Revenue	Revenue Revenue Disaggregation Geographic Areas The Company had total revenue in the following geographic areas for the three months ended March 31, as follows: Three Months Ended (in thousands) 2023 2022 US $ 533,174 $ 421,684 Canada 26,941 25,273 Mexico 5,353 4,214 Total revenues $ 565,468 $ 451,171 Major Product and Service Lines Equipment leasing is the Company's core business and the primary driver of the Company's revenue and cash flows. This includes modular space and portable storage units along with value-added products and services ("VAPS"), which include furniture, steps, ramps, basic appliances, internet connectivity devices, integral tool racking, heavy duty capacity shelving, workstations, electrical and lighting products and other items used by customers in connection with the Company's products. The Company also offers its lease customers a damage waiver program that protects them in case the leased unit is damaged. Leasing is complemented by new unit sales and sales of rental units. In connection with its leasing and sales activities, the Company provides services including delivery and installation, maintenance and ad hoc services and removal services at the end of lease transactions. The Company’s revenue by major product and service line for the three months ended March 31, was as follows: Three Months Ended (in thousands) 2023 2022 Modular space leasing revenue $ 224,470 $ 190,390 Portable storage leasing revenue 97,315 70,703 VAPS and third party leasing revenues (a) 94,126 75,305 Other leasing-related revenue (b) 24,040 15,161 Leasing revenue 439,951 351,559 Delivery and installation revenue 106,630 85,539 Total leasing and services revenue 546,581 437,098 New unit sales revenue 10,657 5,787 Rental unit sales revenue 8,230 8,286 Total revenues $ 565,468 $ 451,171 (a) Includes $5.6 million and $5.9 million of service revenue for the three months ended March 31, 2023 and 2022, respectively. (b) Includes primarily damage billings, delinquent payment charges, and other processing fees. Leasing and Services Revenue The majority of r evenue (77% for the both the three months ended March 31, 2023 and March 31, 2022 ) was generated by rental income subject to the guidance of ASU 2018-11, Leases (Topic 842) ("ASC 842"). The remaining revenue was generated by performance obligations in contracts with customers for services or sale of units subject to the guidance in ASC 606. Receivables and Credit Losses The Company is exposed to credit losses from trade receivables and manages credit risk at the customer level. Because the same customers generate the revenues that are accounted for under both ASC 606 and ASC 842, the discussions below on credit risk and the Company's allowance for credit losses address the Company's total revenues. Concentration of credit risk with respect to the Company's receivables is limited because of a large number of geographically diverse customers who operate in a variety of end user markets. The Company assesses each customer’s ability to pay for the products it leases or sells by conducting a credit review that considers expected billing exposure, timing for payment and the customer’s established credit rating. The Company performs its credit review of new customers at inception of the customer relationship and for existing customers when the customer transacts after a defined period of dormancy. The Company also considers contract terms and conditions, country risk and business strategy in the evaluation. The Company monitors ongoing credit exposure through an active review of customer balances against contract terms and due dates and may employ collection agencies and legal counsel to pursue recovery of defaulted receivables. The allowance for credit losses reflects the estimate of the amount of receivables that the Company will be unable to collect based on historical collection experience and, as applicable, current conditions and reasonable and supportable forecasts that affect collectability. The Company's estimate reflects changing circumstances, including changes in the economy or in the particular circumstances of individual customers. Accordingly, the Company may be required to increase or decrease its allowance. Activity in the allowance for credit losses was as follows: Three Months Ended (in thousands) 2023 2022 Balance at beginning of period $ 57,048 $ 45,773 Provision for credit losses, net of recoveries 8,803 8,311 Write-offs (4,537) (7,010) Foreign currency translation and other 88 50 Balance at end of period $ 61,402 $ 47,124 Contract Assets and Liabilities When customers are billed in advance for services, the Company defers recognition of revenue until the related services are performed, which generally occurs at the end of the contract. The balance sheet classification of deferred revenue is determined based on the contractual lease term. For contracts that continue beyond their initial contractual lease term, revenue continues to be deferred until the services are performed. During the three months ended March 31, 2023, deferred revenue relating to services billed in advance of $27.7 million was recognized as revenue. As of March 31, 2023 and December 31, 2022, the Company had approximately $99.0 million and $102.2 million , respectively, of deferred revenue related to these services. The Company does not have material contract assets, and 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 Compa ny 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 market rate in place at the time those services are provided, and therefore, the Company is applying the optional expedient to omit disclosure of such amounts. The primary costs to obtain contracts fo r 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; therefore, the commissions are expensed as incurred.

