(&#x201c;Holdings,&#x201d; and together with its wholly owned subsidiaries, the &#x201c;Company&#x201d;) was incorporated in Delaware in June 2012. The Company is a specialty retailer of natural stone and man-made tiles, setting and maintenance materials, and related accessories in the United States.  The Company manufactures its own setting and maintenance materials, such as thinset, grout, and sealers. The Company&#x2019;s primary market is retail sales to consumers, contractors, designers and home builders. As of September&#160;30, 2021, the Company had 143 stores in 31 states and the District of Columbia, with an average size of approximately 20,000 square feet. The Company has distribution centers located in Michigan, New Jersey, Oklahoma, Virginia and Wisconsin. The Company also has a sourcing office located in China. The accompanying Consolidated Financial Statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the rules and regulations for reporting on Form 10-Q. Accordingly, they do not include certain information and disclosures required for comprehensive financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included and are of a normal recurring nature, including the elimination of all intercompany transactions. Operating results for the three and nine months ended September&#160;30, 2021 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2021. These statements should be read in conjunction with the Consolidated Financial Statements and footnotes included in the Company&#x2019;s Annual Report on Form 10-K for the fiscal year ended December&#160;31, 2020. The accounting policies used in preparing these Consolidated Financial Statements are the same as those described in Note 1 to the Consolidated Financial Statements in such Form 10-K.    Impact of COVID-19 Pandemic In March 2020, the World Health Organization declared the COVID-19 outbreak a global pandemic.  COVID-19 has negatively impacted public health and the global economy, disrupted global supply chains, and created volatility in financial markets.  The continuing implications of COVID-19 on the Company remain uncertain and will depend on certain future developments, including the duration, scope and severity of the pandemic and the effects of new variants of COVID-19, some of which may be more virulent or transmissible than the initial strain; its impact on the Company&#x2019;s employees, customers and suppliers; the range and timing of government mandated restrictions and other measures, including the potential impact of the federal vaccination mandate on our labor supply and future results of operations; and the success of the deployment and widespread adoption of approved COVID-19 vaccines and their effectiveness against new variants of COVID-19. This uncertainty could have a material impact on the accounting estimates and assumptions utilized to prepare the Company&#x2019;s consolidated financial statements in future reporting periods, which could result in a material adverse impact on the Company&#x2019;s financial position, results of operations and cash flows. Recently Adopted Accounting Pronouncements In the first quarter of fiscal 2021, the Company adopted new accounting requirements related to the measurement of credit losses on financial instruments, including trade receivables. The new standard and subsequent amendments replaced the incurred loss impairment model with a forward-looking expected credit loss model, which will generally result in earlier recognition of credit losses. The Company&#x2019;s allowance for doubtful accounts represents its estimate of expected credit losses related to its trade receivables. To estimate the allowance for doubtful accounts, the Company leverages information on historical losses, current conditions, and reasonable and supportable forecasts of future conditions. Account balances are written off against the allowance when the Company deems the amount is uncollectible. The adoption of this standard did not have a material impact on the Company&#x2019;s consolidated financial statements. In the first quarter of fiscal 2021, the Company adopted a new accounting standard that simplifies accounting for income taxes.&#160; Specifically, the new standard simplifies aspects of accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill.&#160; The adoption of this standard did not have a material impact on the Company&#x2019;s consolidated financial statements.&#160; Accounting Pronouncements Not Yet Adopted In March 2020, the Financial Accounting Standards Board (FASB) issued guidance providing optional expedients and exceptions to account for the effects of reference rate reform to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued.  The optional guidance is effective as of the beginning of the reporting period when the election is made through December 31, 2022.  The Company is currently evaluating the impact this guidance will have on its consolidated financial statements.&#160;</us-gaap:BusinessDescriptionAndBasisOfPresentationTextBlock>

