Sizing 101
How to size your heater
Sauna heaters are matched to room volume. Measure your sauna's interior length × width × height to get cubic feet, then choose a heater whose rated range covers it (roughly 1 kW per 45–50 cu ft). Most electric heaters also need a compatible control unit and sauna stones, sold separately. Not sure? Our specialists will size it with you.
