The SaunaLife Model S6B Wood-Burning Hot Tub delivers high-performance, off-grid soaking with a bold black Thermo-Spruce exterior.
Designed to accommodate up to seven bathers, the S6B combines modern aesthetics with advanced wood-fired heating efficiency. Crafted from thermally enhanced spruce that lasts up to 2X longer than cedar, this outdoor hot tub offers superior weather resistance and durability.
At its core is a professional-grade 304 stainless steel dual-compartment wood-burning heater engineered to reduce wood consumption while dramatically improving heat transfer efficiency. The advanced stove system allows the S6B to heat 436 gallons of water from 40°F to 95°F in approximately 1.5–2 hours — significantly faster than traditional wood-fired hot tubs.
No electrical connections. No pumps. No complex systems. Just pure, efficient wood-fired performance with modern design appeal.
