The right sauna depends on your space and budget, so we picked a winner in each category instead of crowning one. Every pick comes from our full rankings, which score brands on value, reviews, warranty and years in business.
Best overall
$6,799–$14,000Heat score 86
Clearlight has the highest heat score of any brand we track. It backs its indoor saunas with a limited lifetime residential warranty that includes heaters and controls, the most generous terms we found, and has been building infrared saunas since 1997. Expect premium prices and long lead times.
Most trusted by buyers
$2,500–$12,000Heat score 82
Sunlighten has more than 4,000 Trustpilot reviews averaging 4.7 stars, by far the largest review base in the category, and publishes clinical research on its heaters. Pricing is quote-based and sits at the top of the market.
Best value with red light
$4,750–$16,750Heat score 79
Every Peak model ships with a built-in red light panel, app control and a 7-year warranty, for less than comparable premium brands. It's a young company, so the review base is still small.
Most experienced
$3,500–$8,400Heat score 82
Health Mate has made infrared saunas since 1979, the longest run of any brand we score, and puts a lifetime warranty on its heaters. Designs are more traditional than newer brands.
Best budget infrared cabin
$1,000–$12,999Heat score 68
JNH sells infrared cabins starting around $1,000 and has been in business since 1989. The trade-off is a short 1-2 year warranty on most models and a lower top temperature.
Best American-made outdoor barrel
$5,145–$9,645Heat score 58
Sweat Kingdom hand-builds Western red cedar barrels in Idaho with your choice of Harvia or HUUM heater. Independent reviews are thin, so read the brand's own reviews before buying.
Best portable sauna
$2,300Heat score 64
Relax Sauna's pod reaches 170°F, packs away when you're done and is HSA/FSA eligible. The company hasn't published a warranty or EMF readings, which pulls its score down.
Best sauna tent
$2,187Heat score 54
North Shore's Minnesota-made wood-fired tent sits six people and gets past 200°F in under half an hour. It's the closest thing to a traditional Finnish sauna you can pack in a car.
Cheapest way to try infrared
$349Heat score 50
At $349, MiHIGH's blanket lets you test whether you like infrared heat before spending thousands. Expect a 12-month warranty and far infrared only.
We started with every US sauna brand that has an affiliate program, gathered its prices, warranty terms, founding year and public review scores, then scored each one the same way. Where a brand doesn't publish something, it scores low on that measure until it does. Brands can buy a labeled sponsored spot at the top of the page, but they can't buy a pick or a score. Read the full method.
Start with What's the best sauna?, which walks through infrared versus traditional, indoor versus outdoor, and what each costs to run.