Sales taxes are excluded from revenues.   The following table presents revenues disaggregated by product category:                           For the three months ended For the nine months ended September&#160;30, September&#160;30, 2021 2020 2021 2020Man-made tiles 49%  46%  47%  46%Natural stone tiles 27   29   28   29 Setting and maintenance materials 14   14   14   14 Accessories 7   9   8   9 Delivery service 3   2   3   2 Total  100%  100%  100%  100% The Company generates revenues by selling tile products, setting and maintenance materials, accessories, and delivery services to its customers through its store locations and online.  The timing of revenue recognition coincides with the transfer of control of goods and services ordered by the customer, which falls into one of three categories described below: &#xf0b7;Revenue recognized when an order is placed &#x2013; If a customer places an order in a store and the contents of their order are available, the Company recognizes revenue concurrent with the exchange of goods for consideration from the customer.  &#xf0b7;Revenue recognized when an order is picked up &#x2013; If a customer places an order for items held in a centralized distribution center, the Company requests a deposit from the customer at the time they place the order.  Subsequently, when the contents of the customer&#x2019;s order are delivered to the store, the customer returns to the store and picks up the items that were ordered.  The Company recognizes revenue on this transaction when the customer picks up their order. &#xf0b7;Revenue recognized when an order is delivered &#x2013; If a customer places an order in a store and requests delivery of their order, the Company prepares the contents of their order, initiates the delivery service, and recognizes revenue once the contents of the customer&#x2019;s order are delivered. The Company determines the transaction price of its contracts based on the pricing established at the time a customer places an order.  The transaction price does not include sales tax as the Company is a pass-through conduit for collecting and remitting sales tax.  Any discounts applied to an order are allocated proportionately to the base price of the goods and services ordered.  Deposits made by customers are recorded in other accrued liabilities. Deferred revenues associated with customer deposits are recognized at the time the Company transfers control of the items ordered or renders the delivery service. In the event an order is partially fulfilled as of the end of a reporting period, revenue will be recognized based on the transaction price allocated to the goods delivered and services rendered. The customer deposit balance was $16.2 million and $12.2 million as of September&#160;30, 2021 and December 31, 2020, respectively.  Revenues recognized during the nine months ended September&#160;30, 2021 that were included in the customer deposit balance as of the beginning of the period were $12.0 million. The Company extends financing to qualified professional customers who apply for credit. Customers who qualify for an account receive 30-day payment terms. The accounts receivable balance was $3.3 million and $3.0 million at September&#160;30, 2021 and December 31, 2020, respectively. The Company expects that the customer will pay for the goods and services ordered within one year from the date the order is placed.  Accordingly, the Company does not adjust the promised amount of consideration for the effects of the financing component.   Customers may return purchased items for an exchange or refund.  The Company records a reserve for estimated product returns based on the historical returns trends and the current product sales performance.  The Company presents the sales returns reserve as an other accrued liability and the estimated value of the inventory that will be returned as an other current asset in the Consolidated Balance Sheet.  The components of the sales returns reserve reflected in the Consolidated Balance Sheet as of September&#160;30, 2021 and December 31, 2020 were as follows:          (in thousands)  September&#160;30, December 31,  2021 2020Other accrued liabilities $ 5,401 $ 4,957Other current assets   1,692   1,516Sales returns reserve, net $ 3,709 $ 3,441&#160;</us-gaap:RevenueFromContractWithCustomerTextBlock>

