Description

The SaunaLife Model S6B is a premium wood-fired hot tub engineered for rapid heating and exceptional efficiency. This fully assembled unit accommodates up to 7 people in an ergonomically designed fiberglass basin with easy-to-maintain interior surfaces. Constructed from thermally enhanced spruce, the exterior withstands harsh weather while the innovative self-cleaning corrugated stove with secondary heat chamber reduces wood consumption by up to 50%. The ingenious dual-channel water circulation system equalizes temperature distribution, while superheated air between the fiberglass and wood exterior accelerates the heating process. Requiring no electrical connection, the Model S6B heats 436 gallons from 40°F to 95°F in just 1.5 to 2 hours—the fastest performance in its class. Engineered and crafted in Northern Europe, this is the ultimate choice for those seeking luxury, efficiency, and reliability in a wood-burning hot tub.
