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.

What You May Need for Setup
| Item | Why It Matters |
|---|---|
| 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. |
