Which Size Should I Choose?

Selecting the right sauna heater size depends on the total cubic footage of your sauna room. Proper sizing ensures efficient heating, consistent temperatures, and long‑term performance.

  • 12.0kW Heater – Ideal for sauna rooms up to 980 cubic feet
  • 15.0kW Heater – Best for medium‑to‑large sauna rooms up to 1,460 cubic feet
  • 18.0kW Heater – Designed for large sauna rooms up to 1,680 cubic feet

To calculate your sauna room size, multiply the length × width × height of the interior space. Always round up to the nearest size if your sauna is close to the maximum capacity.

Perfect for Commercial Use

I run a wellness studio, and we upgraded to the 15.0kW Scandia Ultra for our larger sauna. It’s been a game‑changer. The heater handles back‑to‑back sessions without struggling, and our clients always comment on how consistent the heat feels. Installation was straightforward with our electrician, and the external controls make it easy for staff to operate. Couldn’t be happier.
