16 kits here are rated by their makers for four people. 14 of the 16 show a price on the maker's own site; their regular prices run from $5,184 to $10,080, and some were on sale for less on the day we read them. Where a maker sells several configurations, the figure is the cheapest.
Look at the most seats pick first, then filter by maker and price on the maker's site to see which other kits the makers rate for the same count. Every seat count comes from the maker's own literature, so plan the bench layout with your own tape measure. Decide whether people will sit or lie down before you settle on a count.
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.
