11 kits here are rated by their makers for two people. 8 of the 11 show a price on the maker's own site; their regular prices run from $4,299 to $8,397, and some were on sale for less on the day we read them. Where a maker sells several configurations, the figure is the cheapest.
Measure the space the sauna will stand in before you read the list, whether that is a corner of the basement or a patch of the yard. Then set the price filter, open each product page, and read the maker's own figures for the footprint and the bench length. A pair who like to lie down may want to read the larger kits too.
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.
