Check before you buy

Heat type. Traditional heaters heat the air for the classic high-heat, steam-on-rocks session. Infrared panels warm the body directly at lower air temperatures. This decides the whole experience, the electrical needs and the warm-up time.
Electrical requirement. Most traditional sauna heaters and larger infrared units need a dedicated 240V circuit. Confirm the circuit before you buy. Installation cost and feasibility often depend on this more than on the sauna itself.
Heater sizing. Match the heater's rated output to the sauna's interior volume, following the heater maker's room-size chart. An undersized heater never reaches temperature, especially outdoors in cold weather.
Outdoor rating. For outdoor use, choose a model the manufacturer rates for outdoor installation, with a proper roof covering and a raised, level base. Indoor-only cabins can warp, leak and rot when exposed to weather.
Wood species. Prefer thick, kiln-dried softwoods such as cedar, spruce or hemlock that stay cool to the touch. Wood quality affects durability, comfort on the benches and resistance to cracking.

Questions

Infrared or traditional?

Traditional gives high air heat and steam from water on hot rocks. Infrared runs at lower air temperatures and warms you directly. Pick the experience you actually want.
