We work with quality people, and ensure we use the best material available, built by a team that truly cares.


We always stand behind our product. If you have questions or issue that may arise over the years, we are available to help.  

Why BW Sauna?

In a world where everything is bought from large corporations manufacturing parts with the cheapest labor they can find, we wanted to go in another direction. When we set out to build the best handcrafted custom saunas we could right here in Duluth Minnesota and we knew it had to start with finding the best people behind every bolt, board and weld. 

We have the privilege to work with some of the best craftsman in Minnesota. Fellow Americans that are pushing to keep our economy strong. Those that work with their hands to make a living, making a difference, in small ways and big.

Saunas can be as small as 4×6, or as big as you can imagine. It greatly depends on how many people you will regularly seat. We recommend considering at least 4 person sauna. However, do consider the time it will take to heat, the amount of wood and energy it will take to heat the sauna sufficiently. 

While wood offers a great traditional experience, electric brings new comfort being able to start your sauna from your home, not needing to worry about wood. Electric also may work well in areas that have frequent fire warnings. 

Well, that’s a long question in itself. There are a great amount of resources available. We’d like to be one too! If you are working on a sauna of your own, and have any questions. Feel free to message us and we’d be happy to help.  

Finding a good sauna builder is tough. Search saunas for sale near me and you’ll find dozens of companies all making great saunas. Our Humble advise, is to focus on the people, reputation and passion. Work with someone who cares about sauna as much as you do and you won’t go wrong. 

The quality custom sauna can cost anywhere between 10,000 and as far as 50k + 

Designed for Heat

Created For Longevity

A quality custom sauna brings together 8 layers of material design to keep in heat, weather out, and moisture free to leave after you've finished your session, all while bringing out the natural beauty of unique design.

Our saunas start with a sturdy 2×4 frame, with exterior OSB, Tyvek, with all whether metal siding. On the inside, we use insulation on all walls including the floor if elevated. Followed by interior metal heat shield, cedar or pine spacers to prevent moisture traps, plus the finish cedar

Redefine your Relaxation Space

Handcrafted Quality

When you build a custom sauna with BW, you build something truly special. A center piece of conversation, and sauna can bring people together and become a cornerstone of your relaxation space. When your sauna is  designed especially for you, it means so much more. 

We choose steel because it represents the reliability and go anywhere character of BW Saunas. 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 make 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, with thick wood paneling to ensure your sauna not only feels solid, but will keep feeling that way, well into its years of use.

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

-30 degrees out? Some saunas skip out on insulating the floors or giving proper heat reflecting coverage in the name of price and weight. When heat is the main purpose of your Sauna, heat should be the top priority. Our saunas are made for the cold! We insulate every last inch to ensure your sauna heats up hotter, faster, and in the coldest of conditions.

Mobile Saunas for your next adventure.

For thousands of years, saunas were fixed 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. Our wood fire saunas are ideal for anything from post exercise recovery, to vacation destinations to extreme cold plunge. The possibilities are truly endless.

As the Founder of the 612 Sauna Society and Co-owner of Stokeyard Outfitters, I've worked with a lot of sauna builders over the years. 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.

Jayson and Brandon at BW are seasoned builders that know how to layout beautiful sauna spaces - for me, on a trailer. I most enjoyed how dedicated to the craft of building they are and they patience to guide me through a final build spec.

I had BW Sauna build a custom sauna in our new home and we are absolutely thrilled with how it turned out. The crew was great to work with and very attentive to detail and did a great job on the sauna and changing room. These folks definitely know sauna's and I would highly recommend them if you are wanting a mobile sauna or a custom sauna!!

I bought a mobile unit from BW sauna and have nothing but great things to say about working with Jayson and Brandon.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.Would recommend!
