Saunas are having a moment. In the US, we’ve finally cottoned on to what the Finnish have known for centuries—that sweating it out makes you feel good. Sauna-stocked spas and wellness clubs (like Othership) keep popping up all over major cities, and ads for at-home saunas can be spotted on social media pages across the country.

But plenty of wellness hotels worldwide have been doing the sauna thing excellently for years. There are high-tech offerings, such as RXV Wellness Village in Thailand, which has a hyperbaric chamber for skin and tissue regeneration, an infrared sauna, and a cryo sauna for extra-speedy muscle recovery. Then there are the Finnish hotels, many of which have suites with in-room saunas, like Hotel Kämp in Helsinki. In the UK, plenty of lovely hotels are revamping their offerings: Soho Farmhouse in Oxfordshire recently expanded its spa to include various onsen tubs, three infrared sauna cabins and an ice hut, while at the Lake District’s Brimstone Hotel & Spa, you’re taken on a thermal journey around a sequence of Finnish, lava, and herbal saunas, before settling in for a blast in the Himalayan steam rooms.

Touted benefits of a sweat session include pain relief, deeper sleep, improved circulation and a glowing complexion, so working a few stints into your vacation is a no-brainer. For the top places to soak, steam and sweat yourself happy, see below for our editors’ picks of the best hotel saunas in the world to visit in 2025 and beyond.
