How much does a sauna heater cost?
$1,300 to $3,295 at regular price, going by the 7 of 42 heaters and stoves here whose makers show a price on their own sites. Where a maker sells several configurations, the figure is the cheapest. So few show a price that this range describes those 7, not heaters in general.
Start with the price filter, set to where you are comfortable, then add the stated warranty filter and compare what remains. Each pick leads on a figure the maker publishes on its own site. Before that price means much on its own, add up whatever else you will buy alongside it and a licensed electrician's time, and read the linked guide on wood versus electric.
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.

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.
