Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Organization and Nature of Operations WillScot Corporation (“WillScot” and, together with its subsidiaries, the “Company”) is a leading provider of modular space and portable storage solutions in the United States (“US”), Canada and Mexico. The Company leases, sells, delivers and installs mobile offices, modular buildings and storage products through an integrated network of branch locations that spans North America. WillScot was incorporated as a Cayman Islands exempt company under the name Double Eagle Acquisition Corporation ("Double Eagle") on June 26, 2015. Prior to November 29, 2017, Double Eagle was a Nasdaq-listed special purpose acquisition company formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination. On November 29, 2017, Double Eagle indirectly acquired Williams Scotsman International, Inc. (“WSII”) from Algeco Scotsman Global S.à r.l. (together with its subsidiaries, the “Algeco Group”), which was majority owned by an investment fund managed by TDR Capital LLP ("TDR Capital"). As part of the transaction, Double Eagle domesticated to Delaware and changed its name to WillScot Corporation. WillScot, whose Class A common shares are listed on the Nasdaq Capital Market (Nasdaq: WSC), serves as the holding company for the Williams Scotsman family of companies. All of the Company’s assets and operations are owned through Williams Scotsman Holdings Corp. (“WS Holdings”). WillScot operates a nd owns 91.0% of WS Holdings, and Sapphire Holding S.à r.l. (“Sapphire”), an affiliate of TDR Capital, owns the remaining 9.0%. Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Quarterly Report on Form 10-Q and do not include all the information and notes required by accounting principles generally accepted in the US (“GAAP”) for complete financial statements. The accompanying unaudited condensed consolidated financial statements comprise the financial statements of WillScot and its subsidiaries that it controls due to ownership of a majority voting interest and contain all adjustments, which are of a normal and recurring nature, necessary to present fairly the financial position, the results of operations and cash flows for the interim periods presented. On December 31, 2019, the 2019 financial statement amounts were adjusted for the adoption Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) ("ASC 842"), effective retroactively to January 1, 2019, and therefore may not agree to the Quarterly Reports filed on Form 10-Q for the respective periods of 2019. Subsidiaries are fully consolidated from the dat e of acquisition, being the date on which the Company obtains control, and continue to be consolidated until the date when such control ceases. The financial statements of the subsidiaries are prepared for the same reporting period as the Company. All intercompany balances and transactions are eliminated. The results of operations for the three months ended March 31, 2020 are not necessarily indicative of the results to be expected for the full year. For further information, refer to the consolidated financial statements and notes included in WillScot's Annual Report on Form 10-K for the year ended December 31, 2019 . Recently Issued and Adopted Accounting Standards Recently Issued Accounting Standards In March 2020, the Financial Accounting Standards Board (“FASB”) issued ASU 2020-04, Reference Rate Reform (Topic 848) , which is elective, and provides for optional expedients and exceptions for applying GAAP to contracts, hedging relationsh ips, and other transactions affected by reference rate reform if certain criteria are met. The Company is currently evaluating the impact of reference rate reform and potential impact of adoption of these elective practical expedients on its condensed consolidated financial statements and will consider the impact of adoption during its analysis. Recently Adopted Accounting Standards In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) ("ASC 326"), which prescribes that financial assets (or a group of financial assets) should be measured at amortized cost basis to be presented at the net amount expected to be collected based on relevant historical information from historical experience, adjusted for current conditions and reasonable and supportable forecasts that affect collectibility. Credit losses relating to these financial assets are recorded through an allowance for credit losses. The Company adopted ASC 326 effective January 1, 2020. The effect of this guidance was immaterial to the Company's consolidated results of operations, financial position and cash flows. Impact of COVID-19 In December 2019, a novel strain of coronavirus, COVID-19, was first detected in Wuhan, China, and it has since spread to other regions, including the United States. On March 11, 2020, the World Health Organization declared that the rapidly spreading COVID-19 outbreak was a global pandemic. In response to the pandemic, many governments around the world are implementing a variety of measures to reduce the spread of COVID-19, including travel restrictions and bans, instructions to residents to practice social distancing, quarantine advisories, shelter-in-place orders and required closures of non-essential businesses. There have been significant changes to the global economic situation and to public securities markets as a consequence of the COVID-19 pandemic. It is reasonably likely that this could cause changes to estimates as a result of the markets in which the Company operates, the price of the Company’s publicly traded equity and debt in comparison to the Company’s carrying value, and the health of the global economy. Such changes to estimates could potentially result in impacts that would be material to the consolidated financial statements, particularly with respect to the fair value of the Company’s reporting units in relation to potential goodwill impairment, the fair value of long-lived assets in relation to potential impairment and the allowance for doubtful accounts. On March 27, 2020, President Trump signed into law the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”). The CARES Act provides several employer and corporate incentives designed to assist businesses with liquidity and support employee retention. The Company continues to assess the implications of the CARES Act to its business and believes that relevant components of the CARES Act are not material to its financial statements as a whole.

