Basis of Presentation [Abstract]
Basis of Presentation	Note 1. Basis of Presentation Lumber Liquidators Holdings, Inc. and its direct and indirect subsidiaries (collectively and, where applicable, individually, “LL Flooring” or the “Company”) engage in business as a multi-channel specialty retailer of hard-surface flooring, and hard-surface flooring enhancements and accessories, operating as a single operating segment. The Company offers an extensive assortment of exotic and domestic hardwood species, engineered hardwood, laminate, resilient vinyl, water-resistant vinyl plank and porcelain tile flooring direct to the consumer. The Company features renewable flooring products, bamboo and cork, and provides a wide selection of flooring enhancements and accessories, including moldings, noise-reducing underlayment, adhesives and flooring tools. The Company also provides in-home delivery and installation services to its customers. The Company primarily sells to homeowners or to contractors on behalf of homeowners through a network of store locations in metropolitan areas. As of September 30, 2021, the Company’s network of 422 stores spanned 47 states in the United States (“U.S.”). In addition to the store locations, the Company’s products may be ordered, and customer questions/concerns addressed, through both its customer relationship center in Richmond, Virginia and its digital platform, LLFlooring.com The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q for interim financial reporting pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of management, all adjustments (consisting of normal and recurring adjustments except those otherwise described herein) considered necessary for a fair presentation have been included in the accompanying condensed consolidated financial statements. However, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements. Therefore, the interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s annual report filed on Form 10-K for the year ended December 31, 2020. The condensed consolidated financial statements of the Company include the accounts of its wholly owned subsidiaries. All intercompany transactions have been eliminated in consolidation. Results of operations for the three and nine months ended September 30, 2021 are not necessarily indicative of future results to be expected for the full year due to a number of factors, including supply chain, seasonality, tariffs, and general economic conditions, as well as the uncertainty and ongoing impact of the COVID-19 pandemic that may impact supply chain and/or sales for the remainder of fiscal 2021.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Fair Value of Financial Instruments ​ The carrying amounts of financial instruments such as cash and cash equivalents, accounts payable and other liabilities approximates fair value because of the short-term nature of these items. ​ Merchandise Inventories ​ The Company values merchandise inventories at the lower of cost or net realizable value. The method by which amounts are removed from inventory is weighted average cost. All of the hardwood flooring purchased from vendors is either prefinished or unfinished, and in immediate saleable form. The Company relies on a select group of international and domestic suppliers to provide imported flooring products that meet the Company’s specifications. The Company is subject to risks associated with obtaining products from abroad, including disruptions or delays in production, shipments, supply chain, delivery or processing, including due to the COVID-19 pandemic. The Company continues to execute contingency plans to minimize ongoing disruptions to supply chain, domestic distribution centers and store operations. Included in merchandise inventories are tariff-related costs, including Section 301 tariffs on certain products imported from China in recent years. A subset of these imports for certain click vinyl and other engineered products (the “Subset Products”) received an exemption that was made retroactive to the beginning of the Section 301 Tariffs for a period of time. The Company has deployed strategies to mitigate tariffs and improve gross margin, primarily through adjusting its pricing and promotion strategies and alternative country sourcing. The Company continues to monitor market pricing and promotional strategies to inform and guide its decisions. . ​ ​ ​ ​ ​ ​ ​ ​ Section 301 tariff ​ Corresponding approximate Event Timing level on imports Tariff level on percentage of Company's ​ ​ from China Subset Products merchandise subject to tariff Imposition of Tariffs September 2018 10% 10% then 0% 1 48% Increase in Tariffs June 2019 25% 25% then 0% 1 44% Retroactive Exemption on Subset Products 1 November 2019 25% 0% 10% Exemption Not Renewed and Tariffs Re-imposed on Subset Products August 2020 25% 25% 32% ​ September 30, 2021 25% 25% 22% 1 On November 7, 2019, the U.S. Trade Representative granted a retroactive exclusion to September 2018 on Subset Products as defined in the Section 301 Tariffs section above bringing the rate to 0%. ​ Recognition of Net Sales The Company generates revenues primarily by retailing merchandise in the form of hard-surface and porcelain flooring and accessories. Additionally, the Company expands its revenues by offering services to deliver and/or install this merchandise for its customers; it considers these services to be separate performance obligations. The separate performance obligations are detailed on the customer’s invoice(s) and the customer often purchases flooring merchandise without purchasing installation or delivery services. Sales occur through a network of 422 stores, which spanned 47 states in the U.S. at September 30, 2021. In addition, both the merchandise and services can be ordered through a call center and from the Company’s digital platform, LLFlooring.com