Heritage Design & Modern Innovation
Traditional Design, Modern Innovation
The tradition of Sauna stretches back thousands of years and spans cultures across the world, bringing people together in restorative warmth. InFinlandthe sauna is a central part of daily life; it is a place for physical cleansing, mental renewal, healing, and a place to connect with community.
At Redwood Outdoors we hold on to this heritage, making our saunas out of natural lumber, the way Finnish sauna builders have doneformanyyears. Ushering them into modern dayindoor spaceswith innovative designs and contemporary materials to make the sauna lifestyle more attainable and a part of your everyday wellness routine.
Designed in Partnership with a Finnish Sauna Expert
Our sauna designs were developed in collaboration with Dr. Lassi A. Liikkanen, a Finnish sauna designer, author, and founder ofSaunologia- a leading sauna design consulting firm based in Helsinki, Finland. He iswidelyrecognized as a leading expert in Finnish sauna design and technologyWithhis guidance, we continue to refine our designs, maximizecomfortand streamlineperformance while staying true to traditional Finnish sauna design principles.
About Our Heat-Treated Lumber
Made of Hemlock
Hemlockisan exceptional material forbuildingsaunas;highlyregarded for beingstrong, durable,andmoisture resistant. In hot environments,hemlockremainscooler to the touchandretainsheatmore effectively than cedar.Allthehemlockused inour saunasis sourced from responsibly managed forests in Canadathatadhere tostrict environmental andsocial standards.
Heat-Treated forExceptionalDurability
Our hemlock undergoes a specializedthermal modification processto increasedurability.Thisthree-phase processbegins withkiln-dryingthe wood, followed byheating it to temperatures above 400°F(204°C),finished byslowlycoolingthrough acontrolledsteamingprocess.This procedure changes thewoodon a cellular level,compressingitsinternal channels to create a denser structure.The result isa stronger material that isbetter protectedagainstdamage fromenvironmental factorssuch asweather and insects. The natural moisture resistance of hemlockisalso enhanced,minimizingswelling and warping over time.
Heat-treatedhemlocklasts longer with minimal maintenance needs,soyoucanenjoyyoursauna for many years to come.
All Natural, Built to Last
Our thermal modification processrelies solely on heat and water—no chemicals involved.Thistechnique increases the lifespan of your wood naturally, without the use ofanyadditives.
Minimal Maintenance
Exterior Sauna Maintenance
Heat-treated hemlock is highly durable; no stain or sealer is required to maintain your sauna’s structural integrity. Left untreated, the wood will naturally weather to a rustic grey over time due to sun exposure, without losing its strength.
A water-based stain can be used to maintain or change your sauna’s exterior color. Note: stains should never be used inside the sauna.
Interior Sauna Maintenance
Our heat-treated hemlock is built to withstand the hot and humid sauna environment; no sealers are required on the interior walls. In high-traffic areas such as benches and floors, applying a protective treatment is recommended to guard against dirt, sweat, and body oils.
Recommended interior treatment options include:
Sauna grade paraffin oil – only a light coating on the benches and floor is needed, preserving the deep natural color of the wood. We recommend sauna safe Harvia Paraffin Oil.Note: only use sauna-grade paraffin oil.
Supi Sauna Wax – a nontoxic treatment safe for walls, floor, ceiling and benches; Supi Sauna Wax is available in three different finishes: clear, black, and white.
Sauna Heater Maintenance
Sauna heaters require little maintenance. Simply cleaning the heater and taking care of the rocks will keep your heater running in peak condition for years to come.
To maintain your heater, follow these easy steps:
Periodically wipe the exterior of the heater with a soft cloth and use a mild cleanser to remove any water spots if needed—we recommend Harvias Heater Cleanser.
Every 6 months, restack and inspect your heater stones. As you pull out the stones, look for cracks, chips and excessive wear. Remove and replace any damaged stones.
Rinse the stones with warm water, lightly scrubbing any that might have slight calcium build up, letting them air dry before restacking in the heater.
After 1 to 2 years, replace your heater stones. For heaters that use split-face stones, upgraded options are available, like vulcanite stones for better steam or the longer-lasting elite pro stones.

Before starting your sauna build, carefully read through your assembly manual and gather all necessary supplies.
Recommended Tools
Sauna assembly requires common household tools, including:
Power drill with T20 ("torx") bit
Rubber mallet
Hammer
Two adjustable wrenches
Measuring tape
Level
Choose the Right Location
Select a stable, level location with sufficient clearance for assembly and access.

Check Local Building Requirements
Depending on your location, a building permit or HOA approval may be required.
Always check local regulations before starting installation.
Hire an Electrician
A trusted licensed electrician must be hired to install your sauna heater.

A solid, level base is essential for the longevity and performance of your sauna.
Recommended foundation types include:
Level concrete
New vinyl or laminate surface

The foundation must support the full weight of the sauna and all occupants.
It will be wet inside your sauna, so be sure you’re building on a surface that is not easily damaged by water.
Installation on a carpeted surface is not recommended.

Before assembling:
Read through the entire assembly manual and watch the assembly video
Verify all pieces in the sauna kit using the parts list included in the manual
