Built with high-grade, weather-resistant Thermo-Spruce wood, this soothing soaking tub offers an authentic off-grid experience for up to 7 people, eliminating the need for complex electrical wiring or high utility costs. The Model S6B features an integrated high-efficiency wood stove that enables a tranquil, therapeutic soak that promotes muscle recovery and stress relief. Invest in your well-being with a wood-fired hot tub that blends traditional heating methods with modern ergonomic design for the ultimate rejuvenating escape.
Ready for your hot tub party
The Model S6B arrives completely assembled and is easy to set up. Its ergonomically shaped fiberglass tub is a comfortable place for up to 7 people. The interior surface is easy to clean, and the exterior is crafted from thermally enhanced spruce for superior weather resistance and durability.
Engineered for efficiency and performance
Engineered and crafted in the Northers Europe, this super-efficient hot tub heats in 1/3 of the time as traditional wood-fired hot tubs. No electrical connection is required. At the heart of the Model S6B is its ingenious self-cleaning corrugated stove with a secondary chamber that transfers heat from the smoke – reducing wood consumption up to 50% compared with other hot tubs. Brilliantly, the air between the fiberglass lining and the wood exterior is super-heated to accelerate the heating process. The stove is cleverly engineered to draw cooler water through a lower channel and redistribute it though an upper channel to equalize the temperature.
Start enjoying sooner
This incredibly efficient wood stove will heat 304 gallons of water from 40°F (5°C) to 95°F (35°C) in 1.5 to 2 hours, the fastest-heating wood-burning hot tub available.
Relax with the luxury of the SaunaLife Model S6B Tub and elevate every soak into a serene, spa-like escape right in your own backyard.
