also contains customary negative covenants, including covenants that restrict or limit the Company’s ability to, among other things: (i) allow certain liens to attach to the Company’s or its subsidiaries’ assets, (ii) repurchase or pay dividends or make certain other restricted payments on capital stock and certain other securities, or prepay certain indebtedness, (iii) incur additional indebtedness or engage in certain other types of financing transactions, and (iv) make acquisitions or other investments. In addition, we must comply with a minimum fixed charge coverage ratio of 1.00 to 1.00 as of the last day of each quarter, upon the minimum availability amount under the Credit Agreement falling below the greater of (y) $90 million and (z) 10% of the lesser of the then total revolving loan commitment and aggregate borrowing base. As of September 30, 2018, we were in compliance with the minimum borrowing availability threshold set forth in the Credit Agreement and, therefore, are not subject to any financial maintenance covenants. Senior Notes We have outstanding $250.0 million aggregate principal amount of 2024 Notes issued at their face value on May 9, 2016. The 2024 Notes bear interest at a rate of 5.875% per year, have an eight-year term and mature on July 1, 2024. Interest on the 2024 Notes is payable semiannually in arrears on January 1 and July 1. The 2024 Notes are senior unsecured obligations of the Company and are unconditionally guaranteed on a senior unsecured basis by certain of our existing and future domestic subsidiaries. Obligations Under Capital Leases At September 30, 2018 and December 31, 2017, obligations under capital leases for certain real property and transportation related equipment were $61.9 million and $52.8 million, respectively. Certain of the lease agreements provide us with a purchase option at the end of the lease term.

Income Tax Disclosure [Abstract]
Income Taxes	(11) Income Taxes We are subject to taxation in the U.S. federal jurisdiction, as well as various U.S. state and foreign jurisdictions. We have identified our U.S. federal tax return as our “major” tax jurisdiction. As of September 30, 2018, we are no longer subject to examination by U.S. federal tax authorities for years prior to 2014, to examination for any U.S. state taxing authority prior to 2012, or to examination for any foreign jurisdictions prior to 2013. All subsequent periods remain open to examination. Our effective income tax rate decreased to 33.4% for the nine months ended September 30, 2018, compared to 35.1% for the prior-year period. The current period effective tax rate was affected by the reduction of the U.S. federal tax rate from 35% to 21%, which was partially offset by the increase in disallowed deductions for officers’ compensation, both of which are a result of the Tax Cuts and Jobs Act (the “Tax Act”) enacted on December 22, 2017. Additionally, income tax benefits were recognized due to state tax rate changes enacted in the third quarter and for adjustments made to provisional amounts related to repatriation of foreign earnings, which had the effect of increasing the effective tax rate due to the $33.5 million pre-tax loss recognized during the nine month period. In December 2017, we recorded $3.1 million of provisional tax expense related to the repatriation of foreign earnings attributable to the impact of the Tax Act. We have not yet finalized these calculations, however an adjustment to the provisional amount has been made in the current nine-month period of a $2.9 million benefit, reducing this provisional amount to $0.2 million. The adjustment was primarily due to additional analysis of historical ownership and financial information, including depreciation estimates, as well as state responses to tax reform enacted in the period. We continue to obtain and analyze information related to the depreciation estimates impacting the deemed repatriation of foreign earnings and will finalize the provisional amounts within one year from the date of enactment. Our policy for recording interest and penalties associated with audits is to record such items as a component of income before taxes. Penalties and associated interest costs, if any, are recorded in rental, selling and general expenses in our condensed consolidated statements of operations. As of September 30, 2018, we no longer have unrecognized tax benefits. The reduction to our unrecognized tax benefits in the period had no effect on our effective tax rate. A reconciliation of the beginning and ending balance of our unrecognized tax position is as follows (in thousands): Gross Position Tax Effect Balance as of January 1, 2018 $ 14,140 $ 3,521 Additions based on tax positions related to the current year — — Additions for tax positions of prior years — — Reduction for settlements (14,140 ) (3,521 ) Balance as of September 30, 2018 $ — $ —

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Share-Based Compensation	(12) Share-Based Compensation We have historically awarded stock options and restricted stock awards for employees and non-employee directors as a means of attracting and retaining quality personnel and to align employee performance with stockholder value. Share-based compensation plans are approved by our stockholders and administered by the stock compensation committee of the Company’s Board of Directors (the “Board”). The current plan allows for a variety of equity programs designed to provide flexibility in implementing equity and cash awards, including incentive stock options, nonqualified stock options, restricted stock awards, restricted stock units, stock appreciation rights, performance stock, performance units and other stock-based awards. Participants may be granted any one of the equity awards or any combination. We do not award stock options with an exercise price below the market price of