In true entrepreneur fashion, Spencer Luedtke โ founder of Luedtke Design & Build โ sat in a friendโs sauna, assessed the structure and thought, โI could build this.โ
With several years of experience in remodeling and new construction already under his belt, adding saunas to his repertoire felt far more exciting than intimidating. Luedtke was already a proud owner of his self-proclaimed โbuilder brain,โ so the new adventure in his business was a welcome challenge.
Over a year later, LDB Sauna is a brand in its own right, as Luedtkeโs three-man team crafts cedar barrel sauna kits out of a charming 3,200-square-foot warehouse, delivering relaxation to the community and beyond.
THE DEAL WITH BARREL
โSauna was just in the air,โ Luedtke reflects on the winter months of 2023. โI was in the middle of another six-to-eightmonth new build, using my friendโs barrel sauna occasionally, and I decided that I could replicate it.
โMy partner was talking about it a lot at the time, too. She had memories of our sauna retreat in California, and talked about bringing that type of experience closer to home. I already had a lot of woodworking equipment, so all it took were a few new specialty pieces to make a prototype.โ
But why the barrel?
More efficient heating, for one, Luedtke says. โCompared to a cube, a cylinder like our barrel sauna has less space to heat. Itโs an intuitive unit, from both the user and builder side of things.
โI like the simplicity of them and the fact that theyโre pretty easy to put together for people who want to have their own kit and build it themselves,โ he explains. โTheyโre very structured. Itโs amazing โ once itโs together, you can stand right on top of it!โ

THE FIRST WAVE
Getting started after the first prototype was no small feat, Luedtke shares. During the summer 2024 season, a considerable amount of interest bolstered their progress.
โI built a few more that summer, but in the winter of 2024, it really took off. I had more orders coming in at that point. This meant we outgrew our original garage, which was a 25-by-25-foot space. That works for a lot of stuff,โ he says good-naturedly, โbut not when the space is only big enough to fit two of the products youโre building.โ
In January 2025, the company moved to a historical (and much larger) warehouse in the small town of Mount Horeb, Wis., its current home.
Driving up to the shop is an immediate integration into the work that Luedtke and his team, including Ben Cameron and Julio Bustos, do every day. The LDB trucks flaunt their logo in the driveway, poised for deliveries. The garage doors are rolled back to show off the built-to-scale sauna, settled in its cradle โ a sneak peek to the product that completes the majority of their inventory.
โPeople come by all the time and ask us what weโre doing because they can see into our shop,โ Luedtke says. โItโs a huge space, itโs beautiful in there. Eventually, we thought it would be a good idea to just build one and keep it onsite.โ
A CHARMING COLLECTIVE
Luedtke is the epitome of an eager craftsman as he shows off his shop, explaining the stream-lined process and separate stations that go into creating the luscious product that so many customers rave about.
Between the three of them, Luedtke, Cameron and Bustos can build the frame relatively quickly and complete it easily in a single day. They can always ship the saunas on a trailer and drop them on the site, Luedtke explains, but he prefers being able to assess the site beforehand, in order to better fit the sauna to the surroundings.
โThere are other styles that might work better,โ he admits. โThere are experts in the field of saunas that might know the perfect dimensions, perfect angles, perfect conditions that make the best sauna. But the beautiful thing about our saunas is that theyโre working for us, and theyโre amazing for our customers.โ
One of the most enchanting things about the order of operations at LDB Sauna is the reality of having each product be built by hand. โWe have an eye for detail,โ Luedtke says. โWe donโt like to let many errors slip past, but itโs a part of the human touch. Iโm not here to scale and create a product that we can just get a machine to do. Having human touch as a major part of the process is the point.โ
Locally and almost completely handmade from a small business in a small town โ whatโs better than that?
โI feel like everybody who buys one of our saunas, in a way, becomes a friend,โ he smiles. โThis happens a lot. We spend a whole day at the customerโs property building it, so thereโs naturally some conversations that come out of it.
โAnd whatโs nice is that we can generally accommodate the specific requests we get,โ he explains. โWe do custom benches and other specific pieces to make the sauna unique to their wishes.โ
ROLLING INTO THE FUTURE
If his jump into building saunas in just over a year is any indication, Luedtke doesnโt shy away from new ideas. Instead, he embraces them and makes a plan to introduce them as soon as he reasonably can. Next up: a public sauna? A line of hot tubs? Saunas that can convert to sleepaways? The possibilities are endless.
Some of these goals โ like the use of a shared sauna similar to community pools in the summertime โ may take more time than others. But his determination bleeds into every word; given the right materials, he can build virtually anything.
โMy builder mind is going constantly. Everything Iโm looking at, I always think, โHow do I build this?โ A saunaโs just a large piece of furniture,โ he shrugs.
Itโs no secret that pride is woven into every part of LDBโs process โ into each cedar plank and each raucous laugh that echoes around the space; the culture in the shop makes that clear enough.
With big plans for the future and only one year under their belt, Luedtke and his small but mighty team are ready for whatever the coming years will bring. Theyโre making their mark on Mount Horeb and the industry, one sauna at a time.
