From our reviews
These are the saunas and gear we'd buy with our own money this month. Each card says who it suits.
Upgrade pick
“Built in-house from cedar, this five-seat cube is a sauna you buy once and pass down.”
If budget were no object, we'd choose the Cube, and it's our anchor pick even at its price. Nootka builds it in-house in British Columbia from inch-and-a-half Western Red Cedar. The room seats five, and Nootka says it reaches 194°F in 30 to 45 minutes. Its LTE controller lets you start preheating from your phone on the drive home.
Our pick
“This cabin runs nine far-infrared heaters off a standard wall plug.”
For most homes, the Solstice is our pick. It plugs into a standard 120V outlet, so no electrician stands between you and your first session, and its nine far-infrared heaters carry third-party-verified low EMF. It's sized for two. Buy it if you want the health habit without the renovation. By our pricing it undercuts the full-spectrum flagships by thousands.
Pick for renters
“Renters can fold this infrared blanket under a bed after each session.”
HigherDOSE's blanket shows you don't need a backyard for heat therapy. The company says it reaches 175°F with low-EMF heating and non-toxic materials. It folds away and costs a tenth of a cabin. You'll need a hot room for löyly and 90°C air, and the blanket still gets you to a heavy sweat several times a week. The cohort studies found the benefit grew with frequency. It's our pick for a renter's first heat setup.

Nootka's cedar barrel runs in hotel courtyards from Fairmont to Four Seasons. We checked what it's made of and what it costs all-in, then compared it with the cheaper kits.
“Most barrels arrive as a half-ton of flat-pack you assemble yourself. For buyers in its delivery range, Nootka brings the sauna by truck and builds it on site.”

Fatal heart disease
−50%
In the Finnish KIHD cohort, men who used a sauna 4–7 times a week had half the fatal cardiovascular events of once-a-week bathers over about 21 years of follow-up.
The fix: Buy the sauna you'll step into on most days, because this result comes from men who bathed four to seven times a week.

“The cohort research found its strongest associations at 4–7 sessions a week, and that pace is easier to keep when the sauna is down the hall.”

An indoor sauna is easier to stick with, since you reach it without boots or a walk through the snow. Set it up so the protocol happens by default.

Gentle heat for heart patients
140°F
In a randomized trial of 149 heart-failure patients, two weeks of Waon therapy (15 minutes of far-infrared at 60°C) raised walking distance. BNP, the heart-strain marker the trial set out to lower, fell no more than with standard care.
The fix: Choose infrared if you plan near-daily sessions, since its lower air temperature makes them easy to tolerate.
