19 outdoor sauna kits here have a regular price under $10,000 on the maker's own site, from $4,485 to $9,083. Some were on sale for less on the day we read them. Where a maker sells several configurations, the figure is the cheapest.
Price the base, the delivery and the wiring run from your panel before you compare kit prices, since those land on the same bill. Narrow the list by seats and maker, then open each product page and read what the maker includes and what it leaves to you. The linked guides cover the site and the permits.
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.
