Powered by our proprietary PrairieFire 9kW electric sauna heater, it reaches your perfect temperature 50% faster than 6kW heaters. Crafted from durable, decay-resistant cedar with precision tongue-and-groove construction and a thick 8mm tempered glass door, this home sauna delivers superior heat retention and consistent warmth. The robust powder-coated galvanized steel roof provides all-weather protection, while the natural aromatic cedar interior enhances every session. Between sessions, the covered porch with built-in bench seating lets you cool down and keep essentials within reach. The integrated smart Wi-Fi control panel lets you preheat your backyard sauna from your phone, so it's perfectly warm the moment you step inside. Experience the authentic Finnish sauna ritual of pouring water over heated stones with the included bucket and ladle for gentle bursts of steam, while the dimmable interior LED lights create the perfect ambiance.

Built with premium materials and backed by dedicated support, the Lennon cube sauna delivers a complete experience without compromise.
When choosing between a barrel or a cube sauna, I opted for the cube because the two-tiered bench seating really appealed to me. It is a completely different level of heat on the higher bench! Also, having recently burned my arm on the heater in a small barrel sauna, I wanted to make sure that there was some distance from the heater if we chose to fit a few people in there. You really easily could fit up to 6 adults in there, but two people with each person having an entire bench to lay on is a peak spa experience.
I assembled the sauna myself which took several days at a few hours at a time. I am a contractor, so I have tools that made the process straightforward. I personally found the assembly difficulty level low, but long. The product is shipped in several boxes which are not filled in any kind of chronological order. Each piece or bag of hardware has a numerical code on it. The instructions state to lay out all of the material in order to make it easier to assemble- but even doing so, much of the assembly time is spent trying to identify each part and making sure its the correct one. Again- not difficult if you are familiar with assembling things, but tedious.
The heat output is insane! I typically set it to 160/170 and could not imagine going above that- though you certainly can.
As others have stated, the wifi connectivity/ Tuya control app are not the best. The touchscreen control panel on the unit is also pretty bad. I almost completely avoid using the control panel and use the app to turn it on, but if you are not >10ft away from it, it usually has a connection error. To me, it's not a super big deal, but it can get irritating. This is the only reason for 4/5 stars.
It has only been a few weeks and we are using it almost every day. It heats up very quickly, and I'm anxious to see how it performs in the winter months.. Specialmildsauce. New Jersey. Sat Jun 27 2026