Acquisitions and Assets Held for Sale	Acquisitions and Assets Held for Sale Pending Mobile Mini Merger On March 1, 2020, the Company, along with its newly formed subsidiary, Picasso Merger Sub, Inc. (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Mobile Mini, Inc. (“Mobile Mini”). The Merger Agreement provides for the merger of Mobile Mini with and into Merger Sub (the “Merger”), with Mobile Mini surviving as a wholly-owned subsidiary of the Company. At the effective time of the Merger, and subject to the terms and conditions set forth in the Merger Agreement, each outstanding share of the common stock of Mobile Mini shall be converted into the right to receive 2.4050 shares of WillScot Class A common stock. The Merger has been approved by the boards of directors of the Company and Mobile Mini. The Merger is subject to customary closing conditions, including receipt of regulatory approval and approval by the stockholders of the Company and Mobile Mini and is expected to close in the third quarter of 2020. Additionally, the transaction has the support of TDR Capital, the Company's largest stockholder, which has entered into a voting agreement in support of the Merger. In connection with the Merger, the Company entered into a commitment letter (the “Commitment Letter”), dated March 1, 2020, as amended and restated on March 24, 2020, and further amended and restated on May 5, 2020, with the lenders party thereto (the “Lenders”). Pursuant to the Commitment Letter, the Lenders have agreed to provide debt financing to refinance the Company’s existing ABL Facility (as defined in Note 9), Mobile Mini’s existing ABL credit facility and Mobile Mini’s outstanding senior notes due 2024 on the terms and conditions set forth in the Commitment Letter. The Company expensed $9.4 million in transaction costs related to the Merger within selling, general and administrative ("SG&A") for the three months ended March 31, 2020. Assets Held for Sale As part of the Modular Space Holdings, Inc. ("ModSpace") acquisition in 2018, the Company implemented a plan to right size its branch network and dispose of unused properties. As of March 31, 2020, the Company had five properties totaling $8.5 million included in assets held for sale. During the three months ended March 31, 2020, the Company recorded no impairment related to these assets. As of March 31, 2019, the Company had ten properties totaling $21.0 million included in assets held for sale. During the three months ended March 31, 2019, the Company recorded an impairment of $2.3 million related to assets held for sale. The fair value of the assets held for sale was determined using valuations from third party brokers, which were based on current sales prices for comparable assets, a Level 2 measurement.

(b) Primarily damage billings, delinquent payment charges, and other processing fees. Modular Leasing and Services Revenue The majority of revenue (72% for the three months ended March 31, 2020 an d 68% fo r the three months ended March 31, 2019 ) is generated by rental income subject to the guidance of ASC 842. The remaining revenue for the three months ended March 31, 2020 and 2019 is generated by performance obligations in contracts with customers for services or sale of units subject to the guidance in ASU 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASC 606"). Receivables, Contract Assets and Liabilities As reflected above, approximately 72% of the Company's rental revenue is generated by lease revenue subject to the guidance of ASC 842. The customers that are responsible for the remaining revenue that is accounted for under ASC 606 are generally the same customers that rent the Company's equipment. We manage credit risk associated with our accounts receivables at the customer level. Because the same customers generate the revenues that are accounted for under both Topic 606 and Topic 840, the discussions below on credit risk and our allowance for doubtful accounts address our total revenues. The Company's top five customers with the largest open receivables balances represented 4.7% of the total receivables balance as of March 31, 2020. As of December 31, 2019, the Company had approximately $42.6 million of deferred revenue that relates to removal services for lease transactions and advance billings for sale transactions, which are within the scope of ASC 606. As of March 31, 2020, the Company had approximately $44.6 million of deferred revenue relating to these services which are included in deferred revenue and customer deposits in the condensed consolidated balance sheets. During the three months ended March 31, 2020, $7.9 million of previously deferred revenue relating to removal services for lease transactions and advance billings for sale transactions was recognized as revenue. The Company does not have material contract assets and it did not recognize any material impairments of any contract assets. The Company's uncompleted contracts with customers have unsatisfied (or partially satisfied) performance obligations. For the future services revenues that are expected to be recognized within twelve months, the Company has elected to utilize the optional disclosure exemption made available regarding transaction price allocated to unsatisfied (or partially unsatisfied) performance obligations. The transaction price for performance obligations that will be completed in greater than twelve months is variable based on the costs ultimately incurred to provide those services and therefore the Company is applying the optional exemption to omit disclosure of such amounts. The primary costs to obtain contracts for new and rental unit sales with the Company's customers are commissions. The Company pays its sales force commissions on the sale of new and rental units. For new and rental unit sales, the period benefited by each commission is less than one year. As a result, the Company has applied the practical expedient for incremental costs of obtaining a sales contract and will expense commissions as incurred.

