Amazing sauna that I highly recommend

We ordered the 4 person barrel sauna and love it! We wanted a little extra space for the 2 of us/guests and it’s great. We could definitely fit 4 people in it if we needed. We use it every single day. It took about 10 weeks to get here because they build it specifically for the order. Putting the barrel together was fairly easy with 2 people. The electrical and the heater definitely required an electrician to install as we could have not done it alone.
We ordered the biggest heater (harvia spirit 8kw) and it heats up the sauna in about 15 mins inside our 40-50° garage. Overall this style of sauna is hotter and you sweat a lot faster than in an infrared sauna. I truly 10/10 recommend!
Pic is of us in the middle of building it.

Easy Assembly/great performance

Took me about 6 hours over 2 evenings to assemble almost all by myself. Had a pro run a new circuit from my panel. Very well made and assembly was straightforward. Heater is well sized and reaches operating temperature in under 30 minutes.

Salt panel is spicy nice

The salt panel was a great addition to our Madison Sauna. It has excellent grain which is accented by the amazing color lights that glow through the panel. Also when you hit the rocks with a splash of water you can feel the heat bounce off the panel. Great addition if you are considering this option.

Lane G. W.

Purchased a 2 person Almost Heaven barrel sauna and were delighted with the product. The order process was quick and easy, the sauna arrived on-time, installation was simple, following the provided instructions, and the sauna is extremely high quality. We’ve used it daily for over 2 weeks and quite frankly I don’t know how we lived without it. If I had it to do over again I wouldn’t change a thing... except maybe purchasing a 4 person model to easier share with friends!
