Highly Recommend This Company

The team at Soaknsweat was absolutely incredible. I honestly didn’t think customer service like this still existed. Kris and the crew actually answered the phone, patiently walked me through every question, and helped me make several key decisions for my sauna setup. They followed up quickly, were extremely professional, and truly earned my business and recommendation. Their YouTube content was also a huge help during the planning phase — and one of the main reasons I chose to order from them. Thanks, team!

Building Phase

I’m currently in the process of designing and building a sauna. After a lot of online research and frustration, I discovered Soak 'n Sweat — and it was a game changer. Their educational page covers every aspect of sauna design and answered nearly all my questions through detailed articles and videos. When I reached out via chat, Kris patiently addressed the rest of my questions without any pushy sales tactics. These folks really know their stuff, provide great products, and make the whole experience smooth and informative. Thank you!

I’m extremely impressed with their customer service and highly recommend Soak 'n Sweat to anyone looking for quality products and exceptional support.

This was my first time building a sauna, and I had tons of questions. Kris patiently guided me through everything — from venting and placement to the electrical setup. Thanks to the help, the heater installation went perfectly!
