Gurney’s Montauk Resort Debuts Newly Renovated Seawater Spa

From the team behind Manhattan’s Aire Ancient Baths comes a reimagined spa at the iconic Gurney’s.

Just in time for summer, Gurney’s Montauk Resort has unveiled its Seawater Spa, North America’s only thalassotherapy spa, following an extensive $20 million renovation. The update enhanced innovation, sustainability, and holistic wellness offerings at the 30,000-square-foot spa. Featuring the only ocean-fed seawater pool in the country, it also offers a full bathhouse experience with a caldarium, thermae bath, sauna and steam, a salt room, indoor-outdoor treatment suites overlooking the Atlantic Ocean, a curated indoor-outdoor wellness space with cardio and weight equipment, a movement studio, and more.

As part of the launch, the resort is now offering exclusive spa memberships, which provide guests and locals the opportunity the enjoy unlimited access to the facilities and treatments. The spa membership is one of the brand’s three new memberships—Resort, Spa, and All-Access —offering members a chance to enjoy all Gurney’s Montauk has to offer, including exclusive access to the Beach Club, concierge services, and the year-round Seawater Spa. New spa members also receive one-on-one fitness coaching, wellness classes, and curated spa treatments. Memberships start at $17,500.

 “We are very excited to bring a new Seawater Spa to our guests, members, and community, allowing access to a level of facilities, treatments, and amenities not previously available in Montauk,” says owner George Filopoulos. “After the challenges of the past couple of years, we’ve learned how important prioritizing wellness is, and we are happy to bring this completely new and elevated experience to the Hamptons.”

The beloved Gurney’s Montauk has long been a Long Island favorite. With the debut of the new spa, it is set to elevate wellness in the Hamptons. With the intention of creating an unparalleled holistic wellness experience, Gurney’s Montauk turned to Alonso Designs, the team behind New York City’s Aire Ancient Baths; treatment specialist Dr. Dennis Gross; and leading wellness brands, including Biologique Recherche, OSEA, QMS Medicosmetics, Voya, and Aesop.

Sustainable by Design

Reimagined by architect Ignacio Alonso, the spa added a new event space to the property, The Spa Deck, a venue created on the rooftop of the spa. Ideal for weddings and large groups, the deck provides panoramic views of the ocean. One of the main design objectives was to take advantage of the picturesque waterfront. As a result, the spa offers treatment rooms with direct ocean views and dedicated outdoor spaces for seaside treatments.

The interiors also capture the oceanside setting with the use of natural materials and tones that match the colors and texture of the environment. To enhance the connection to the ocean, all the pools have a custom-designed infinity drain that blurs the edge between the ocean and spa water.

With a passion for sustainability, Gurney’s Resorts and Alonso Designs sourced and installed environmentally friendly and energy-efficient mechanical and water treatment systems for the new spa. Advancing Gurney’s commitment to lessening its impact on the environment, the spa was designed with features that maximize performance, efficiency, and user friendliness, from filters that reduce water waste to energy-saving heating systems to the use of UV to limit the need for harmful chemicals.

Spa Updates

Thanks to the two-year renovation, the new facility include tranquil co-ed relaxation areas and eucalyptus oil-infused aromatherapy steam rooms. The resort’s existing saltwater swimming pool fed directly by the Atlantic Ocean has been renovated and is now complemented with four new bathhouse experiences: a large caldarium, thermae, and a dual frigidarium. All come with views of the ocean.

In the fitness center, guests will find equipment from Peloton and Technogym. There are also dedicated areas for cardio, strength, and a selection of studios for group fitness classes. The gym also features ocean views. 

With treatments from some of the industry’s top brands, the Seawater Spa also serves as an outpost for bespoke facials and skincare treatments from Dr. Dennis Gross. The menu also features massages, body treatments, and more. All treatments provide access to the pools and bathhouse facilities.

“The new Seawater Spa only adds to the already vibrant environment at our resort, creating the opportunity for a balanced experience,” says Filopoulos. “Whether visiting for a full wellness reset or looking to incorporate health, fitness, and beauty into a beach vacation or winter getaway, our guests will find a wide array of amenities and activities at our new Seawater Spa.”
