The SaunaLife SOAK-Series Model S4N is a premium wood-fired hot tub designed for elevated outdoor bathing. Crafted with high-performance materials and engineered for exceptional efficiency, it delivers a refined, off-grid soaking experience without the need for electricity.
Built with a durable Thermo-Spruce exterior—lasting up to twice as long as cedar—the Model S4N offers superior thermal resistance, weather durability, and long-term stability in water environments. Its spacious, ergonomically shaped fiberglass interior comfortably accommodates up to six bathers and holds over 304 gallons of water, creating an immersive and relaxing soak.
At its core, a high-efficiency wood-burning stove made from 304 stainless steel uses a dual-chamber combustion system to maximize heat output while reducing wood consumption by up to 50%. The intelligent circulation design draws cooler water from the bottom and redistributes heated water through the upper channel, ensuring consistent temperatures throughout the tub. Additional heat is captured in the air space between the fiberglass lining and the wood surround, accelerating the overall heating process.
Thanks to this advanced system, the Model S4N can heat water from 40°F (5°C) to 95°F (35°C) in approximately 1.5 to 2 hours.
The hot tub arrives fully assembled and ready for installation, requiring no electrical connection. Designed by SaunaLife and handcrafted in Northern Europe, the Model S4N combines traditional wood-fired bathing with modern engineering.