the underlying securities on the date of grant. As of September 30, 2018, 1.6 million shares are available for future grants, assuming performance-based awards vest at their target amount. Generally, stock options have contractual terms of ten years. Expense related to performance-based awards is recognized based upon anticipated attainment. The following table summarizes the Company’s share-based compensation for the three and nine months ended September 30: Three Months Ended September 30, Nine Months Ended September 30, 2018 2017 2018 2017 (In thousands) Share-based compensation expense included in: Rental, selling and general expenses $ 2,230 $ 2,071 $ 7,503 $ 5,890 Restructuring expenses — — 363 — Total share-based compensation $ 2,230 $ 2,071 $ 7,866 $ 5,890 During the nine months ended September 30, 2017, the final vesting dates were accelerated for certain share-based compensation awards to an executive departing the Company. The vesting dates were adjusted to correspond to the executive’s departure date, resulting in expense of $0.2 million in the quarter ended September 30, 2017 and a total of $1.2 million in the nine month period ended September 30, 2017. The expense related to the acceleration is included in rental, selling and general expenses in the condensed consolidated statements of operations for the three and nine months ended September 30, 2017. As of September 30, 2018, total unrecognized compensation cost related to stock option awards assuming achievement at target was approximately $0.8 million and the related weighted-average period over which it is expected to be recognized is approximately 0.7 years. As of September 30, 2018, the unrecognized compensation cost related to restricted stock awards assuming achievement at target was approximately $8.2 million, which is expected to be recognized over a weighted-average period of approximately 1.9 years. Stock Options. The fair value of each stock option award is estimated on the date of the grant using the Black-Scholes-Merton option pricing model which requires the input of assumptions. We estimate the risk-free interest rate based on the U.S. Treasury security rate in effect at the time of the grant. The expected life of the options, volatility and dividend rates are estimated based on our historical data. No new stock options were issued in 2018. The following are the key assumptions used for the nine-month period ended September 30, 2017: Risk-free interest rate 1.7% - 1.9% Expected life of the options (years) 5 Expected stock price volatility 33.4% - 35.4% Expected dividend rate 2.8% - 3.1% The following table summarizes stock option activity for the nine months ended September 30, 2018: Number of Shares Weighted Average Exercise Price (In thousands) Options outstanding, beginning of period 3,169 $ 32.49 Additional options granted based upon achievement of specified performance criteria 81 32.42 Canceled/Expired (174 ) 27.75 Exercised (118 ) 30.86 Options outstanding, end of period 2,958 32.70 The beginning balance of options outstanding in the table above includes approximately 0.7 million unvested performance-based stock options granted in 2017 and 2016, for which the targets were set at the time of the grant. For options granted in both 2017 and 2016, vesting conditions were related to the Company’s return on capital employed. Certain options granted in 2017 vested contingent upon 2017 performance targets. Actual performance exceeded targets for these shares. As a result, in the first quarter of 2018, in addition to the target options included in the beginning balance, additional options were vested. Certain options granted in 2016 also vested contingent upon 2017 performance targets. Actual performance did not achieve the minimum vesting requirements for these shares. As a result, shares totaling 0.1 million are included in the canceled/expired shares in the above table. Included in the options outstanding at the end of the period are approximately 0.5 million of unvested performance-based stock options granted in 2017 and 2016 for which the performance criteria relates to fiscal years 2018 and 2019. These stock options are included in the table at the target amount; however, the terms of these awards provide that the number of options that ultimately vest may vary between 50% and 200% of the target award, or may be zero. A summary of stock options outstanding as of September 30, 2018 is as follows: Number of Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Terms Aggregate Intrinsic Value (I n (In years) (In thousands) Outstanding 2,958 $ 32.70 5.29 $ 33,534 Exercisable 2,593 33.01 4.90 28,662 The aggregate intrinsic value of options exercised during the nine months ended September 30, 2018 was approximately $1.4 million. Restricted Stock Awards. The fair value of restricted stock awards is estimated as the closing price of our common stock on the date of grant. A summary of restricted stock award activity is as follows: Shares Weighted Average Grant Date Fair Value (In thousands) Restricted stock awards at beginning of period 234 $ 31.42 Awarded 225 38.45 Released (106 ) 34.30 Forfeited (13 ) 36.67 Restricted stock awards at end of period 340 34.99 Included in the restricted stock awarded in 2018 are 0.1 million shares that vest based upon the achievement of specified performance criteria related to fiscal years 2018, 2019 and 2020. Such awards have been granted assuming a target number of shares. However, the terms of these awards provide that the number of shares that ultimately vest may vary between 50% and 200% of the target award, or may be zero. The table presents the awards at their target amount. The restricted stock awards that vested during the nine months ended September 30, 2018 had an aggregate grant date fair value of $3.6 million and an aggregate vesting date fair value of $4.3 million.

