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 March 31, 2019, 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 months ended March 31, 2019 and 2018, respectively, are not necessarily indicative of the results to be expected for the full 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, 2018 filed with the Securities and Exchange Commission (“SEC”) on February 5, 2019. 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 (the “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. 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 adopted this standard effective January 1, 2019, utilizing a modified retrospective transition approach. We chose to use the effective date as our date of initial application. Consequently, financial information was not updated and the disclosures required under the new standard were not provided for dates and periods before January 1, 2019. The standard includes optional transition practical expedients intended to simplify its adoption. We elected to adopt the package of practical expedients, which allowed us to retain the historical lease classification determined under legacy GAAP as well as a relief from reviewing expired or existing contracts to determine if they contain leases. Upon adoption, we recognized operating lease liabilities totaling approximately $91 million, with corresponding right of use assets. The liabilities were calculated as the present value of the remaining minimum rental payments for existing operating leases. When we enter contractual arrangements as lessor, we expect the period of each rental to be less than one year. As such, the accounting for contracts in which we are the lessor is not affected. This standard did not materially impact our consolidated net earnings and had no impact on cash flows. See Note 11 for additional information.

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 March 31, 2019 and December 31, 2018, 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 finance 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 finance leases, which are measured using Level 2 inputs, at March 31, 2019 and December 31, 2018 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: March 31, 2019 December 31, 2018 (In thousands) Carrying value $ 250,000 $ 250,000 Fair value 257,055 247,028

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. 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 March 31, 2019 and December 31, 2018, we had approximately $37.6 million and $41.0 million, respectively, of unearned rental revenue included in accrued liabilities in the Condensed Consolidated Balance Sheets for March 31, 2019 and December 31, 2018. We expect to perform the remaining performance obligations and recognize the unearned rental revenue within the next twelve months. 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 include restricted common stock and incremental shares of common stock issuable upon the exercise of stock options. The following table is a reconciliation of net income and weighted-average shares of common stock outstanding for purposes of calculating basic and diluted EPS: Three Months Ended March 31, 2019 2018 (In thousands, except per share data) Numerator: Net income $ 18,085 $ 14,855 Denominator: Weighted average shares outstanding - basic 44,448 44,214 Dilutive effect of share-based awards 429 628 Weighted average shares outstanding - diluted 44,877 44,842 Earnings per share: Basic $ 0.41 $ 0.34 Diluted 0.40 0.33 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 period indicated, or the underlying performance criteria had not yet been met: Three Months Ended March 31, 2019 2018 (In thousands) Stock options 1,504 986 Restricted share awards 75 — Total 1,579 986

Inventory Disclosure [Abstract]
Inventories	(6) 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. 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. Inventories at March 31, 2019 and December 31, 2018 consisted of the following: March 31, 2019 December 31, 2018 (In thousands) Raw materials and supplies $ 7,780 $ 8,078 Finished units 3,922 3,647 Inventories $ 11,702 $ 11,725

Rental Fleet

Rental Fleet	3 Months Ended

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. 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, 2018, management estimates that the net orderly liquidation appraisal value as of March 31, 2019 was approximately $1.1 billion. Our net book value for this fleet as of March 31, 2019 was $0.9 billion.

