Description
The SaunaLife Model S4N delivers premium wood-fired soaking in a pre-assembled, ready-to-use package. This six-person fiberglass tub features thermally enhanced spruce construction for exceptional durability and weather resistance. Engineered in Northern Europe, the Model S4N heats 304 gallons from 40°F to 95°F in just 1.5–2 hours—the fastest wood-burning hot tub available. Its innovative self-cleaning corrugated stove with secondary heat-exchange chamber reduces wood consumption by up to 50% while requiring zero electrical connection. Superheated air between the fiberglass and wood exterior accelerates heating efficiency, while dual-channel water circulation equalizes temperature throughout. The smooth interior surface resists buildup and cleans easily, making maintenance straightforward. Ideal for backyard entertaining and year-round relaxation.