Restructuring	(13) Restructuring We have undergone restructuring actions to align our business operations. Of the $1.3 million of restructuring expenses recognized in the nine months ended September 30, 2018, $0.9 million related to the restructuring of our corporate service center, including the severance of an executive. The remainder primarily related to projects initiated in prior years that were not accruable during such periods. Of the $2.1 million of restructuring expense recognized in the nine months ended September 30, 2017, approximately $0.8 million of expenses largely related to the abandonment of yards, or portions of yard, as well as related fleet and other costs due to the divestiture of our wood mobile office business. Additionally, $1.3 million related to activities associated with the continued integration of Evergreen Tank Solutions (“ETS”) into the existing Mobile Mini infrastructure.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	(14) Commitments and Contingencies We are a party to various claims and litigation in the normal course of business. Our current estimated range of liability related to various claims and pending litigation is based on claims for which our management can determine that it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. Because of the uncertainties related to both the probability of incurred and possible range of loss on pending claims and litigation, management must use considerable judgment in making reasonable determination of the liability that could result from an unfavorable outcome. As additional information becomes available, we will assess the potential liability related to our pending litigation and revise our estimates. Such revisions in our estimates of the potential liability could materially impact our results of operation. We do not anticipate the resolution of such matters known at this time will have a material adverse effect on our business or consolidated financial position.

During the nine months ended September 30, 2018, we did not purchase shares of our common stock under the authorized share repurchase program. Approximately $70.8 million is available for repurchase as of September 30, 2018. We withheld approximately 17,000 shares of stock from employees, for an approximate value of $0.7 million, upon vesting of share awards to satisfy minimum tax withholding obligations during the nine months ended September 30, 2018. These shares were not acquired pursuant to the share repurchase program.

Segment Reporting [Abstract]
Segment Reporting	(16) Segment Reporting Our operations are comprised of three reportable segments: North American Storage Solutions, U.K. Storage Solutions and Tank & Pump Solutions. Discrete financial data on each of our products is not available and it would be impractical to collect and maintain financial data in such a manner. The results for each segment are reviewed discretely by our chief operating decision maker. We operate in the U.S., the U.K. and Canada. All of our locations operate in their local currency. Although we are exposed to foreign exchange rate fluctuation in foreign markets where we rent and sell our products, we do not believe such exposure will have a significant impact on our results of operations. Revenues recognized by our U.S. locations were $125.8 million and $113.1 million for the three months ended September 30, 2018 and 2017, respectively, and were $362.0 million and $320.5 million for the nine months ended September 30, 2018 and 2017, respectively. The following tables set forth certain information regarding each of the Company’s segments for the three-month periods indicated: For the Three Months Ended September 30, 2018 Storage Solutions North America United Kingdom Total Tank & Pump Solutions Consolidated (In thousands) Revenues: Rental $ 92,241 $ 20,398 $ 112,639 $ 28,285 $ 140,924 Sales 5,103 2,593 7,696 1,020 8,716 Other — 40 40 27 67 Total revenues 97,344 23,031 120,375 29,332 149,707 Costs and expenses: Rental, selling and general expenses 57,662 13,459 71,121 19,643 90,764 Cost of sales 3,178 2,048 5,226 544 5,770 Asset impairment charge and loss on divestiture, net 87,658 8,434 96,092 2,186 98,278 Depreciation and