SaunaNews
Hotels, resorts, spas, and commercial operators investing in sauna and thermal bathing experiences. Project news, design, and operator strategy.
World Spa’s model is a scale-and-circuit play: more thermal room types, longer dwell time, and a broad operating stack that combines bathing traditions, F&B, events, and private rentals. Co-founder Leonid Khanin frames the project as translational authenticity—rooted in source traditions, but deliberately designed for first-time urban guests and repeat local use.
North Conway has been named America's best ski town five times. It now has a communal sauna to match: two wood-fired rooms running a Harvia 50, three cold plunges, a Nordic cafe, and a Faraday cage that kills your phone signal. Walk-in only, $36, no reservations.

Portal° Thermaculture started behind a Boulder brewery, burned down, reopened in Denver six weeks later, and built its first real brick-and-mortar in a former Minneapolis Jiffy Lube cooled by a chiller designed for penguin tanks. Five metros, no disclosed investors, and a founder who says people need “a dive bar that doesn’t serve alcohol.”
Bathhouse opens its third New York City location, Bathhouse Atlantic Avenue, on Saturday, May 16, 2026, at 540 Atlantic Avenue in Downtown Brooklyn, two blocks west of Barclays Center. The build-out features five heat experiences anchored by a 100-plus-seat event sauna built for Aufguss programming, three thermal pools, a wood-fired Banya, an Infrared Sauna, and a Steam Room, with day passes starting at $29.
The engine room determines the guest room. The linen flow determines the guest satisfaction. Here is everything experienced thermal designers, architects, and operators know about bathhouse development that first-time operators learn the expensive way.

Tuli Lodge opened its third Seattle pop-up at Vulcan Real Estate’s Lake Union Piers, a 60,000-square-foot waterfront development. The move signals that developers are treating sauna as a pre-lease activation tool, a third capital model alongside venture-backed flagships and bootstrapped chains.

Therme Group hired a WhiteWater president and a Merlin Entertainments managing director in one week. But the entertainment-to-bathing talent migration runs far wider: a Meow Wolf co-founder, a Midas List VC, festival-circuit investors, trained theater performers, and nightclub operators are all building the next generation of bathing businesses. UNESCO classified Finnish sauna under festive events in 2020. The rest of the industry is catching up.
Portal Thermaculture opened its fourth US club in Bozeman, Montana, on March 17, 2026. The company has gone from Boulder pop-ups to brick-and-mortar clubs in Denver, Minneapolis, and now Bozeman in roughly 14 months, with no disclosed outside investors and a two-building layout designed to keep buildout costs far below the $3 million to $5 million custom-bathhouse norm.
Grotto Baths is preparing to open in Wynwood with two saunas, three kinds of pool, a steam room, an alcohol-free cafe and membership from $250 a month.

Therme Group and the University of Surrey have published the first standardized way to calculate the carbon footprint of a single spa visit: about 11 pounds of CO2 equivalent at a large facility, 7.7 at a small one. The operator's lesson is in the renewables split, and in what the announcements do not say about metering.
Three decisions made at commissioning set what your cold plunge legally is: how many bathers at once, in-ground or aboveground, and how often you drain it. Two of the things this trade has been told about New York, California and Utah turn out to be wrong.
Therme Group is now working inside the Marriott Design Lab on spa, fitness and guestroom concepts. Marriott doesn't buy sauna heaters, it writes the document that tells 7,939 franchisees what has to be in the building. That is the largest transmission belt this trade has ever been connected to, and nothing about it is signed yet.
Residents in two western French villages are fighting to preserve aging municipal pools that provide swimming lessons, heat relief and a place to spend an affordable afternoon. The numbers make no commercial sense, which is exactly why the public value is worth understanding.
