A handcrafted lakeside sauna built

Eagle River’s 8×12 Custom Sauna

In northern Wisconsin, where quiet forests meet cold lakes and winter lasts just a little longer, a sauna isn’t just a luxury—it’s part of the rhythm of life. This 8×12 custom-built sauna in Eagle River was designed as an extension of that rhythm: a warm, glowing retreat steps away from the client’s home. Crafted with intention, styled to match the existing architecture, and powered by an IKI wood-fired stove, this sauna captures the spirit of the Northwoods while giving the homeowner a sanctuary built for generations.

Inspired by the Surrounding Home

A sauna created to belong to the property, and to the client’s lifestyle.

The client wanted more than a standalone building—they wanted a sauna that felt like it had always been part of the property. The design direction was clear from the start: match the existing home and garage with precision. Using LP SmartSide exterior cladding, we mirrored the textures, lines, and colors of the main home, creating a cohesive visual flow from house to sauna. Combined with a reliable wood-fired IKI stove and future-ready electrical wiring, the build balances tradition with thoughtful planning for what’s ahead.

  • Listen to Your Body: If you feel uncomfortable, exit the sauna! It is better to prevent than to cure.
  • Stay Hydrated: Drink water before, during, and after your sauna session to replace lost fluids.
  • Session Duration: Two to three sessions per week, each lasting 15 to 20 minutes, is a decent start.
  • Sauna Etiquette: Shower before entering, dress lightly or with a towel for comfort, and keep talking to a minimal for a peaceful atmosphere.

The short answer is yes—with some restrictions. Saunas generally promote weight reduction by sweating, which allows the body to shed water weight momentarily. During a typical 30-minute sauna session, you can lose roughly 0.1 to 0.6 kg (0,22 to 1,32 pounds). However, this is primarily water weight, which will return as you rehydrate.

For more information on this issue, please see “Do saunas help you lose weight.”

Sauna bathing offers numerous health benefits, including weight control, hormonal balance, cardiovascular health benefits, musculoskeletal pain relief, muscle pain reduction, respiratory system benefits, and relaxation. It promotes a deep state of relaxation, reduces stress, and improves overall well-being.

Sauna baths are safe for most healthy individuals, but precautions are needed for those with specific conditions like acute infections, heart problems, or fever.

A Personal Experience

Finding Resonance

In the world, everything has a resonant frequency. From a board, to the engine in your car. We’ve captured this into instruments such as the marimba. A simple line of wood specifically sized to create notes. That note harmonizing perfectly with each other piece of wood comes together into beautiful music when played skillfully. In sauna design, we feel the same. Bringing together finishes, materials and textures that harmonize together to create a masterpiece. Perfectly tuned to your goals, the end result is a warm inviting space that doesn’t distract, but guides you into the relaxation of sauna.

"Working with Jayson and BW Sauna Co was a stellar experience in every way. I opened Seaside Sauna in Port Townsend, Washington at the end of May and every single person that enters the sauna says, WOW. I recommend working with BW Sauna Co to anyone who will listen."

Karyn Stillwell · Seaside Sauna, Port Townsend WA

"Jayson was professional, knowledgeable, and realistic about the steps needed to resolve the issue. He never tried to upsell us on products or repairs we didn't need. We wish we had begun our sauna journey with them from the start."

Stacy Crawford · Sauna Service and Troubleshooting

"After getting designs from a number of builders for a commercial use sauna we chose BW. Our running cost is well below what we were anticipating because the sauna runs so well. All of our guests, including some of Finnish heritage who grew up with sauna, have been impressed with the heat."

Shawn S. · Commercial Sauna, East Coast Delivery

"I've worked with a lot of sauna builders over the years. Their saunas are beautiful, built to last a lifetime, and reasonably priced. You simply will not find a better value for custom sauna and mobile sauna builds."

John Pederson · 612 Sauna Society, Six Builds

"Comparing BW to other mobile sauna manufacturers, his price is fair but the quality exceeded expectations. Thermally modified aspen smells nice and doesn't get hot. I'll be buying another mobile from BW in the future."

Brian Anderson · Mobile Sauna, Surfside Sauna

"Jayson and his team did an incredible job. They drove 27 hours from Minnesota to Arizona to deliver and install the unit in my spa. My customers are blown away and so am I."

Luke · Commercial Spa Installation, Arizona

"The woodwork is impeccable, the attention to detail in the construction is evident and the sauna fits perfectly in my backyard. It has transformed my outdoor space into a personal sanctuary that I look forward to visiting every day."

Andrew Burch · Custom Backyard Sauna

"This summer our sauna developed a few bulging boards and BW scheduled us in, came out and made the repairs, standing behind their work. This company is just awesome."

Niles Deneen · Custom Sauna, Minnesota