Debt Disclosure [Abstract]
Debt	(10) Debt Lines of Credit On March 22, 2019, Mobile Mini and certain of its subsidiaries entered into the Second Amended and Restated ABL Credit Agreement dated as of March 22, 2019 (the “New Credit Agreement”) with Deutsche Bank AG New York Branch (“Deutsche Bank”), as administrative agent, and the other lenders party thereto. The New Credit Agreement amended, restated and replaced Mobile Mini’s prior Amended and Restated ABL Credit Agreement dated as of December 14, 2015 (the “Prior Credit Agreement”) with Deutsche Bank, as administrative agent, and the other lenders party thereto. The New Credit Agreement provides for a five year, $1 billion first lien senior secured revolving credit facility, which is for borrowing in U.S. Dollars (the “U.S. Subfacility”), in British Pounds and Euros (the “U.K. Subfacility”), and in Canadian Dollars (the “Canadian Subfacility”). The U.S. Subfacility is subject, among other things, to the terms of a borrowing base calculated as a discount to the value of certain pledged U.S. collateral; the U.K. Subfacility is subject to a similar borrowing base that includes certain pledged U.K. collateral; and the Canadian Subfacility is subject to a similar borrowing base that includes certain pledged Canadian collateral. Under the terms of the New Credit Agreement, certain real property will require an appraisal before the value can be considered in the borrowing base of the respective subfacilities. All three borrowing bases are subject to certain reserves and caps customary for financings of this type. The New Credit Agreement has an accordion feature that permits, under certain conditions, an increase of up to $500 million of additional commitments. If at any time the aggregate amounts outstanding under the subfacilities exceed the respective borrowing base then in effect, a prepayment of an amount sufficient to eliminate such excess is required to be made. Mobile Mini has the right to prepay loans under the New Credit Agreement in whole or in part at any time. All amounts borrowed under the New Credit Agreement must be repaid on or before March 22, 2024. The New Credit Agreement also provides for the issuance of irrevocable standby letters of credit by U.S. lenders in amounts totaling up to $50 million, by U.K.-based lenders in amounts totaling up to $20 million and by Canadian-based lenders in amounts totaling up to $20 million. Loans made under the U.S. Subfacility bear interest at a rate equal to, at Mobile Mini’s option, either (a) the London interbank offered rate (“LIBOR”) plus an applicable margin (“LIBOR Loans”) or (b) the prime rate plus an applicable margin (“Base Rate Loans”). With some exceptions, Mobile Mini may freely convert LIBOR Loans to Base Rate Loans and vice versa. Loans made under the U.K. Subfacility denominated in British Pounds bear interest at a rate equal to the LIBOR plus an applicable margin and loans denominated in Euros bear interest at a rate equal to the Euro interbank offered rate (“EURIBOR”) plus an applicable margin. Loans made under the Canadian Subfacility bear interest at a rate equal to, at Mobile