Have questions about our barrel saunas? Call us now on 1800 567 8036.
Every Redwood Outdoors barrel sauna kit comes complete with a Harvia electric heater, wooden 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.
Note that some of the photos used are of an 8-person (8ft) unit. The unit for sale here is a 6-person (6ft). It comes with two cradles and two steel bands.
Traditional Scaninavian 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 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.
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!

Absolutely IncredibleMar 24th 2023
I purchased the 6-person barrel sauna and it is absolutely incredible. The materials are top of the line and came with detailed instructions for installation. Their customer support team was able to assist with questions I have about the Harvia unit. If you are looking for an outdoor sauna there is no better company than Redwood Outdoors!!!
Highly Recommend!Feb 28th 2023
Purchased the 6 person barrel sauna. Redwood helped coordinate the delivery because we wanted the Sauna delivery delayed due to a back yard landscaping project. Sauna took 4 hours to complete. While it can hold 6 people you'll be touching unless your skinny. Six 190lb dudes are going to be a cozy fit, but 4 people fit comfortably. 6 months in and so far so good. I use it daily after an icebath. Highly recommend!
Dream Come TrueFeb 15th 2023
It has been a long time dream of mine to have a sauna of my own, and the folks at Redwood Outdoors could not have made the process easier. The sauna was easy to build even for novice builders, and it came out even better than I expected. We decided to go with the Thermowood Barrel Sauna with the wooden stove, and I feel like I am back in Finland. Since we are located in the greater Seattle area, we were able to take a look at it before purchase, too, which helped us choose the model. Wrapping it up, the sauna is great quality and easy to put together, and the team at Redwood Outdoors was fantastic - if you are on the hunt for a sauna, I would recommend them!
Protect your sauna from the elements and keep it looking its best for longer by protecting the wood with a shingled roof. We recommend adding these asphalt shingles to keep water off the sauna and increase the wood’s longevity. The shingles are black in color.

HARVIA KIP ELECTRIC HEATER
The KIP family of electric sauna heaters are traditional Finnish wall-mounted heaters. They heat up fast and reach high temperatures of ~190F within one hour. This design holds up to 40 lbs of rocks, on which you can douse water to create soothing steam. The KIP creates a relatively dry heat and you should expect ~15-25% relative humidity in the sauna. The KIP comes in an attractive stainless steel exterior case that easily mounts on your sauna wall.
Harvia is the world’s leading sauna heater manufacturer and Harvia heaters are considered the industry gold standard. Harvia was established in Finland in 1950 and has built an international reputation for exceptional quality. With a Harvia heater, you know you are getting a reliable product that you and your family can trust. All our Harvia sauna heaters are ETL certified and are manufactured in Finland.
HARVIA CILINDRO ELECTRIC HEATER
The Finnish word “löyly” is the name for the hot steam that rises from your sauna rocks after water has been carefully poured on top of them. The steam turns your sauna into a hot and humid paradise, capable of relaxing even the tensest muscles or stressed minds.
The Cilindro specializes in creating a lot of steam. This is because the heater holds 160 lbs of rocks! All these rocks create a more even heat distribution and an incredible löyly that would make any Finn proud.
The Cilindro has a slightly longer heat-up time than the KIP, due to the number of rocks and is designed to run at a lower absolute temperature. The temperature you should expect from this heater is ~165F, which is the perfect temperature for a steamy sauna (>30% relative humidity) to prevent scalding. Due to the higher humidity in the room, the perceived temperature in the sauna will feel comparable to a drier sauna running at a higher absolute temperature.
HARVIA M3 WOOD STOVE
Classic wood-burning saunas are very special. The crackling fire, warm steam from the rocks, and the ritual of tending the fire all combine to create a timeless and unforgettable experience. The Harvia M3 is a compact wood-burning stove that is perfect for our saunas. The M3 is made by Harvia, the most trusted brand in the sauna industry. Built-in Finland, it is designed to meet rigorous European quality standards.
Harvia does not include a chimney kit with the stove. Redwood Outdoors offers a chimney kit to pair with the M3 stove (details below). Installation of the chimney requires cutting a circular hole in the roof staves. This could be performed by a carpenter or a more experienced DIY customer. The Redwood Outdoors chimney kit is sold separately. If you prefer, you can source the chimney and stove accessories yourself. If you are sourcing yourself, you will need 6’ of 6" diameter double-wall stove pipe, interior protective flashing, a chimney collar, and an external rain flange.
Also, note that the M3 wood stove is larger than the electric heaters and reduces the seating capacity of the sauna.
WOOD STOVE CHIMNEY KIT
If you're going to be using your sauna with a wood stove, this chimney kit will give you everything you need to get going. It includes a chimney, chimney cap, and floor/wall heat guards. Designed to fit the Hariva M3 Wood Stove and all Redwood Outdoors barrel saunas.
