Wood-burning sauna stoves: which room size is each rated for?

Every one of the 13 wood-burning stoves here has a room size its maker rates it for, quoted on each product page and ranked in the picks. 6 of the 13 show a price on the maker's own site; their regular prices run from $2,395 to $3,295. Where a maker sells several configurations, the figure is the cheapest.

Take your room's measurements first, then read the room size each maker states for its stove, in the picks and on every product page, and keep only what brackets your figure. Save where to buy and stated warranty for when the shortlist is short. Chimney and clearances belong with your installer, and the linked guides cover sizing and ventilation.

Picks by the numbers

Each pick is the product that comes first on one figure its maker publishes, with the next ones on that figure after it. Choosing which figures to rank by is our editorial choice; the order on each is the makers' own numbers. None is a judgement of quality, we have not tested these products, and whether we earn a commission on a product never decides a pick.

    • No price on the maker's site

Prices are the price each maker's own site showed in US dollars on the date shown; the seller's page has the current price. Warranties and safety listings are the makers' own statements, cited on each product page. A price starting 'From' is the cheapest configuration a maker offers, which may leave out the heater or options. Every product here is sold by its maker on the maker's own site. Where a product page carries a paid link (to Amazon or another approved retailer), Saunakivi may earn a commission; no sort order or filter favours those products. We have not tested these products.
