Happy sweating!!!"

This is something we've dreamed of for years and my only regret is not getting it sooner! Also huge shoutout to Tyler and his crew-excellent communication, service, and all around such nice people. Thank you all!!"

"We were so fortunate to find Matt and his team at sauna supply company. My wife and I are novices to the sauna world, Matt and his team were incredibly patient and knowledgeable. They made sure we got just the right equipment. They went above and beyond what we were expecting. The Finnleo sauna equipment is fantastic with the wireless connectivity, integrated LED lighting. We couldn’t have had a better experience, and would highly recommend them."

"This company really knows what they are doing, we had 2 other companies we were considering but from the initial discussion with Sauna Supply to get a sense of what we wanted for our Sauna, their team was knowledgeable and answered all our questions satisfactory. The installation process was super easy and the finished product was quite impressive. I would highly recommend."
Nonso C.Google Business Review
"From start to finish, Matt and the install crew were great to deal with. We walked into the showroom with no ideas on what we wanted. Matt took the time to go through every option. He then came out to the house and measured the space, and gave us different design ideas. We have been using it for a month and love everything. The quality is amazing, and it turned out perfect."
Sarah S.Google Business Review
"As first-time sauna users, we couldn’t be happier with our new 5x7 sauna from Sauna Supply company! Tyler and the team made the entire process easy and enjoyable, guiding us through every step with expert advice. The craftsmanship is outstanding, and the sauna not only looks amazing but also heats up quickly and retains warmth beautifully. It has been a fantastic addition to our lifestyle, providing relaxation and wellness benefits we never knew we were missing. If you’re considering a sauna, we highly recommend Sauna Supply Company for their quality work and excellent service!"
Jesse G.Google Business Review
"One of the coldest weeks (highs below zero) of the year in northern Wisconsin, and Sauna Supply sent two crews to build my custom sauna on-site in a matter of days. This team has a ton of experience building saunas and have been incredible at every stage of the process. Great team of individuals to work with from design, to scheduling, to actual on-site construction. Very detail oriented and family driven, I would highly recommend this group of sauna enthusiasts and builders!"

Gary M.Google Business Review
"Wow! Sauna Supply was incredible to work with on my recent outdoor sauna build. They were super responsive, helpful, and understanding throughout the whole process. When I called they picked up or called back right away and knew my name! Great businessmen with great customer service who worked hard to help me start, build, and finish my project. I would absolutely work with them again."
D. K.Google Business Review
"My husband and I were impressed with all of the people we worked with from the Sauna Supply Company Co. Our salesperson Travis was knowledgeable and helpful from start to finish -including the purchase details, to scheduling and quickly responding to questions. The crew building our sauna including Travis' brother Cody were professional, friendly and efficient. We love the look and size of our sauna and haven't missed a day taking a sauna since we got it. Thanks to Sauna Supply Company working hard to get our sauna built before the snow flies - this winter is going to be a lot more fun!"
