Sauna heater sizing guide
Measure your sauna room in feet and multiply length × width × height to get the volume in cubic feet. A 6 × 6 × 7 ft room, for example, is 252 cubic feet. Then match it to the heater power below.
| Heater power | Typical sauna size |
|---|---|
| 3.5 to 4.5 kW | 106 to 248 ft³ |
| 6 kW | 177 to 318 ft³ |
| 7.5 to 8 kW | 248 to 425 ft³ |
| 9 kW | 283 to 460 ft³ |
| 10.5 kW | 354 to 566 ft³ |
| 12 kW | 424 to 636 ft³ |
| 15 kW | 530 to 813 ft³ |
| 18 kW | 636 to 989 ft³ |
Ranges are the manufacturers’ published ratings for the HUUM and Harvia heaters we carry; other brands are similar but check each model. Glass walls, stone or tile and uninsulated log walls need more power, so size up. Not sure? Send us your sauna size and a specialist will recommend the right heater.

Electric sauna heater questions
What size sauna heater do I need?
Multiply your room’s length, width and height in feet to get cubic feet, then use the sizing guide on this page. A 6 × 6 × 7 ft room (252 ft³) suits a 6 to 7.5 kW heater. Glass, stone and log walls need more power.
Do electric sauna heaters need an electrician?
Most electric sauna heaters are hardwired on a dedicated 240 V circuit and should be installed by a licensed electrician. We confirm the electrical requirements for your heater before you order.
Can I control my sauna heater from my phone?
Yes, with a compatible controller. HUUM heaters pair with the UKU controller for Wi-Fi control, so you can start your sauna from anywhere.
Do I need sauna stones?
Yes. Sauna heaters and stoves need stones to store and release heat and create steam. We can include the right amount of stones for your heater in your quote.
How much does heater shipping cost?
Most heaters and stoves ship across Canada and the US for $299. Larger stoves with 10 or more boxes of stones ship for $499.
