Beyond the Cold Plunge: 7 Luxury Hotels Rethinking Thermal Wellness
From Japanese hot springs and guided Alpine sauna rituals to cryotherapy and elaborate hydrotherapy circuits, these seven hotels are taking thermal wellness beyond the expected.
Contrast therapy may be having a wellness moment, but alternating between hot and cold is hardly new. The Romans built bathhouses around shifts in temperature, while Finland’s sauna culture is so deeply rooted in daily life that UNESCO recognizes it as part of the country’s intangible cultural heritage. Japan’s centuries-old onsen tradition has similarly made bathing about far more than simply getting clean.
What has changed is how luxury hotels and resorts are interpreting these traditions. The standard sauna-and-cold-plunge pairing has expanded into hydrotherapy circuits, guided sauna rituals, mineral-rich hot springs, cryotherapy and even warm-water bodywork. Some stay closely tied to the traditions of their surroundings; others borrow bathing practices from around the world. Here are seven places taking hot, cold and water in more interesting directions.
Amanemu | Ise-Shima, Japan
At Amanemu, water doesn't need much technological intervention. The resort sits within Ise-Shima National Park overlooking Ago Bay, with access to naturally occurring mineral-rich hot spring water that supplies private plunge baths in its 24 suites and eight villas. The 21,528-square-foot Aman Spa extends that onsen tradition with outdoor thermal springs, two private onsen pavilions, a dry sauna, steam room and dedicated hydrotherapy facilities.
One of the more distinctive experiences is Yakuyu, a Japanese herbal onsen ritual offered in the private pavilions. The baths combine the region’s hot spring culture with herbs and botanicals drawn from Japan’s Kampo tradition. Amanemu also offers Watsu in a private pool surrounded by nature, where a practitioner guides guests through floating stretches, massage and acupressure. Rather than chasing ever more extreme temperatures, Amanemu is a reminder that hydrotherapy can be quiet, slow and deeply tied to the place where the water comes from.
JOALI BEING | Bodufushi, Maldives
At JOALI BEING, even the hydrotherapy space comes with a design story. Kaashi, the resort’s hydrotherapy hall, takes inspiration from the life cycle of a coconut, using water and temperature as part of a progression rather than treating the sauna or plunge as a standalone experience.
Inside, the options pull from bathing traditions around the world. There’s a Russian-style banya, an Aufguss sauna, a traditional Turkish hammam and a salt inhalation room, along with sensory showers and a dedicated hydrotherapy pool. Warm-water Watsu pools take things in a gentler direction, with treatments centered on floating, stretching and bodywork. The result is less a single contrast circuit than a choose-your-own hydrotherapy journey—and a good reason to spend considerably more time indoors than you might expect in the Maldives.
FAENA New York New York City
There’s nothing particularly minimalist about Tierra Santa Healing House at Faena New York, including its approach to hydrotherapy. The 17,000-square-foot West Chelsea wellness space is filled with pistachio green and peony pink, marble, botanical imagery and artwork, including Juan Gatti’s surreal compositions surrounding the hydrotherapy area.
At the center are five hydrotherapy pools: two warm pools, a hot pool, a cold plunge and a saltwater pool, with cabana loungers nearby for resting between rounds. An authentic hammam finished with Brazilian amazonite stone joins a steam room, dry sauna and infrared sauna, giving guests plenty of ways to create their own hot-cold circuit. In a city where wellness can easily become another appointment on the calendar, Tierra Santa gives you a reason to stay awhile.
The Alpina Gstaad | Gstaad, Switzerland
At The Alpina Gstaad, hot and cold take several forms. The 2,000-square-meter Six Senses Spa pairs traditional thermal experiences—including hot and cold plunge pools, steam and ice showers—with newer technology. A three-minute full-body cryotherapy session delivers the most extreme dose of cold, while the surrounding Swiss Alps provide an appropriately wintry backdrop.
But one of the spa’s most striking spaces doesn't involve temperature extremes at all. The Himalayan salt room glows pink from floor to ceiling, with loungers in a space that feels worlds away from the clinical chill of cryotherapy. It’s an unexpected pairing: high-tech recovery followed by a much slower place to simply sit and unwind.
Manoir Hovey | North Hatley, Québec, Canada
Set along the shores of Lake Massawippi, Manoir Hovey brings Québec’s landscape directly into its thermal experience. Centuries-old pines surround Le Spa Manoir Hovey, where the year-round Thermal Circuit moves guests through heat, cold and rest with an outdoor heated pool, whirlpools, dry cedar sauna, aromatic hammam and cold plunge pool.
What makes the experience especially restorative is how closely it remains connected to the outdoors. Between rounds of heat and cold, guests can retreat to light-filled relaxation rooms with expansive windows overlooking the forest and lake. The scenery shifts dramatically with Québec’s four seasons, making fresh air, water and the surrounding landscape as much a part of the ritual as the thermal circuit itself.
Hotel Nesslerhof | Grossarl, Austria
At Hotel Nesslerhof in Austria’s Grossarl Valley, sauna isn't something guests are simply left to figure out themselves. The hotel has five sauna and steam experiences, including a Swiss stone pine sauna and an outdoor sauna, but it’s the guided rituals that make the heat here more interesting.
Sauna masters Ignaz, Leo and Freddi lead daily infusions using Alpine herbs, aromatic essential oils, sound and choreographed movements. Guests can also start the day forest bathing in the valley before returning to the spa for heat later on. In a country with a long sauna tradition, Nesslerhof makes the person leading the ritual nearly as important as the sauna itself.
Four Seasons Hotel Minneapolis Minneapolis, Minnesota
In a city that knows a thing or two about cold weather, Four Seasons Hotel Minneapolis leans into the Nordic approach. Its 75-minute private Nordic Sauna ritual is built around thermic cycling, with guests moving between heat, cold, rest and hydration at their own pace rather than following a prescribed schedule.
Optional aromatherapy and traditional löyly—the Finnish practice of pouring water over hot sauna stones to create steam—turn up the heat before guests decide when, or whether, to cold plunge, cool off outdoors or simply rest. A Sauna Guide sets up the experience but leaves the rhythm to each guest, and the reservation includes day access to the hotel’s indoor pool and thermal amenities. The temperatures may be extreme, but the pace is entirely your own.
