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. In Finland the 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 done for centuries. Ushering them into the modern day with 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 of Saunologia - a leading sauna design consulting firm based in Helsinki, Finland. He is widely recognized as a leading expert in Finnish sauna design and technology. With his guidance, we continue to refine our designs, maximize comfort and streamline performance while staying true to traditional Finnish sauna design principles.
About Our Heat-Treated Lumber
Made of Hemlock
Hemlock is an exceptional material for building saunas; highly regarded for being strong, durable, and moisture resistant. In hot environments, hemlock remains cooler to the touch and retains heat more effectively than cedar. All the hemlock used in our saunas is sourced from responsibly managed forests in Canada that adhere to strict environmental and social standards.
Heat-Treated for Exceptional Durability
Our hemlock undergoes a specialized thermal modification process to increase durability. This three-phase process begins with kiln-drying the wood, followed by heating it to temperatures above 400°F (204°C), finished by slowly cooling through a controlled steaming process. This procedure changes the wood on a cellular level, compressing its internal channels to create a denser structure. The result is a stronger material that is better protected against damage from environmental factors such as weather and insects. The natural moisture resistance of hemlock is also enhanced, minimizing swelling and warping over time.
Heat-treated hemlock lasts longer with minimal maintenance needs, so you can enjoy your sauna for many years to come.
All Natural, Built to Last
Our thermal modification process relies solely on heat and water—no chemicals involved. This technique increases the lifespan of your wood naturally, without the use of any additives.
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 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:
Delivery: What to Expect
Redwood Outdoors saunas and cold plunge tubs are shipped using freight delivery to ensure safe, secure transport from our warehouse to your home. Below is everything you need to know about shipping and what to expect on your delivery day.
How Redwood Outdoors Products are Shipped
Our saunas and cold plunge tubs are shipped in durable wooden crates designed to protect the product during transit.
We partner with multiple trusted freight carriers to ensure your order arrives safely and efficiently at your curbside.
If you’ve ordered multiple large products—such as a sauna and a cold plunge—they may arrive in separate shipments.
Freight Delivery
Our shipments are delivered by a large freight truck, typically equipped with a liftgate. This allows the carrier to lower the crate to ground level upon arrival.
Delivery Day
Your shipment is on the way, here's how to prepare.
Once your order arrives at the carrier’s local depot, they will contact you to schedule a delivery appointment.
All freight shipments are curbside delivery, meaning the crate is placed at the end of your driveway or nearest accessible location.

Review Instructions and Gather Supplies
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:
Choose the Right Location
Select a stable, level location with sufficient clearance for assembly and access. Be sure the area allows for proper drainage and is within reach of your electrical connection. Thoughtful site selection helps ensure safe operation and long term durability.
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. Sauna heaters do not plug into standard outlets and must be hardwired to your electrical panel.
Build a Solid Foundation
A solid, level base is essential for the longevity and performance of your sauna.
Recommended foundation types include:
The foundation must support the full weight of the sauna and all occupants.
