Assembly

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!

Amazing Sauna

backyarddiscovery.com

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.

Very Happy!

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!

Farm & Sauna=Udderly Relaxing

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!

Great product and great support

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.

Great Vibes

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.

great addition

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.

Good Looking

Virtual 3D instructions are the best thing ever invented !!!! Super easy to follow. Love the fact that it highlights all holes and small details so it makes installing easy

Amazing

BILT

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.

Abysmal assembly scheduling.

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.
