Barrel Outdoor Sauna - 8 Person

An 8-seat thermowood barrel at $6,899, third-cheapest barrel per seat at $862, with an 8 kW heater and a 1-year warranty.

Only the two tied Almost Heaven barrels, Lewisburg and Grandview at $795, cost less per seat. The shell is the same 92.5 by 72.8 by 76.5 inches and 1,150 pounds the data gives for the 6-seat porch barrel, which costs $400 less. So the extra two seats get you the 8 kW heater and no more room: 5.8 square feet per seat against 9.4 typical.

Treat 8 as a maximum and plan for five or six. Lewisburg costs $541 less with the same heater and a lifetime warranty, and the Redwood Garden, a square 8-seater, is $1,800 more. This one suits a buyer who wants thermowood and the lowest price per seat. No porch is recorded. Redwood Outdoors is the only store.