Fair Value Measures	Fair Value Measures The fair value of financial assets and liabilities are included at the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. The Company utilizes the suggested accounting guidance for the three levels of inputs that may be used to measure fair value: 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 The Company has assessed that the fair value of cash and cash equivalents, trade receivables, trade payables, capital lease and other financing obligations, and other current liabilities approximate their carrying amounts. The following table shows the carrying amounts and fair values of financial assets and liabilities, including their levels in the fair value hierarchy: March 31, 2020 December 31, 2019 Carrying Amount Fair Value Carrying Amount Fair Value (in thousands) Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 US ABL Facility $ 877,589 $ — $ 893,500 $ — $ 885,245 $ — $ 903,000 $ — Canadian ABL Facility — — — — — — — — 2022 Secured Notes 264,982 — 262,429 — 264,576 — 282,250 — 2023 Secured Notes 483,201 — 473,498 — 482,768 — 517,334 — Total $ 1,625,772 $ — $ 1,629,427 $ — $ 1,632,589 $ — $ 1,702,584 $ — The carrying value of the US ABL Facility, the 2022 Secured Notes and the 2023 Secured Notes includes $15.9 million, $5.0 million and $6.8 million, respectively, of unamortized debt issuance costs as of March 31, 2020, which are presented as a direct reduction of the corresponding liability.

Segment Reporting	Segment Reporting The Company operates in one principal line of business: modular leasing and sales. Modular leasing and sales is comprised of two operating segments: US and Other North America. The US modular operating segment (“Modular - US”) consists of the contiguous 48 states and Hawaii. The Other North America operating segment (“Modular - Other North America”) consists of Alaska, Canada and Mexico. Total assets for each reportable segment are not available because the Company utilizes a centralized approach to working capital management. Transactions between reportable segments are not significant. The Chief Operating Decision Maker ("CODM") evaluates business segment performance on Adjusted EBITDA, which excludes certain items as shown in the reconciliation of the Company’s consolidated net loss before tax to Adjusted EBITDA below. Management believes that evaluating segment performance excluding such items is meaningful because it provides insight with respect to intrinsic operating results of the Company. The Company also regularly evaluates gross profit by segment to assist in the assessment of its operational performance. The Company considers Adjusted EBITDA to be the more important metric because it more fully captures the business performance of the segments, inclusive of indirect costs. Reportable Segments The following tables set forth certain information regarding each of the Company’s reportable segments fo r the three months ended March 31, 2020 and 2019, respectively. Three Months Ended March 31, 2020 (in thousands) Modular - US Modular - Other North America Total Revenues: Leasing and services revenue: Modular leasing $ 172,575 $ 15,777 $ 188,352 Modular delivery and installation 47,617 3,453 51,070 Sales revenue: New units 9,267 346 9,613 Rental units 4,405 2,381 6,786 Total revenues 233,864 21,957 255,821 Costs: Cost of leasing and services: Modular leasing 46,884 2,925 49,809 Modular delivery and installation 40,706 3,159 43,865 Cost of sales: New units 6,007 196 6,203 Rental units 2,305 1,501 3,806 Depreciation of rental equipment 41,653 4,295 45,948 Gross profit $ 96,309 $ 9,881 $ 106,190 Other selected data: Adjusted EBITDA $ 81,685 $ 7,859 $ 89,544 Selling, general and administrative expense $ 68,663 $ 6,305 $ 74,968 Other depreciation and amortization $ 2,877 $ 197 $ 3,074 Purchases of rental equipment and refurbishments $ 37,006 $ 2,642 $ 39,648 Three Months Ended March 31, 2019 (in thousands) Modular - US Modular - Other North America Total Revenues: Leasing and services revenue: Modular leasing $ 161,885 $ 15,407 $ 177,292 Modular delivery and installation 46,006 3,994 50,000 Sales revenue: New units 13,961 880 14,841 Rental units 8,323 3,229 11,552 Total revenues 230,175 23,510 253,685 Costs: Cost of leasing and services: Modular leasing 43,883 3,352 47,235 Modular delivery and installation 39,751 3,592 43,343 Cost of sales: New units 10,250 628 10,878 Rental units 5,869 1,926 7,795 Depreciation of rental equipment 36,474 4,629 41,103 Gross profit $ 93,948 $ 9,383 $ 103,331 Other selected data: Adjusted EBITDA $ 75,946 $ 7,408 $ 83,354 Selling, general and administrative