Mini’s option, either (i) the Canadian prime rate plus an applicable margin (“Canadian Prime Rate Loans”) or (ii) the Canadian Dollar bankers’ acceptance rate (“B/A Rate”) plus an applicable margin (“Canadian LIBOR Loans”). With some exceptions, Mobile Mini may freely convert Canadian Prime Rate Loans to Canadian LIBOR Loans and vice versa. The initial applicable margin for loans under the U.S. Subfacility was 0.50% with respect to Base Rate Loans and 1.50% with respect to LIBOR Loans. For loans under the U.K. Subfacility, the initial applicable margin was 1.50%; and for loans under the Canadian Subfacility, the initial applicable margin was 0.50% for Canadian Prime Rate Loans and 1.50% for Canadian LIBOR Loans. The applicable margins will be readjusted quarterly based upon Mobile Mini’s daily average total borrowing availability. Mobile Mini is also required to pay an unused line fee in respect of the unutilized commitments under the New Credit Agreement at a fee rate of 0.225% per annum, as well as customary letter of credit fees. Ongoing extensions of credit under the New Credit Agreement are subject to customary conditions, including sufficient availability under the respective borrowing base. The New Credit Agreement also contains covenants that require Mobile Mini to, among other things, periodically furnish financial and other information to the various lenders. The New Credit Agreement contains customary negative covenants applicable to Mobile Mini and its subsidiaries, including negative covenants that restrict the ability of such entities to, among other things, (i) allow certain liens to attach to Mobile Mini or subsidiary 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, Mobile Mini must comply with a minimum fixed charge coverage ratio of 1.00 to 1.00 as of the last day of each quarter, upon specified excess availability under the New 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. The U.S. Subfacility is guaranteed by Mobile Mini and certain of its domestic subsidiaries. The U.K. Subfacility and the Canadian Subfacility are guaranteed by Mobile Mini and certain of its domestic and foreign subsidiaries. The U.S. Subfacility is secured by a first priority lien on substantially all assets of Mobile Mini and the guarantors of such subfacility; the U.K. Subfacility is secured by a first priority lien on substantially all of the assets of the borrowers and the guarantors of such subfacility; and the Canadian Subfacility is secured by a first priority lien on substantially all of the borrowers and the guarantors of such subfacility. The New Credit Agreement also includes other covenants, representations, warranties, indemnities, and events of default that are customary for facilities of this type, including events of default relating to a change of control of Mobile Mini. 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 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 Finance Leases At March 31, 2019 and December 31, 2018, obligations under finance leases for certain real property and transportation related equipment were $62.4 million and $63.4 million, respectively.

