Product Description
Introducing the RAVN L: Spacious Scandinavian Design with a Modern Silhouette
Experience elevated outdoor relaxation with the RAVN L. Designed with the same modern, box-style Scandinavian architecture as the RAVN series, the RAVN L offers increased interior space while maintaining a clean, contemporary footprint. Comfortably accommodating 4-6 bathers, it is ideal for those seeking a more spacious sauna experience without overwhelming their outdoor space.
Premium Construction & Materials
The RAVN L is crafted for long-term outdoor performance and visual refinement.
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.

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.
- Robust Wall Construction: Built with 42 mm (1.65") thick solid wood walls to ensure excellent heat retention and structural durability.
- Durable Roofing: Finished with PVC/EPDM roofing for dependable weather protection. Roofing is offered as an add-on, or customers may apply their own custom waterproofing solution.

- Lower Bench: Secondary bench and step system allows easy access and temperature variation.
- Tempered Glass Front: Large glass front and tempered glass door (192 cm × 69 cm / 75.6" × 27.2") enhance natural light while maintaining thermal efficiency.
