A personal retreat

I have looked forward to having a real sauna so that I could use it frequently and hopefully get the health benefits by using it with consistency. Having had the Lennon Cube delivered to me in mid August, I found a competent carpenter to help me assemble the unit which took just under seven hours, The electrical work was done in advance and I finally took my first sauna in late August. I have gotten into an every other day schedule and the unit is a delight. I look forward to years of use and benefit.

Best purchase we've made in a while!

We've had our Backyard Discovery 2-4 Lennon Cube Sauna up and running for a month now, and I honestly can't say enough good things about it. We set ours up in the garage since we have some extra space and don't park our cars in there. After taking some time to plan the layout, make sure we had proper ventilation, and map out the right distances from the walls, the actual setup was surprisingly easy. The instructions were really well written and straightforward to follow. The build quality really impressed us, too. When our electrician came out to do the proper electrical hookup for it, he was totally blown away by the unit and how solid it is. It's been running flawlessly, and I've been using it almost every day. It heats up great and holds its temperature like a champ. Honestly, for what you get, the value is just unbelievable—I almost feel a little guilty when my neighbor comes over and checks it out! Thanks for making such a great product. Looking forward to getting years of use out of it.

Worth it

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.

Love this Sauna

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.

Good sauna so far

Just got my sauna installed. I have used is once and it heated up good but it was already pretty warm out. I don't think it would fit 6 people in the box maybe 4 people. I love the depth of the benches. I could lay down comfortably in top or bottom bench. The ladle is nice can't burn yourself because its so long. Love that

Good instructions - heats up quickly!

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!

Game changer

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

Great value, but needs some TLC

Sauna gets hot fast and performs great for the price. However, you have to work around some quirks with the heater controls. 1. Temperature sensor is not calibrated quite right, and the heater emergency shut off will turn off the heater early if you set it too high (keep is under 176F if it's humid). 2. Arranging the rocks so they touch the metal heater enclosure also usually makes the shut off trigger, so I keep limited rocks only in the center of the heater. 3. If the main power switch isn't reset regularly, sometimes the heater never turns off at the correct temperature, and once again the emergency shut off switch triggers. You have to completely turn off the main power and restart it, which sucks if you're in the middle of a session. 4. It does tend to collect water, so I would turn it on regularly if you have lots of rain or humid weather to avoid mold growth. 5. Wood warps when it gets wet and dries. Sometimes the door doesn't quite fit. For the price, it's outstanding, but don't expect a seemless experience.

great addition

I’ve been really impressed with the Lennon 2–4 Person Sauna. It feels super sturdy—the thick cedar gives it a solid, well-built feel and you can tell it’s made to last. Once it’s heated up, it holds temperature really well too. Honestly, it also just looks great in the backyard. The clean, modern design and glass front make it feel way more high-end than I expected. It’s one of those purchases that actually looks as good as it functions.

Easy to assemble

We did a lot of research before choosing the Lennon sauna, and the build quality truly stands out. The cedar construction feels durable and well-crafted, and the tongue-and-groove panels fit together seamlessly. Even the roof is heavy-duty, which is important being we live in the midwest with many climate changes.   Inside, it’s surprisingly spacious. Four adults can sit comfortably without feeling crowded. The benches are solid and supportive, and the heat retention is impressive thanks to the thick tempered glass door and tight construction.