Leases [Abstract]
Leases	(11) Leases Real Estate We lease our corporate and administrative offices in Phoenix, Arizona and our U.K. headquarters in Stockton-on-Tees. We also lease field locations throughout the United States and the U.K., as well as two in Canada. Many real estate leases include one or more options to renew. The exercise of lease renewal options is generally at our discretion and we assess the initial lease term based on the term that we are reasonably certain to occupy the leased property. None of our real estate leases contain residual value guarantees or purchase options. The majority of our real estate leases are operating leases. Equipment Leases Mobile Mini also engages in leases related to ancillary equipment to support our field operations; such as, forklifts, trucks, service vehicles and automobiles. These leases often include an option to purchase the equipment at the end of the lease and are generally finance leases. In addition, we have leases for certain office equipment. Lease Assets and Liabilities For leases with an initial term greater than twelve months, we recognize a lease asset and liability at commencement date. Lease assets are initially measured at cost, which includes the initial amount of the lease liability, plus any initial direct costs incurred, less lease incentives received. In our Condensed Consolidated Balance Sheet, finance lease assets are included in property, plant and equipment. For operating leases, the liability is initially and subsequently measured as the present value of the unpaid lease payments. For finance lease liabilities, the lease liability is also initially measured as the present value of the unpaid lease payments, and is subsequently measured at amortized cost using the effective interest method. Lease Discount Rate – We are required to discount our unpaid fixed lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, our incremental borrowing rate. Our finance leases generally have an interest rate implicit in the lease. For operating leases and certain finance leases, we generally cannot determine the interest rate implicit in the lease, in which case we use our incremental borrowing rate as the discount rate for the lease. We estimate our incremental borrowing rate for these leases based on current rates available to us on finance leases, which are collateralized, have a level payments structure and a specified lease term. Lease Term – Our lease terms include the non-cancellable period of the lease plus any additional periods covered by an extension of the lease that we are reasonably certain to exercise. Fixed Payments – Lease payments included in our measurement of the lease liability include the following: fixed payments owed over the lease term, termination penalties if we expect to exercise a termination option, the price to purchase the underlying asset if we are reasonably certain to exercise the purchase option and residual value guarantees if applicable. Maturity of Lease Liabilities The scheduled maturity for lease liabilities for balances outstanding at March 31, 2019 were as follows: Operating Leases Finance Leases Total (In thousands) 2019 (remaining) $ 14,869 $ 9,210 $ 24,079 2020 16,950 13,084 30,034 2021 14,389 12,649 27,038 2022 13,124 11,275 24,399 2023 11,235 9,545 20,780 Thereafter 35,471 11,835 47,306 Total commitments 106,038 67,598 173,636 Less: interest (14,175 ) (5,218 ) (19,393 ) Present value of lease liabilities $ 91,863 $ 62,380 $ 154,243 The scheduled maturity for lease liabilities at December 31, 2018 were as follows: Operating Leases Finance Leases (In thousands) 2019 $ 18,827 $ 12,055 2020 15,510 12,869 2021 13,324 12,434 2022 12,205 11,060 2023 10,402 9,331 Thereafter 33,440 11,029 Total $ 103,708 68,778 Amount representing interest (5,419 ) Present value of minimum lease payments $ 63,359 Assets recorded under capital lease obligations totaled approximately $90.3 million as of December 31, 2018 and the related accumulated amortization totaled approximately $35.7 million. Lease Expense and Activity Payments due under lease contracts include fixed payments plus, for many of our leases, variable payments. Fixed payments under our leases are recognized on a straight-line basis over the term of the lease, including any periods of free rent. Variable expenses associated with leases are recognized when they are incurred. For our real estate leases, variable payments include such items as allocable property taxes, local sales and business taxes, and common area maintenance charges. Variable payments associated with equipment leases include such items as maintenance services provided by the lessor and local sales and business taxes. We have elected as an accounting policy to not separate lease components and non-lease components. In our Condensed Consolidated Statements of Income, expenses for our operating leases are recognized within rental, selling and general expenses and amortization of assets held under finance leases is included in depreciation and amortization expense. Our lease activity during the three months ended March 31, 2019 was as follows: Expense: Finance lease expense: Amortization of finance lease assets $ 3,423 Interest on obligations under finance leases 430 Total finance lease expense $ 3,853 Operating lease expense: Short-term lease expense $ 324 Fixed lease expense 5,394 Variable lease expense 1,516 Sublease income (25 ) Total operating lease expense $ 7,209 Cash paid and new or modified lease information: Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from finance leases $ 417 Operating cash flows from operating leases, fixed payments 5,331 Financing cash flows from finance leases 2,586 Net assets obtained in exchange for new or modified finance lease liabilities 1,609 Net operating lease assets obtained in exchange for new or modified operating lease liabilities 5,145 Lease Term and Discount Rates Weighted-average remaining lease terms and discount rates as of March 31, 2019 were as follows: Lease terms and discount rates: Weighted-average remaining lease term - finance leases (in years) 4.5 Weighted-average remaining lease term - operating leases (in years) 7.3 Weighted average discount rate - finance leases 2.7 % Weighted average discount rate - operating leases 3.5 %

