ThermaSol FAQ

ThermaSol sauna or steam shower: which fits my home?

A sauna gives dry heat from a heater and stones, with bursts of steam when you add water. A steam shower fills an enclosed shower with moist heat at lower temperatures and can fit within an existing bathroom footprint. Space, budget and whether you prefer dry or moist heat usually decide it.

How heavy are ThermaSol sauna cabins?

Our ThermaSol cabin listings range from about 1,300 to 4,600 lb, so they need a level, solid base and planned freight delivery. Outdoor cabins usually sit on a concrete pad or an engineered foundation. Check each listing's dimensions and access needs before you order.

What electrical service do ThermaSol products need?

ThermaSol sauna heaters and steam generators need a dedicated circuit, most often 240V, sized to the unit's kW rating. A licensed electrician should confirm panel capacity before you order, especially if you are adding both a sauna and a steam shower to the same home.

How do I size a ThermaSol steam generator?

Generator size depends on the steam room's volume, ceiling height and wall materials, since stone and glass absorb more heat than tile over a waterproof board. Our ThermaSol generators run from 6 to 24 kW. Use our steam generator calculator, then confirm the choice with your installer.