The Credit Agreement provides the Company with a senior credit facility consisting of a $100.0 million revolving line of credit through September 18, 2023. Borrowings pursuant to the Credit Agreement initially bear interest at a LIBOR or base rate. The LIBOR-based rate ranges from LIBOR plus 1.50% to 2.25% depending on the Company&#x2019;s rent adjusted leverage ratio.  The base rate is equal to the greatest of (a) the Federal funds rate plus 0.50%, (b) the Bank of America &#x201c;prime rate,&#x201d; and (c) the Eurodollar rate plus 1.00%, in each case plus 0.50% to 1.25% depending on the Company&#x2019;s rent adjusted leverage ratio. At September&#160;30, 2021, the base interest rate was 3.75% and the LIBOR-based interest rate was 1.59%. The Company had no borrowings outstanding on its revolving line of credit as of September&#160;30, 2021. In addition, the Company has standby letters of credit outstanding related to its workers&#x2019; compensation and medical insurance policies. Standby letters of credit totaled $2.4 million as of both September&#160;30, 2021 and December 31, 2020. There was $97.6 million available for borrowing on the revolving line of credit as of September&#160;30, 2021, which may be used to support the Company&#x2019;s growth and for working capital purposes. The Credit Agreement is secured by virtually all of the assets of the Company, including but not limited to, inventory, receivables, equipment and real property. The Credit Agreement contains customary events of default, conditions to borrowings, and restrictive covenants, including restrictions on the Company&#x2019;s ability to dispose of assets, make acquisitions, incur additional debt, incur liens, or make investments. The Credit Agreement also includes financial and other covenants, including covenants to maintain certain fixed charge coverage ratios and consolidated total rent adjusted leverage ratios. The Company was in compliance with the covenants as of September&#160;30, 2021.   &#160;</us-gaap:LongTermDebtTextBlock>

Leases generally have a term of ten to fifteen years, and contain renewal options. Assets acquired under operating leases are included in the Company&#x2019;s right of use assets in the accompanying Consolidated Balance Sheet. The Company&#x2019;s lease agreements do not contain significant residual value guarantees, restrictions or covenants. Leasehold improvements are amortized using the straight-line method over the shorter of the original lease term, the renewal term if the lease renewal is reasonably certain or the useful life of the improvement. Following the onset of COVID-19 in 2020, the Company worked with its landlords to defer rent payments for many of its retail locations throughout the second quarter of 2020.  As of December 31, 2020, the deferred rent balance was $2.1 million.  During the nine months ended September&#160;30, 2021, the Company repaid $1.9 million of the deferred rent balance to its landlords.  As of September&#160;30, 2021, the deferred rent balance was $0.2 million.  The deferred rent balance is recorded as a liability within the current portion of lease liability balance.

To measure fair value, the Company uses a three-tier valuation hierarchy based upon observable and non-observable inputs: Level 1 &#x2013; Unadjusted quoted prices that are available in active markets for the identical assets or liabilities at the measurement date. Level 2 &#x2013; Significant other observable inputs available at the measurement date, other than quoted prices included in Level 1, either directly or indirectly, including:&#xf0b7;Quoted prices for similar assets or liabilities in active markets;&#xf0b7;Quoted prices for identical or similar assets or liabilities in non-active markets; &#160;&#xf0b7;Inputs other than quoted prices that are observable for the asset or liability; and&#xf0b7;Inputs that are derived principally from or corroborated by other observable market data. Level 3 &#x2013; Significant unobservable inputs that cannot be corroborated by observable market data and reflect the use of significant management judgment.  The following table sets forth by level within the fair value hierarchy the Company&#x2019;s financial assets that were accounted for at fair value on a recurring basis at September&#160;30, 2021 and December&#160;31, 2020 according to the valuation techniques the Company uses to determine their fair values. There have been no transfers of assets among the fair value hierarchies presented.                      Pricing Fair Value at  Category September 30, 2021 December 31, 2020Assets   (in thousands)Cash and cash equivalents Level 1 $ 44,264 $ 9,617Restricted cash Level 1   655   655 The following methods and assumptions were used to estimate the fair value of each class of financial instrument.  There have been no changes in the valuation techniques used by the Company to value the Company&#x2019;s financial instruments. &#xf0b7;Cash and cash equivalents: Consists of cash on hand and bank deposits.  