Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). The Company’s unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Unaudited Interim Financial Information The unaudited condensed consolidated balance sheet at December 31, 2023 was derived from audited financial statements but does not include all disclosures required by GAAP. The accompanying unaudited condensed consolidated financial statements as of September 28, 2024 and for the fiscal quarter and three fiscal quarters ended September 28, 2024 and September 30, 2023, respectively, have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial statements. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with Latham Group, Inc.’s audited consolidated financial statements and the notes thereto for the fiscal year ended December 31, 2023 included in the Company’s 2023 Annual Report on Form 10-K, filed with the SEC on March 13, 2024 (the “Annual Report”). In the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary for a fair statement of these condensed consolidated financial statements, have been included. The Company’s results of operations for the fiscal quarter and three fiscal quarters ended September 28, 2024 are not necessarily indicative of the results of operations that may be expected for the fiscal year ending December 31, 2024 or other interim periods thereof. Use of Estimates The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The Company bases its estimates on historical experience, known trends, and other market-specific relevant factors that it believes to be reasonable under the circumstances. Estimates are evaluated on an ongoing basis and revised as there are changes in circumstances, facts, and experience. Changes in estimates are recorded in the period in which they become known. Seasonality Although the Company generally has demand for its products throughout the fiscal year, its business is seasonal and weather is one of the principal external factors affecting the business. Historically, net sales and net income are highest (or net loss is lowest) during the second and third fiscal quarters, representing the peak months of swimming pool use, pool installation, and remodeling and repair activities. Severe weather may also affect net sales in all periods. Significant Accounting Policies Refer to the Annual Report for a discussion of the Company’s significant accounting policies, as updated below. Recently Issued Accounting Pronouncements The Company qualifies as “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 and has elected to “opt in” to the extended transition related to complying with new or revised accounting standards, which means that when a standard is issued or revised and it has different application dates for public and nonpublic companies, the Company will adopt the new or revised standard at the time nonpublic companies adopt the new or revised standard and will do so until such time that the Company either (i) irrevocably elects to “opt out” of such extended transition period or (ii) no longer qualifies as an emerging growth company. The Company may choose to early adopt any new or revised accounting standards whenever such early adoption is permitted for private companies. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”), which improves financial reporting by requiring disclosure of incremental segment information on an annual and interim basis for all public entities to enable investors to develop more decision-useful analysis. For all entities, ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The amendments should be applied retrospectively to all prior periods presented in the financial statements, with early adoption permitted. The Company is currently evaluating ASU 2023-07 and its potential impact on the notes to the condensed consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), in an effort to enhance the transparency and decision usefulness of income tax disclosures. For all entities, ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. The amendments should be applied prospectively with retrospective application permitted. Early adoption is also permitted. The Company is currently evaluating ASU 2023-09 and its potential impact on the notes to the condensed consolidated financial statements. In March 2024, the FASB issued ASU 2024-01, Compensation – Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards (“ASU 2024-01”), which improves financial reporting by providing clarity on when an entity should apply the scope guidance in paragraph 718-10-15-3. ASU 2024-01 is effective for public business entities for fiscal years beginning after December 15, 2024. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2025. The amendments should be applied retrospectively to all prior periods presented in the financial statements, with early adoption permitted. The Company is currently evaluating ASU 2024-01 and its potential impact on the condensed consolidated financial statements.

