The numbers.
Why this model.
The SaunaLife Model S4N is an authentic Scandinavian wood-burning hot tub — heated by firewood, no electrical hookup required. Built from Natural Thermo-Spruce with a fully assembled fiberglass tub interior, the S4N is the answer for cabin, rural, off-grid, or backyard buyers who want premium hot-tub therapy without the electrical infrastructure of a traditional spa.
Authentic Wood-Burning Heat
The integrated wood-burning stove heats 304 gallons of water from 40°F to 95°F in 1.5–2 hours. No electrical service required. Traditional Scandinavian hot tub experience — the smell of wood smoke, the heat of an open fire, the deep relaxation of a hot soak. Replace electricity with firewood.
Up to 6 Person Capacity
Exterior diameter: 79" with 37" walls. Interior bench seating accommodates up to 6 people for shared sessions, or stretch out solo. Substantial enough for daily family use.
Thermo-Spruce Construction (2× Cedar Lifespan)
Thermowood-treated Spruce lasts 2× longer than cedar outdoors. Natural finish weathers gracefully. Built for daily-use construction and exposure to the elements.
Fully Assembled — Plug-and-Play (Without the Plug)
Ships fully assembled. Position on level ground (concrete pad, gravel, or deck), fill, light fire, soak. Includes steps for entry and an insulated cover for heat retention between sessions.
Unique in the US DTC Market
Most US direct-to-consumer wellness brands skip wood-burning hot tubs entirely — too operational, too rural-focused, too "non-tech." SWS carries it because some buyers want the real Scandinavian experience: firewood, smoke, fire, and water. If you're building a cabin or rural retreat, this is the centerpiece.
