"From the craftsmanship to the customer experience we could not have asked for anything more. The team is incredibly knowledgeable & professional with extreme attention to detail. We absolutely love our sauna!"
"Northern Steam did a phenomenal job building an absolute dream outdoor spa for me! Every single detail is perfect. I am obsessed with my sauna and outdoor shower and have been using it every single day since I’ve gotten it!"
"We evaluated numerous local Minnesota builders and ultimately chose Northern Steam for their exceptional quality/craftsmanship and a custom model that truly fit our needs. The finished sauna exceeded our expectations."
"Even on a -14 degree windy day, it heated up quickly and held 190° with no issues. Fantastic build quality, great service, and overall I could not be happier."
"Last week Jaden and his team completed a perfect Northern Steam sauna two steps out my downstairs slider and under our deck. It heats up in no time at all. They do great work and clean up every evening before they leave."
"Jaden is a professional well beyond his years, offering impeccable response time and customer service. He consistently kept us updated, stayed perfectly within budget, and actually beat the estimated timeline."
"There were no high-pressure sales tactics or rigid packages; instead, the process felt like a genuine collaboration. They took the time to understand exactly what I was looking for and were completely transparent about every step of the build and the costs involved."
"Jaden and his crew took on a custom back yard sauna project that others said was too difficult and built us a beautiful sauna at a competitive price. 10/10 recommended."
"Northern Steam won out: their workmanship, customer service, and even price were great. Visiting their workshop and seeing a unit under construction is what convinced us. Within 72 hours, we were using a new sauna in our backyard!"
"Jaden with Northern Steam is a fantastic craftsman to work with. He takes the time to listen to your vision, offers excellent suggestions, and maintains clear communication throughout the process."
"We had Northern Steam convert our lake shed into a great sauna. Jaden and his team did a great job! Stayed within budget and finished ahead of schedule!"
"While he does a quality build at a competitive price, I mostly went with him for his responsiveness. Also, greatly appreciated that he had connections to do everything from building the foundation to coordinating the installation and electrical hook-up."