The value was measured using quoted market prices in active markets.  The carrying amount approximates fair value. &#xf0b7;Restricted cash: Consists of cash and cash equivalents held in bank deposit accounts restricted as to withdrawal or that are under the terms of use for current operations.  The value was measured using quoted market prices in active markets.  The carrying amount approximates fair value. Fair value measurements also apply to certain non-financial assets and liabilities measured at fair value on a nonrecurring basis.  Property, plant and equipment and right of use assets are measured at fair value when an impairment is recognized and the related assets are written down to fair value. During the three and nine months ended September 30, 2021, the Company recognized a $0.7 million charge in selling, general and administrative expenses to write-down property, plant and equipment and right of use assets to their estimated fair values. During the nine months ended September&#160;30, 2020, the Company recognized a $2.2 million charge in selling, general and administrative expenses to write-down property, plant, and equipment and right of use assets to their estimated fair values.  The Company measured the fair value of these assets based on projected cash flows, an estimated risk-adjusted rate of return, and market rental rates for comparable properties.  Projected cash flows are considered Level 3 inputs.  Market rental rates for comparable properties are considered Level 2 inputs. No impairment charges were recorded during the three months ended September 30, 2020. During the nine months ended September&#160;30, 2021, the Company recorded a $1.1 million adjustment to reflect an increase in the fair value to restore leased property to its original condition at the end of the lease.  The change in the estimated value of the Company&#x2019;s asset retirement obligation resulted in a $1.1 million increase in property, plant and equipment, a $0.1 million increase in other current liabilities, and a $1.0 million increase in other long-term liabilities.  The Company measured the fair value of its asset retirement obligation based on the estimated amounts and timing of settlements, an estimated risk adjusted rate of return, and expected inflation rates, which are considered Level 2 inputs.&#160;</us-gaap:FairValueDisclosuresTextBlock>

      id="ct-nonNumeric-f7b17963-22b8-46f5-9158-e8de208d49a2">Note 10: Equity Incentive Plans At the Annual Meeting of Stockholders held on July 20, 2021 (the &#x201c;Annual Meeting&#x201d;), the Company&#x2019;s stockholders approved the 2021 Omnibus Equity Compensation Plan (the &#x201c;2021 Plan&#x201d;). The 2021 Plan replaced 2012 Omnibus Award Plan (the &#x201c;Prior Plan&#x201d;). No new awards will be granted under the Prior Plan after the date of the Annual Meeting. However, the Company granted equity awards under the Prior Plan to the Company&#x2019;s non-employee directors on the date of the Annual Meeting, and all awards granted under the Prior Plan that were outstanding on the date of stockholder approval of the 2021 Plan will remain outstanding in accordance with their terms. The maximum number of shares that may be delivered with respect to awards under the 2021 Plan is 3,500,000 shares, subject to adjustment in certain circumstances. Shares tendered or withheld to pay the exercise price of a stock option or to cover tax withholding will not be added back to the number of shares available under the 2021 Plan. To the extent that any award under the 2021 Plan, or any award granted under the Prior Plan prior to stockholder approval of the 2021 Plan, is forfeited, canceled, surrendered or otherwise terminated without the issuance of shares or an award is settled only in cash, the shares subject to such awards granted but not delivered will be added to the number of shares available for awards under the 2021 Plan.  Stock options: The Company measures and recognizes compensation expense for all stock based awards at fair value. The financial statements for the three and nine months ended September&#160;30, 2021 and 2020 include compensation expense for the portion of outstanding awards that vested during those periods. The Company recognizes stock based compensation expenses on a straight-line basis over the requisite service period of the award, which is generally the option vesting term. Total stock based compensation expense related to stock options was $0.1 million for both the three months ended September&#160;30, 2021 and 2020. Total stock based compensation expense related to stock options was $0.3 million for both the nine months ended September&#160;30, 2021 and 2020. Stock based compensation expense pertaining to stock options is included in