A balanced portable sauna for those who want the full experience. Comes with a cool-down changing room and the best in handcrafted. custom-quality.
The nimble and agile Huron is here as the entry-level outdoor mobile sauna. At 10 ft, it will fit nicely in your garage or tucked away in your backyard.
We build out completely custom mobile saunas for businesses use. Easy to maintain, long lasting and big enough to fit large groups.
From the cladding and benches to the shape of the stove, each BW sauna reflects our evolving craftsmanship, standards, and deep commitment to detail. Part of that detail is bringing a selection of some of the best wood products available. Thermory is the exclusive provider of our wood library, offering natural and chemically free finishes in a variety of textures and colors.
We use sauna in different ways. For some, it’s a way to bring heat from home to the cabin. For others, it’s a dependable asset for a sauna business, built to be low-maintenance and easy to service day after day. And for many, it’s the edge that makes winter sports and cold-weather adventures more enjoyable, helping you recover and get back out faster.

Sauna with Purpose.
We believe in leaning into the hard parts of life. The uncomfortable seasons and the moments that reveal who we are. Sauna isn’t just about heat; it’s about discipline, reset, and recovery. It’s about stepping away from screens and noise to rediscover ourselves and establish clarity we can use to built a better tomorrow. Silence has a way of bringing out what actually matters in our lives. From day one, we’ve built saunas that invite you into that moment again and again. Because comfort won’t make you stronger. But heat will.
Confidently American Made
No filters. No performance. Just presence.
BW doesn’t care what you believe, what you look like, or what side you’re on. That all falls away when you enter a sauna. They’ve been a shared experience cultures and eras. Common ground. We could sit in a sauna with a stranger from 2,000 years ago and share the same breath, the same stillness, the same human experience. We believe a sauna is the place where opinions take a backseat and presence takes the lead. It’s not about what you post. It’s about how you feel when you step out.
YES! That’s the awesome part. Many other mobile saunas have inferior insulation and overall quality, and generally feel like a compromised decision. Ours simply don’t. They deliver 100% of the quality sauna experience you’d find at any luxury getaway spa, without all the people, scheduling, and nonsense.

This is where BW shines. Businesses buy from us because of the low maintenance and ease of use for customers. All benches can be removed easily, and the floor mat can be removed to allow for a thorough clean. We recommend washing down the interior cladding periodically and ventilating to keep everything dry after each use.
For more information on this issue, please see “How to take care of your outdoor custom sauna maintenance tips.”
Our saunas are recommended with a wood stove for strong heat output. We also offer external battery units that can be integrated into the lighting system to ensure you can always turn the lights on when you need to.
Mobile saunas usually do not use a lot of electricity, since the heat source is typically wood or gas. Most models consume between 500 and 1,500 watts, similar to many household appliances, and are designed to be energy-efficient.

We don’t know your personal life, but we can say this. A lot of our customers treat their mobile saunas like backyard saunas that they can take camping, to their cabin, to relatives, or even just to a fireside lake spot. When they’re home, they keep it on a backyard slab and use it two to three times a week. Some even build it into a daily routine. It depends how much Finn you’ve got in you, I suppose.

Portable saunas or trailer saunas are as safe as any camper compared to a home. We only ask that you don’t sauna down the freeway.

A mobile sauna is a portable structure that meets the key characteristics and requirements of a traditional stationary sauna, but it does not require significant foundation work for installation.
But what does this actually mean for us? To us, a mobile sauna means no compromise. It isn’t a tent or a compromised trailer shack on wheels. It should deliver every bit of the high-quality, premium feel, with the added ability to take it wherever you go.

When you start exploring what a custom sauna could look like, you might already have that exact idea in mind: that perfect finish with a wide panorama window. Or something more true to its history, humbly nestled in the lakeside corner. Either way, we hope this catalog offers inspiration for your journey
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.
