Thermowood 6 Person Barrel Sauna

SKU: BS-1820S Categories: , ,

Are 6 person barrel saunas any good?

An outdoor barrel sauna is hugely efficient

Thanks to the efficient use of air space, there is less energy used to heat the room. Plus, the thick red cedar staves are excellent insulators, allowing the sauna’s exterior to remain cool to the touch, even at the top of the sauna.


The Scandinavian barrel sauna has a classic beauty in its elegant simplicity. Our barrel saunas are constructed with tongue and groove lumber staves that are held tightly together by stainless steel bands and fasteners. This interlocking system allows the lumber staves to expand and contract naturally, and to form a tight seal. The sauna unit sits on support cradles (included) that keep the sauna’s underside above the ground. Not only are our Scandinavian barrel sauna lovely to look at, their design is incredibly energy efficient and helps to distribute the heat evenly throughout the interior.

Thermal-wood Construction 

Thermowood is created by heat treating Scandinavian softwood to temperatures ranging from 180 – 230° in special chamber kilns for up to 96 hours. Steam is used as a protective gas and helps to prevent the wood from splitting and becoming damaged during treatment.

Thermowood’s Characteristics & Qualities

This process causes chemical and structural changes to occur within the timber, which therefore alters some of its characteristics and qualities. Some of the characteristics and qualities that make Thermowood such a popular specie includes:

Dimensionally Stable – The intensive heat the wood is exposed to during its production dries out deep into the core, causing all moisture and resin to be removed from the timber. Thermowood therefore doesn’t react to changes in humidity as drastically as untreated wood (the risk of swelling, cracking and shrinkage is decreased), allowing it to retain its shape far better. The wood also doesn’t secrete sap or resin even in high temperatures.

Environemntally Friendly – The softwood used to produce Thermowood originates from well-managed, PEFC-certified forests, and as no chemicals or foreign substances are involved during its production, Thermowood is an environmentally friendly material produced by using only natural methods.

Resistance to Rot and Fungi – Due to the heating process breaking down hemicellulose, the wood doesn’t contain the appropriate nutrients to allow rot and fungi to grow and develop.

Increased Longevity – When wood is treated with heat, its average life span is prolonged meaning your sauna will last a lifetime!

Improved Insulation – Wood that has been heat treated is much more porous than untreated wood, vastly improving its insulating properties.


Our sauna kit includes a back rest so you can get comfortable. Sit on wooden benches and enjoy the company of friends and loved ones in a sauna room filled with soft lighting and enjoy the aromatic scents of the thermowood. Our saunas give bathers a truly authentic and relaxing Scandinavian sauna experience. A towel hook (included) is a great place to keep towels for drying off and cooling down between rounds. 


Putting together the our sauna kits is easy! All our saunas are designed with the DIY customer in mind. All the pieces are pre-cut and grooved, so no sawing or cutting is required.
