Documentation & Resources

The model-specific assembly and operation manual ships in the box with every Wellis sauna. For warranty terms and the Wellis product warranty document, see the Warranty tab.

Why Choose a Wellis Sauna

Wellis is one of Europe's largest spa manufacturers — over 200,000 units shipped to 50+ countries since 2003. Every sauna ships factory-sealed from Hungary, with the same engineering pedigree as Wellis hot tubs.

Canadian hemlock pine interior

The classic premium sauna wood — low knot density, tight grain, low heat conductivity. Comfortable on bare skin even at temperature, and visibly higher quality than the Nordic spruce found in entry-level saunas.

EU manufacturing & spare parts

Built in Hungary. Spare parts move within the European distribution network — no transatlantic shipping waits for replacement heaters, glass, or controls. Backed by the Wellis manufacturer warranty.

Free delivery to DE & AT