Business Combinations [Abstract]
Acquisitions	3. ACQUISITIONS Coverstar Central, LLC On August 2, 2024 (the “Acquisition Date”), Latham Pool Products acquired Coverstar Central, LLC (“Coverstar Central”) for total consideration of $71.0 million (the “Coverstar Central Acquisition”). The total consideration included $66.1 million in cash (including an estimated net working capital adjustment of $0.8 million) and a non-cash settlement of preexisting obligations of $4.9 million. Preexisting relationships are effectively settled since such a relationship becomes intercompany upon the acquisition and is eliminated in post-combination financial statements. The cash consideration was funded with cash on hand. The Company incurred $0.9 million in transaction costs. The results of Coverstar Central’s operations have been included in the condensed consolidated financial statements since that date. Coverstar Central is an automatic safety cover dealer based in the United States. The acquisition allows for vertical integration of the Company’s automatic safety cover product category. Additionally, the acquisition provides the Company with an increase in dealer and franchise relationships. The Company accounted for the Coverstar Central Acquisition using the acquisition method of accounting in accordance with FASB ASC 805, Business Combinations (“ASC 805”). This requires that the assets acquired and liabilities assumed be measured at fair value. Inventories were valued using the comparative sales method. Specific to intangible assets, backlog and customer relationships were valued using the multi-period excess earnings method. The Company recorded the assets acquired and liabilities assumed at their respective fair values as of the Acquisition Date. The fair value of assets acquired and liabilities assumed recorded in the condensed consolidated financial statements may be subject to adjustment pending completion of final evaluation. These fair value estimates will be reevaluated and adjusted, if needed, during the measurement period of up to one year from the Acquisition Date, and recorded as adjustments to goodwill. The following summarizes the preliminary allocation for the Company’s acquisition of Coverstar Central as of September 28, 2024: (in thousands) August 2, 2024 Total consideration $ 71,035 Allocation: Cash 2,084 Trade receivables 7,020 Inventories 4,293 Prepaid expenses and other current assets 53 Property and equipment 344 Intangible assets 38,220 Deferred tax assets 43 Total assets acquired, excluding goodwill 52,057 Accounts payable 131 Accrued expenses and other current liabilities 2,457 Total liabilities assumed 2,588 Total fair value of net assets acquired, excluding goodwill 49,469 Goodwill $ 21,566 The excess of the total consideration over the fair value of the identifiable assets acquired and the liabilities assumed in the acquisition was allocated to goodwill in the amount of $21.6 million. Goodwill resulting from the acquisition was attributable to vertical integration, the expanded market share and broader geographical footprint.

Fair Value Disclosures [Abstract]
Fair Value Measurements	4. FAIR VALUE MEASUREMENTS Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. To increase the comparability of fair value measures, the following hierarchy prioritizes the inputs to valuation methodologies used to measure fair value. Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 2 — Inputs, other than quoted prices in active markets, that are observable either directly or indirectly. Level 3 — Unobservable inputs that reflect the Company’s own assumptions incorporated into valuation techniques. These valuations require significant judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. When there is more than one input at different levels within the hierarchy, the fair value is determined based on the lowest level input that is significant to the fair value measurement in its entirety. Assessment of the significance of a particular input to the fair value measurement in its entirety requires substantial judgment and consideration of factors specific to the asset or liability. Level 3 inputs are inherently difficult to estimate. Changes to these inputs can have significant impact on fair value measurements. Assets and liabilities measured at fair value using Level 3 inputs are based on one or more of the following valuation techniques: market approach, income approach or cost approach. There were no transfers between fair value measurement levels during the three fiscal quarters ended September 28, 2024 or September 30, 2023. Assets and liabilities measured at fair value on a nonrecurring basis The Company’s non-financial assets such as goodwill, intangible assets, and property and equipment are measured at fair value upon acquisition and remeasured to fair value when an impairment charge is recognized. Such fair value measurements are based predominantly on Level 2 and Level 3 inputs. Fair value of financial instruments The Company considers the carrying amounts of cash, trade receivables, prepaid expenses and other current assets, accounts payable, and accrued expenses and other current liabilities to approximate fair value because of the short-term maturities of these instruments. Term loan The Company’s Term Loan (as defined below; see Note 7) is carried at amortized cost; however, the Company estimates the fair value of the Term Loan for disclosure purposes. The fair value of the Term Loan is determined using inputs based on observable market data of a non-public exchange, which are classified as Level 2 inputs. The following table sets forth the carrying amount and fair value of its Term Loan (in thousands): September 28, 2024 December 31, 2023 Carrying Estimated Carrying Estimated Value Fair Value Value Fair Value Term Loan $ 282,753 $ 271,444 $ 301,201 $ 289,153 Interest rate swap The Company estimates the fair value of interest rate swaps (see Note 7) on a fiscal quarterly basis using Level 2 inputs, including the forward SOFR curve. The fair value is estimated by comparing (i) the present value of all future monthly fixed rate payments versus (ii) the variable payments based on the forward SOFR curve. As of September 28, 2024 and December 31, 2023, the fair value of the Company’s interest rate swap was a liability of $2.1 million and $1.2 million, respectively, which were recorded within other long-term liabilities on the condensed consolidated balance sheets.