Revenue is based on consideration specified in a contract with a customer and excludes any sales incentives from vendors and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product to a customer or performing services for a customer. Revenues from installation and freight services are recognized when the delivery is made or the installation is complete, which approximates the recognition of revenue over time due to the short duration of service provided. The price of the Company’s merchandise and services is specified in the respective contract and detailed on the invoice agreed to with the customer including any discounts. The Company generally requires customers to pay a deposit, equal to approximately half of the retail sales value, when ordering merchandise not regularly carried in a given location or not currently in stock. In addition, the Company generally does not extend credit to its customers with payment due in full at the time the customer takes possession of merchandise or when the service is provided. Customer payments and deposits received in advance of the customer taking possession of the merchandise or receiving the services are recorded as deferred revenues in the accompanying condensed consolidated balance sheet caption “Customer Deposits and Store Credits.” The following table shows the activity in this account for the periods noted: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended ​ ​ September 30, ​ September 30, ​ 2021 2020 2021 2020 Customer Deposits and Store Credits, Beginning Balance ​ $ (67,731) ​ $ (55,492) ​ $ (61,389) ​ $ (41,571) New Deposits ​ (304,604) ​ (324,726) ​ (935,576) ​ (870,052) Recognition of Revenue ​ 282,229 ​ 295,833 ​ 867,063 ​ 793,491 Sales Tax included in Customer Deposits ​ 16,936 ​ 18,389 ​ 52,708 ​ 49,932 Other ​ 2,949 ​ 2,260 ​ 6,973 ​ 4,464 Customer Deposits and Store Credits, Ending Balance ​ $ (70,221) ​ $ (63,736) ​ $ (70,221) ​ $ (63,736) ​ Subject to limitations under the Company’s policy, return of unopened merchandise is accepted for 90 days, subject to the discretion of the store manager. The amount of revenue recognized for flooring merchandise is adjusted for expected returns, which are estimated based on the Company’s historical data, current sales levels, and forecasted economic trends. The Company uses the expected value method to estimate returns because it has a large number of contracts with similar characteristics. The Company reduces revenue by the amount of expected returns and records it within “Other Current Liabilities” on the condensed consolidated balance sheet. The Company continues to estimate the amount of returns based on historical data. In addition, the Company recognizes a related asset for the right to recover returned merchandise and records it in the “Other Current Assets” caption of the accompanying condensed consolidated balance sheet. This amount was In total, the Company offers hundreds of different flooring products; however, no single flooring product represented a significant portion of its sales mix. By major product category, the Company’s sales mix was as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended September 30, ​ Nine Months Ended September 30, ​ ​ 2021 2020 2021 ​ 2020 ​ Manufactured Products 1 ​ $ 129,543 ​ 46 % $ 135,119 ​ 46 % $ 401,373 ​ 46 % $ 366,632 ​ 46 % Solid and Engineered Hardwood ​ ​ 69,090 24 % ​ 80,643 27 % ​ 220,887 26 % ​ 219,444 28 % Moldings and Accessories and Other ​ 42,169 15 % 45,247 15 % 128,128 15 % 123,769 16 % Installation and Delivery Services ​ 41,427 15 % 34,824 12 % 116,675 13 % 83,646 10 % Total ​ $ 282,229 100 % $ 295,833 100 % $ 867,063 100 % $ 793,491 100 % 1 Cost of Sales ​ Cost of sales includes the cost of products sold, including tariffs, the cost of installation services, and transportation costs from vendors to the Company’s distribution centers or store locations. It also includes transportation costs from distribution centers to store locations, transportation costs for the delivery of products from store locations to customers, certain costs of quality control procedures, warranty and customer satisfaction costs, inventory adjustments including obsolescence and shrinkage, and costs to produce and ship samples, which are net of vendor allowances. The Company offers a range of limited warranties for the durability of the finish on its prefinished products to its services provided. These limited warranties range from one , with lifetime warranties for certain of the Company’s products. Warranty reserves are based primarily on claims experience, sales history and other considerations, including payments made to satisfy customers for claims not directly related to the warranty on the Company’s products. This warranty reserve was Vendor allowances mostly consist of volume rebates and are accrued as earned, with those allowances received as a result of attaining certain purchase levels accrued over the incentive period based on estimates of purchases. Volume rebates earned are initially recorded as a reduction in merchandise inventories and a subsequent reduction in cost of sales when the related product is sold. Reimbursement received for the cost of producing samples is recorded as an offset against cost of sales.

The performance-based RSAs in both years were awarded to certain members of senior management in connection with the achievement of specific key financial metrics that will be measured over separate respective three-year periods and which will vest at the end of each respective three-year period if the respective performance conditions are met. In addition, the number of 2020 performance-based awards that will ultimately vest is also contingent upon the results of a relative total shareholder return multiple by the end of year three. The Company assesses the probability of achieving these metrics on a quarterly basis.

