SaunaLife Wood-Fired Hot Tub | Model S4B/S4N

Engineered and crafted in the Northern Europe, this super-efficient hot tub heats in 1/3 of the time and consumes 50% less wood than other wood-fired hot tubs. The interior surface is easy to clean, and the exterior is crafted from thermally enhanced spruce for superior weather resistance and durability. It uses an ingenious self-cleaning corrugated stove with a secondary chamber that transfers heat from the smoke. Brilliantly, the air between the fiberglass lining and the wood exterior is super-heated to accelerate the heating process.
