What our customers say
4.8 from 139 Google reviewsExtremely happy with our sauna from Cedar Sense. Extremely high quality product and everyone loves it. Mike provides unparalleled customer service and it’s worth every penny to go with him. I can’t think of any other company that I can call the owners phone and he picks up and answers my questions. Outstanding experience from beginning to end.
4 Person Barrel Sauna For Sale
Great customer service. The owner called me up and took good care of me. Rare in today’s world. Highly recommend. Thank you Mike.
Peter Ahlers-Nelson
Mike with Cedar Sense helped me get set up with an absolutely beautiful 6 person barrel sauna. We live in the mountains and opted for the iki wood heater and a big window to enjoy the view. The build construction was high quality. I had seen multiple other kits and barrel saunas and this one was over the top in being well made. We chose a metal roof due to the snow load as well. Mike delivered it and set it up perfectly on our back deck. The whole process was seamless and his communication was great. I would strongly recommend using Cedar Sense. In addition, he is always around and helpful for questions and anything else needed.
Brian Unterman
Mike … the owner is ‘amazing’ to work with, helpful, responsive & very knowledgeable. The ‘hot tub’ itself is attractive to look at, has a very efficient wood burner (WOW) & feels good size & shape wise when you are in the water. I’m very pleased. Tim

Thank you, thank you, THANK YOU!

Cedar Sense was great to work with. They provided us with tongue-n-groove planking, glass framed entry door, sized & provided the sauna heater while promptly delivering our order. They also answered numerous questions while offering lots of free sensible advice. Highly recommend you reach out to Cedar Sense for all your Sauna needs.

Couldn’t have asked for a better experience. Micheal is a top notch guy, spent all the time on the phone with me to not only give me information and insights on the saunas but also ideas that could help direct us and our business in the right direction! The sauna was bigger and more impressive than I would have imagined! So pleased with our purchase!
