Soak-Series Home Wood-Burning Hot Tub, Up to 6 Persons

Introducing the SaunaLife SOAK-Series Model S4B Outdoor Wood-Burning Hot Tub, a pinnacle of quality, efficiency, and luxury for your relaxation needs.

Designed for Your Enjoyment

Experience the epitome of hot tub indulgence with the Model S4B. This wood-fired hot tub is delivered fully assembled and is effortlessly set up for your convenience. Crafted with a spacious fiberglass tub, comfortably accommodating up to 6 individuals, it promises relaxation in style. Cleaning is a breeze thanks to its smooth interior surface, while its thermally enhanced spruce exterior ensures unparalleled weather resistance and durability.

Efficiency Redefined

Hailing from Northern Europe, the Model S4B is engineered for peak efficiency and performance. Unlike traditional wood-fired tubs, it heats up in a fraction of the time, without the need for any electrical connections. Central to its design is the innovative self-cleaning corrugated stove, featuring a secondary chamber that efficiently transfers heat from smoke, reducing wood consumption by up to 50%. Additionally, the clever construction facilitates rapid heating by superheating the air between the fiberglass lining and wood exterior. This stove ingeniously maintains temperature equilibrium by drawing cooler water through a lower channel and evenly redistributing it via an upper channel.

Quick Enjoyment, Guaranteed

With the Model S4B, your relaxation time is maximized. This efficient wood stove swiftly heats 304 gallons of water from a chilly 40°F (5°C) to a soothing 95°F (35°C) in just 1.5 to 2 hours—setting the standard for rapid heating among wood-burning hot tubs.

Embrace luxury and leisure with your loved ones in the comfort of your own backyard, courtesy of the SaunaLife Model S4N outdoor wood-burning hot tub.