As of September 28, 2024, the Company was in compliance with all financial covenants under the Credit Agreement. Revolving Credit Facility The Revolving Credit Facility may be utilized to finance ongoing general corporate and working capital needs and permits Latham Pool Products to borrow loans in U.S. Dollars, Canadian Dollars, Euros and Australian Dollars. The Revolving Credit Facility matures on February 23, 2027. Loans outstanding under the Revolving Credit Facility denominated in U.S. Dollars and Canadian Dollars bear interest, at the borrower’s option, at a rate per annum based on Term SOFR or CDO (each, as defined in the Credit Agreement), as applicable, plus a margin of 3.50%, or at a rate per annum based on the Base Rate or the Canadian Prime Rate (each, as defined in the Credit Agreement), plus a margin of 2.50%. Loans outstanding under the Revolving Credit Facility denominated in Euros or Australian Dollars bear interest based on EURIBOR or the AUD Rate (each, as defined in the Credit Agreement), respectively, plus a margin of 3.50%. A commitment fee accrues on any unused portion of the commitments under the Revolving Credit Facility. The commitment fee is due and payable quarterly in arrears, and initially was 0.375% per annum and thereafter accrues at a rate per annum ranging from 0.25% to 0.50%, depending on the First Lien Net Leverage Ratio (as defined in the Credit Agreement). Borrowings under the Revolving Credit Facility are due at maturity. The Company incurred debt issuance costs of $0.8 million related to the Revolving Credit Facility. The debt issuance costs were recorded within other assets on the condensed consolidated balance sheet as of the applicable period and are being amortized over the life of the Revolving Credit Facility. The Company is required to meet certain financial covenants in connection with the Revolving Credit Facility, including maintaining specific liquidity measurements. There are also negative covenants, including certain restrictions on the Company’s and its subsidiaries’ ability to incur additional indebtedness, create liens, make investments, consolidate, or merge with other entities, enter into transactions with affiliates, make prepayments with respect to certain indebtedness, make dividend payments, loans, or advances to the Company, declare dividends and make restricted payments and other distributions. As of September 28, 2024, there were no outstanding borrowings on the Revolving Credit Facility and $75.0 million was available for future borrowing. Term Loan The Term Loan matures on February 23, 2029. The Term Loan bears interest, at the borrower’s option, at a rate per annum based on Term SOFR (as defined in the Credit Agreement), plus a margin ranging from 3.75% to 4.00%, depending on the First Lien Net Leverage Ratio, or based on the Base Rate (as defined in the Credit Agreement), plus a margin ranging from 2.75% to 3.00%, depending on the First Lien Net Leverage Ratio. The Term Loan is subject to scheduled quarterly amortization payments of $812,500, equal to 0.25% of the initial principal amount of the Term Loan. The Credit Agreement contains customary mandatory prepayment provisions for the Term Loan, including requirements to make mandatory prepayments with 50% of any excess cash flow and with 100% of the net cash proceeds from the incurrence of indebtedness not otherwise permitted to be incurred by the covenants, asset sales, and casualty and condemnation events, in each case, subject to customary exceptions. During the three fiscal quarters ended September 28, 2024, the Company made a payment of $18.0 million. Outstanding borrowings as of September 28, 2024 were $282.8 million, net of unamortized discount and debt issuance costs of $6.9 million. In connection with the Term Loan, the Company is subject to various negative, reporting, financial, and other covenants, including maintaining specific liquidity measurements. As of September 28, 2024, the unamortized debt issuance costs and discount on the Term Loan were $3.9 million and $3.1 million, respectively. The effective interest rate was 9.22% at September 28, 2024, including the impact of the Company’s interest rate swaps. Interest Rate Risk Interest rate risk associated with the Credit Agreement is mitigated partially through interest rate swaps. The Company executed an interest rate swap on April 30, 2020. The swap had an effective date of May 18, 2020 and a termination date of May 18, 2023. In February 2022, the Company amended its interest rate swap to change the index rate from LIBOR to SOFR in connection with the entry into the Credit Agreement. Under the terms of the amended swap, the Company fixed its SOFR borrowing rate at 0.496% on a notional amount of $200.0 million. The interest rate swap was not designated as a hedging instrument for accounting purposes (see Note 4). Additionally, the Company entered into an interest rate swap that was executed on March 10, 2023. The swap has an effective date of May 18, 2023 and a termination date of May 18, 2026. Under the terms of the swap, the Company fixed its SOFR borrowing rate at 4.3725% on a notional amount of $161.0 million. The interest rate swap is not designated as a hedging instrument for accounting purposes (see Note 4).

