RE:    Registration Statement on Form S-1

Ladies and Gentlemen:

We have acted as counsel to Select Interior Concepts, Inc., a Delaware corporation (the “Company”), in connection with the Company’s filing of a Registration Statement on Form S-1 (as may be amended, the “Registration Statement”) with the U.S. Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), on the date hereof. The Registration Statement relates to the registration under the Securities Act of sales by the selling stockholders of the Company named therein (the “Selling Stockholders”) of up to 25,614,626 shares (the “Shares”) of Class A common stock, par value $0.01 per share, of the Company. We have been requested by the Company to render this opinion with respect to the legality of the Shares in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

In rendering the opinion expressed below, we have acted as counsel for the Company and have examined and relied upon originals (or copies certified or otherwise identified to our satisfaction) of (i) the Amended and Restated Certificate of Incorporation of the Company, filed as Exhibit 3.1 to the Registration Statement, (ii) the Amended and Restated Bylaws of the Company, filed as Exhibit 3.2 to the Registration Statement, (iii) the Registration Statement, (iv) the prospectus contained within the Registration Statement (the “Prospectus”), and (v) such corporate records, documents, agreements and instruments of the Company, certificates of public officials, certificates of officers of the Company, resolutions of the Company’s board of directors and committees thereof, and such other records, documents, agreements, certificates and instruments, and have examined such questions of law and have satisfied ourselves as to such matters of fact, as we have deemed relevant and necessary as a basis for the opinion set forth herein. In our examination, we have assumed, without independent investigation, the authenticity of all documents submitted to us as originals, the genuineness of all signatures, the legal capacity of all natural persons who have executed any of the documents reviewed by us, and the conformity with the original documents of any copies thereof submitted to us for our examination. We have also assumed the accuracy of all other information provided to us by the Company during the course of our investigations, on which we have relied in issuing the opinion expressed below.

Based upon the foregoing, and subject to the assumptions, qualifications and limitations set forth herein, we are of the opinion that the Shares being offered by the Selling Stockholders have been duly authorized by all necessary corporate action of the Company, validly issued and fully paid, and are non-assessable, and the Shares, upon sale, delivery and payment therefor, in an amount not less than the par value thereof, in the manner contemplated by the Prospectus, are validly issued, fully paid and non-assessable.
