ResearchThe best saunas
Ranked by our weighted methodology. The first fork in choosing a sauna is infrared versus traditional. Infrared cabins run cooler, warm up faster and often run on a standard outlet, which makes them easier to install indoors. Traditional heaters reach higher temperatures and produce steam with water on the rocks, but usually need a dedicated 240V circuit. After that, the questions are capacity, wood quality, electrical requirements and whether the cabin is rated for outdoor installation.

Common questions
Infrared or traditional — which should I choose?+
Infrared runs cooler, warms up faster and usually plugs into a standard 120V outlet, making it easy to install indoors. Traditional saunas reach higher temperatures and let you make steam, but need a dedicated 240V circuit. Choose infrared for convenience, traditional for an authentic high-heat experience.
Which saunas work on a standard 120V outlet?+
Most one- and two-person infrared cabins run on 120V. Larger infrared cabins and virtually all traditional electric saunas require a dedicated 240V circuit installed by an electrician.
Can a sauna go outdoors?+
Traditional barrel saunas are designed for outdoors. Some infrared cabins are weatherproofed for outdoor use, but infrared suits mild-to-moderate climates better than deep cold.