No related debt issuance costs were recorded as a direct offset against the principal borrowings on the Multicurrency Facility, and the $2.4 million and $2.5 million in excess of principal was included in other non-current assets on the condensed consolidated balance sheets as of March 31, 2023 and December 31, 2022, respectively. Asset Backed Lending Facility On July 1, 2020, certain subsidiaries of the Company entered into an asset-based credit agreement (the "ABL Facility") that initially provided for revolving credit facilities in the aggregate principal amount of up to $2.4 billion, consisting of: (i) a senior secured asset-based US dollar revolving credit facility in the aggregate principal amount of $2.0 billion and (ii) a $400.0 million senior secured asset-based multicurrency revolving credit facility available to be drawn in US Dollars, Canadian Dollars, British Pounds Sterling or Euros. The ABL Facility was initially scheduled to mature on July 1, 2025. On June 30, 2022, certain subsidiaries of the Company entered into an amendment to the ABL Facility to, among other things, extend the expiration date until June 30, 2027 and increase the aggregate principal amount of the revolving credit facilities to $3.7 billion, consisting of: (i) a senior secured asset-based US dollar revolving credit facility in the aggregate principal amount of $3.3 billion (the “US Facility”) and (ii) a $400.0 million senior secured asset-based multicurrency revolving credit facility (the "Multicurrency Facility"), available to be drawn in US Dollars, Canadian Dollars, British Pounds Sterling or Euros. The amendment also converted the interest rate for borrowings denominated in US Dollars from a LIBOR-based rate to a Term-SOFR-based rate with an interest period of one month and adjusted the applicable margins. The applicable margin for Canadian BA rate, Term SOFR, British Pounds Sterling and Euros loans is 1.50%. The facility includes a credit spread adjustment of 0.10% in addition to the applicable margin. The applicable margin for base rate and Canadian Prime Rate loans is 0.50%. The applicable margins are subject to one step down of 0.25% based on excess availability or one step up of 0.25% based on the Company's leverage ratio. The ABL Facility requires the payment of a commitment fee on the unused available borrowings of 0.20% annually. The weighted average interest rate on the balance outstanding as of March 31, 2023, as adjusted for the effects of the interest rate swap agreements, was 6.52%. Refer to Note 12 for a more detailed discussion on interest rate management. Borrowing availability under the US Facility and the Multicurrency Facility is equal to the lesser of (i) the aggregate Revolver Commitments and (ii) the Borrowing Base ("Line Cap").

Borrowing capacity under the ABL Facility is made available for up to $205.6 million of letters of credit and up to $200.5 million of swingline loans. At March 31, 2023, letters of credit and bank guarantees carried fees of 1.625%. The Company had issued $14.4 million of standby letters of credit under the ABL Facility at March 31, 2023.

Equity	Equity Common Stock In connection with the stock compensation vesting events and stock option exercises described in Note 14, the Company issued 360,725 shares of Common Stock during the three months ended March 31, 2023 . Stock Repurchase Program In July 2022, the Board of Directors approved an increase to the share repurchase program authorizing the Company to repurchase up to $1.0 billion of its outstanding shares of Common Stock and equivalents. The stock repurchase program does not obligate the Company to purchase any particular number of shares, and the timing and exact amount of any repurchases will depend on various factors, including market pricing, business, legal, accounting, and other considerations. In August 2022, the Inflation Reduction Act of 2022 was enacted into law and imposed a nondeductible 1% excise tax on the net value of certain stock repurchases made after December 31, 2022. In the first quarter of 2023, the Company reflected the applicable excise tax in equity as part of the cost basis of the stock repurchased and recorded a corresponding liability for the excise taxes payable in accrued expenses on the consolidated balance sheet. During the three months ended March 31, 2023 , the Company repurchased 4,589,308 shares of Common Stock for $215.7 million, excluding excise tax. As of March 31, 2023, $415.1 million of the approved share repurchase pool remained available.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives In 2018, the Company entered into an interest rate swap agreement with a financial counterparty that effectively converted $400.0 million in aggregate notional amount of variable-rate debt under the Company’s former asset backed lending facility into fixed-rate debt. Under the terms of the agreement, the Company received a floating rate equal to one-month LIBOR and made payments based on a fixed rate of 3.06% on the notional amount. The swap agreement was designated and qualified as a hedge of the Company’s exposure to changes in interest payment cash flows created by fluctuations in variable interest rates on the former asset backed lending facility and terminated on May 29, 2022. In January 2023, the Company entered into two interest rate swap agreements with financial counterparties relating to $750.0 million in aggregate notional amount of variable-rate debt under the Company’s ABL Facility. Under the terms of the agreements, the Company receives a floating rate equal to one-month term SOFR and makes payments based on a weighted average fixed interest rate of 3.44% on the notional amount. The swap agreements were designated and qualified as hedges of the Company’s exposure to changes in interest payment cash flows created by fluctuations in variable interest rates on the ABL Facility. The swap agreements terminate on June 30, 2027. The floating rate that the Company receives under the terms of these swap agreements was 4.79% at March 31, 2023.

