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!

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

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

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

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

Honestly impressed with this sauna. The wood is nice and thick, so it feels solid and well-built, not flimsy at all. You can tell it’s made to last. What surprised me most is how fast it heats up — no long waiting around. It’s become my favorite way to unwind after a long day. If you’re looking for a durable outdoor sauna that gets hot quick, the Lennon from Backyard Discovery is a great choice.

Great sauna

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!

Overall a super unit!

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.

Amazing Find!

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.

Easy to assemble

Great structure, bad electronics. Not working after first day