amortization 7,892 1,866 9,758 6,433 16,191 Total costs and expenses 156,390 25,807 182,197 28,806 211,003 (Loss) income from operations $ (59,046 ) $ (2,776 ) $ (61,822 ) $ 526 $ (61,296 ) Interest expense, net of interest income $ 7,589 $ 200 $ 7,789 $ 2,698 $ 10,487 Income tax benefit (16,699 ) (454 ) (17,153 ) (2,441 ) (19,594 ) Capital expenditures for additions to rental fleet, excluding acquisitions 18,290 1,243 19,533 7,611 27,144 For the Three Months Ended September 30, 2017 Storage Solutions North America United Kingdom Total Tank & Pump Solutions Consolidated (In thousands) Revenues: Rental $ 84,249 $ 20,239 $ 104,488 $ 23,207 $ 127,695 Sales 4,503 2,240 6,743 1,695 8,438 Other 274 127 401 102 503 Total revenues 89,026 22,606 111,632 25,004 136,636 Costs and expenses: Rental, selling and general expenses 57,327 12,868 70,195 17,550 87,745 Cost of sales 2,657 1,820 4,477 1,042 5,519 Restructuring expenses 500 — 500 125 625 Depreciation and amortization 8,052 1,784 9,836 6,099 15,935 Total costs and expenses 68,536 16,472 85,008 24,816 109,824 Income from operations $ 20,490 $ 6,134 $ 26,624 $ 188 $ 26,812 Interest expense, net of interest income $ 6,370 $ 125 $ 6,495 $ 2,704 $ 9,199 Income tax provision (benefit) 6,280 981 7,261 (878 ) 6,383 Capital expenditures for additions to rental fleet, excluding acquisitions 16,629 4,509 21,138 1,780 22,918 The following tables set forth certain information regarding each of the Company’s segments for the nine-month periods indicated: For the Nine Months Ended September 30, 2018 Storage Solutions North America United Kingdom Total Tank & Pump Solutions Consolidated (In thousands) Revenues: Rental $ 264,227 $ 61,066 $ 325,293 $ 80,856 $ 406,149 Sales 15,211 6,574 21,785 3,915 25,700 Other 238 161 399 112 511 Total revenues 279,676 67,801 347,477 84,883 432,360 Costs and expenses: Rental, selling and general expenses 171,182 41,066 212,248 56,785 269,033 Cost of sales 9,401 5,294 14,695 2,230 16,925 Restructuring expenses 1,306 — 1,306 — 1,306 Asset impairment charge and loss on divestiture, net 87,658 8,434 96,092 2,186 98,278 Depreciation and amortization 25,349 6,049 31,398 18,808 50,206 Total costs and expenses 294,896 60,843 355,739 80,009 435,748 (Loss) income from operations $ (15,220 ) $ 6,958 $ (8,262 ) $ 4,874 $ (3,388 ) Interest expense, net of interest income $ 21,443 $ 631 $ 22,074 $ 8,099 $ 30,173 Income tax (benefit) provision (8,876 ) 1,269 (7,607 ) (3,575 ) (11,182 ) Capital expenditures for additions to rental fleet, excluding acquisitions 39,400 5,805 45,205 20,415 65,620 For the Nine Months Ended September 30, 2017 Storage Solutions North America United Kingdom Total Tank & Pump Solutions Consolidated (In thousands) Revenues: Rental $ 236,326 $ 57,454 $ 293,780 $ 66,508 $ 360,288 Sales 14,407 6,356 20,763 4,054 24,817 Other 1,109 309 1,418 330 1,748 Total revenues 251,842 64,119 315,961 70,892 386,853 Costs and expenses: Rental, selling and general expenses 161,122 37,429 198,551 50,403 248,954 Cost of sales 8,727 5,081 13,808 2,231 16,039 Restructuring expenses 1,933 — 1,933 129 2,062 Depreciation and amortization 23,316 5,180 28,496 18,445 46,941 Total costs and expenses 195,098 47,690 242,788 71,208 313,996 Income (loss) from operations $ 56,744 $ 16,429 $ 73,173 $ (316 ) $ 72,857 Interest expense, net of interest income $ 17,897 $ 377 $ 18,274 $ 8,118 $ 26,392 Income tax provision (benefit) 16,593 2,629 19,222 (2,943 ) 16,279 Capital expenditures for additions to rental fleet, excluding acquisitions 31,833 9,037 40,870 5,075 45,945 Assets related to the Company’s reportable segments include the following: Storage Solutions North America United Kingdom Total Tank & Pump Solutions Consolidated (In thousands) As of September 30, 2018: Goodwill $ 468,656 $ 56,896 $ 525,552 $ 181,216 $ 706,768 Intangibles, net 974 415 1,389 55,775 57,164 Rental fleet, net 652,677 144,810 797,487 128,469 925,956 As of December 31, 2017: Goodwill $ 468,785 $ 58,906 $ 527,691 $ 181,216 $ 708,907 Intangibles, net 1,314 642 1,956 60,068 62,024 Rental fleet, net 714,154 156,413 870,567 118,587 989,154 Included in the table above are assets in the U.S. of $1.5 billion as of both September 30, 2018 and December 31, 2017.

