"Adjusted Volume" Is What Really Matters

When buying a sauna heater, you technically shouldn't use seating capacity.

Your sauna's adjusted volume is what dictates how powerful of a heater you need (measured in kilowatts, or kW).

Saunas with a lower adjusted volume need a less powerful heater (i.e. a low-kilowatt heater). Saunas with a bigger adjusted volume require a more powerful heater (i.e. a high-kW heater).

So what is your sauna's adjusted volume? It 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), typically a +20% adjustment
