This truly is a sauna for Finns

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!

Great product and great support

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!

Farm & Sauna=Udderly Relaxing

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!
