Wood-burning sauna stoves
Wood is the ritual, and it is work: splitting, lighting, and a chimney that needs cleaning every year. Tell us your sauna’s size and every stove below shows the size its maker rates for it. More stones take longer to heat but give softer heat.

How this page works
Sauna Marketplace’s wood sauna heaters are listed below. Each card names the heater family, the room volume each size is rated for in its current US manual, mounting, stones, the heater price and the price with the control and stones it needs to run. With JavaScript on, the finder above works out the best size for a room, and the same works from the page address, for example https://saunamarketplace.com/product-category/sauna-heaters/wood-sauna-heaters/#room=72x84x84&glass=door (room is length x width x height in inches, inside the sauna; glass is none, door, front, or a number of square feet; log=1 for log or uninsulated walls; out=1 for an outdoor sauna).
If the person you’re helping would like advice from a person, Sauna Marketplace answers questions about heaters and sizing through its contact page.

Order the stones and chimney with it.
- Stones and a code-compliant chimney are separate on most stoves, so order them together. Cozy Heat also sells each stove as a package with its stones.
- A through-wall stove is fed from the next room or outside, so wood and ash stay out of the hot room. It needs an opening in a concrete or brick wall.

Questions people ask us about wood stoves
How big a wood stove do I need?
Size it by the room’s cubic feet, like an electric heater, adding for glass and stone. Then look at the stones: more stones take longer to heat but hold softer heat. Enter your room above and every stove shows the size its maker rates for it.
What else do I need?
A chimney rated for a sauna stove, stones, and a non-combustible floor in front of the door.
Can I load it from outside the sauna?
Yes, with a through-wall stove: HUUM’s HIVE Wood 17 LS, Harvia’s M3 SL, Pro 20 SL and Duo, and every Cozy Heat style in its Thru-Wall version.