selling, general and administrative expenses in the accompanying Consolidated Statements of Operations. As of September&#160;30, 2021, the Company had outstanding stock options to purchase 992,695 shares of common stock at a weighted average exercise price of $10.91. Restricted stock: The Company awards restricted common shares to selected employees and to non-employee directors. Recipients are not required to provide any consideration upon vesting of the award. Restricted stock awards are subject to certain restrictions on transfer, and all or part of the shares awarded may be subject to forfeiture upon the occurrence of certain events, including employment termination. Certain awards are also subject to forfeiture if the Company fails to attain certain performance targets. The restricted stock is valued at its grant date fair value and expensed over the requisite service period or the vesting term of the awards. The Company adjusts the cumulative expense recognized on awards with performance conditions based on the probability of achieving the performance condition. Total stock based compensation expense related to restricted stock was $0.5 million for both the three months ended September&#160;30, 2021 and 2020. Total stock based compensation expense related to restricted stock was $1.6 million and $1.3 million for the nine months ended September&#160;30, 2021 and 2020, respectively. Stock based compensation expense pertaining to restricted stock awards is included in selling, general and administrative expenses in the accompanying Consolidated Statements of Operations. As of September&#160;30, 2021, the Company had 1,355,707 outstanding restricted common shares.&#160;</us-gaap:DisclosureOfCompensationRelatedCostsShareBasedPaymentsTextBlock>

      id="ct-nonNumeric-912a9cab-dd8b-40d7-8dfb-7854363b8f1f">Note 11: New Markets Tax Credit 2016 New Markets Tax Credit In December 2016, the Company entered into a financing transaction with U.S. Bank Community, LLC (&#x201c;U.S. Bank&#x201d;) related to a $9.2 million expansion of the Company&#x2019;s facility in Durant, Oklahoma. U.S. Bank made a capital contribution to, and Tile Shop Lending, Inc. (&#x201c;Tile Shop Lending&#x201d;) made a loan to, Twain Investment Fund 192 LLC (the &#x201c;Investment Fund&#x201d;) under a qualified New Markets Tax Credit (&#x201c;NMTC&#x201d;) program. The NMTC program was provided for in the Community Renewal Tax Relief Act of 2000 (the &#x201c;Act&#x201d;) and is intended to induce capital investment in qualified lower income communities. The Act permits taxpayers to claim credits against their federal income taxes for up to 39% of qualified investments in the equity of community development entities (&#x201c;CDEs&#x201d;). CDEs are privately managed investment institutions that are certified to make qualified low-income community investments. In this transaction, Tile Shop Lending loaned $6.7 million to the Investment Fund at an interest rate of 1.37% per year and with a maturity date of December 31, 2046. The Investment Fund then contributed the loan to a CDE, which, in turn, loaned the funds on similar terms to Tile Shop of Oklahoma, LLC, an indirect, wholly-owned subsidiary of Holdings. The proceeds of the loans from the CDEs (including loans representing the capital contribution made by U.S. Bank, net of syndication fees) were used to partially fund the distribution center project.    In December 2016, U.S. Bank contributed $3.2 million to the Investment Fund and, by virtue of such contribution, is entitled to substantially all of the tax benefits derived from the NMTC, while the Company effectively received net loan proceeds equal to U.S. Bank&#x2019;s contributions to the Investment Fund. This transaction includes a put/call provision whereby the Company may be obligated or entitled to repurchase U.S. Bank&#x2019;s interest. The Company believes that U.S. Bank will exercise the put option in December 2023 at the end of the recapture period. The value attributed to the put/call is de minimis. The NMTC is subject to 100% recapture for a period of seven years as provided in the Internal Revenue Code. The Company is required to be in compliance with various regulations and contractual provisions that apply to the NMTC arrangement. Non-compliance with applicable requirements could result in projected tax benefits not being realized and, therefore, could require the Company to indemnify U.S. Bank for any loss or recapture of NMTCs related to the financing until such time as the obligation to deliver tax benefits is relieved. The Company does not anticipate any credit recaptures will be required in connection with this arrangement.    