The BathHouse

The BathHouse is a true multi-dimensional thalassotherapy wellness experience in a serene environment overlooking the ocean. BathHouse sessions may be reserved in 50-minute increments by adult resort guests, members, and spa day guests receiving treatments of one hour or longer. Visit the BathHouse section of the Seawater Spa Services page for full details.

The BathHouse is restricted to adults ages 18 and older. As there is limited availability, we encourage all guests to schedule their BathHouse experience as far in advance as possible. All BathHouse experiences must be scheduled directly with Seawater Spa by phone at 1-631-668-1892.

Spa Treatments

The Seawater Spa is a vibrant wellness ecosystem designed to inspire and heal. Rejuvenate with seawater and marine-based therapies, advanced skincare, and therapeutic bodywork during your visit.


All spa services are reserved for adults ages 18 and up. A mandatory gratuity of 20% is applied to all Spa treatments. The 20% is paid out in its entirety to your therapist.  An additional 2% administrative fee is also provided and is used to offset costs and expenses associated with your treatment; this charge is not a gratuity and is not paid directly to any spa employee. The full 22% is subject to applicable sales tax.
