Let customers speak for us
Assembly easy & quick with 3 people. The glass front is VERY HEAVY @ #220 and large. Does fit through standard door. Heats well, looks great. The temperature gradient is pretty steep so I did insulate the top. Wiring the 8 Kw heater was tricky as internal bridging was required. Would buy again, good value excellent product.
Setting up this sauna was challenging-definitely follow the directions closely. A video tutorial would have helped, but the end result is worth it. The sauna looks fantastic, adds style to the backyard, and is spacious enough for four people. The quality materials and design make for a comfortable, durable experience. If you're ready for a bit of setup effort, this sauna won't disappoint!
We are so glad we purchased this sauna. It's the perfect size. And I love the red light.
Easy to use touch panel gives complete control throughout the sauna experience
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!
My wife and I have been enjoying our new Venice Elite sauna for several weeks now. We have added a 30 minute sauna into our excercise/wellness plan. We enjoy a relaxing sweat while listening to music, podcasts or just meditating.
The sauna was delivered exactly as explained by your team. It was well packaged with no shipping damage. The freight company unloaded the pallet at the end of our driveway and we were able to easily unpack the various boxes and move them into our basement individually. My wife and I assembled the sauna in about an hour without difficulty.
We highly recommend this sauna and will enjoy it for many years to come!
5 stars all around. The amazing personal custoner service, the quality build of the sauna. I don’t know where to start. I am obsessed and I’ve had it for a few weeks now. Best investment. If you’re on the fence, just do it!! You won’t regret it!!
I absolutely love my sauna. Super quick delivery. Sauna was put together and ready to go after about an hour of unpacking. I drive long commutes into work and have developed low back pain. After a week in the sauna the back pain is gone! I absolutely love my sauna.
I ordered this sauna late on a Sunday and received it 4 days later. It was in perfect packaging with no damage. The sauna was a great price and is wonderful! The communication via text with Premium Saunas was great. I will attach photos. We converted a small ugly storage room off our garage into a sauna room. This will definitely improve our resale value of our home. Thank you for the speedy delivery and for it arriving in perfect condition.
Got my HUUM Drop 9 from Premium Saunas and their team was awesome. Helped me pick the right model for my space and provided assistance with some small issues. The heater itself is a beast! looks cool, heats fast, and holds temp really well. Couldn’t be happier!
Wasn’t sure how much we’d use it, but now it’s part of our routine. Premium Saunas was great, helped us through the whole process. Solid build, heats up fast, and smells amazing inside!
Love this sauna. I use it almost every day after work and its just so relaxing. Heats up fast and gets nice n hot. My only regret is not getting one sooner.
Never owned a sauna before, so I wasn’t sure what to expect, but I’m officially hooked. The heat is strong but comfortable, and the design is stunning. We’ve had friends over, and now they all want one too!
Was looking for a compact but powerful heater, and this one delivers. Super efficient, heats up fast, and the stone capacity makes a huge difference in how the steam feels.
The buying process was smooth. I was expecting shipping to take longer but it arrived in just about a week, well packaged and no issues. Works amazing! The heat is even and lasts a long time. I also gotta say Premium Saunas was really helpful when I had a few setup questions. Would definitely buy from them again.
