What you need to know before buying
- A licensed electrician is required to provide a dedicated 208 to 240V single-phase circuit and breaker. A licensed plumber connects the water supply and drain.
- Controls and steam head are sold separately. You need one ThermaSol control (ThermaTouch, SignaTouch or MicroTouch) and one SteamVection or Legacy 1/2" (OSS) steam head.
- Size by steam room volume: multiply length x width x height in cubic feet and choose a generator rated at or above that number. Per ThermaSol, size up one model for a 9 ft ceiling and two models for a 10 ft ceiling. Confirm your wall material and layout against ThermaSol's sizing guide or send us your dimensions before ordering.
- Install the generator flat and level in a finished, climate-controlled space with at least 6 inches of clearance on all sides, and keep it accessible for service.
- Build the steam enclosure from non-porous, moisture-resistant materials such as porcelain or ceramic tile, tempered glass and sealed grout.
