The feel of a full-sized sauna, in a more compact and easy-to-move design. Our 10ft Ontario Mobile is built for flexibility, comfort, and simple setups—whether that’s your backyard, cabin, or favorite outdoor spot.
Comfortable capacity
Compact layout
Hot room focused design
Custom window options
The 6.5 x 10 layout is designed as a dedicated hot room, making the most of a smaller footprint while still delivering strong, even heat. This model is ideal for personal use or smaller groups and is easy to place and tow.
Its compact size makes it a great option for homeowners who want a high-quality sauna without needing a large trailer or extended setup space.
The Ontario Mobile includes a tempered window in the hot room to bring in natural light and help the space feel open. Window size and placement can be customized depending on privacy, views, and how you plan to use the sauna.
All window options are designed for sauna conditions and help reduce fogging and moisture buildup. Dimmable LED lighting under the benches and overhead provides soft, adjustable lighting for any time of day.

Windows designed to eliminate claustrophobia, moisture & fog problems
The interior is finished with cedar tongue-and-groove on the walls and ceiling, paired with solid cedar benches for comfort and durability. These materials are selected to handle heat, moisture, and regular use over time.
On the exterior, the sauna comes standard with low-maintenance metal siding and roofing. A wide range of color options and material upgrades are available to match your style or surroundings.
Even a compact mobile sauna goes through major temperature changes. The Ontario Mobile is fully insulated and built with sauna-specific materials to handle repeated heating and cooling, whether you’re using it year-round or seasonally.
From ventilation to heat shielding, each detail is designed for safe operation, consistent performance, and long-term reliability.

YES! That’s the awesome part. Many other mobile saunas will have inferior insulation, and quality and generally feel like a compromised decision. Our’s simply don’t. They bring 100% the quality sauna experience you’ll find in any luxury getaway spa. Without all the people, scheduling and nonsense.

This sorta depends on a lot of things. What you’re looking to get out of it, age, intensity. However, 10-20min sessions are typical for medium to high heat. And of course some like to keep it a bit lower temp to allow for conversational relaxation. The great part is, you control it all as you like. Just remember to stay properly hydrated.

This is where BW shines. Businesses buy from us due to the low maintenance and ease of use for customers. All benches, can be removed easily, and the floor mat removed to allow for a good clean. We recommend washing down the interior cladding periodically and ventilating to keep everything dry after each use.

Our saunas come recommended with a wood stove for the heat output. We do offer external battery units to be integrated into the lighting systems to ensure you’re always able to turn the lights on when you need.
Mobile saunas usually do not use a lot of electricity with heat source being wood or gas. Most models consume between 500 to 1500 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 as home backyard saunas they take when they go camping, to their cabin, relatives or even just to the fire side lake. When home, they keep it on a backyard slab and use it 2-3 times a week, or some bring it into their regular daily routine. Depends how much Fin you got in you I suppose.

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

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

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.
