I love this sauna! It's perfect for 2 people (or 3, but 3rd person has to sit horizontally and be pretty small). It heated up to 210 degrees the first time I used it. I'm an avid sauna user and it was HOT.
I had my contractors put it together. The kit arrived in a palette with a delivery service about 10 days after I placed the order. It took my contractors 1.5 days to put it together, having never done one before and it looks great!
The configuration of how the heater sits is a bit weird with the Harvia "build in control" version because the knobs face the back of the sauna and you can't really see them and sort of have to guess what position the knobs are in. I almost regret not just buying the wifi-enabled, but money was hard to justify there.
Accessories: Thermometer works great. Only thing I don't like is the bucket and ladle. The bucket doesn't come with a handle, you use the ladles as the handle and it doesn't seem secure at all when carrying water. The ladles handle also gets extremely hot to the touch (hotter than the wood in the sauna) and you need to use a towel to use it. I'm going to shop for new accessories for sure, which is annoying, but for the great deal I got on this sauna, it was worth it.
I had the same sauna priced out by a local sauna installation company and they had told me $10k all-in for sauna, heater, installation. I did this for far less buying through Premium Saunas and using my own contractor. This website offered the best price and although I was a bit skeptical about the vendor and process for delivery, it was insanely smooth and a great deal!