The Company has determined that the financing arrangement with the Investment Fund and CDEs constitutes a variable interest entity (&#x201c;VIE&#x201d;). The ongoing activities of the Investment Fund &#x2013; collecting and remitting interest and fees and NMTC compliance &#x2013; were all considered in the initial design and are not expected to significantly affect economic performance throughout the life of the Investment Fund. Management considered the contractual arrangements that obligate the Company to deliver tax benefits and provide various other guarantees to the structure; U.S. Bank&#x2019;s lack of a material interest in the underlying economics of the project; and the fact that the Company is obligated to absorb losses of the Investment Fund. The Company concluded that it is the primary beneficiary of the VIE and consolidated the Investment Fund, as a VIE, in accordance with the accounting standards for consolidation. In 2016, U.S. Bank&#x2019;s contributions of $3.2 million, net of syndication fees, were included in cash, restricted cash, other accrued liabilities and other long-term liabilities in the consolidated balance sheet. The Company incurred $1.3 million of syndication fees in connection with this transaction, which were classified as other current assets and other non-current assets in the consolidated balance sheet. The Company is recognizing the benefit of this net $1.9 million contribution over the seven-year compliance period as it is being earned through the on-going compliance with the conditions of the NMTC program. As of September&#160;30, 2021, the balance of the contribution liability for this arrangement was $1.0 million, of which $0.5 million was classified as other accrued liabilities on the Consolidated Balance Sheet and $0.5 million was classified as other long-term liabilities on the Consolidated Balance Sheet. The Company is able to request reimbursement for certain expenditures made in connection with the expansion of the distribution center in Durant, Oklahoma from the Investment Fund. Expenditures that qualify for reimbursement include building costs, equipment purchases, and other expenditures tied to the expansion of the facility. As of September&#160;30, 2021, the remaining balance in the Investment Fund available for reimbursement to the Company was $0.7 million.&#160;</cik0001552800:NewMarketTaxCreditDisclosureTextBlock>

Rucker, the Company&#x2019;s former Interim Chief Executive Officer and President, former member of the Company&#x2019;s Board of Directors, and former holder of more than 5% of the Company&#x2019;s common stock as of September&#160;30, 2021, informed the Company he had reacquired a majority of the equity of one of its key vendors, Nanyang Helin Stone Co. Ltd (&#x201c;Nanyang&#x201d;). Mr. Nishi also has an ownership interest in Tilestyling Co. Ltd (&#x201c;Tile Style&#x201d;), a vendor from which the Company started acquiring product in 2020. Nanyang and Tile Style supply the Company with natural stone products, including hand-crafted mosaics, listellos and other accessories. The Company paid $7.6 million to Nanyang in connection with purchases made during the year ended December&#160;31, 2020. During the three and nine months ended September&#160;30, 2021, the Company purchased $2.9 million and $6.2 million of products from Nanyang, respectively. As of September&#160;30, 2021, there were no accounts payable due to Nanyang. The Company paid $0.7&#160;million to Tile Style in connection with purchases made during the year ended December&#160;31, 2020. During the three and nine months ended September&#160;30, 2021, the Company purchased $1.0 million and $2.1 million of products from Tile Style, respectively. As of September&#160;30, 2021, the accounts payable due to Tile Style was $0.1 million. Mr. Nishi&#x2019;s employment with the Company was terminated on January&#160;1, 2014 as a result of several violations of the Company&#x2019;s code of business conduct and ethics policy. Certain of those violations involved his undisclosed ownership of Nanyang at that time.  Management and the Audit Committee have evaluated these relationships and determined that it would be in the Company&#x2019;s best interests to continue purchasing products from Nanyang and to begin purchasing products from Tile Style. The Company believes Nanyang and Tile Style each provide an important combination of quality, product availability and pricing, and relying solely on other vendors to supply similar product to the Company would not be in the Company&#x2019;s best interests. The Company and the Audit Committee will continue to review future purchases from Nanyang and Tile Style and compare the pricing for products purchased from each of Nanyang and Tile Style to the pricing of same or similar products purchased from unrelated vendors.</us-gaap:RelatedPartyTransactionsDisclosureTextBlock>
