Types of Outdoor Saunas
Barrel Saunas
The most common outdoor sauna style in North America. Heat circulation benefits from the curved interior, faster heat-up than cabin saunas, self-draining roof, and structural strength. Sweat Kingdom's Sweat Barrel is handcrafted in East Idaho with Western Red Cedar and HUUM/Harvia heaters.
Cabin Saunas
Maximum interior space with flexible bench layouts. Can include changing rooms and porches. Sweat Kingdom's Sweat Cabin offers 4 to 6 person capacity with custom options, wool-insulated walls, and Western Red Cedar throughout.
Outdoor Infrared Saunas
Peak Saunas offers weather-resistant infrared cabins with full-spectrum IR, red light therapy, smart WiFi, and stated ultra-low EMF. The El Capitan (4-person) and Kilimanjaro (5-person) are purpose-built for outdoor use.
