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, 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, waterproof 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 March 31, 2020, the Company’s stores spanned 47 states in the United States (“U.S.”) and included eight stores in Canada. 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 website, 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, 2019. 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 months ended March 31, 2020 are not necessarily indicative of future results to be expected for the full year due to a number of factors, including seasonality and general economic conditions that may impact sales for the remainder of fiscal 2020. Impact of the COVID-19 Pandemic On March 11, 2020, the World Health Organization announced that infections of COVID-19 had become a pandemic, and on March 13, 2020, the U.S. President announced a National Emergency relating to the COVID-19 pandemic. The Company is uncertain of the magnitude of the adverse impact of the COVID-19 pandemic to its sales, supply chain, and distribution as well as to the overall economy and consumer spending, including the construction-renovation industry. The Company currently anticipates that disruptions resulting from COVID-19 will have a material negative impact on its sales and results of operations, financial position, and cash flows during 2020. While these potential negative effects will not be fully reflected in the Company's results of operations and overall financial performance until future periods, the Company has already experienced an impact to financial results due to the COVID-19 pandemic. Most notably, starting as of the week of March 22, 2020 the Company closed as many as 56 stores for a period of time while all other stores operated under reduced hours and/or warehouse-only conditions, offering curbside pickup and job site delivery for our Pro and DIY customers. The Company’s comparable store sales results were down from the prior year by approximately 45% in the last week of the month of March. As of the date of this report, in compliance with local and state regulatory orders, approximately 60% of our stores are fully operational, approximately 25% are scheduling appointments to allow customers to visit our showrooms, and approximately 15% are utilizing our warehouse-only model, while less than 10 stores remain closed.
