Cayman 400D7

A 4-seat hemlock cabin at $5,690 with an 8 kW heater and a 10-year warranty, third-cheapest per seat among the 22 cabins.

Cayman is one of nine hemlock models in our data: four from SunRay, three from Peak Saunas and two from Golden Designs. At $1,422 per seat it comes in 24 percent under the cabin median of $1,868. It has an 8 kW heater, which is 2 kW per seat, more than the 1.5 typical here, in a compact 69 by 72 inch footprint, 85 inches tall.

The warranty is the standout. SunRay states 10 years, where the data shows 7 years on its Denali and Seneca, 5 from SaunaLife and Dundalk, 3 from Sweat Kingdom and 1 from Redwood Outdoors, with Almost Heaven and Peak Saunas stating a lifetime warranty. The kit weighs 810 pounds, light for a cabin. Topture is the one store we list, so there is no price to compare. The red cedar Denali is $400 cheaper with a 6 kW heater.
