Immerse yourself in the epitome of wood-burning hot tub luxury with the SaunaLife SOAK-Series Model S4N Outdoor Wood-Burning Hot Tub. Designed for your hot tub party needs, this model effortlessly combines quality, efficiency, and comfort to redefine your relaxation experience.

Ready for Your Hot Tub Party

The Model S4N arrives fully assembled, simplifying the setup process for your convenience. Its ergonomically shaped fiberglass tub offers a comfortable retreat for up to 6 people. The interior surface ensures easy cleaning, while the exterior, crafted from thermally enhanced spruce, guarantees superior weather resistance and durability.

Engineered for Efficiency and Performance

Crafted and engineered in Northern Europe, the Model S4N stands out with its exceptional efficiency and performance. Unlike traditional wood-fired hot tubs, this model heats in 1/3 of the time without requiring any electrical connection. At its core is a self-cleaning corrugated stove with a secondary chamber that maximizes heat transfer from the smoke, reducing wood consumption by up to 50%. The innovative design super-heats the air between the fiberglass lining and the wood exterior, accelerating the heating process. The stove intelligently draws cooler water through a lower channel and redistributes it through an upper channel, ensuring temperature equalization.

Start Enjoying Sooner

Experience the fastest heating among wood-burning hot tubs. This incredibly efficient wood stove can heat 304 gallons of water from 40°F (5°C) to 95°F (35°C) in just 1.5 to 2 hours.