Credit Agreement
Credit Agreement	Note 5. Credit Agreement The Company has a credit agreement (the “Credit Agreement”) with Bank of America, N.A. and Wells Fargo Bank, N.A. (the “Lenders”). On April 30, 2021, the Company entered into a Second Amendment to the Credit Agreement (the “Second Amendment”) with the Lenders. The execution of the Second Amendment, among other things, terminated the FILO Term Loans and converted those commitments to the Revolving Credit Facility. The total size of the Credit Agreement remained at $200 million, and the Company has an option to the increase the Revolving Credit Facility to a maximum total amount of $250 million. The maturity date of the Credit Agreement was extended to April 30, 2026 . ​ The Revolving Credit Facility is secured by security interests in the Collateral (as defined in the Credit Agreement), which includes substantially all assets of the Company including, among other things, the Company’s inventory and credit card receivables, and the Company’s East Coast distribution center located in Sandston, Virginia. Under the terms of the Credit Agreement, the Company has the ability to release the East Coast distribution center from the Collateral under certain conditions. ​ The Second Amendment decreased the margin for LIBOR Rate Loans (as defined in the Second Amendment) to a range of 1.25% to 1.75% over the applicable LIBOR Rate with respect to revolving loans (as defined in the Second Amendment) depending on the Company’s’ average daily excess borrowing availability, a decrease of from rates prior to the Second Amendment. As previously stated, the FILO Term Loans were terminated by this Second Amendment. The amendment decreased the LIBOR Rate Floor from 1.00% to 0.25 %. The Second Amendment also decreased the unused commitment fee of 0.50% per annum to 0.25 % per annum on the average daily unused amount of the Revolving Credit Facility during the most recently completed calendar quarter. As of September 30, 2021, had the Company re-borrowed, the Revolving Credit Facility would have carried an interest rate subject to the terms stated directly above. ​ The Credit Agreement contains a fixed charge coverage ratio covenant that becomes effective only when specified availability under the Revolving Credit Facility falls below the greater of $17.5 million or 10% of the Combined Loan Cap (as defined in the Credit Agreement). ​ Except as set forth in the Second Amendment, all other terms and conditions of the Credit Agreement remain in place. ​ The Company repaid all $101.0 million of borrowings during the second quarter of 2021. As of September 30, 2021, there was no amount outstanding under the Revolving Credit Facility. The Company had $3.0 million in letters of credit which reduces its availability. As of September 30, 2021, there was $128.0 million of availability under the Revolving Credit Facility. ​

Income Taxes [Abstract]
Income Taxes	Note 6. Income Taxes The Company calculates its quarterly tax provision pursuant to the guidelines in Accounting Standards Codification ("ASC") 740-270 "Income Taxes." Generally, ASC 740-270 requires companies to estimate the annual effective tax rate for current year ordinary income. The estimated annual effective tax rate represents the best estimate of the tax provision in relation to the best estimate of pre-tax ordinary income or loss. The estimated annual effective tax rate is then applied to year-to-date ordinary income or loss to calculate the year-to-date interim tax provision and is adjusted for discrete items that occur within the period. This process has been employed in 2021. Due to disruption related to the COVID-19 pandemic in 2020, the Company applied For the three months ended September 30, 2021, the Company recognized income tax expense of $3.2 million, which represented an effective tax rate of 27.0%. For the three months ended September 30, 2020, the Company recognized income tax expense of $7.0 million, which represented an effective tax rate of 31.0%. For the nine months ended September 30, 2021, the Company recognized income tax expense of . The variability of the tax rate between the two periods is due to the use of the effective tax rate method in 2021 compared to discrete provision in 2020, including the favorable impact of the Coronavirus Aid, Relief, and Economic Security Act (CARES Act). The Company has a valuation allowance recorded against certain of its net deferred tax assets of $5.6 million as of September 30, 2021 because the jurisdiction and nature of the assets makes realization of these deferred tax assets uncertain. The Company intends to maintain this valuation allowance on its deferred tax assets until there is sufficient evidence to support the realizability of those deferred tax assets or time lapses without opportunity to realize those assets.

Employment Cases Mason Lawsuit ​ In August 2017, Ashleigh Mason, Dan Morse, Ryan Carroll and Osagie Ehigie filed a purported class action lawsuit in the United States District Court for the Eastern District of New York on behalf of all current and former store managers, store managers in training, and similarly situated current and former employees (collectively, the “Mason Putative Class Employees”) alleging that the Company violated the Fair Labor Standards Act (“FLSA”) and New York Labor Law (“NYLL”) by classifying the Mason Putative Class Employees as exempt. The alleged violations include failure to pay for overtime work. The plaintiffs sought certification of the Mason Putative Class Employees for (i) a collective action covering the period beginning (ii) a class action covering the period beginning six years prior to the filing of the complaint (plus a tolling period) through the disposition of this action for members of the Mason Putative Class Employees who currently are or were employed in New York in connection with NYLL. The plaintiffs did not quantify any alleged damages but, in addition to attorneys’ fees and costs, the plaintiffs seek class certification, unspecified amounts for unpaid wages and overtime wages, liquidated and/or punitive damages, declaratory relief, restitution, statutory penalties, injunctive relief and other damages. ​ In