The obligations under the Credit Agreement are secured by substantially all of the Guarantors’ tangible and intangible assets, including their accounts receivables, equipment, intellectual property, inventory, cash and cash equivalents, deposit accounts, and security accounts. The Credit Agreement also restricts payments and other distributions unless certain conditions are met, which could restrict the Company’s ability to pay dividends.

Leases [Abstract]
Leases	9. LEASES For leases with initial terms greater than 12 months, the Company considers these right-of-use assets and records the related asset and obligation at the present value of lease payments over the term. For leases with initial terms equal to or less than 12 months, the Company does not consider them as right-of-use assets and instead considers them short-term lease costs that are recognized on a straight-line basis over the lease term. The Company’s leases may include escalation clauses, renewal options, and/or termination options that are factored into the Company’s determination of lease term and lease payments when it is reasonably certain the option will be exercised. The Company elected to take the practical expedient and not separate lease and non-lease components of contracts. The Company estimates an incremental borrowing rate to discount the lease payments based on information available at lease commencement because the implicit rate of the lease is generally not known. The Company leases manufacturing facilities, office space, land, and certain vehicles and equipment under operating leases. The Company also leases certain vehicles and equipment under finance leases. The Company determines if an arrangement is a lease at inception. A contract is or contains a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration.

STOCKHOLDERS’ EQUITY Repurchase Program On May 10, 2022, the Board of Directors of the Company approved a stock repurchase program (the “Repurchase Program”), which authorizes the Company to repurchase up to $100 million of the Company’s shares of common stock by May 2025. The Company may effect these repurchases in open market transactions, privately negotiated purchases, or other acquisitions. The Company is not obligated to repurchase any of its shares of its common stock under the Repurchase Program and the timing and amount of any repurchases will depend on market conditions, the Company’s stock price, alternative uses of capital, the terms of the Company’s debt instruments, and other factors. As of September 28, 2024, $77.0 million remained available for share repurchases pursuant to the Repurchase Program. The Company did not repurchase any shares of its common stock during the fiscal quarter ended September 28, 2024. The Company accounts for the excess of the repurchase price over the par value of shares acquired as a reduction to additional paid-in capital.

