SaunaLife S6 7-Person Wood-Burning Hot Tub

The SaunaLife Soak-Series Model S6 delivers exceptional craftsmanship, performance, and comfort in a beautifully designed wood-burning hot tub built for serious relaxation. Inspired by Nordic traditions and engineered for modern outdoor living, it transforms any backyard into a private retreat.

Select between natural Spruce (Model S6N) or black painted Spruce (Model S6B) finishes to best suit your design style. The 1.65” thermally enhanced Spruce surround delivers exceptional durability and long-lasting performance.

The Model S6 arrives fully assembled and is easy to set up, so you can spend less time preparing and more time enjoying. Its ergonomically contoured fiberglass tub comfortably fits up to 7 people, making it ideal for social gatherings or quiet evenings under the stars. The smooth interior surface cleans easily, while the exterior is wrapped in thermally modified spruce for enhanced durability, weather resistance, and natural beauty.

Designed and crafted in Northern Europe, this super-efficient hot tub heats in up to 1/3 the time of traditional wood-fired models—without requiring any electrical connection. At the heart of the Model S6 is an ingenious self-cleaning corrugated stove with a secondary combustion chamber that captures heat from smoke, reducing wood consumption by up to 50% compared to other hot tubs.

Brilliantly engineered airflow between the fiberglass lining and wood exterior super-heats the surrounding space to accelerate water heating. The stove also draws cooler water through a lower channel and redistributes it through an upper channel, ensuring faster, more even heat distribution throughout the tub for a consistently comfortable soak.

The powerful wood stove heats 436 gallons of water from 40°F (5°C) to 95°F (35°C) in just 1.5 to 2 hours—among the fastest heat-up times available for a wood-burning hot tub.
