    Unleash the Power of Thermo-Spruce in your Wood-Fired Hot Tub

    SaunaLife’s Model S4B uses Thermo-Spruce’s resilience, ensuring that your hot tub lasts up to 2X longer than those made of Cedar. The Thermo-Spruce surround combines superior weather resistance and durability, providing an exceptional, eco-friendly hot tub experience. Also available in natural wood that’s been thermally modified to outlast cedar.

    Efficiency and Performance – Beyond the Conventional

    The Model S4B, crafted with Northern European precision, represents a breakthrough in wood-fired hot tub efficiency. Uniquely designed to heat three times faster than traditional models, it does not require any electricity, making it both eco-friendly and cost-effective. The Model S4B features a self-cleaning corrugated stove with dual chambers that efficiently transfer heat and reduce wood consumption by up to 50%.

    Soak in Bliss Sooner with Rapid Response Heat-up Time

    A uniquely efficient wood stove heats the spacious 304-gallon water capacity in just 1.5 to 2 hours. This is the fastest heat-up time among wood-burning hot tubs on the market. With Model S4B, you can start soaking in bliss sooner, anytime you wish.

    Ready to turn your backyard into a personal retreat? Add the Model S4B wood-fired hot tub to your cart and immerse yourself in luxury and tranquillity.

     

    The Safe Choice: AISI 304 Stainless Steel Stoves

    These SOAK series hot tubs from SaunaLife feature premium AISI 304 stainless steel stoves, offering durability and peace of mind. Unlike aluminum alternatives, our stainless steel stoves resist chemical cleaning agents, withstand accidental dry heating, and maintain their elegant appearance for years. Engineered for maximum efficiency, these stoves channel 100% of heat energy directly to the water, heating your hot tub in just 1.5-2 hours, debunking the myth that aluminum heats faster.

    More importantly, stainless steel eliminates the health concerns associated with aluminum exposure, which has been linked to decreased kidney function, nerve problems, muscle weakness, and bone diseases. Choose DeLux for a safer, more reliable, and longer-lasting hot tub experience that supports your health and relaxation goals.

      PLAN THE WHOLE SAUNA

      The room and heater still have to work as one system.

      Start with the room dimensions, then account for glass, masonry, insulation, ceiling height, required clearances, and available electrical service. That is how we move from a product that looks right to a sauna that heats evenly and comfortably.

      Compare sauna heaters

      See electric sauna heaters by output, stone mass, control style, and installation type. Size from adjusted room volume, not floor dimensions alone.