expense $ 65,930 $ 7,389 $ 73,319 Other depreciation and amortization $ 2,574 $ 210 $ 2,784 Purchases of rental equipment and refurbishments $ 49,921 $ 1,952 $ 51,873 The following tables present a reconciliation of the Company’s (loss) income from operations before income tax to Adjusted EBITDA by segment for the three months ended March 31, 2020 and 2019, respectively: Three Months Ended March 31, 2020 (in thousands) Modular - US Modular - Other North America Total (Loss) income from operations before income taxes $ (4,273) $ 1,389 $ (2,884) Interest expense 27,928 329 28,257 Depreciation and amortization 44,530 4,492 49,022 Currency (gains) losses, net (525) 1,423 898 Restructuring costs, lease impairment expense and other related charges 1,355 246 1,601 Transaction costs 9,431 — 9,431 Integration costs 1,696 (11) 1,685 Stock compensation expense 1,787 — 1,787 Other income (244) (9) (253) Adjusted EBITDA $ 81,685 $ 7,859 $ 89,544 Three Months Ended March 31, 2019 (in thousands) Modular - US Modular - Other North America Total (Loss) income from operations before income taxes $ (10,044) $ 393 $ (9,651) Interest expense 30,582 533 31,115 Depreciation and amortization 39,047 4,840 43,887 Currency gains, net (130) (186) (316) Restructuring costs, lease impairment expense and other related charges 4,177 564 4,741 Goodwill and other impairments 1,801 489 2,290 Integration costs 9,352 786 10,138 Stock compensation expense 1,290 — 1,290 Other income (129) (11) (140) Adjusted EBITDA $ 75,946 $ 7,408 $ 83,354

Loss Per Share

Loss Per Share	3 Months Ended
	Mar. 31, 2020
Earnings Per Share [Abstract]
Loss Per Share	Loss Per Share Basic loss per share (“EPS”) is calculated by dividing net loss attributable to WillScot by the weighted average number of Class A common shares outstanding during the period. The common shares issued as a result of the vesting of RSUs and for warrants exercised or redeemed during the three months ended March 31, 2020, were included in EPS based on the weighted average number of days in which they were vested and outstanding during the period. Class B common shares have no rights to dividends or distrib utions made by the Company and, in turn, are excluded from the EPS calculation. Pursuant to the exchange agreement entered into by WS Holding's shareholders, Sapphire has the right, but not the obligation, to exchange all, but not less than all, of its shares of WS Holdings into newly issued shares of WillScot’s Class A common stock in a private placement transaction. In connection with the pending Merger, Sapphire has agreed to exchange all of its shares of common stock, par value $0.0001 per share, of WS Holdings, immediately prior to the effective time of the Merger, for shares of WillScot's Class A common stock, at an exchange ratio of 1.3261 times, without any subsequent adjustment. As a result of such exchange, at the effective time of the Merger, all issued and outstanding shares of the Company's Class B common stock (which are held by Sapphire) will be cancelled. The effect of the cancellation of shares of Class B common stock would be anti-dilutive for the three months ended March 31, 2020 and 2019. Diluted EPS is computed similarly to basic EPS, except that it includes the potential dilution that could occur if dilutive securities were exercised. Effects of potentially dilutive securities are presented only in periods in which they are dilutive. Stock options, Time-Based RSUs, RSAs, and warrants representing 534,188, 900,541, 52,755, and 18,746,920 shares of Class A common stock outstanding for the three months ended March 31, 2020 were excluded from the computation of diluted earnings per share because their effect would have been anti-dilutive. Market-Based RSUs representing 578,886 shares of Class A common stock outstanding for the three months ended March 31, 2020, which can vest at 0% to 150% of the amount granted, were excluded from the computation of diluted earnings per share because their effect would have been anti-dilutive. Stock options, Time-Based RSUs, RSAs, and warrants representing 589,257, 1,117,953, 44,378 and 22,183,513 shares of Class A common stock outstanding for the three months ended March 31, 2019, were excluded from the computation of diluted earnings per share because their effect would have been anti-dilutive. Market-Based RSUs representing 302,182 shares of Class A common stock outstanding for the three months ended March 31, 2019, which can vest at 0% to 150% of the amount granted, were excluded from the computation of diluted earnings per share because their effect would have been anti-dilutive.

