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.

Traditional Scandinavian Design

The Scandinavian mini-cube sauna has a classic beauty in its elegant simplicity. Our cube saunas are constructed with durable bead and cove lumber that fit together forming a strong exterior. This bead and cove system allows the lumber staves to expand and contract naturally, and to form a tight seal. Not only are our cube saunas lovely to look at, their design is incredibly energy efficient and helps to distribute the heat evenly throughout the interior.

Harvia Sauna Heater, Made In Finland

Harvia is the world’s leading sauna heater manufacturer and Harvia heaters are considered the industry gold-standard. Harvia is 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.

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 level, Phillips screwdriver, 7/16″ and 9/16″ open end wrenches, 9/16″ deep socket wrench, vise grips, and a 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!

You'll be so happy you did!! We are. :)

  • HARVIA KIP ELECTRIC HEATER

    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

    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.

  • HUUM DROP ELECTRIC HEATER

    HUUM DROP ELECTRIC HEATER

    The HUUM DROP is an award-winning sauna heater. Made in Estonia, this eye-catching heater is quickly emerging as a stand-out in modern sauna design. Its shape is inspired by the purest element in nature – a water drop. Its round design softens and livens up the interior of a classic sauna, giving it a touch of elegance.

    But DROP isn’t only about the looks. This compact wall-mounted heater can fit up to 120 lbs of sauna rocks. This guarantees both hot temperatures and long-lasting steam. The HUUM is fast to heat up and can reach temperatures of ~195F. The HUUM creates more steam than the KIP heater, but less than the Cilindro heater. It's somewhere in the middle in terms of its “löyly” potential.

    Every HUUM DROP heater comes delivered with HUUM sauna stones and a HUUM UKU Wi-Fi controller. This makes it a must-have heater for customers who like a modern look, combined with modern functionality.

  • Harvia Spirit Heater

    HARVIA SPIRIT HEATER

    The Harvia Spirit sauna heater has an eye-catching and modern design that combines beauty and performance in one package. The soothing curved design of the Harvia Spirit electric heater gives a natural and serene look, which will help put your mind at ease. The Harvia Spirit holds 130 lbs of gorgeous rounded sauna stones that evoke calmness. This generous amount of stones allows bathers to create incredible steam (löyly) in the room. The heater is equipped with a remote WiFi control, which makes usage easy. The Harvia Spirit is truly the spirit of your sauna!

    Harvia is the world's leading sauna heater manufacturer, and Harvia heaters are considered the industry's 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 you and your family can trust. All our Harvia sauna heaters are ETL-certified and are manufactured in Finland.
