Barrel Sauna Model Quadro 400 cm 2-Room
Our exclusive Quadro barrel sauna series offers plenty of space and head height for sauna bathing due to its square design, while maintaining the appearance and characteristics of a sauna barrel with its rounded edges. For the sauna heater, you can choose between a wood-fired or electric heater. The sauna barrel comes standard with a full glass door, which can optionally be exchanged (at no extra charge) for a wooden door with a glass cutout. The optionally available window and panoramic glass options allow you to enjoy the view of nature while having a sauna.

Properties and production of thermo-wood :
During the thermo-wood treatment, the wood is heated to temperatures between 180 and 230° Celsius, excluding oxygen. This significantly reduces the wood's ability to absorb water, and wood-destroying fungi and bacteria thus lose their food source. This increases the durability of the wood.
- particularly long durability
- resistant to rot
- reduction of swelling and shrinking behavior
- reduction of splintering and cracking
- the wood remains very dimensionally stable
- improvement of load-bearing capacity
- water absorption is significantly reduced
The thermo-wood treatment gives the wood a uniform brown color, which, like all other woods, grays under UV radiation. We therefore recommend treating the wood with a wood preservative varnish.
Optimal steam distribution in the interior, thanks to the special Cubus design

How is a barrel sauna delivered?
You have the choice of ordering our barrel saunas as a kit for self-assembly or already pre-assembled from the factory.
Both options are delivered by a 40t truck with a forklift. Unloading takes place on site to the curb.
Please note that we cannot transport an already assembled sauna into your garden.
We therefore recommend that you arrange for a crane or wheel loader for further transport into your garden.