November 2018, the plaintiffs filed a motion requesting conditional certification for all store managers and store managers in training who worked within the federal statute of limitations period. In May 2019, the magistrate judge granted plaintiffs’ motion for conditional certification. On January 6, 2021, the magistrate judge ruled in favor of a motion by the Company to exclude from the Mason Putative Class the claims of In April 2021, the Company entered into a Memorandum of Understanding (“Mason MOU”) with counsel for the lead plaintiffs in the Mason matter. Under the terms of the Mason MOU, the Company will pay up to million to settle the claims asserted in the Mason matter on behalf of all Mason Putative Class Employees who (i) opted-in to the collective action (“Collective Members”) and (ii) are currently or were employed in New York and did not previously file an opt-in notice to participate in the collective action (the “New York Non Opt-Ins”). The New York Non Opt-Ins will have an opportunity to file an opt-in notice to participate in the settlement. To the extent that a New York Non Opt-In does not subsequently file such a notice, then the amount apportioned to that claim shall revert to the Company. In addition, any checks issued to the Collective Members and the New York Non Opt-Ins which are not cashed within one hundred eighty days will revert to the Company. The Mason MOU is subject to certain contingencies, including court approval of the definitive settlement agreement. There can be no assurance that a settlement will be approved or as to the ultimate outcome of the litigation. If a final, court approved settlement is not reached, the Company will defend the matter vigorously and believes there are meritorious defenses and legal standards that must be met for success on the merits. If the parties are unable to finalize the settlement, the Mason matter could have a material adverse effect on the Company’s financial condition and results of operations. As a result of these developments, the Company determined that a probable loss has been incurred and has accrued within SG&A a million liability during the first quarter of 2021. As of September 30, 2021, the remaining accrual related to this matter is Savidis Lawsuit ​ On April 9, 2020, Lumber Liquidators was served with a lawsuit filed by Tanya Savidis, on behalf of herself and all others similarly situated (collectively, the “Savidis Plaintiffs”). Ms. Savidis filed a purported class action lawsuit in the Superior Court of California, County of Alameda on March 6, 2020, on behalf of all current and former Lumber Liquidators employees employed as non-exempt employees. The complaint alleges violation of the California Labor Code including, among other items, failure to pay minimum wages and overtime wages, failure to provide meal periods, failure to permit rest breaks, failure to reimburse business expenses, failure to provide accurate wage statements, failure to pay all wages due upon separation within the required time, and engaging in unfair business practices (the “Savidis matter”). On or about May 22, 2020, the Savidis Plaintiffs provided notice to the California Department of Industrial Relations requesting they be permitted to seek penalties under the California Private Attorney General Act for the same substantive alleged violations asserted in the Complaint. The Savidis Plaintiffs seek certification of a class action covering the prior ​ In December 2020, the Company began contacting individuals who constitute the Savidis Plaintiffs and offered individual settlements in satisfaction of their claims. In April 2021, the Company entered into a Memorandum of Understanding (“Savidis MOU”) with counsel for the lead plaintiffs in the Savidis matter. Under the terms of the Savidis MOU, the Company will pay individuals who accepted the Company’s prior settlement offer. The Company accrued an additional thousand related to this matter in the first quarter 2021. The Savidis MOU is subject to certain contingencies, including court approval of the definitive settlement agreement. There can be no assurance that a settlement will be approved or as to the ultimate outcome of the litigation. If a final, court approved settlement is not reached, the Company will defend the matter vigorously and believes there are meritorious defenses and legal standards that must be met for success on the merits. If the parties are unable to finalize the settlement, the Savidis matter could have a material adverse effect on the Company’s financial condition and results of operations. ​ Visnack Lawsuit ​ On June 29, 2020, Michael Visnack, on behalf of himself and all others similarly situated (collectively, the “Visnack Plaintiffs”) filed a purported class action lawsuit in the Superior Court of California, County of San Diego, on behalf of all current and former store managers, and others similarly situated. The Complaint alleges violation of the California Labor Code including, among other items, failure to pay wages and overtime, wage statement violations, meal and rest break violations, unpaid reimbursements and waiting time, and engaging in unfair business practices (the “Visnack matter”). The Visnack Plaintiffs seek certification of a class period beginning September 20, 2019, through the date of Notice of Class Certification, if granted. The Visnack Plaintiffs did not quantify any alleged damages but, in addition to attorneys’ fees and costs, they seek unspecified amounts for each of the causes of action such as unpaid wages and overtime wages, failure to provide meal periods and rest breaks, payroll record and wage statement violations, failure to reimburse expenses and waiting time, liquidated and/or punitive damages, declaratory relief, restitution, statutory penalties, injunctive relief and other damages. On December 14, 2020, the court ruled in favor of a motion by the Company to compel arbitration for Michael Visnack under the existing agreement between the Company and Mr. Visnack. The court declined to outright dismiss the putative class claims but stayed the putative class claims and Private Attorneys General Act claims pending arbitration. The court denied plaintiff’s