JONAS Classic Lounge in Shou Sugi Ban with BENAS Hot Tub – near Munich, Germany

A complete wellness terrace with a view of the Alpine foothills.

In the green countryside near Munich, with the Bavarian Alpine foothills on the horizon, this home now has a complete outdoor wellness area. Celsium built and installed a JONAS Classic Lounge sauna under the covered terrace, with a BENAS wood-fired hot tub on the deck right beside it.

Shou Sugi Ban and Thermowood

The exterior combines two of our favourite materials. Black Shou Sugi Ban charred timber gives the sauna a calm, architectural look and protects it against rain, snow and sun. Warm thermowood on the door and frames adds a natural contrast. The large glass front of the lounge opens the sauna to the terrace and the landscape beyond.

Inside: Thermo Aspen and a HUUM Drop Heater

The interior is finished in Thermo Aspen, a heat-treated wood with a warm honey tone that stays pleasant to the touch at sauna temperatures. Heat comes from a HUUM Drop electric heater, with its open basket of stones for soft, even steam. LED lighting under the benches and along the backrest sets a calm evening mood, and a window next to the heater frames the view of the meadows.

A BENAS Hot Tub a Few Steps Away

Next to the sauna stands a black BENAS hot tub, heated by its own wood-fired stove and finished to match the Shou Sugi Ban sauna. Between sauna rounds, the owners can relax in warm water under the open Bavarian sky, in every season.

This project shows what we enjoy most: sauna, hot tub and terrace designed as one wellness space that fits the home and its surroundings.

Crafted in Europe. Built for a Better Life.
