Barrel Sauna Model Quadro 300 cm
Our exclusive Quadro barrel sauna series offers a lot of space and headroom for sauna bathing due to its square design, but retains the look and characteristics of a sauna barrel thanks to its rounded edges. For the sauna heater, you can choose between a wood-fired or electric heater. The sauna barrel comes standard with an all-glass door, which can optionally be exchanged for a wooden door with a glass cut-out (at no extra charge). The optional window and panoramic glass options allow you to enjoy the view of nature during your sauna session.

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

How is a barrel sauna delivered?
You have the choice to order our barrel saunas as a self-assembly kit or already pre-assembled from the factory.
Both variants are delivered with a 40t truck with a mounted forklift. Unloading takes place on site at 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.