Income Tax Disclosure [Abstract]
Income Taxes	(12) 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 March 31, 2019, we are no longer subject to examination by U.S. federal tax authorities for years prior to 2015, to examination for any U.S. state taxing authority prior to 2013, or to examination for any foreign jurisdictions prior to 2014. All subsequent periods remain open to examination. Our effective income tax rate increased to 26.5% for the three months ended March 31, 2019, compared to 25.0% for the prior-year quarter. The increase in the effective tax rate was primarily due to the decrease in tax benefits for windfalls (which are tax deductions in excess of GAAP expense) and a reduction in tax deductions for disqualifying dispositions of incentive stock options, both of which are required to be recorded in the quarter that they occur. Uncertain tax positions are recognized and measured using a two-step approach. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation process, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. As of March 31, 2019, the Company did not have any unrecognized tax benefits. 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 Income.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Share-Based Compensation	(13) 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 March 31, 2019, 1.2 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. Service-based awards. We grant share-based compensation awards that vest over time subject to the employee rendering service over the vesting period. The majority of the service–based awards vest in equal annual installments over a period of three to four years. The expense for service-based awards is expensed ratably over the full service period of the grant Performance-based awards . All performance-based awards granted from 2016 through 2019 vest contingently over a three-year period assuming a target number of options or restricted share awards. However, the terms of these awards provide that the number of options or restricted share awards that ultimately vest may vary between 50% and 200% of the target amount, or may be zero. The targets were set at the time of grant. For awards granted from 2016 through 2019, performance conditions are related to the Company’s return on capital employed. Expense related to performance-based awards that have multiple vesting dates, is recognized using the accelerated attribution approach, whereby each vesting tranche is treated as a separate award for purposes of determining the implicit service period. The accelerated attribution approach generally results in a higher expense during the earlier years of vesting. Expense related to performance-based awards is recognized based upon anticipated attainment. For both three-month periods ended March 31, 2019 and 2018 the share-based compensation expense of $3.4 million and $2.2 million, respectively, was recognized in rental, selling and general expenses. As of March 31, 2019, total unrecognized compensation cost related to stock option awards, assuming achievement at target, was approximately $0.3 million and the related weighted-average period over which it is expected to be recognized is approximately 0.9 years. As of March 31, 2019, the unrecognized compensation cost related to restricted stock awards assuming achievement at target was approximately $13.1 million, which is expected to be recognized over a weighted-average period of approximately 2.0 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 2019 or 2018. The following table summarizes stock option activity for the three months ended March 31, 2019: Number of Options Performance-Based Options Service-Based Options Total Options Weighted Average Exercise Price (In thousands) Options outstanding, beginning of period 533 2,421 2,954 $ 32.71 Additional options awarded based upon achievement of specified performance criteria 227 — 227 29.54 Canceled/Expired (7 ) (3 ) (10 ) 35.10 Exercised (24 ) (42 ) (66 ) 25.58 Options outstanding, end of period 729 2,376 3,105 32.62 Unvested target options that vest based upon 2019 performance conditions 114 Due to actual performance exceeding targets, shares granted in 2016 and 2017 that contingently vested based upon 2018 performance criteria vested above target at 200% resulting in additional awards. A summary of stock options outstanding as of March 31, 2019 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 3,105 $ 32.62 4.96 $ 9,272 Exercisable 2,991 32.63 4.85 9,087 The aggregate intrinsic value of options exercised during the three months ended March 31, 2019 was approximately $0.6 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: Number of Shares Performance-Based Awards Service-Based Awards Total Awards Weighted Average Grant Date Fair Value (In thousands) Restricted stock awards at beginning of period 94 233 327 $ 35.06 Awarded 111 111 222 36.79 Additional shares awarded based upon achievement of specified performance criteria 31 — 31 36.41 Released (62 ) (80 ) (142 ) 35.49 Forfeited (1 ) (3 ) (4 ) 35.11 Restricted stock awards at end of period 173 261 434 36.01 Unvested target stock awards that vest based upon 2019 performance conditions 68 Unvested target stock awards that vest based upon 2020 performance conditions 68 Unvested target stock awards that vest based upon 2021 performance conditions 37 Due to actual performance exceeding targets, shares granted in 2018 that contingently vested based upon 2018 performance criteria vested above target at 200% resulting in additional share awards.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	(15) 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.

