SaunaLife Soak Series Model S4N Home Wood-Burning Hot Tub, Natural, Up to 6 Persons

Create a refined Nordic-inspired retreat at home with the SaunaLife Model S4N, a 6-person wood-fired hot tub that pairs natural Thermo-Spruce craftsmanship with efficient off-grid heating and effortless outdoor relaxation.

SaunaLife Model S4N Wood-Fired Hot Tub – 6-Person Nordic Outdoor Soaking Tub

Bring the tradition of Scandinavian outdoor bathing into your own backyard with the SaunaLife Model S4N Wood-Fired Hot Tub. Designed for up to six people, the S4N combines premium natural materials, thoughtful ergonomic design, and efficient wood-fired heating to create a distinctive outdoor soaking experience.

Whether incorporated into a dedicated home wellness space, positioned alongside an outdoor sauna, or used as a centerpiece for your backyard, the S4N offers a beautiful alternative to conventional electrically heated hot tubs.

Scandinavian Design with Thermo-Spruce Construction

The Model S4N features an exterior crafted from thermally modified Thermo-Spruce, selected for its durability, weather resistance, and natural Scandinavian appearance. The warm wood finish gives the tub a refined, organic aesthetic that complements both contemporary and traditional outdoor spaces.

Inside, the S4N features an ergonomically contoured fiberglass soaking tub designed to comfortably accommodate up to six people. Its smooth, non-porous surface is easy to clean and maintain, providing a practical interior that complements the natural wood exterior.

Off-Grid Wood-Fired Hot Tub Heating

The S4N is designed for homeowners who want the authentic experience of a wood-burning hot tub without an electrical connection. Its integrated high-efficiency wood stove uses the energy generated by fire to heat the water naturally, eliminating the need for conventional hot tub wiring.

At the center of the heating system is an advanced corrugated stove with a secondary chamber that transfers additional heat from the smoke. This design can reduce wood consumption by up to 50% compared with other wood-fired hot tubs, helping improve heating efficiency while reducing the amount of firewood required.

The stove's water circulation system draws cooler water through a lower channel and returns heated water through an upper channel, helping distribute warmth throughout the tub for a more consistent soaking temperature.

Efficient Heating for Your Outdoor Wellness Routine

The S4N is engineered to make wood-fired soaking more convenient by reducing heating time compared with traditional wood-burning hot tubs.

Its efficient heating system can bring approximately 304 gallons of water from 40°F (5°C) to 95°F (35°C) in approximately 1.5 to 2 hours, depending on weather, water temperature, and operating conditions.

The air space between the fiberglass liner and Thermo-Spruce exterior is also heated during operation, helping improve heat transfer and contribute to the system's overall efficiency.

Spacious Six-Person Outdoor Soaking

With seating capacity for up to six people, the Model S4N provides ample room for shared relaxation while retaining the intimate atmosphere of a private outdoor retreat.

The tub arrives fully assembled, helping streamline installation and making it easier to incorporate into an existing backyard, patio, pool area, or outdoor wellness environment.

For a complete Nordic-inspired experience, pair the S4N with an outdoor sauna to create a dedicated hot-and-cold wellness circuit at home.

A Refined Approach to Outdoor Wellness

The SaunaLife Model S4N combines Nordic-inspired design, Thermo-Spruce construction, six-person capacity, efficient wood-fired heating, and electricity-free operation in a beautifully crafted outdoor soaking tub.

Enjoy quiet evenings under the stars, gather with family and friends, or create a dedicated space for relaxation and outdoor wellness. With its natural materials and traditional wood-fired heating, the S4N brings a timeless Scandinavian bathing experience to the modern backyard.
