* based on typical sauna sizes (your sauna may differ) - calculate how many kW your sauna needs

How do I know how many kilowatts (kW) my sauna heater needs?

Short answer: Click this button & we'll tell you → Calculate kW Needed

Long answer: It all comes down to your sauna's adjusted volume, which is:

the volume of the interior of your sauna (width x depth x height), plus
an adjustment for "cold surfaces" in your sauna (i.e. glass, tile & stone)

The bigger your sauna is and the more "cold surfaces" (i.e. windows, tiled walls, etc.) the interior has, the more kW power your heater needs.

If this sounds a little bit tricky, don't worry... we've got you covered! Just use our handy-dandy CALCULATOR to tell us about your sauna. We'll tell you exactly how many kilowatts (kW) your heater should have and give you our top recommendations of heaters for your sauna.

Final note: A heater's wattage (kW) has nothing to do with how hot it will get your sauna. Virtually all sauna heaters are capable of temperatures well above what you'll want. The heater's wattage determines how large of a sauna it is capable of heating.
