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!

I spent a lot of time shopping for a sauna when we were ready. Came across backyard discovery in my search and initially was skeptical, because there are a lot of companies that are "faceless" and once you buy the thing, you'll never get support again. I reached out and was pleasantly surprised to find people immediately available to help me, and also to find that this is a company that has been around a long time. Pulled the trigger on a REALLY well priced sauna. Showed up fast. I took my time building it, and everything went together super well. Especially happy with the included metal roof to protect the top from the elements. Heater is very nice, heats the sauna to 150 in like 15 mins right now. I oiled the entire thing on the exterior with paraffin oil, and did the benches too. We've been in it every night since I finished building it and we're very happy with the purchase, and with Backyard Discovery's service thus far.

Such a great sauna. The ability to turn on by app and fast heat up time are great features. A straightforward build - the instructions and app make it really easy to follow. It took me one full day with a friend. The wood is great quality and holds the heat really well. Highly recommend!

I purchased the 4-6 person Backyard Discovery Lennon Outdoor Cube Sauna and we couldn’t be happier. It has so many cool features and works great! The inside has plenty of room to stand up with two benches to sit down. The wood feels much more premium than other saunas in this price range. I am excited about how fast it warms up, which is great for spontaneous sauna sessions. Great investment!

I’ll be honest, I wanted something that felt solid—not one of those flimsy kits—and the Lennon 2–4 Person Sauna delivered. The thick cedar construction makes it feel really sturdy, like it’s built to last, not something I’ll be replacing in a couple years. Once it heats up, it holds temp well and just feels like a quality setup. It also looks sharp. The modern, clean design and glass front give it a high-end feel without being over the top. It fits perfectly in the backyard and doesn’t look cheap at all. Overall, no regrets—solid build, great look, and does exactly what I wanted.

Have had the unit about 2 weeks and use it every day. Its awesome! The delivery was a little wonky, but they were nice. Came extremely well pack and organized. No missing or broken pieces. Instructions were pretty good, I think we few things would be quicker to double up on a few steps. The digital version is slightly different than the printed I noticed. The seat bottom board is tricky to line up. As others noted, the flashing is next to none. While the rain stays out of the roof, it runs off the edge into the trim pieces which then runs inside the unit. Not bad, but not great either. I intend to fix it like the other poster mentioned with black flashing from HD. The quality is amazing for what you get. It heats up at 45 degrees to 180 in about 15m or less. I would say its not a 4 seater, more like 2 and 3 if you are friendly. Be cool to have an upper seat bench and lower to take advantage of the heat higher and cooler lower. The lights are great, although I wish it was built into the unit, even a separate button to turn on/off/dim. The little remote I know is gonna get lost or fail. The keypad takes a bit to get used., Its slow. Im on my second one and its better but not great. They sent a second one out immediately when I asked a question, swapped and it seems better. Im not sure if its related but the first keypad my wifi kept dropping and with the replacement it hasnt dropped once. So Im not sure? The app works great. Again.. one touch to power on.. wait for it to respond. Then timer.. wait. and go! Its a little learning curve, but fine. I had an electrical question that was awkward. It calls for 50amp circuit, but only requires 6awg wire. The book calls for 8awg. My electrician was battling me. We ended up with 8awg and it works fine. You need the neutral wire to power the touch panel. This was 14awg, I used 12awg. I mean, if you are going to put a neutral in there to step down the power to the touch screen, might as well power the LED lights as well right?! It cant be that much more to figure out that to simplify so you dont havent to run a separate 110v extension cord for the LED lights. But really, end of the day, its great with some minor tweaks. Get one and enjoy it!

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.

I paid to have it assembled and it’s got multiple defects, gaps and the installer is very shady and doesn’t respond to text as he’s not finished the job. It also took 2-3 weeks sitting in boxes getting weathered but it was covered by me. I called Sam’s Club several times which they contacted Backyard Sauna which put a little pressure on the installer and he came out. He gives you a date and time and never shows. His excuse was he had another job. Terrible experience and poor customer service.

Very poorly built sauna. The heater trips every time. I have to reset it. The one bench with no back rest sits at the bottom instead of half way up. Three internet connection doesn't work. The timer button on the LCD screen is broken. If it rains, the door warps soo bad that it doesn't fully close. No matter how many times I call support, and rearrange the rocks it still trips.

I cannot properly review the sauna itself because I have been unable to get it installed despite paying for installation service through Sam’s Club. The sauna was delivered and left sitting in my driveway, but nobody contacted me to schedule installation. I spent over an hour on the phone being bounced between Sam’s Club, Angi, and Backyard Discovery trying to determine who was actually responsible for the install. Eventually I was told that Backyard Discovery assigned the job to a third-party vendor, but nobody could provide me with an installation date or direct scheduling information. Meanwhile, the large crate is still sitting in my driveway creating HOA concerns because it cannot remain there indefinitely. At this point my frustration is not with the sauna product itself, but with the complete lack of coordination and communication regarding the paid installation service. If you purchase this product with installation included, be prepared for possible delays and difficulty getting clear answers on scheduling.
