Gentlemen:

We have acted as counsel to EnviroStar, Inc., a Delaware corporation (the “Company”), with respect to the preparation and filing with the Securities and Exchange Commission of a Registration Statement on Form S-8 (the “Registration Statement”) relating to the offering and sale by the Company of up to an aggregate of 100,000 shares (the “Shares”) of the Company’s Common Stock, par value $0.025 per share (the “Common Stock”), under the EnviroStar, Inc. 2017 Employee Stock Purchase Plan (the “Plan”).

In connection with our opinion, we have examined the Registration Statement, including all exhibits thereto, as filed with the Securities and Exchange Commission on or about the date hereof, the Plan, the Company’s Certificate of Incorporation and Bylaws, in each case, as amended to date, as well as such other documents and proceedings as we have considered necessary for the purposes of this opinion. We have also examined and are familiar with the proceedings taken by the Company to authorize the Shares available for issuance under the Plan.

In rendering this opinion, we have undertaken no independent review of the operations of the Company. Instead, we have relied solely upon the documents and other information described above. In examining such documents, we have assumed, without independent investigation, (i) the authenticity of all documents submitted to us as originals, (ii) the conformity to original documents of all documents submitted to us as certified or photostatic copies, (iii) the authenticity of the originals of such latter documents and (iv) that actual information supplied to us was accurate, true and complete. In addition, as to questions of fact material to the opinions expressed herein, we have relied upon the accuracy of (i) all representations and warranties submitted to us for purposes of rendering the opinion and (ii) factual recitals made in the resolutions adopted by the Board of Directors of the Company.

Based upon and subject to the foregoing qualifications, assumptions and limitations, and the further limitations set forth below, and having regard to legal considerations which we deem relevant, we are of the opinion that, assuming (i) the Company reserves for issuance an adequate number of authorized and unissued shares of Common Stock and (ii) the Shares are issued and delivered by the Company against payment of adequate consideration therefor in accordance

with the terms and conditions of the Plan, the Shares issued under the Plan, if and when so issued, will be validly issued, fully paid and non-assessable.

We express no opinion as to any law of any jurisdiction, including federal securities laws or the “blue sky” laws of any state or jurisdiction, other than the laws of the State of Florida. This opinion letter is limited to the specific issues addressed herein, and no opinion may be inferred or implied beyond that expressly stated herein. This opinion letter is given as of the date hereof, and we do not undertake any liability or responsibility to inform you of any change in circumstances occurring, or additional information becoming available to us, after the date hereof that might alter the opinions contained herein.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended, or the rules and regulations of the Securities and Exchange Commission.
