Model S6B Wood-Burning Hot Tub
Make room for outdoor soaking with the SaunaLife S6B. Its round fiberglass interior accommodates up to seven bathers, surrounded by black-painted Thermo-Spruce and warmed by a 304 stainless steel wood-burning heater.
No electrical hookup is required. Matching steps, an insulated cover, and a stainless steel chimney with cap are included.
Wood-Fired Warmth for Shared Outdoor Soaking
Room for Up to Seven
A contoured fiberglass interior and 436-gallon capacity create a spacious setting for quiet evenings or time with guests.
Black Thermo-Spruce
The thermally modified spruce surround brings a bold black finish to your outdoor space. Regular exterior care helps maintain its appearance.
Stainless Steel Wood Heater
The 304 stainless steel heater uses two heat-transfer compartments to warm the water without an electric heating connection.
Cover and Steps Included
Matching steps provide access, while the folding insulated cover helps limit heat loss and keep debris out between uses.
The S6B suits buyers who enjoy tending a wood fire and planning their soak ahead. It is a soaking tub without powered massage jets or app-based temperature control.
Allow Time for the Fire and the Water
SaunaLife publishes a heating reference of approximately 1.5–2 hours for 436 gallons from about 40°F to 95°F. Actual timing depends on starting water temperature, weather, firewood, fire management, and cover use.
Heating is managed by tending the fire. Use a suitable water thermometer and follow the supplied manual; the reference time is not a guaranteed ready-to-soak schedule.

What’s Included
- Factory-assembled S6B hot tub with black Thermo-Spruce surround and fiberglass interior
- 304 stainless steel wood-burning heater
- Polished stainless steel chimney and chimney cap
- Matching Thermo-Spruce steps
- Folding insulated cover with steel-reinforced foam core and marine-grade vinyl exterior
- Drainage system with tap
- Manufacturer setup and operating instructions
Site preparation, unloading assistance beyond the carrier’s curbside service, final placement, firewood, and water supply are the buyer’s responsibility. Unpacking and final setup are still required.
Plan the Base, Access, and Fire Clearances
- Support: Provide a level base designed for the tub, water, and occupants. At 436 gallons, the water alone weighs approximately 3,636 lb. Have a qualified professional assess any deck or elevated structure.
- Outdoor placement: The current manual calls for at least 13 feet between the tub and any building. Check the complete instructions and applicable local requirements before selecting a location.
- Delivery access: Measure the route from the curbside to the base, including gates, turns, slopes, and overhead obstructions. Plan handling equipment before the delivery appointment.
- Water and drainage: Arrange hose access for filling and an appropriate route for draining through the supplied tap.
- Before firing: Fill to the manual’s specified water level before lighting the heater. Never leave the fire unattended, and do not drain until the embers are fully extinguished.
Care and Cold-Weather Use
Follow the S6B manual for cleaning after use, water changes, and exterior wood care. Use compatible non-abrasive cleaners and maintain the wood finish as directed.
Prepare the tub, stove, and drain valve for freezing weather exactly as directed in the manual. The insulated cover does not provide freeze protection.

Frequently Asked Questions
Does the S6B require electricity?
No. The supplied wood-burning heating system does not require an electrical hookup. Heating is managed by tending the fire.
How long does it take to heat the water?
SaunaLife publishes approximately 1.5–2 hours to heat 436 gallons from about 40°F to 95°F. Weather, starting water temperature, wood quality, fire management, and cover use affect actual timing.
Does the tub arrive ready to use?
The tub arrives factory-assembled, but it still needs safe unpacking, final placement, setup, and filling according to the manual. Curbside delivery does not include moving it into your backyard.
What length of firewood should I use?
The current S6B manual specifies dry firewood no longer than 13 inches. Follow the instructions supplied with your tub before lighting the heater.
Can it stay filled in freezing weather?
The manual requires draining the tub and stove after use in winter and leaving the drain valve open to prevent freezing. Wait until all fire and embers are extinguished before draining.
