SaunaLife S4N Wood-Fired Hot Tub — Fast-Heating, 6-Person Outdoor Spa

Luxury Wood-Burning Performance

The SaunaLife S4N delivers a premium, electricity-free soak with a highly efficient wood-burning system. Its self-cleaning, corrugated stove features a secondary heat chamber that reclaims exhaust heat to cut wood use and speed warm-up. Super-heated air between the fiberglass liner and Thermo-Spruce surround accelerates heating, while internal flow channels circulate water for an even, comfortable temperature.

Scandinavian Craft, Ready to Enjoy

Handcrafted in Northern Europe, the S4N arrives fully assembled and built to last with a weather-resistant Thermo-Spruce exterior and a thick, contoured fiberglass interior that’s easy to clean. Seat up to six comfortably and enjoy rapid heat-up of roughly 304 gallons from about 40°F to ~95°F in ~1.5–2 hours—perfect for family nights and backyard gatherings.

Natural Finish That Fits Any Setting

The S4N’s natural Thermo-Spruce finish blends beautifully with modern patios, decks, and garden spaces while delivering the durability and thermal performance you need for year-round use.