request to conduct discovery. In the first quarter of 2021, the Company received notice that Mr. Visnack has filed an arbitration claim, which the Company intends to defend. Mr. Visnack is a Collective Member of the Mason Putative Class and will have the opportunity to decide whether to participate in the Mason settlement and release his claims against the Company, in which case he would be removed as the lead Plaintiff in the Visnack matter. ​ The Company is evaluating the Visnack Putative Class Employees' claims and intends to defend itself vigorously in this matter. Given the uncertainty of litigation, the preliminary stage of the case and the legal standards that must be met for, among other things, class certification and success on the merits, the Company cannot estimate the reasonably possible loss or range of loss, if any, that may result from this action and therefore no accrual has been made related to this. Any such losses could, potentially, have a material adverse effect, individually or collectively, on the Company’s results of operations, financial condition and liquidity. Kramer lawsuit ​ In November 2017, Robert J. Kramer, on behalf of himself and all others similarly situated (collectively, the “Kramer Plaintiffs”) filed a purported class action lawsuit in the Superior Court of California, County of Sacramento on behalf of all current and former store managers, all others with similar job functions and/or titles and all current and former employees classified as non-exempt or incorrectly classified as exempt and who worked for the Company in the State of California alleging violation of the California Labor Code including, among other items, failure to pay wages and overtime and engaging in unfair business practices (the “Kramer matter”). The Company reached settlement for this matter for Antidumping and Countervailing Duties Investigation In October 2010, a conglomeration of domestic manufacturers of multilayered wood flooring (“Petitioners”) filed a petition seeking the imposition of antidumping (“AD”) and countervailing duties (“CVD”) with the United States Department of Commerce (“DOC”) and the United States International Trade Commission (“ITC”) against imports of multilayered wood flooring from China. This ruling applies to companies importing multilayered wood flooring from Chinese suppliers subject to the AD and CVD orders. The Company’s multilayered wood flooring imports from China accounted for approximately 4% and 6% of its flooring purchases in 2020 and 2019, respectively. ​ As part of its processes in these proceedings, the DOC conducts annual reviews of the AD and CVD rates. In such cases, the DOC will issue preliminary rates that are not binding and are subject to comment by interested parties. After consideration of the comments received, the DOC will issue final rates for the applicable period, which may lag by a year or more. At the time of import, the Company makes deposits at the then prevailing rate, even while the annual review is in process. When rates are declared final by the DOC, the Company accrues a receivable or payable depending on where that final rate compares to the deposits it has made. The Company and/or the domestic manufacturers can appeal the final rate for any period and can place a hold on final settlement by U.S. Customs and Border Protection while the appeals are pending. ​ The Company as well as other involved parties have appealed many of the final rate determinations. Certain of those appeals are pending and, at times, have resulted in delays in settling the shortfalls and refunds shown in the table below. Because of the length of time for finalization of rates as well as appeals, any subsequent adjustment of AD and CVD rates typically flows through a period different from those in which the inventory was originally purchased and/or sold. ​ Results by period for the Company are shown below. The column labeled ‘September 30, 2021 Receivable/Liability Balance’ represents the amount the Company would receive or pay (net of any collections or payments) as the result of subsequent adjustment to rates whether due to finalization by the DOC or because of action of a court based on appeals by various parties. It does not include any initial amounts paid for AD or CVD in the current period at the in-effect rate at that time. The Company recorded net interest income related to antidumping of $1.8 million for the nine months ended September 30, 2021, with the amount included in other expense on the condensed consolidated statements of operations. The estimated associated interest payable and receivable for each period is not included in the table below but is included in the same financial statement line item on the Company’s condensed consolidated balance sheet as the associated liability and receivable balance for each period. ​ ​ ​ ​ ​ ​ Review Rates at which September 30, 2021 Period Period Covered Company Final Rate Receivable/Liability ​ ​ Deposited ​ Balance Antidumping 1 May 2011 through 6.78% and 3.3% 0.73% 1 $1.3 million ​ November 2012 ​ ​ receivable 1 2 December 2012 through 3.30% 3.92% 2 $0.2 million ​ November 2013 ​ ​ liability 2 3 December 2013 through 3.3% and 5.92% 0.0% 3 $1.8 million ​ November 2014 ​ ​ receivable 3 4 December 2014 through 5.92% and 13.74% 0.0% Settled ​ November 2015 ​ ​ ​ 5 December 2015 through 5.92%. 