  • Go to “Wi-Fi settings”.

  • The SIM card and sauna will be online in 30 minutes. The sauna will not be online before the user account is connected to the sauna.

LOVE my Huum heater. BsaunasUSA was the only company that got back to me in a timely manner, and once I found their website I got my heater purchased and they shipped within a few business days. Very happy camper, two thumbs up

Very professional crew, knowledgeable, punctual.They did help with all technical aspects.We did build nice sauna last fall, that turned my winter in to one of the best I ever had - some times 180 inside and when you step out to 0 that unbelievable feeling.We did use it through January lockdown twice a week and I love it.Thank you guys for your support, quick response and help throughout the project.

10/10 recommend the best quality on the market hands down. I just bought one for my house and let me tell you everyone needs one of these.

Ordered Grill’D wood fired stove, pipes, glass sauna door and other necessities from Bsaunas USA. Couldn’t be more happier with quality of the products. World class customer service!! They are always available to answer questions despite time difference between East and West coast. Also got free consultation on how to properly do sauna ventilation(yes, there is such thing, very important). Definitely recommend, if you are looking for sauna products or services!!!

This is the most fun we've had in awhile! We rented it in the middle of the snow storm and it was amazing. Alternating hot sauna and cold snow was a must! The sauna is incredibly well-built, fits easily 6 people or even more. Not only did adults thoroughly enjoyed the sauna, the kids loved it too. We were having such a blast, nobody wanted to go to sleep!Alex brought the sauna and set everything up. It was super easy to operate and use. Excellent service overall. Highly recommend! We felt incredible afterwards.

Alex is the best. Answers calls, returns emails, gets stuff delivered, and the stoves are awesome. I purchased the 9kw wall mounted drop and couldn’t be happier with the purchase.

I am so happy to find such a knowledgeable and local distributor of the HUUM sauna. Alex was very responsive and went the extra mile helping me with my sauna. I’m so happy to have a HUUM sauna working during this cold winter.

Top quality products. Alex @ bsauas was super helpful and met my every need. I vetted 4 different companies before settling on bsaunas for my precut 6x5 sauna kit. Very happy with my choice! The clear cedar tongue and groove, 2x4 bench wood, and the trim boards i received were all by far the most beautiful wood I have ever seen. There was a problem with the original 2x4 bench boards i received (they were the incorrect length), but I called Alex and within 4 days I had the correct wood at my doorstep no questions asked. Excellent experience overall.

Great experience, great Sauna, Alex and his sauna is just wonderful. We rented this Sauna on wheels in early November 2020. Had it for two evening, weather was chilly (which was perfect for cool downs) and the wife's stress level dropped significantly. Let me tell you, that alone was well worth the rental price.The amount of cleansing heat and steam produced by this unit was amazing! If you are thinking of buying a sauna, Alex is your guy. Very knowledgeable, very thorough, quality build with quality materials and a warm and welcoming personality.The stove was very easy to use, all wood was provided, cut perfect to size and well seasoned. No sizzling from wet wood here, which made lighting the fire a breeze and kept the temperature blazing hot. Alex also provided a torch which made managing the stove even easier.The kids really enjoyed the sauna also. Ages 13, 11, 8 and 5. They didn't stick around long when added water and blasted the steam, but they still had fun getting their sweat on :-)We had some discussions about buying a sauna in the future (mostly my German father-in-law whom REALLY enjoyed the sauna also) and Alex ran us through his website. You can pick just about anything, any size and with the option to self install or have them do the build. Again, quality product and you will be very impressed.10 out of 10, would rent it again, and if you are thinking about buying, these are your guys.Thanks

Đ’saunasUSA is highly recommended seller, excellent top notch customer service and quality product! We could not be more happier with our new sauna! It is truly a piece of art, and place where we unwind, relax, and recharge. The smell of fresh cedar is so aromatic and woody. Shipping was fast, and installation quick and easy.

We had wanted a sauna for quite some time. Getting a little older and have read all the benefits, health wise. We thought it would take a while to have it set up so we put it off way too long. After speaking with bsaunas we were assured it is a quick and easy process and they made us feel at ease by answering all our questions. Believe me we had a lot of questions ha maybe too many but they were patient. We were using it in no time. Personally, I feel so much better after sitting in the sauna. I am blessed to have family that can enjoy it as well. It’s probably the nicest place at our home. We love it! I usually don’t post reviews but it’s helped us so maybe I can just pass it on to others. It’s such a great improvement in our lives. Thanks y’all!

We are beyond happy with our sauna, it looks amazing and functions perfectly. Alex and Costa were professional and installation went smoothly with everything cleaned up when they were finished. The wood burning furnace is super easy to use and is better than any electric heater I have seen (thank you Alex for talking us into going in that direction).