The share repurchase program does not have an expiration date and may be suspended or terminated at any time by the Board. All shares repurchased are held in treasury. During the three months ended March 31, 2019, 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 March 31, 2019. We withheld approximately 29,000 shares of stock from employees, for an approximate value of $1.1 million, upon vesting of share awards to satisfy tax withholding obligations during the three months ended March 31, 2019.

Segment Reporting [Abstract]
Segment Reporting	(17) 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 $128.0 million and $117.7 million for the three months ended March 31, 2019 and 2018, 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 March 31, 2019 Storage Solutions North America United Kingdom Total Tank & Pump Solutions Consolidated (In thousands) Revenues: Rental $ 93,516 $ 19,209 $ 112,725 $ 29,447 $ 142,172 Sales 4,026 1,751 5,777 1,446 7,223 Other 225 — 225 41 266 Total revenues 97,767 20,960 118,727 30,934 149,661 Costs and expenses: Rental, selling and general expenses 58,956 13,670 72,626 19,608 92,234 Cost of sales 2,413 1,403 3,816 786 4,602 Depreciation and amortization 8,989 1,734 10,723 6,612 17,335 Total costs and expenses 70,358 16,807 87,165 27,006 114,171 Income from operations $ 27,409 $ 4,153 $ 31,562 $ 3,928 $ 35,490 Interest expense, net of interest income $ 7,930 $ 135 $ 8,065 $ 2,695 $ 10,760 Income tax provision 5,395 764 6,159 364 6,523 Capital expenditures for additions to rental fleet, excluding acquisitions 11,841 921 12,762 10,254 23,016 For the Three Months Ended March 31, 2018 Storage Solutions North America United Kingdom Total Tank & Pump Solutions Consolidated (In thousands) Revenues: Rental $ 86,598 $ 20,266 $ 106,864 $ 25,474 $ 132,338 Sales 4,876 1,863 6,739 1,364 8,103 Other 129 40 169 44 213 Total revenues 91,603 22,169 113,772 26,882 140,654 Costs and expenses: Rental, selling and general expenses 57,018 13,806 70,824 18,174 88,998 Cost of sales 3,024 1,545 4,569 822 5,391 Restructuring expenses 111 — 111 — 111 Depreciation and amortization 8,682 2,050 10,732 6,091 16,823 Total costs and expenses 68,835 17,401 86,236 25,087 111,323 Income from operations $ 22,768 $ 4,768 $ 27,536 $ 1,795 $ 29,331 Interest expense, net of interest income $ 6,686 $ 206 $ 6,892 $ 2,701 $ 9,593 Income tax provision (benefit) 4,597 818 5,415 (466 ) 4,949 Capital expenditures for additions to rental fleet, excluding acquisitions 8,279 3,574 11,853 3,536 15,389 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 March 31, 2019: Goodwill $ 468,495 $ 56,928 $ 525,423 $ 181,216 $ 706,639 Intangibles, net 773 324 1,097 52,870 53,967 Rental fleet, net 664,268 143,821 808,089 135,848 943,937 As of December 31, 2018: Goodwill $ 468,400 $ 55,601 $ 524,001 $ 181,216 $ 705,217 Intangibles, net 859 341 1,200 54,342 55,542 Rental fleet, net 657,459 140,636 798,095 130,995 929,090 Included in the table above are assets in the U.S. of $1.5 billion as of both March 31, 2019 and December 31, 2018.

Separate financial statements of the subsidiary guarantors are not presented because the guarantee by each 100% owned subsidiary guarantor is full and unconditional, joint and several, subject to customary exceptions, and management has determined that such information is not material to investors.

Mobile Mini, Inc. - Organization and Description of Business (Policies)	3 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 months ended March 31, 2019 and 2018, respectively, are not necessarily indicative of the results to be expected for the full 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, 2018 filed with the Securities and Exchange Commission (“SEC”) on February 5, 2019.
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 include 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. 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 three months ended March 31, 2019 and 2018 was $8.0 million and $7.2 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 $128.0 million and $117.7 million for the three months ended March 31, 2019 and 2018, 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 (the “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. 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 adopted this standard effective January 1, 2019, utilizing a modified retrospective transition approach. We chose to use the effective date as our date of initial application. Consequently, financial information was not updated and the disclosures required under the new standard were not provided for dates and periods before January 1, 2019. The standard includes optional transition practical expedients intended to simplify its adoption. We elected to adopt the package of practical expedients, which allowed us to retain the historical lease classification determined under legacy GAAP as well as a relief from reviewing expired or existing contracts to determine if they contain leases. Upon adoption, we recognized operating lease liabilities totaling approximately $91 million, with corresponding right of use assets. The liabilities were calculated as the present value of the remaining minimum rental payments for existing operating leases. When we enter contractual arrangements as lessor, we expect the period of each rental to be less than one year. As such, the accounting for contracts in which we are the lessor is not affected. This standard did not materially impact our consolidated net earnings and had no impact on cash flows. See Note 11 for additional information.
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.
