Built for Off-Grid Soaking and Outdoor Simplicity
The SaunaLife S6B is designed for buyers who want a hot tub experience that feels more natural, more independent, and more connected to the outdoor environment. Instead of relying on electricity, this model uses a 304 stainless steel wood-burning heater to warm the water while the engineered heater channel helps circulate water for more even temperature distribution. The result is a soaking experience centered on simplicity, heat, and atmosphere rather than pumps, jets, and screens.
Wood-Fired Heating Performance
The SaunaLife Model S6B delivers an authentic wood-fired soaking experience that combines traditional craftsmanship with modern engineering. Its 304 stainless steel wood-burning heater, dual heat chambers, and engineered water circulation channel work together to warm the tub efficiently while eliminating the need for electricity, pumps, or electronic controls.

The stainless steel heater and secondary heat chamber are designed to maximize heat transfer while helping circulate warm water naturally.
No electrical hookup is required, making the S6B an excellent choice for cabins, remote properties, and outdoor wellness retreats.

What You May Need for Setup

| Level, load-rated base | Concrete or pavers are common. The surface should support the filled tub, water, and bathers. If installing on a deck, confirm capacity with a qualified professional. |
| Water fill access | A standard garden hose is commonly used for filling. |
| Drain plan | Use the integrated drain tap and plan where discharge water will go on your property. |
| Firewood storage | Seasoned hardwood generally burns hotter and cleaner than wet wood. Keep it dry and covered. |
| Local code check | Solid-fuel appliance rules can vary by municipality or HOA. Confirm clearances and setbacks before installation. |