13.74%. and 17.37% 0.0% Settled ​ November 2016 ​ ​ ​ 6 December 2016 through 17.37% and 0.0% 42.57% and 0.0% 4 $0.5 million receivable ​ November 2017 ​ ​ $1.5 million liability 4 7 December 2017 through 0.0% 0.0% 5 NA ​ November 2018 ​ ​ ​ 8 December 2018 through 0.0% 0.0 % 6 NA ​ November 2019 ​ ​ ​ ​ ​ ​ Included on the Condensed Consolidated Balance Sheet in $2.3 million ​ ​ ​ Included on the Condensed Consolidated Balance Sheet in $1.3 million ​ ​ ​ Included on the Condensed Consolidated Balance Sheet in Other Current Liabilities $0.2 million ​ ​ ​ Included on the Condensed Consolidated Balance Sheet in $1.5 million Countervailing 1&2 April 2011 through 1.50% 0.83% / 0.99% $0.2 million ​ December 2012 ​ ​ receivable 3 January 2013 through 1.50% 1.38% $0.05 million 4 January 2014 through 1.50% and 0.83% 1.06% $0.02 million 5 January 2015 through 0.83% and 0.99% Final at 0.11% and 0.85% 7 $0.07 million 7 6 January 2016 through 0.99% and 1.38% Final at 3.10% and 2.96% $0.04 million 8 7 January 2017 through 1.38% and 1.06% 20.75% 9 $1.7 million 9 8 January 2018 through 1.06% 5.81% 10 NA ​ ​ ​ Included on the Condensed Consolidated Balance Sheet in $0.07 million ​ ​ ​ Included on the Condensed Consolidated Balance Sheet in $0.3 million ​ ​ ​ Included on the Condensed Consolidated Balance Sheet in Other Current Liabilities $0.04 million ​ ​ ​ Included on the Condensed Consolidated Balance Sheet in Other Long-Term Liabilities $1.7 million 1 In the second quarter of 2018, the Court of International Trade (“CIT”) sustained the DOC’s recommendation to reduce the rate for the first annual review period to 0.73% (from 5.92% ). As a result, the Company reversed its $0.8 million liability and recorded a $1.3 million receivable with a corresponding reduction of cost of sales during the year ended December 31, 2018 . ​ 2 In the second quarter of 2020, the CIT received a recommendation from the DOC to reduce the rate for the second annual review period to 3.92% (from 13.74%) . The recommendation was accepted by the CIT in the fourth quarter of 2020, and the Company reversed $3.9 million of its $4.1 million liability, with a corresponding reduction of cost of sales. ​ 3 In the third quarter of 2020, the CIT received a recommendation from the DOC to reduce the rate for the third annual review period to 0.0% from 17.37% . The recommendation was accepted by the CIT in the first quarter of 2021, and the Company reversed the entire $4.7 million liability, with a corresponding reduction of cost of sales, and recorded a $1.8 million receivable and favorable adjustment to cost of sales for deposits made at previous preliminary rates. ​ 4 In the third quarter of 2019, the DOC issued the final rates for the sixth annual review period at 42.57% and 0% depending on the vendor. As a result, the Company recorded a liability of $0.8 million with a corresponding reduction of cost of sales during the year ended December 31, 2019. The Company received payments during 2019 for its vendor with a final rate of 0.0% and the remaining balance of $0.5 million as of June 30, 2021 was included in other current assets on the condensed consolidated balance sheet. The vendors with a final rate of 42.57% are under appeal and the balance of $1.5 million as of September 30, 2021 was included in other long-term liabilities on the condensed consolidated balance sheet. ​ 5 In the first quarter of 2020, the DOC issued a preliminary rate of 0.0% for the seventh annual review period. ​ 6 In April 2021, the DOC issued a preliminary rate of 0.0% for the eighth annual review period. This rate was finalized at 0.0% in October 2021. ​ 7 In the second quarter of 2018, the DOC issued the final rates for the fifth annual review period at 0.11% and 0.85% depending on the vendor. As a result, in the second quarter of 2018, the Company recorded a receivable of $0.07 million for deposits made at previous preliminary rates, with a corresponding reduction of cost of sales. ​ 8 In the third quarter of 2019, the DOC issued the final rates for the sixth annual review period at 3.1% and 2.96% depending on the vendor. As a result, the Company recorded a liability of $0.4 million with a corresponding reduction of cost of sales during the year ended December 31, 2019 . The remaining balance, after payments, was approximately $40 thousand as of September 30, 2021. ​ 9 In the fourth quarter of 2020, the DOC issued the final rate 20.75% for the seventh annual review period. As a result, the Company recorded a liability of $1.7 million with a corresponding increase to cost of sales during the year ended December 31, 2020. The Company has appealed this final rate during the first quarter of 2021. ​ 10 In October 2021, the DOC issued the final rate of 5.81% for the eighth annual review period . As a result, in October 2021 the Company recorded a $0.3 million liability with a corresponding increase in cost of sales. ​ Litigation Relating to Bamboo Flooring ​ Dana Gold filed a purported class action lawsuit in the United States District Court for the Northern District of California alleging that the Morning Star bamboo flooring that the Company sells was defective (the “Gold Litigation”). In the third quarter of 2019, the parties finalized a settlement agreement that is consistent with the terms of the Memorandum of Understanding previously disclosed by the Company, to resolve the Gold Litigation on a nationwide basis. Under the terms of the settlement agreement, the Company contributed Notice has been disseminated to class members by the settlement administrator, and final approval was granted by the court on October 22, 2020. The Company has notified its insurance carriers and continues to pursue coverage, but the insurers to date have denied coverage. As the insurance claim is still pending, the Company has not recognized any insurance recovery related to the Gold Litigation. The Company recognized a charge to earnings of $28 million within selling, general and administrative expense during the fourth quarter of 2018 as its loss became probable and estimable. During the third quarter of 2020, the Company recognized an additional charge to earnings for in-store vouchers of million within selling, general and administrative expense as the Company became aware that a threshold in the settlement agreement was met. The Company paid the remaining million of the Gold Cash Payment in the fourth quarter of 2020. The vouchers were issued in the middle of the third quarter of 2021. As of September 30, 2021, the remaining accrual related to these matters was Settlements” on its condensed consolidated balance sheet. ​ In addition, there are a number of individual claims and lawsuits alleging damages involving Strand Bamboo Product (the “Bamboo Flooring Litigation”). While the Company believes that a loss associated with the Bamboo Flooring Litigation is reasonably possible, the Company is unable to reasonably estimate the amount or range of possible loss. Any such losses could, potentially, have a material adverse effect, individually