At BW Sauna Co., every design decision is rooted in durability, performance, and long-term value. That’s why we frame all of our mobile saunas with steel instead of aluminum, and why the base of our stationary saunas is also built from steel.
Strength You Can Rely On
Steel is significantly stronger than aluminum. For mobile saunas that travel thousands of miles, encounter bumps, curves, and temperature shifts, strength matters. A steel frame ensures the structure stays square and solid, resisting warping, twisting, or stress fractures over time. It is built to hold up through seasons of use on the road and still feel like new.
Weight That Works With Us
While aluminum is lighter, that weight savings often comes at the cost of structural integrity. For us, the slightly heavier weight of steel translates to better towing stability and lower risk of flexing or damage in transport. Our trailers are designed to handle the weight efficiently without compromising the sauna experience.
Corrosion Resistance Where It Matters
All steel used in BW sauna frames is treated and coated to prevent rust and ensure longevity, especially critical in humid environments like saunas. Properly prepared steel actually outperforms raw aluminum in resisting corrosion over time when exposed to the moisture and heat of regular sauna use.
Consistency Across Stationary Builds
Even in our stationary models, the base, the point of contact between the sauna and the ground, must resist movement, moisture, and long-term wear. Steel provides a dependable, immovable foundation that holds up under weight, humidity, and shifting temperatures.
Made for Harsh Environments
Our clients use saunas in backyards, lake properties, mountain retreats, and off-grid locations. Steel allows us to build structures that can endure diverse climates and real-life use, not just showroom conditions.
Framing – It is the fitting together of pieces to give a structure support and shape. Headers are built over windows and doors to support the roof load.
Insulation – This is the insulation of the unit. It’s a standard fiberglass insulating material and works to trap air and slow the transfer of heat.
Breathable Membrane – This is a breathable, water-resistant membrane made to resist moisture and release water vapor and works as an air barrier to the structure.
Maintenance Free Siding – This is the outer layer of the structure. It’s a fully waterproof, maintenance free siding option, and is available in many different colors/styles.
Sheathing – 7/16″ OSB sheathing applied over the framing, which holds everything together and prevents the building from ever swaying or bending. It’s used as a nailing base for your siding materials as well.
Foil Vapor Barrier – This is applied over the framing in the hot room areas. It serves as a vapor barrier to the exterior, while also reflecting the heat back inside the room.
Furring Strips – These are used to separate the wood paneling from the exterior wall, to give an air gap for the space to breathe. It helps to dry the wood and is crucial for reflecting the heat back into the room.
Wall Paneling – Commonly used as cedar T&G, but many different forms of paneling can be used. This is the outer layer of the interior and is a wood that can soak up steam and deal with heat absorption without any type of long-term damage. It is also highly resistant to fungus, rot, and decay.
We’ve sourced some of the best wood on the market to offer a wide variety of food finish options. Below are some of the most popular wood finishes our clients have used.
We will work with you to understand and advise the right heat source based on your lifestyle, sauna size, and features.
