Sizing 101
How to size your heater
Sauna heaters are matched to room volume. Measure your sauna interior length by width by 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.

Buyer's Guide
How to Choose a Electric Sauna Heater
A quick guide to picking the right option from our Electric Sauna Heaters collection.
Match the output to your room
Heater size (kW) must match your sauna's cubic volume; glass and uninsulated surfaces raise the output needed. Our team can confirm the right size.
Electric vs wood-burning
Electric heaters offer fast, controllable heat; wood-burning heaters deliver the ambiance of a live fire. Choose based on power access and preference.
Controls
Decide between built-in controls and a separate digital or Wi-Fi controller for scheduling and app control.
Stones and accessories
All traditional heaters use sauna stones; confirm whether stones are included or added separately.
