SaunaLife S4 Hot Tub

No, the SaunaLife S4 is entirely off-grid. It relies exclusively on the stainless steel wood-burning heater, meaning you don't need to worry about wiring, pumps, or electrical outlets.

Under normal conditions, the wood-burning heater can bring the 304 gallons of water to a comfortable temperature in under two hours. The dual-compartment heater design is engineered specifically for rapid heat transfer.

Thermo-Spruce is heat-treated to remove moisture and resin, making it significantly more resistant to rot, decay, and warping than standard cedar. This process extends the lifespan of the exterior cabinet, ensuring it holds up better against the elements over time.

Not at all. The unit arrives fully assembled, so you simply need a level, stable surface to place it on. Because it requires no plumbing or electrical hookups, you can begin filling and heating the tub almost immediately upon delivery.

The S4 is designed to comfortably accommodate up to six bathers. With a 71-inch interior diameter, there is ample space for a group to sit without feeling cramped.

Yes, the dark grey fiberglass shell is non-porous and smooth, which makes it much easier to wipe down and sanitize than wood-lined tubs. It also provides a more ergonomic, contoured seating experience.
