Spa & Sauna

Ecotone is the premiere choice for luxury spa design and construction in the greater NYC area.

We Create the Perfect Luxury Spa Environment

Ecotone specializes in designing and building natural spaces for rejuvenation. In the busiest city in America, our clients depend on us to help them relax to find their best selves. We strive to give the people of New York much-needed respite from the pace of urban life. Our nature-inspired, meticulously crafted spas and saunas can be found all over the greater New York area, from Manhattan skyscrapers to ocean-front compounds in the Hamptons. Design, construction, insurance compliance, and DOH regulation; there are no challenges our design and construction experts can’t handle.

Selected projects

1 Hudson Yards

Hudson Yards, Manhattan

This commercial-grade, high-rise spa was one of the first projects completed in the Hudson Yards complex. We coordinated with MEP engineers, the architect of record, and top engineering firms in the city to design and build a custom sauna and steam room. The final project included textured walls, custom benches, a heat retention system, a two-layer sauna structure wall, and custom onsite millwork, stonework, and glasswork.

Gurney’s Spa

Mountauk, NY

Gurney’s is one of the oldest, most-well known spas in Montauk, Long Island. For this extensive project, we performed construction coordination and technical design, installed custom benches with light cove detail, and created a variety of custom shop-fabricated millwork and glasswork.

Hard Rock Spa

Atlantic City, NJ

This high-profile job required custom double-tiered sauna benches with backrests and light coves as well as all of the wall panels. Ecotone designed and custom fabricated the spa and closely coordinated installation with the New Jersey union trades to make sure everything was installed correctly and up to code.

There’s nothing quite like building a spa on the 60th floor of a Manhattan skyscraper. Insurance concerns, city regulations, and other countless logistical roadblocks have stymied even the best construction companies, but these challenging conditions are where our experts shine. We have decades of combined experience navigating New York’s labyrinth of insurance and building regulations. We’re proud of our “A-Team” reputation as the specialists other companies call when a project gets stuck.

“Out of the box” is not in our vocabulary. All of our designs are 100% custom-made to match the unique needs of your project.

Their attention to detail is second to none. Craig personally makes sure that any piece of wood installed comes to life and looks like it belonged there the whole time.

The Ecotone studio is currently located in Red Hook, Brooklyn. We have executed projects all over New York City, from skyscrapers in the heart of Manhattan to residential buildings in the outlying boroughs. We’ve even taken on larger projects as far as Montauk, Long Island, and Atlantic City, New Jersey. Send us a message to see if you’re within our project range!


Primarily Manhattan, Brooklyn, and Queens. We travel for suitable projects and have executed complete projects from Saltwater Spas in Montauk to Casino Spas in Atlantic City.

Absolutely! We can do all phases of the process, including design, construction management, ADA and DoH compliance, full-phase oversight, cost management, and quality assurance.

The design phase starts at $6,500, including conceptual design and construction documents. Complete construction, which comprises custom fabrication and builds, delivery, installation, coordination, and handover, costs roughly $75,000, or from $1 to $5 million on commercial-grade spas.     

Ecotone usually works on commercial projects but occasionally does residential projects when commercial-grade amenities are needed or requested.
