  • Brian Morgan’s black shed-roof sauna with a large window, beside rose beds and stone steps

    “Gorgeous sauna! We love the modern look of black and big window. I was looking at a flashy one online when I was referred to Caleb. In the end, we got a taller unit, with a better rooftop and siding for our elements for the same price as an online one and a lot less headache with install. Recommend highly.”

  • Ryne Dougherty’s Model T with cedar and black siding and a wide window, on a concrete pad behind the house

    “I recently had Montana Sauna Company build and install their Model T sauna for our home, and I couldn’t be happier with the entire experience—from start to finish! The Model T is an absolute gem: perfectly sized for both solo sessions and having friends over, with beautiful craftsmanship using premium materials that feel built to last through Montana winters (and beyond). We added the salt light fixture as a custom touch, and it’s stunning—the soft, warm Himalayan salt glow creates such a relaxing, spa-like ambiance that elevates every session. The build quality is top-tier: solid construction, excellent insulation, efficient heating, and thoughtful details that show real attention to authenticity and durability. This isn’t some off-the-shelf kit; it’s a high-end, custom piece that delivers an incredible sauna experience every time. What really set this apart, though, was Caleb. From our first conversation, he was incredibly friendly, knowledgeable, and professional. He listened patiently to our ideas, offered expert guidance on customizations (including the salt light), and made sure everything fit our space and vision perfectly. Communication was clear and timely throughout the process and he even followed up afterward to ensure everything was working flawlessly and to share tips on maintenance and optimal use. His passion for saunas shines through, and he genuinely cares about making sure customers get the best possible outcome—it’s rare to find that level of service these days. If you’re considering a custom sauna, do yourself a favor and go with Montana Sauna Company. The quality is unmatched, and Caleb’s professionalism and friendliness make the whole process enjoyable. Highly recommend—worth every penny! Thank you, Caleb and the team!”

  • “We are thrilled to have a custom built sauna at our home, which was completed in early January 2025. From the first time we interacted with Caleb, he was knowledgeable, professional, and showed a great deal of passion for the project and the benefits of sauna therapy. Caleb finalized the build as expected, was timely, and communicative throughout. Caleb has become a friend of our family – hard to find that caliber of business owners. Caleb’s team (Bob and Dre) were additionally courteous, knowledgeable, and a pleasure to have around during the build. We have experienced firsthand the many benefits of sauna therapy, it has truly changed our lives for the better. We recommend reaching out to Caleb and inviting a sauna into your space – he is a true craftsman.”

The whole process will exceed your expectations and you will have a life changing sauna to use every day on your journey to health, wellness, and happiness.”

    Tony Eason · Lake Stevens, WA
  • “Caleb and Bob worked with my other contractor on a unique project that ended with using a giant crane to drop the custom sauna over the house onto its platform! From start to finish, communication was excellent and could not be happier with the end results. It’s a beautifully built sauna that works incredibly and using it 5-6 times per week. If you want a high quality sauna that will change your life for the better look no further than Montana Sauna Company!”

    Joey Kunkle
