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!

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 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.

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!

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.

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!

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 absolutely love our Backyard Discovery 4–6 person sauna! Compared to competitors we looked at, the wood in this sauna feels much thicker, more durable, and clearly built to last. I workout all the time and cannot wait to use this after my workouts. It heats up noticeably faster than other models we’ve seen, which means less waiting and more relaxing. Plus the bluetooth and adjustable light feature allows me to set the temperature and lights ahead of time. We already have a Backyard Discovery gazebo in our backyard, which is incredible. We continue to get rave reviews on the gazebo and now I know we will get the same on the sauna. The quality of this sauna lives up to the same high standard. If you want a well-constructed, efficient sauna that feels premium at every touchpoint, this is it!

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.
