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!

If you read the other reviews, then you will see and hear that this a great product. From purchasing, shipping, receiving, and instructions were great. Building it was great, you just have to make sure you read and look at the instructions. There are only 3 things that I say could be better. 1) The 120v light outlet should be incorporated into the control box. I feel this is an oversight here. 2) There should be a locking mechanism for the door and not just magnets to hold the door closed. This is fine in low wind locations or for people that do not have little kids. I think this is an oversight as well. 3) There needs to be a pan for water collection under the heater. When we first used it, I sat on the lower seat and found the hot water splashes on your feet. Yes it was hot!

We have had our Lennon sauna for 2 weeks now, and we have been in it almost every night!!!! My husband and I have an urban farm stay & farm experiences, and we wanted a sauna to not only help with our own health journey, but to also share with farm guests in the future. We loved the Lennon with the porch for its glass door so we could view the animals, the cedar looks and smells amazing, construction is solid! It took us about 10 hours to assemble, very clear instructions! The design is well thought out, and stunning in person. We've already had many farm guests asking about it, and commenting how nice it looks. We loved that the steel roof was included cause ours is outdoors. Has been heating up very quickly! Just overall impressed, and happy with our choice!

The Lennon outdoor sauna is super well-built and heats up way quicker than typical models. The cedar construction looks great, smells amazing, and holds heat really well, and the sturdy steel roof feels ready for any weather. The Wi‑Fi control is a game changer—you can preheat it from your phone—plus the steam bucket, ladle, and dimmable lights make every session feel authentic and relaxing. Assembly is straightforward app, and the 5‑year warranty is a nice confidence boost. Overall, it’s a premium, easy‑to‑use sauna that feels thoughtfully designed from top to bottom.

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.

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.

This 4-6 person Lennon sauna is amazing! This is the second item I have purchased from Backyard Discovery, and both items have exceeded our expectations. It looks great from the outside and is super spacious and comfortable on the inside. This sauna has some nice features to point out: adjustable  lighting on the inside, heats very quickly-which you can warm at any time with the bluetooth feature. The quality of the wood is very durable and thick. I would give it a ten out of ten. Upon arrival it came with very clear easy to follow directions. We also decided to stain the cedar to match our house, which is a really nice option with the quality of the cedar. The customer service was impeccable. They are available to help with any questions you may have. I highly recommend this sauna!

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.