The price was dependent upon the date of the closing of the sale. This contract, which was to expire on September 11, 2023, mitigated the foreign currency risk of the USD relative to the British Pound Sterling prior to the closing of the sale of the former UK Storage Solutions segment. This contract did not qualify for hedge accounting and was revalued at fair value at the reporting period with unrealized gains and losses reflected in the Company's results of operations.

Fair Value Disclosures [Abstract]
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, and other current liabilities approximate their carrying amounts. Based on the borrowing rates currently available for bank loans with similar terms and average maturities, the fair value of finance leases at March 31, 2023 approximate their respective book values. The following table shows the carrying amounts and fair values of financial liabilities which are disclosed, but not measured, at fair value, including their levels in the fair value hierarchy: March 31, 2023 December 31, 2022 Carrying Amount Fair Value Carrying Amount Fair Value (in thousands) Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 ABL Facility $ 1,795,448 $ — $ 1,825,500 $ — $ 1,988,176 $ — $ 2,020,000 $ — 2025 Secured Notes 520,931 — 526,300 — 520,350 — 526,800 — 2028 Secured Notes 493,723 — 458,205 — 493,470 — 450,135 — Total $ 2,810,102 $ — $ 2,810,005 $ — $ 3,001,996 $ — $ 2,996,935 $ — As of March 31, 2023, the carrying values of the ABL Facility, the 2025 Secured Notes, and the 2028 Secured Notes included $30.1 million, $5.6 million, and $6.3 million, respectively, of unamortized debt issuance costs, which were presented as a direct reduction of the corresponding liability. As of December 31, 2022, the carrying value of the ABL Facility, the 2025 Secured Notes, and the 2028 Secured Notes included $31.8 million, $6.2 million, and $6.5 million, respectively, of unamortized debt issuance costs, which were presented as a direct reduction of the corresponding liability. The carrying value of the ABL Facility, excluding debt issuance costs, approximates fair value as the interest rates are variable and reflective of current market rates. The fair value of the 2025 Secured Notes and the 2028 Secured Notes is based on their last trading price at the end of each period obtained from a third party. The classification and the fair value of derivative assets and liabilities are disclosed in Note 12.

