I am a Finn so I have been to many saunas in Finland, electric, wood burning, smoke and I have to say I am impressed with the Lennon sauna. Assembly was easy, instructions logical, everything in the design was great and it looks beautiful. I stained it outside to add to weather proofing and to better match it with my house. Yesterday was time to test it. I was surprised how fast the sauna heated. I set it to 80C and it was plenty to give nice and crispy "löyly". I feel like a real Finn again!

Bought this a few months ago. This product is amazing. It took some time to put together but it was worth it. We leave in Michigan. so we decided to put ice guard on the top before we did the metal roof. We also had to caulk around the metal roof and wood edge. Now we have absolutely no water leaking in. There is definitely extra cost but for us it was worth it.

I bought the Lennon 2-4 person unit a month ago and have made sauna sessions a daily routine. I have loved my experience with our sauna unit and would recommend. We had on part missing from our kit upon arrival and BYD was quick to ship the replacement part within a couple of days.

I bought this a month ago and have used it consistently since then. Set up is very easy and they did a great job with the instructions. No missing parts, easy to follow, and the pre-drilled pilot holes were surprisingly accurate. As far as using it: Heats up very fast and maintains heat well; I love being able to use an app to turn it on from the house but the app (Tuya) is just awful. Perhaps they could use a different 3rd party app. Also the touchscreen interface that sits on the exterior is borderline useless. The touch is so non-responsive that its as if its broken. Also, you may want to put a cover over the screen so that it is not burned by the sun. Overall, still 5 stars. But this company needs to hire an interface designer next time they attempt a control unit..

I've had this sauna up and running for about 3 weeks now and absolutely love it. I decided to build it myself and had it completed in a little over 10 hours. It would have definitely went quicker with 2 people but it really wasn't bad at all and the instructions on the app are easy to follow. The only negative I've found was the heater would trip the overheat switch if I turned it on to heat to 194 but since switching to heating up to 176 and then increasing heat from there it has helped eliminating it overheating on the initial warmup. I would highly recommend this product as well as Backyard Discovery

We ordered this sauna for our Airbnb property and it has been great so far! The setup took 12ish hours with two people. The instructions were helpful. I would recommend having a rope for putting it together. We didn't and it made it tricky to get everything aligned up top. The sauna heats up very quickly and we are happy with the purchase!

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.

This Backyard Discovery sauna exceeded all of our expectations. The thicker wood frame and panels set it miles apart from cheaper saunas we considered. It feels solid, smells awesome, is well-made, and honestly was easy to build. It heats up fast, even on chilly mornings, which has made it an everyday favorite for our family.

What impressed me most about the Lennon sauna is how well everything works together. From the structural components to the heating system, it’s clearly engineered as a complete system. The smart control panel is intuitive, and the ability to adjust temperature and lighting easily adds convenience. The steel roof and durable materials make it feel built to last for years. It’s spacious, comfortable, and aesthetically stunning. This is a five-star product in every sense.

The Lennon 4–6 Person Sauna exceeded is perfect for what we were looking for. The design alone is stunning, the modern cube shape with rounded corners makes it look like a luxury spa feature in our backyard. The heater is incredibly efficient. It heats up noticeably faster than other saunas we researched, and the heat distribution is even and consistent throughout the entire space. The cedar interior smells amazing and feels solid and high quality. The Wi-Fi control is a huge convenience. Being able to preheat it from my phone means it’s ready when I am. The dimmable LED lights create a relaxing atmosphere, and the included bucket and ladle make the steam experience feel authentic. The craftsmanship is top-tier, from the tempered glass door to the sturdy steel roof. This is a premium product through and through.
