This Extra-Wide Thermowood Barrel Sauna is a Redwood Outdoors exclusive design, you can't get a sauna this beautiful anywhere else! We've increased the diameter of this barrel sauna to 7 feet, so the interior feels spacious and there is tons of head room! The perfect choice for anyone worried about fitting into our standard barrel saunas. 

Every Redwood Outdoors barrel sauna kit comes complete with a Harvia electric heater, a heater guard, water bucket & ladle, sauna rocks, and interior seating benches. Our saunas heat up to 195 F in under an hour, and can be enjoyed either wet or dry, catering to a true Scandinavian sauna experience.

Cycle Between High And Low Temperature Without Leaving Your Sauna With Two-Level Seating

In Finland, the rule for a truly deep sauna bath is that your feet should be above the heater. We've designed this sauna so you can do just that. Sit on the top bench and get your whole body into the hottest part of the sauna to take your sweat to the next level! Once you're ready for a break, move the lower benches to cool down. Cycle between the top and bottom bench to natually adjust your temperature without having to adjust your heater, making for an epic sauna session. 

Traditional Scandinavian Design

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.

Thermowood 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.

Learn more about thermowood in our FAQ section!

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.

The Relaxation Comes Naturally

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. 

Manual Control or Wi-Fi Control Heater Options

Our manual control heaters have two dials: a temperature dial and a timer. The timer can be set for up to an 8-hour delay, meaning you set your heater to come on while you are out and your sauna will be ready when you get home.

Our digital Wi-Fi heaters can be controlled via the digital wall pad mounted nearby your sauna, or from any smartphone or tablet. The big convenience of the Wi-Fi control is the remote start capability which allows you to pre-heat your sauna from anywhere—whether at the office or on the slopes. With few taps on your phone, your sauna will be ready when you get home. Wi-Fi heaters can also be pre-set to come on at a specific time of day, such as early in the morning. 

Unfortunately, you cannot upgrade a manual control heater to a digital Wi-Fi system in the future. While the manual and digital heaters look very similar, they are in fact totally different heaters. This means you must select the control system you are going with at the outset.

Easy Self Assembly

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. 

Anyone with novice woodworking skills could build one in approximately 4 hours. All the assembler will need is a spirit level, a Phillips head screwdriver drill, an adjustable wrench, a hammer, and a rubber mallet.

Shipping Across The USA

We ship our saunas to everywhere in the United States to sauna enthusiasts who enjoy the wellness benefits of heat and steam!

    We purchased the Extra-Wide Thermowood 6 person barrel sauna in December. Their staff was very helpful and addressed all of our questions and concerns promptly. The assembly instructions were easy to follow and my wife and I had no problem putting it together. The quality is excellent and everything was there. We optioned it with the larger heater. It is working perfectly and we use it nightly. We did look at local sauna dealers and found the pricing to be double what we paid for this sauna. Excellent value and we would recommend their products to our friends and family.

    I ordered a Redwood Outdoors barrel sauna during early Covid lockdown in 2020. It was a stressful time and I needed to find some relief. It arrived quickly, and was easy to assemble by myself. I only needed my neighbors help to install the very last stave on the top. Since then, my wife and I have enjoyed the sauna immensely. It provides relief from a very stressful world, and the health benefits are clear. I'm loosing weight, breathing better, and my sleep pattern has improved. I'd highly recommend getting a sauna from Redwood. The quality of the wood and manufacturing is top notch. My only regret is not ordering the hot tub as well!
