At BW, we work to handcraft lifetime quality custom mobile and home saunas to become a cornerstone of homes, lives and culture by elevating the quality, accessibility, and longevity.

Why BW Sauna Co?

Why Choose BW Sauna Co?

In a world where everything is bought from large corporations manufacturing parts with the cheapest labor, we wanted to go in another direction.

We as custom outdoor sauna builders have the privilege to work with some of the best craftsmen in Minnesota. Fellow Americans pushing to keep our economy strong. Those that work with their hands to make a living, making a difference, in small ways and big. The saunas we build are a lasting testament to these people.

Your Home Sauna Should Tell a Story

Story Driven Design

Take yourself to the coldest day on the winter North Shore. The blackness of the night while you look out into the -30-degree air. The waves, never-ending voice, were always heard but not seen—the howling of the winds caught in the jagged shore. Stepping into the dim lit warmth, the fire dancing off the window's reflection.

A Sauna on the cliff's edge of Lake Superior transports you to another world. A humbling peace in the shadow of a giant.

Mobile Saunas for Your Next Adventure

For thousands of years, saunas were confined to where they were built. Now, in the heart of Minnesota, mobile saunas offer the ability to get your sweat on wherever the road carries you, from a cliff edge to the shores of the great Lake Superior. Our wood-fire saunas are ideal for anything from post-exercise recovery to vacation destinations to extreme cold plunges. The possibilities are truly endless.

Handcrafted Quality On The Go

Handcrafted BW mobile saunas offer a real treat for anyone who loves to sauna. It takes everything to a whole new level when you’re able to bring your custom sauna experience to your favorite locations anytime of the day. 

We chose steel because it represents the reliability and go-anywhere character of BW Sauna. The last thing you should be thinking about when you enter our saunas is if you damaged the sauna on the road there.

“If your truck can go there, your sauna should too!”

We are about craftsmanship and sourcing quality materials, period: no fluff, no nonsense, just the best possible mobile saunas for sale at a fair price.

Saunas are easy to build to just look good, but water, heat, and steam have a way of separating looks from quality. Some saunas use wood jointing that separates and warps over time. With BW, we bring reinforced jointing and thick wood paneling to ensure your sauna not only feels solid but will keep feeling that way well into its years of use.

-30 degrees out? Some saunas skip out on insulating the floors or not giving proper heat-reflecting coverage in the name of price and weight. When heat is the primary purpose of your sauna, heat should be the top priority. We insulate every last inch to ensure your sauna heats up hotter, faster, and in the coldest conditions.

Mobile Sauna Vs. Home Sauna?

Questions We Get Asked Often

What is a mobile sauna and is it really as good as the sauna in my home?

Mobile saunas are fairly new. They have started to gain popularity in the United States with many trailer sauna delivery options. Mobile saunas can be every bit the heat quality of a home sauna.

how long will a mobile sauna last?

Mobile saunas have a wide range of craftsmanship and structural quality. Some factors such as having a steel frame, proper heat shielding and siding make all the difference. Our saunas are designed to last decades if taken care of properly.

Can I build my own mobile sauna?

If you're passionate about building mobile saunas, that makes the both of us. Yes, it is possible to build your own sauna. It does take good planning and patience to truly get the results you envision. Unlike backyard saunas, mobile saunas will require an understanding in metal works for the trailer frame.

Is a custom mobile sauna worth it?

Mobile saunas offer unparalleled ability to get a full relaxation anywhere you wish to go. By the cabin fire or on the ski trip in the rocky mountains. That's what makes mobile so amazing! The biggest benefit of a home sauna is the added value to your property.

What are my heating options?

We find mobile saunas to work best with authentic wood-fired stoves. However, there are gas options, and even electric options if sufficient battery and solar capacity.

How long does it take to build a mobile sauna or home Sauna?

From start to finish we estimate 8 weeks for custom saunas. You can see our shop inventory if we have a sauna prebuilt and ready to order today.

Client Testimonials

The quality of the craftsmanship is 10/10. My clients have been loving the look of the unit and of course the good heat.

They also will stand behind their product and service anything that may go wrong. They've driven down from Duluth multiple times to fix electrical issues or install a new solar panel.

We ended up partnering with BW because they are the best combination of quality and design and value that I've found. Their saunas are beautiful, built to last a lifetime, and reasonably priced.

I've worked with Jayson (the owner) on about a half dozen builds now, he has always been extremely responsive, professional as well as fair and reasonable. I could not recommend BW more strongly. You simply will not find a better value for custom sauna and mobile sauna builds.