On August 22, 2018, WillScot’s majority stockholder, Sapphire, entered into a margin loan (the "Margin Loan") under which all of its WillScot Class A common stock was pledged to secure $125.0 million of borrowings under the loan agreement. WillScot is not a party to the loan agreement and has no obligations thereunder, but WillScot delivered an issuer agreement to the lenders under which WillScot has agreed to certain obligations relating to the shares pledged by Sapphire and, subject to applicable law and stock exchange rules, not to take any actions that are intended to materially hinder or delay the exercise of any remedies with respect to the pledged shares. In connection with the Margin Loan, on August 24, 2018, WSII entered into a two-year supply agreement with Target Logistics Management LLC, an affiliate controlled by Sapphire, under which, subject to limited exceptions, WSII acquired the exclusive right to supply modular units, portable storage units, and other ancillary products ordered by the affiliate in the US. As of March 31, 2020, the 49,053,740 shares of WillScot Class A common stock pledged by Sapphire represented approximately 44.4% of WillScot’s issued and outstanding Class A shares. The Company had capital expenditures of rental equipment purchased from related party affiliates of $0.2 million and $1.5 million for three months ended March 31, 2020 and 2019, respectively.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Quarterly Report on Form 10-Q and do not include all the information and notes required by accounting principles generally accepted in the US (“GAAP”) for complete financial statements. The accompanying unaudited condensed consolidated financial statements comprise the financial statements of WillScot and its subsidiaries that it controls due to ownership of a majority voting interest and contain all adjustments, which are of a normal and recurring nature, necessary to present fairly the financial position, the results of operations and cash flows for the interim periods presented. On December 31, 2019, the 2019 financial statement amounts were adjusted for the adoption Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) ("ASC 842"), effective retroactively to January 1, 2019, and therefore may not agree to the Quarterly Reports filed on Form 10-Q for the respective periods of 2019. Subsidiaries are fully consolidated from the dat e of acquisition, being the date on which the Company obtains control, and continue to be consolidated until the date when such control ceases. The financial statements of the subsidiaries are prepared for the same reporting period as the Company. All intercompany balances and transactions are eliminated. The results of operations for the three months ended March 31, 2020 are not necessarily indicative of the results to be expected for the full year. For further information, refer to the consolidated financial statements and notes included in WillScot's Annual Report on Form 10-K for the year ended December 31, 2019 .
Recently Issued and Adopted Accounting Standards	Recently Issued Accounting Standards In March 2020, the Financial Accounting Standards Board (“FASB”) issued ASU 2020-04, Reference Rate Reform (Topic 848) , which is elective, and provides for optional expedients and exceptions for applying GAAP to contracts, hedging relationsh ips, and other transactions affected by reference rate reform if certain criteria are met. The Company is currently evaluating the impact of reference rate reform and potential impact of adoption of these elective practical expedients on its condensed consolidated financial statements and will consider the impact of adoption during its analysis. Recently Adopted Accounting Standards In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) ("ASC 326"), which prescribes that financial assets (or a group of financial assets) should be measured at amortized cost basis to be presented at the net amount expected to be collected based on relevant historical information from historical experience, adjusted for current conditions and reasonable and supportable forecasts that affect collectibility. Credit losses relating to these financial assets are recorded through an allowance for credit losses. The Company adopted ASC 326 effective January 1, 2020. The effect of this guidance was immaterial to the Company's consolidated results of operations, financial position and cash flows.
Impact of COVID-19	In December 2019, a novel strain of coronavirus, COVID-19, was first detected in Wuhan, China, and it has since spread to other regions, including the United States. On March 11, 2020, the World Health Organization declared that the rapidly spreading COVID-19 outbreak was a global pandemic. In response to the pandemic, many governments around the world are implementing a variety of measures to reduce the spread of COVID-19, including travel restrictions and bans, instructions to residents to practice social distancing, quarantine advisories, shelter-in-place orders and required closures of non-essential businesses. There have been significant changes to the global economic situation and to public securities markets as a consequence of the COVID-19 pandemic. It is reasonably likely that this could cause changes to estimates as a result of the markets in which the Company operates, the price of the Company’s publicly traded equity and debt in comparison to the Company’s carrying value, and the health of the global economy. Such changes to estimates could potentially result in impacts that would be material to the consolidated financial statements, particularly with respect to the fair value of the Company’s reporting units in relation to potential goodwill impairment, the fair value of long-lived assets in relation to potential impairment and the allowance for doubtful accounts. On March 27, 2020, President Trump signed into law the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”). The CARES Act provides several employer and corporate incentives designed to assist businesses with liquidity and support employee retention. The Company continues to assess the implications of the CARES Act to its business and believes that relevant components of the CARES Act are not material to its financial statements as a whole.