Assets Held For Sale Not Part Of Disposal Group [Abstract]
Held for Sale Assets	(17) Held for Sale Assets Consistent with our strategy to focus on high returning assets, during the second quarter of 2018 we initiated an organization-wide project to assess the economic and operational status of our fleet and other assets as well as an in depth analysis of our fleet management process to identify inefficiencies. The task encompassed an intensive review of underperforming assets throughout North America and the United Kingdom using our recently implemented enterprise resource planning system and sophisticated work order system that allows specific identification of the status of each unit and facilitates deeper analysis of repair and maintenance costs. The result of this review was the identification of specific assets over which a further determination as to the economics of continued retention and repair could be made. In July 2018 management presented a proposed plan of sale for certain identified assets to the Board of Directors, and on July 24, 2018 the Board of Directors made the strategic decision to approve the plan and authorized management to begin actively marketing the assets for sale. As a result, we placed these assets as held for sale and recognized a $98.3 million loss on divestiture, which consisted of a non-cash loss of $106.2 million, net of estimated proceeds. The majority of the assets will be sold as scrap metal. Proceeds were primarily estimated by obtaining quotes from regional scrapping companies based on the net tonnage of the fleet to be scrapped. The assets represent a subset of larger asset groups held by the Company and we expect to complete the sale of the assets by December 31, 2018. In addition to rental fleet, we also identified and placed for sale, property, plant and equipment and inventory that were not being used efficiently. In conjunction with this project, we evaluated the assigned depreciable lives and salvage values of our fleet. We believe that the assigned lives and salvage values discussed in Note 7 continue to be appropriate for our fleet. As a result of the reduction to our fleet and property, plant and equipment we expect depreciation expense to decrease approximately $0.9 million per quarter. Related to this activity, the Company expects to recognize exit costs as positions are eliminated and yards, or portions of yards are exited. The estimated loss as adjusted is set forth below: Net Book Value Units (In thousands) North America Storage Solutions Fleet: Steel storage containers $ 56,986 19,718 Steel ground level offices 29,969 3,459 Other 346 275 United Kingdom Storage Solutions Fleet 8,027 1,482 Tank & Pump Solutions Fleet 1,223 472 Other 9,644 n/a Total 106,195 25,406 Estimated net proceeds (8,008 ) Initial estimated net loss on impairment and divestiture 98,187 Net proceeds received (above) below impaired value 91 Estimated net loss on impairment and divestiture $ 98,278 The table below sets forth the activity related to the assets held for sale subsequent to the initial impairment: North America Storage Solutions Fleet United Kingdom Storage Solutions Fleet Tank & Pump Solutions Fleet Other Assets Total (In thousands) Value of assets upon initial impairment $ 5,876 $ 333 $ 161 $ 1,638 $ 8,008 Impaired value of sold assets (2,776 ) (34 ) (65 ) (504 ) (3,379 ) Effect of exchange rates (1 ) (1 ) — 1 (1 ) Other (57 ) 8 — 57 8 Balance of held for sale assets $ 3,042 $ 306 $ 96 $ 1,192 $ 4,636 Held for sale assets are included in other assets in the accompanying condensed consolidated balance sheet.

