Testimonials

Just wanted to thank Tim and Alex for the help in replacing my 20 year old sauna heater. They even went the extra mile to get me the upgraded color option.

We are completely new to saunas but want the health benefits so we reached out to Finnish Sauna and found experts! We don't have our sauna yet but are confident we have ordered what is best for us with Tim and Alex's help. Thank you gentlemen!

Very helpful ordering staff, especially Tim and Alex. They also checked on availability and provided good advice on features and other support available. Once we got the sauna, setup was straightforward. The HUUM heater and controller we installed didn’t seem to heat well initially and took a long time to heat. But with excellent advice and support from Alex (including a replacement controller which turned out to not be the problem) we were able to solve the wiring issues and now have the sauna we have dreamed of. Thanks to all at Finnish Sauna Builders from a Finn in the Pacific Northwest!! This is a very strong company who all stand behind their products100%. Thanks!

Messaged them on their website on a Sunday not thinking anyone would be available to help. To my surprise Tim responded so quickly I thought it was a robot! Tim was able to help me make a decision on what heater I needed. 100% recommend.

Building my first sauna and I went down the internet rabbit hole, purchased books etc. I wish I called Tim at Finnish Sauna Builders first. His knowledge was tremendously helpful. He was patient, answered all my questions and then some. I ordered all the materials from him. I could not be happier BUY HERE AND DEAL WITH THESE GUYS!!! YOU WILL NOT REGRET IT!!

Alex was super responsive and provided valuable insight and support in my sauna decision. I've interacted with a number of different sauna companies and the crew here stood out above all the rest. Many thanks to Alex and team.
