The SaunaLife Model S4N Wood Burning Hot Tub brings SaunaLife's patented efficiency to a compact 6-person format in a warm Natural Thermo-Spruce finish. No electricity, no plumber, no contractor — just a garden hose, a wood fire, and under 2 hours to 95°F. The S4N's dual-chamber stove draws cooler water from the bottom, heats it, and redistributes through the top — equalizing temperature without pumps or sensors.

At 304 gallons in a 71" interior diameter, it comfortably seats 6 and fits patios where the S6 would feel oversized. A thoughtfully sized backyard luxury.
