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

Love! Mike did a great job walking me through picking the right sauna for our wants, modifying the benches to allow for hot yoga and delivering and installing for us! Cedar Sense knocked it out of the park for us and we could not be more happy! This sauna will be perfect for our whole family to use, to refresh relax and enjoy together! Thank you, thank you, THANK YOU!

Mike is such a great guy! Checked out his shop and products and enjoyed a fun coffee drink at Boozhi Brew. His saunas are beautiful and we are already trying to figure out a good time to use his portable sauna rental. Highly recommend!

PROSAUNAS Framed Sauna Window 16″ x 30″
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.
Dan Markert
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!

Common questions
Can I use infrared and steam at the same time?
The FD-5 Trinity gives you both in one room. Use the infrared heaters for a dry, gentle session, or turn on the Harvia heater and pour water on the rocks for traditional steam. Check the manual for running them together.
How long until it ships?
This sauna usually ships in 2 to 4 weeks. We confirm the timeline when you order and contact you before delivery.
What electrical does it need?
It depends on the model, so check the electrical line in the specs above. Some plug into a standard household outlet, while larger saunas need a dedicated circuit installed by a licensed electrician.
Is it hard to put together?
Indoor saunas ship as panels and most owners assemble them with a helper. We can also assemble it for you. Call or text 218-760-2041 for a price.
Can I pay over time?
Yes. Choose Affirm or Klarna at checkout to split your order into monthly payments, subject to approval.
What about the warranty?
It's covered by the manufacturer's warranty. You don't have to deal with the brand yourself. Call us and we handle the claim for you.
Still have a question?
Mike answers calls and texts himself.
