SaunaLife Model S4N 6-Person Home Wood-Burning Hot Tub

The SaunaLife SOAK-Series Model S4N is a premium wood-fired outdoor hot tub designed to deliver an authentic, luxurious soaking experience with exceptional heating efficiency and handcrafted Northern European craftsmanship. Combining modern comfort with traditional wood-fired performance, the Model S4N creates a relaxing outdoor retreat ideal for entertaining, recovery, or year-round backyard wellness.

Constructed from durable Thermo-Spruce, the Model S4N offers superior weather resistance, dimensional stability, and thermal performance compared to traditional cedar hot tubs. The spacious fiberglass-lined interior comfortably accommodates up to six bathers while providing a smooth, ergonomic soaking environment that is both comfortable and easy to maintain.

At the heart of the system is an advanced 304 stainless steel wood-burning heater engineered for rapid heat-up performance and improved fuel efficiency. Unlike traditional wood-fired tubs, the Model S4N utilizes a dual-chamber heating system that maximizes heat transfer while reducing wood consumption. The result is a faster, more efficient heating experience capable of warming over 300 gallons of water in as little as 1.5 to 2 hours without requiring electricity.

Delivered fully assembled and designed for simple outdoor setup, the Model S4N combines eco-friendly operation, Scandinavian-inspired design, and luxury-level comfort into one beautifully crafted outdoor hot tub.