Mobile Mini, Inc. - Organization and Description of Business (Policies)	9 Months Ended

Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The consolidated financial statements include the accounts of Mobile Mini and our wholly owned subsidiaries. We do not have any subsidiaries in which we do not own 100% of the outstanding stock. All significant intercompany balances and transactions have been eliminated. The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) applicable to interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. In the opinion of management of Mobile Mini, all adjustments (which include normal recurring adjustments) necessary to present fairly the financial position, results of operations, and cash flows for all periods presented have been made. The results of operations for the three and nine months ended September 30, 2018 and 2017, respectively, are not necessarily indicative of the results to be expected for the full year. During the current year, we changed the classification of certain ancillary revenues that were previously reported in rental and other revenues to sales revenues, and the corresponding expenses are now being classified in cost of sales on the accompanying condensed consolidated statements of operations for the three and nine months ended September 30, 2018. As the amounts are immaterial, reclassifications were not made in the corresponding period of the prior year. These condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and accompanying notes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 filed with the Securities and Exchange Commission (“SEC”) on February 2, 2018.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the accompanying condensed consolidated financial statements and the notes to those statements. Actual results could differ from those estimates. Significant estimates affect the calculation of depreciation and amortization, the calculation of the allowance for doubtful accounts, the analysis of goodwill and long-lived assets for potential impairment and certain accrued liabilities.
Fair Value Measurements	Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value is a market-based measurement determined by assumptions that market participants would use in pricing an asset or liability. We categorize each of our fair value measurements in one of the following three levels based on the lowest level of input that is significant to the fair value measurement:  Level 1 — Observable inputs such as quoted prices in active markets for identical assets or liabilities; Level 2 — Observable inputs, other than Level 1 inputs in active markets, that are observable either directly or indirectly; and Level 3 — Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions.
Earnings Per Share	Basic earnings per share (“EPS”) is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Restricted stock awards are subject to the risk of forfeiture and are not included in the calculation of basic weighted average number of common shares outstanding until vested. Diluted EPS is calculated under the treasury stock method. Potential common shares included restricted common stock and incremental shares of common stock issuable upon the exercise of stock options.
Inventories	Inventories are valued at the lower of cost (principally on a standard cost basis which approximates the first-in, first-out method) or net realizable value. Raw materials and supplies principally consist of raw steel, glass, paint, vinyl and other assembly components used in manufacturing and remanufacturing processes and, to a lesser extent, parts used for internal maintenance and ancillary items held for sale in our Tank & Pump Solutions segment. Work-in-process primarily represents partially assembled units. Finished units primarily represent purchased or assembled containers held in inventory until the container is either sold as is, remanufactured and sold, or remanufactured and deployed as rental fleet.
Property, Plant and Equipment	Property, plant and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is recorded using the straight-line method over the assets’ estimated useful lives. Our depreciation expense related to property, plant and equipment for the nine months ended September 30, 2018 and 2017 was $21.4 million and $19.0 million, respectively. Normal repairs and maintenance to property, plant and equipment are expensed as incurred. When property or equipment is retired or sold, the net book value of the asset, reduced by any proceeds, is charged to gain or loss on the disposal of property, plant and equipment and is included in rental, selling and general expenses in the condensed consolidated statements of operations.
Segment Reporting, Policy	Our operations are comprised of three reportable segments: North American Storage Solutions, U.K. Storage Solutions and Tank & Pump Solutions. Discrete financial data on each of our products is not available and it would be impractical to collect and maintain financial data in such a manner. The results for each segment are reviewed discretely by our chief operating decision maker. We operate in the U.S., the U.K. and Canada. All of our locations operate in their local currency. Although we are exposed to foreign exchange rate fluctuation in foreign markets where we rent and sell our products, we do not believe such exposure will have a significant impact on our results of operations. Revenues recognized by our U.S. locations were $125.8 million and $113.1 million for the three months ended September 30, 2018 and 2017, respectively, and were $362.0 million and $320.5 million for the nine months ended September 30, 2018 and 2017, respectively.