or collectively, on the Company’s results of operations, financial condition and liquidity. The Company disputes the claims in the Bamboo Flooring Litigation and intends to defend such matters vigorously. ​ On September 9, 2021, Larry and Kathy Fluharty filed a purported class action lawsuit in the United States District Court for the Eastern District of Arkansas alleging substantially the same allegations as the Gold Litigation, for a class period beginning March 16, 2019 to present (the “Fluharty Litigation”). The Company is evaluating the Fluharty Litigation and is unable to determine if a loss is reasonably possible or to estimate the amount or range of possible loss, if any. The Company disputes the claims in the Fluharty Litigation and intends to defend the matter vigorously. ​ Litigation Related to Formaldehyde-Abrasion MDLs Beginning in 2015, numerous purported class action cases were filed in various United States federal district courts and state courts involving claims of excessive formaldehyde emissions and product claims about durability and abrasion from the Company’s Chinese-manufactured laminate flooring products. The United States Judicial Panel on Multidistrict Litigation transferred and consolidated the federal cases to the United States District Court for the Eastern District of Virginia (the “Virginia Court”) as two cases: Lumber Liquidators Chinese-Manufactured Flooring Products Marketing, Sales, Practices and Products Liability Litigation (the “Formaldehyde MDL”) and Lumber Liquidators Chinese-Manufactured Laminate Flooring Durability Marketing and Sales Practices Litigation (the “Abrasion MDL”). ​ In 2018, the Company entered into a settlement agreement to jointly settle the Formaldehyde MDL and the Abrasion MDL. Under the terms of the settlement agreement, the Company agreed to fund $22 million (the “MDL Cash Payment”) and provide $14 million in store-credit vouchers for an aggregate settlement amount of $36 million to settle claims brought on behalf of purchasers of Chinese-manufactured laminate flooring sold by the Company between January 1, 2009 and May 31, 2015. The Court approved the settlement in the fourth quarter of, 2018 and the Company paid $21.5 million in cash into the plaintiffs’ settlement escrow account. ​ Cash and vouchers, which generally have a three-year life, were distributed by the administrator in the fourth quarter of 2020 upon order of the Virginia Court. The Company will monitor and evaluate the redemption of vouchers on a quarterly basis. ​ The $36 million aggregate settlement amount was accrued in 2017. The Company had held $21.5 million of the Settlement as a deposit pending the appeals and the distribution of cash by the administrator, which occurred in the fourth quarter of 2020. As of September 30, 2021, the remaining accrual related to these matters was $11.2 million for vouchers, which has been included in the caption “Accrual for Legal Matters and Settlements – Current” on its condensed consolidated balance sheet. ​ In addition to those purchasers who elected to opt out of the above settlement (the “Opt Outs”), there are a number of individual claims and lawsuits alleging personal injuries, breach of warranty claims or violation of state consumer protection statutes that remain pending (collectively, the “Related Laminate Matters”). Certain of these Related Laminate Matters were settled in 2019. The Company did not have any expense for these matters for the nine months ended September 30, 2021, or for the nine months ended September 30, 2020. As of September 30, 2021 and 2020, the remaining accrual related to these matters was ​ During the third quarter of 2021, the Company reached a settlement with its insurance carrier related to legal fees for the MDL matter for $0.4 million and received payment in October 2021. ​ Canadian Litigation On or about April 1, 2015, Sarah Steele (“Steele”) filed a purported class action lawsuit in the Ontario, Canada Superior Court of Justice against the Company. In the complaint, Steele’s allegations include strict liability, breach of implied warranty of fitness for a particular purpose, breach of implied warranty of merchantability, fraud by concealment, civil negligence, negligent misrepresentation and breach of implied covenant of good faith and fair dealing relating to the Company’s Chinese-manufactured laminate flooring products. Steele did not quantify any alleged damages in her complaint, but seeks compensatory damages, punitive, exemplary and aggravated damages, statutory remedies, attorneys’ fees and costs. While the Company believes that a further loss associated with the Steele litigation is reasonably possible, the Company is unable to reasonably estimate the amount or range of possible loss. ​ Section 301 Tariffs Since September 2018, pursuant to Section 301 of the Trade Act of 1974, the United States Trade Representative (“USTR”) has imposed tariffs on certain goods imported from China over four tranches or Lists. Products imported by the Company fall within Lists 3 and 4 for which tariffs range from 10% to 25%. On September 10, 2020 several importers of vinyl flooring filed a lawsuit with the CIT challenging the Section 301 tariffs under Lists 3 and 4. The Company has also filed a companion case at the CIT challenging Section 301 tariffs it has paid. The Company is unable to predict the timing or outcome of the ruling by the CIT. If these appeals are successful, the Company should qualify for refunds on these Section 301 tariffs. ​ Other Matters The Company is also, from time to time, subject to claims and disputes arising in the normal course of business. In the opinion of management, while the outcome of any such claims and disputes cannot be predicted with certainty, its ultimate liability in connection with these matters is not expected to have a material adverse effect on the Company’s results of operations, financial position or liquidity.

Fair Value of Financial Instruments	Fair Value of Financial Instruments ​ The carrying amounts of financial instruments such as cash and cash equivalents, accounts payable and other liabilities approximates fair value because of the short-term nature of these items.