Stock-Based Compensation

Stock-Based Compensation	Mar. 31, 2023
Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation Stock-based compensation expense includes grants of stock options, time-based restricted stock units ("Time-Based RSUs") and performance-based restricted stock units ("Performance-Based RSUs," together with Time-Based RSUs, the "RSUs"). In addition, stock-based payments to non-executive directors includes grants of restricted stock awards ("RSAs"). Time-Based RSUs and RSAs are valued based on the intrinsic value of the difference between the exercise price, if any, of the award and the fair market value of WillScot Mobile Mini's Common Stock on the grant date. Performance-Based RSUs are valued based on a Monte Carlo simulation model to reflect the impact of the Performance-Based RSU's market condition. The probability of satisfying a market condition is considered in the estimation of the grant-date fair value for Performance-Based RSUs and the compensation cost is not reversed if the market condition is not achieved, provided the requisite service has been provided. Restricted Stock Awards The following table summarizes the Company's RSA activity for the three months ended March 31, 2023 and 2022 : 2023 2022 Number of Shares Weighted-Average Grant Date Fair Value Number of Shares Weighted-Average Grant Date Fair Value Outstanding at beginning of period 35,244 $ 37.17 36,176 $ 29.30 Outstanding at end of period 35,244 $ 37.17 36,176 $ 29.30 Compensation expense for RSAs recognized in SG&A on the condensed consolidated statements of operations was $0.3 million for each of the three months ended March 31, 2023 and 2022. At March 31, 2023, there was $0.2 million of unrecognized compensation cost related to RSAs that is expected to be recognized over the remaining weighted average vesting period of 0.2 years. Time-Based RSUs The following table summarizes the Company's Time-Based RSU activity for the three months ended March 31, 2023 and 2022 : 2023 2022 Number of Shares Weighted-Average Grant Date Fair Value Number of Shares Weighted-Average Grant Date Fair Value Outstanding at beginning of period 789,779 $ 26.16 997,451 $ 18.54 Granted 213,388 $ 50.74 357,639 $ 35.53 Forfeited (31,681) $ 33.67 (9,299) $ 27.20 Vested (281,153) $ 22.40 (420,184) $ 16.21 Outstanding at end of period 690,333 $ 34.95 925,607 $ 26.08 Compensation expense for Time-Based RSUs recognized in SG&A on the condensed consolidated statements of operations was $1.8 million and $2.2 million for the three months ended March 31, 2023 and 2022, respectively. At March 31, 2023, unrecognized compensation cost related to Time-Based RSUs totaled $21.6 million and is expected to be recognized over the remaining weighted average vesting period of 2.7 years.

At March 31, 2023, unrecognized compensation cost related to Performance-Based RSUs totaled $56.2 million and is expected to be recognized over the remaining vesting period of 2.1 years. Certain Performance-Based RSUs cliff vest based on achievement of the relative total stockholder return ("TSR") of the Company's Common Stock as compared to the TSR of the constituents in an index at the grant date over the performance period of three years. For 2023 grants, the TSR of the Company's Common Stock is compared to the TSR of the constituents in the S&P 400 Index. The target number of RSUs may be adjusted from 0% to 200% based on the TSR attainment levels defined by the Company's Compensation Committee. The 100% target payout is tied to performance at the 50% percentile, with a payout curve ranging from 0% (for performance less than the 25% percentile) to 200% (for performance above the 85% percentile).

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies The Company is involved in various lawsuits, claims and legal proceedings that arise in the ordinary course of business. The Company assesses these matters on a case-by-case basis as they arise and establishes reserves as required. As of March 31, 2023, with respect to these outstanding matters, the Company believes that the amount or range of reasonably possible loss will not, either individually or in the aggregate, have a material adverse effect on the consolidated financial position, results of operations, or cash flows. However, the outcome of such matters is inherently unpredictable and subject to significant uncertainties.

Segment Reporting

Segment Reporting	3 Months Ended
Segment Reporting	Mar. 31, 2023
Segment Reporting [Abstract]
Segment Reporting	Segment ReportingThe Company operates in two reportable segments as follows: Modular Solutions ("Modular") and Storage Solutions ("Storage"). 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. During the first quarter of 2023, the ground level office business within the Modular segment was transferred to the Storage segment, and associated revenues, expenses, and operating metrics were transferred to the Storage segment. All periods presented have been retrospectively revised to reflect this change within the Modular and Storage segments. For the three months ended March 31, 2022, this resulted in approximately $11.1 million of revenue and $6.3 million of gross profit being transferred from the Modular segment to the Storage segment. The Company defines EBITDA as net income (loss) plus interest (income) expense, income tax (benefit) expense, depreciation and amortization. The Company reflects further adjustments to EBITDA (“Adjusted EBITDA”) to exclude certain non-cash items and the effect of what the Company considers transactions or events not related to its core and ongoing business operations. In addition, the Chief Operating Decision Maker ("CODM") evaluates business segment performance utilizing Adjusted EBITDA as shown in the reconciliation of the Company’s consolidated income from continuing operations to Adjusted EBITDA below. Management believes that evaluating segment performance excluding such items is meaningful because it provides insight with respect to the intrinsic and ongoing operating results of the Company. The Company considers Adjusted EBITDA to be an important metric because it reflects the business performance of the segments, inclusive of indirect costs. The Company also regularly evaluates gross profit by segment to assist in the assessment of its operational performance. 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, 2023 and 2022, respectively.
