Adj. VolumeAdjusted Sauna Volume

This column shows the adjusted sauna volume range for which each sauna heater is rated.

"Adjusted sauna volume" is the volume (i.e. Width  x  Depth  x  Height) of the interior of the sauna PLUS an adjustment for cold surfaces in the sauna (i.e. glass, tile, stone, etc. — but not including the floor). This adjustment is typically around +20% but can be more (for example, if your sauna has multiple large windows).

Want to verify your sauna's adjusted volume?  Use this 20-second CALCULATOR to make sure the heater you buy has the correct power (measured in kilowatts, or kW).

Sauna SizeMaximum Sauna Size

This column provides a quick-reference estimate of the maximum sauna capacity (i.e. 3-person sauna, 4-person sauna, etc.) for which each sauna heater is rated.

Again, this is only an estimate based on average sauna sizes, layouts & interior cold surfaces. Your sauna may differ. We strongly recommend taking 20 seconds to verify your sauna's adjusted volume (which is much more precise) to make sure the heater you buy has enough power (measured in kilowatts, or kW).
