The Ridge

The second-dearest 2-seat sauna in our data at $7,145, or $3,572 a seat, with a 6 kW heater and a 3-year warranty.

Ridge is the ninth-dearest model per seat of all 85, 133 percent above the median of $1,532. It is a red cedar kit, 59.25 by 59.5 inches and 89.5 tall, about 24.5 square feet. The 6 kW heater is 3 kW per seat, double the typical 1.5.

The sister Summit is $200 cheaper with 8 kW, in a cabin shape, so on the fields we track the Ridge has no edge. The Almost Heaven Salem seats two in red cedar for $3,108 less and states a lifetime warranty, against 3 years here. The SunRay Bristow is $2,155 less with 10 years. The data records no shape, weight or porch for the Ridge. Sweat Kingdom is the only store we list. Choose it only if you have seen it and prefer it.
