Premium Wood-Burning Hot Tub for Outdoor Soaking
The SaunaLife Model S6B is a fully assembled, outdoor wood-burning hot tub designed for up to 7 bathers. It holds 436 gallons of water and heats from 40°F to 95°F in approximately 1.5–2 hours using a dual-chamber 304 stainless steel stove that reduces wood consumption by up to 50%. Crafted in Northern Europe and finished in durable black Thermo-Spruce, the Model S6B requires no electricity, making it ideal for off-grid properties, cabins, and backyard wellness spaces.
Why Homeowners Choose the Model S6B
🔥 Rapid Wood-Fired Heating (No Power Required)
- Heats 436 gallons in 1.5–2 hours
- No electrical hookup needed
- Burns standard firewood (up to 16")
- Maximum temperature: 106°F
At the heart of the system is a corrugated 304 stainless steel stove engineered with:
- Dual heat compartments
- Secondary chamber that captures heat from smoke
- Up to 50% lower wood consumption than standard wood-fired tubs
- Integrated water channel system for even temperature distribution
Cooler water is drawn in through a lower channel and redistributed through an upper channel to maintain consistent soaking temperatures.

🌲 Thermo-Spruce Construction (Lasts Up to 2X Longer Than Cedar)
The Model S6B uses thermally modified spruce—known as Thermo-Spruce—for enhanced durability and thermal performance.
Benefits of Thermo-Spruce:
- Superior R-value for heat retention
- Exceptional dimensional stability in wet conditions
- Increased resistance to decay
- Longer lifespan than traditional cedar
- Eco-friendly and sustainably sourced
The 1.65" thick surround is painted black for modern aesthetics and enhanced weather protection.
🛁 Spacious, Ergonomic Soaking for Up to 7 People
Designed for comfortable group bathing, the Model S6B includes:
- Thick dark grey contoured fiberglass interior
- Smooth, easy-to-clean surface
- 436-gallon capacity
- Integrated drainage tap
- Reinforced structure for long-term outdoor use
Ideal for:
- Backyard entertaining
- Family wellness routines

How the Dual-Chamber Stove System Works
The Model S6B stove is engineered for high efficiency:
- Firewood burns in the primary chamber.
- Heat and smoke pass into a secondary chamber.
- Residual heat is captured and transferred into the water.
- Corrugated steel increases surface area for maximum heat transfer.
- The water circulation channel system equalizes temperature naturally.
This design reduces wasted heat while accelerating warm-up time.
