We want you to feel good about choosing Sauna Marketplace long after your first session, and confident recommending us to a friend. That standard guides the advice we give, the products we sell, and the way we take care of our customers.

★★★★★
“The heater fits wonderfully in there and it looks fantastic. That Harvia Cilindro 9kW is incredible.”
Millie K. · Harvia Cilindro owner

★★★★★
“Perfect to protect the seats in our sauna..”
M. S. · Harvia Paraffin Oil owner

★★★★★
“Very happy with the M3. First off Ben did a great job answering all of my questions and walking me thru the best stove selection for my build. Shipping was fast and painless. The stove takes 30 minutes to heat up and doesn’t use as much wood as I imagined. I also purchased the heat shield for clearance and with the help of a friend install was quick and easy. I wouldn’t hesitate to work with Ben from sauna market place again. Cheers!”

“I couldn't be happier with the service at SaunaMarketplace, Ben was incredibly thorough with his service and expertise and guided me through every step of the purchase process.”

“First of all I want to say Ben was fantastic and very informative with all the products on his website. He recommended the Saunum Air and this was the best decision for my 6x8 ft 7 feet high cedar sauna. I got the 7kw with Wi-Fi and the power is plenty. I can take a dry sauna with no water on the rocks or add water and it becomes a steam room. The best part is when you turn the fan on and add water you can sit at lower level and not get too hot or cold. … I have been in saunas most of my life and Saunum changes the game. It is built solidly and pumps out tons of heat. I would recommend this unit big time Saunum hit it out of the park with the fan system. … Before you buy a sauna heater make sure you talk to Ben about this unit and the benefits.”