Merchandise Inventories	Merchandise Inventories ​ The Company values merchandise inventories at the lower of cost or net realizable value. The method by which amounts are removed from inventory is weighted average cost. All of the hardwood flooring purchased from vendors is either prefinished or unfinished, and in immediate saleable form. The Company relies on a select group of international and domestic suppliers to provide imported flooring products that meet the Company’s specifications. The Company is subject to risks associated with obtaining products from abroad, including disruptions or delays in production, shipments, supply chain, delivery or processing, including due to the COVID-19 pandemic. The Company continues to execute contingency plans to minimize ongoing disruptions to supply chain, domestic distribution centers and store operations. Included in merchandise inventories are tariff-related costs, including Section 301 tariffs on certain products imported from China in recent years. A subset of these imports for certain click vinyl and other engineered products (the “Subset Products”) received an exemption that was made retroactive to the beginning of the Section 301 Tariffs for a period of time. The Company has deployed strategies to mitigate tariffs and improve gross margin, primarily through adjusting its pricing and promotion strategies and alternative country sourcing. The Company continues to monitor market pricing and promotional strategies to inform and guide its decisions. . ​ ​ ​ ​ ​ ​ ​ ​ Section 301 tariff ​ Corresponding approximate Event Timing level on imports Tariff level on percentage of Company's ​ ​ from China Subset Products merchandise subject to tariff Imposition of Tariffs September 2018 10% 10% then 0% 1 48% Increase in Tariffs June 2019 25% 25% then 0% 1 44% Retroactive Exemption on Subset Products 1 November 2019 25% 0% 10% Exemption Not Renewed and Tariffs Re-imposed on Subset Products August 2020 25% 25% 32% ​ September 30, 2021 25% 25% 22% 1 On November 7, 2019, the U.S. Trade Representative granted a retroactive exclusion to September 2018 on Subset Products as defined in the Section 301 Tariffs section above bringing the rate to 0%. ​
Recognition of Net Sales	Recognition of Net Sales The Company generates revenues primarily by retailing merchandise in the form of hard-surface and porcelain flooring and accessories. Additionally, the Company expands its revenues by offering services to deliver and/or install this merchandise for its customers; it considers these services to be separate performance obligations. The separate performance obligations are detailed on the customer’s invoice(s) and the customer often purchases flooring merchandise without purchasing installation or delivery services. Sales occur through a network of 422 stores, which spanned 47 states in the U.S. at September 30, 2021. In addition, both the merchandise and services can be ordered through a call center and from the Company’s digital platform, LLFlooring.com Revenue is based on consideration specified in a contract with a customer and excludes any sales incentives from vendors and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product to a customer or performing services for a customer. Revenues from installation and freight services are recognized when the delivery is made or the installation is complete, which approximates the recognition of revenue over time due to the short duration of service provided. The price of the Company’s merchandise and services is specified in the respective contract and detailed on the invoice agreed to with the customer including any discounts. The Company generally requires customers to pay a deposit, equal to approximately half of the retail sales value, when ordering merchandise not regularly carried in a given location or not currently in stock. In addition, the Company generally does not extend credit to its customers with payment due in full at the time the customer takes possession of merchandise or when the service is provided. Customer payments and deposits received in advance of the customer taking possession of the merchandise or receiving the services are recorded as deferred revenues in the accompanying condensed consolidated balance sheet caption “Customer Deposits and Store Credits.” The following table shows the activity in this account for the periods noted: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended ​ ​ September 30, ​ September 30, ​ 2021 2020 2021 2020 Customer Deposits and Store Credits, Beginning Balance ​ $ (67,731) ​ $ (55,492) ​ $ (61,389) ​ $ (41,571) New Deposits ​ (304,604) ​ (324,726) ​ (935,576) ​ (870,052) Recognition of Revenue ​ 282,229 ​ 295,833 ​ 867,063 ​ 793,491 Sales Tax included in Customer Deposits ​ 16,936 ​ 18,389 ​ 52,708 ​ 49,932 Other ​ 2,949 ​ 2,260 ​ 6,973 ​ 4,464 Customer Deposits and Store Credits, Ending Balance ​ $ (70,221) ​ $ (63,736) ​ $ (70,221) ​ $ (63,736) ​ Subject to limitations under the Company’s policy, return of unopened merchandise is accepted for 90 days, subject to the discretion of the store manager. The amount of revenue recognized for flooring merchandise is adjusted for expected returns, which are estimated based on the Company’s historical data, current sales levels, and forecasted economic trends. The Company uses the expected value method to estimate returns because it has a large number of contracts with similar characteristics. The Company reduces revenue by the amount of expected returns and records it within “Other Current Liabilities” on the condensed consolidated balance sheet. The Company continues to estimate the amount of returns based on historical data. In addition, the Company recognizes a related asset for the right to recover returned merchandise and records it in the “Other Current Assets” caption of the accompanying condensed consolidated balance sheet.

Cost of Sales	Cost of Sales ​ Cost of sales includes the cost of products sold, including tariffs, the cost of installation services, and transportation costs from vendors to the Company’s distribution centers or store locations. It also includes transportation costs from distribution centers to store locations, transportation costs for the delivery of products from store locations to customers, certain costs of quality control procedures, warranty and customer satisfaction costs, inventory adjustments including obsolescence and shrinkage, and costs to produce and ship samples, which are net of vendor allowances. The Company offers a range of limited warranties for the durability of the finish on its prefinished products to its services provided. These limited warranties range from one , with lifetime warranties for certain of the Company’s products. Warranty reserves are based primarily on claims experience, sales history and other considerations, including payments made to satisfy customers for claims not directly related to the warranty on the Company’s products. This warranty reserve was Vendor allowances mostly consist of volume rebates and are accrued as earned, with those allowances received as a result of attaining certain purchase levels accrued over the incentive period based on estimates of purchases. Volume rebates earned are initially recorded as a reduction in merchandise inventories and a subsequent reduction in cost of sales when the related product is sold. Reimbursement received for the cost of producing samples is recorded as an offset against cost of sales.
