The Ultimate in Wood-Burning Hot Tub Luxury

The SaunaLife SOAK-Series Model S4B represents the pinnacle of wood-burning hot tub quality, efficiency, and luxury. Designed to deliver an unparalleled outdoor bathing experience, this hot tub is perfect for those who value relaxation and quality craftsmanship.

Ready for Your Hot Tub Party

Arriving fully assembled, the Model S4B wood-fired hot tub is easy to set up and ready for use right out of the box. The ergonomically shaped fiberglass tub comfortably seats up to six people, making it ideal for gatherings with friends and family. The interior is designed for easy cleaning, while the exterior is crafted from thermally enhanced spruce, offering superior weather resistance and durability.

Engineered for Efficiency and Performance

Crafted in Northern Europe, the Model S4B is engineered for maximum efficiency. This super-efficient hot tub heats in just a third of the time compared to traditional wood-fired hot tubs, with no need for an electrical connection. At its heart is an ingenious self-cleaning corrugated stove featuring a secondary chamber that transfers heat from the smoke, reducing wood consumption by up to 50%. The air between the fiberglass lining and the wood exterior is super-heated to accelerate the heating process. The stove draws cooler water through a lower channel and redistributes it through an upper channel, ensuring even temperature distribution.

Start Enjoying Sooner

With its efficient wood stove, the Model S4B heats 304 gallons of water from 40°F (5°C) to 95°F (35°C) in just 1.5 to 2 hours, making it the fastest-heating wood-burning hot tub available. Enjoy the luxury and relaxation of your own backyard wood-burning hot tub from SaunaLife.
