Can you put a sauna kit indoors, in a basement or garage?
Yes, if the room allows it: 20 kits here are listed by their makers for indoor use. Whether your basement or garage works depends on its floor, ceiling, ventilation and wiring, which the linked guides take in turn.
Read the linked guides on floors, ventilation and wiring before you shortlist, because whether your basement or garage works depends on the room itself, which no listing can see. Use the picks and the maker filter to narrow the kits, then bring a licensed electrician in before you order anything electrical.
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.
As an Amazon Associate we earn from qualifying purchases. Some links on this page are paid: if you buy after following one, the retailer pays Saunakivi (IPORA LLC) a commission. It costs you nothing extra, and it never changes the specifications we list.

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.