STOCK-BASED COMPENSATION On April 12, 2021, the Company’s stockholders approved the 2021 Omnibus Equity Incentive Plan (the “2021 Omnibus Equity Plan”), which became effective on April 22, 2021. The 2021 Omnibus Equity Plan provides for the issuance of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance stock units and other stock-based and cash-based awards. The maximum grant date fair value of cash and equity awards that may be awarded to a non-employee director under the 2021 Omnibus Equity Plan during any one fiscal year, together with any cash fees paid to such non-employee director during such fiscal year, is $750,000. On May 2, 2023, at the 2023 annual meeting of stockholders of the Company, the stockholders approved the first amendment (the “First Amendment”) to the 2021 Omnibus Equity Plan, which was previously approved by the Board of Directors of the Company. The First Amendment became effective upon stockholder approval, and included an increase by 8,000,000 shares of the share pool, i.e. the maximum number of shares of the Company’s common stock that may be issued pursuant to awards granted under the 2021 Omnibus Equity Plan. Except as amended by the First Amendment, the other terms of the 2021 Omnibus Equity Plan remain in full force and effect. Subsequent to the First Amendment, the maximum aggregate number of shares reserved for issuance under the 2021 Omnibus Equity Plan is 21,170,212 shares.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). The Company’s unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Unaudited Interim Financial Information The unaudited condensed consolidated balance sheet at December 31, 2023 was derived from audited financial statements but does not include all disclosures required by GAAP. The accompanying unaudited condensed consolidated financial statements as of September 28, 2024 and for the fiscal quarter and three fiscal quarters ended September 28, 2024 and September 30, 2023, respectively, have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial statements. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with Latham Group, Inc.’s audited consolidated financial statements and the notes thereto for the fiscal year ended December 31, 2023 included in the Company’s 2023 Annual Report on Form 10-K, filed with the SEC on March 13, 2024 (the “Annual Report”). In the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary for a fair statement of these condensed consolidated financial statements, have been included. The Company’s results of operations for the fiscal quarter and three fiscal quarters ended September 28, 2024 are not necessarily indicative of the results of operations that may be expected for the fiscal year ending December 31, 2024 or other interim periods thereof.
Use of Estimates	Use of Estimates The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The Company bases its estimates on historical experience, known trends, and other market-specific relevant factors that it believes to be reasonable under the circumstances. Estimates are evaluated on an ongoing basis and revised as there are changes in circumstances, facts, and experience. Changes in estimates are recorded in the period in which they become known.
Seasonality	Seasonality Although the Company generally has demand for its products throughout the fiscal year, its business is seasonal and weather is one of the principal external factors affecting the business. Historically, net sales and net income are highest (or net loss is lowest) during the second and third fiscal quarters, representing the peak months of swimming pool use, pool installation, and remodeling and repair activities. Severe weather may also affect net sales in all periods.
Significant Accounting Policies	Significant Accounting Policies Refer to the Annual Report for a discussion of the Company’s significant accounting policies, as updated below.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements The Company qualifies as “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 and has elected to “opt in” to the extended transition related to complying with new or revised accounting standards, which means that when a standard is issued or revised and it has different application dates for public and nonpublic companies, the Company will adopt the new or revised standard at the time nonpublic companies adopt the new or revised standard and will do so until such time that the Company either (i) irrevocably elects to “opt out” of such extended transition period or (ii) no longer qualifies as an emerging growth company. The Company may choose to early adopt any new or revised accounting standards whenever such early adoption is permitted for private companies. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”), which improves financial reporting by requiring disclosure of incremental segment information on an annual and interim basis for all public entities to enable investors to develop more decision-useful analysis. For all entities, ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The amendments should be applied retrospectively to all prior periods presented in the financial statements, with early adoption permitted. The Company is currently evaluating ASU 2023-07 and its potential impact on the notes to the condensed consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), in an effort to enhance the transparency and decision usefulness of income tax disclosures. For all entities, ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. The amendments should be applied prospectively with retrospective application permitted. Early adoption is also permitted. The Company is currently evaluating ASU 2023-09 and its potential impact on the notes to the condensed consolidated financial statements. In March 2024, the FASB issued ASU 2024-01, Compensation – Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards (“ASU 2024-01”), which improves financial reporting by providing clarity on when an entity should apply the scope guidance in paragraph 718-10-15-3. ASU 2024-01 is effective for public business entities for fiscal years beginning after December 15, 2024. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2025. The amendments should be applied retrospectively to all prior periods presented in the financial statements, with early adoption permitted. The Company is currently evaluating ASU 2024-01 and its potential impact on the condensed consolidated financial statements.
