Re:	5,000,000 Common Shares of OneSpaWorld Holdings Limited pursuant to Form S-8 Registration Statement

Dear Sirs:

We have acted as Bahamian counsel to OneSpaWorld Holdings Limited, a company incorporated under the laws of the Commonwealth of The Bahamas (the “Company”), in connection with the Registration Statement on Form S-8 (the “Registration Statement”) to be filed with the Securities and Exchange Commission (“SEC”) on or about this date under the Securities Act of 1933, as amended (the “Act”), for the registration of an aggregate of 5,000,000 common shares of (U.S.) $0.0001 par value each of the Company (the “Common Shares”) issuable under the Company’s Amended and Restated 2019 Equity Incentive Plan (the “Equity Shares”).

In that connection, we have examined originals or copies certified or otherwise identified to our satisfaction of: (i) the Registration Statement, including all exhibits thereto, as filed with the SEC; (ii) the Third Amended and Restated Memorandum of Association and Second Amended and Restated Articles of Association of the Company; and such other documents, corporate records and other instruments as we have deemed necessary for the purpose of this opinion. We have also examined and are familiar with the proceedings taken by the Company to authorize the issuance of the Equity Shares.