Impact of Recently Issued Accounting Standards	Impact of Recently Issued Accounting Standards Intangibles – Goodwill and Other – Internal-Use Software . In August 2018, the Financial Accounting Standards Board (“FASB”) issued a standard that provides guidance on accounting for implementation costs incurred in a cloud computing arrangement that is a service contract. The amendments in this update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software, and hosting arrangements that include an internal-use software license. This guidance also requires entities to present the expense related to the capitalized implementation costs in the same line item in the statement of income as the fees associated with the hosting element (service) of the arrangement and classify payments for capitalized implementation costs in the statement of cash flows in the same manner as payments made for fees associated with the hosting element. The entity is also required to present the capitalized implementation costs in the statement of financial position in the same line item that a prepayment for the fees of the associated hosting arrangement would be presented. This standard is effective for annual and interim periods beginning after December 15, 2019. We are currently evaluating the effect the standard will have on our financial statements. Share-Based Compensation – Modifications. In May 2017, the FASB issued a standard which clarifies what constitutes a modification of a share-based payment award. This standard is effective for annual and interim periods beginning after December 15, 2017. We implemented this standard on January 1, 2018 and will apply the guidance to future modifications. Business Combinations . In January 2017, the FASB issued a standard which clarifies the definition of a business and provides a new framework for determining whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This standard is effective for annual and interim periods beginning after December 15, 2017. We implemented this standard on January 1, 2018 and will apply the guidance to future transactions. Intangibles – Goodwill and Other. In January 2017, the FASB issued a standard requiring an entity to no longer perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, impairment will be measured using the difference between the carrying amount and the fair value of the reporting unit. This standard is effective for annual and interim periods beginning after December 15, 2019. Entities may early adopt the guidance. We have not determined an adoption date and do not expect the adoption of this standard to have a material effect on our consolidated financial statements. Leases . In February 2016, the FASB issued a standard on lease accounting requiring a lessee to recognize assets and liabilities on the balance sheet for leases with lease terms greater than 12 months. This standard is effective for annual and interim periods beginning after December 15, 2018. We expect to adopt this standard effective January 1, 2019. A modified retrospective transition approach is required. Entities may choose between applying the new standard as of the date of initial application, or applying the standard to all leases existing as of the earliest comparative period and recasting its comparative period financial statements. We expect to use the effective date as our date of initial application. Consequently, financial information will not be updated and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019. While we are continuing to evaluate all potential impacts of the standard, we do not believe the accounting for our contractual rental revenue will be materially affected by the adoption of this standard. The standard includes optional transition practical expedients intended to simplify its adoption. We intend to elect to use certain of these expedients including, among other things, the ability to retain lease classification determined under legacy GAAP as well as a relief from reviewing expired or existing contracts to determine if they contain leases. We anticipate the lessee accounting for operating leases under the standard will have a material effect on our statement of financial position. Upon adoption, we currently expect to recognize additional operating liabilities totaling between $75 million to $85 million, with corresponding right of use assets. The liabilities will be calculated as the present value of the remaining minimum rental payments for existing operating leases. Revenue from Contracts with Customers . In May 2014, the FASB issued an accounting standard on revenue from contracts with customers. The standard provides a single model for revenue arising from contracts with customers and supersedes previous revenue recognition guidance. The standard requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of goods or services and is effective for annual and interim periods beginning after December 15, 2017. We adopted this guidance with a date of initial application of January 1, 2018. The majority of our revenue, as it relates to contractual rental revenue, is excluded from the scope of this standard, and the accounting for the remaining revenue streams were not affected. We utilized the modified retrospective adoption and there was no impact on our consolidated financial statements, nor was there a cumulative effect of initially applying the standard. For more information regarding our revenue from contracts with customers, see the disclosure in Note 4.
Rental Fleet, Policy	Rental fleet is capitalized at cost and depreciated over the estimated useful life of the unit using the straight-line method. Rental fleet is depreciated whether or not it is out on rent. Capitalized cost of rental fleet includes the price paid to acquire the unit and freight charges to the location when the unit is first placed in service, and when applicable, the cost of manufacturing or remanufacturing, which includes the cost of customizing units. Ordinary repair and maintenance costs are charged to operations as incurred. We periodically review depreciable lives and residual values against various factors, including the results of our lenders’ independent appraisal of our rental fleet, practices of our competitors in comparable industries and profit margins achieved on sales of depreciated units.
