Planning your installation?

Heat that goes deeper.
Two kinds of infrared heat and a ceiling of LEDs, working as one
-
UL-listed heaters that penetrate up to 25x deeper than standard carbon panels. Intense heat that reaches further, faster.
-
Carbon panels on both side walls surround you in 360° of steady, full-body infrared warmth.
-
Near-infrared LEDs overhead with different color settings and a slow color cycle. Set your atmosphere from the touchscreen.
-
Infrared warms you directly. The Finnish-built Harvia KIP 4.5 kW heats the air around you up to 190°F, and a ladle of water on the stones turns it to steam. Use one, or both.

Let customers speak for us
Sauna is amazing, easy to order, and got just what we ordered right on time!
The sauna kit is packaged perfectly with what you need first at the top of the pallet and the roof at the bottom. The build went smooth and it is a beautiful solid sauna. We couldn’t be happier with it.
This sauna is extremely well built and truly a pleasure to build. I received the measurements ahead of time and installed the foundation using pavers, topped with treated lumber. The stove is excellent… easy to make a fire and really heats up the sauna well.
Now… my wife and I are happy sauna people.

This sauna is amazing! In comparing different saunas before my purchase, this stood out for its high quality materials and great looks. I've been very happy with the it so far and the support from Premium Saunas was excellent
I've had my saunalife CL4G setup for a few weeks now. I actually put the sauna in my basement and liked it without the trim so I kept it plain. I've been using the sauna 3-4 times per week and absolutely love it. I have nothing but good things to say about this sauna and I was actually pleasantly surprised with the setup as many of the reviews had me concerned. Ended up taking me maybe a full day by myself but overall wasn't too bad.
Of all the people I spoke with the Premium Sauna team was most knowledgeable and helpful. They understood the tradeoffs and patiently worked though the different options with me. 1st class experience for a significant health purchase.
We Got the 3 person sauna, my husband and are pretty small people, about 5’ and 5’4” so this size fits the two of us very comfortably!
We got our sauna kit about 7 days after we ordered it. The shipping was great! The driver dropped it off in our garage so we didn’t have to move it from the curb!
We were so excited to start assembling it, we started at it right away. The building of the sauna took about 1 full day, from sun up to sun down! The directions got a little confusing in some places but we had watched a few videos prior to starting, of other sauna owners assembling theirs, and those helped tremendously.
We use our sauna every single night pretty much. Even as the weather is warming up, we still enjoy a good sauna sesh. And if we ever move from this house, we will absolutely be purchasing another one. Maybe a little bigger next time!
The setup was pretty straight forward and it’s made of high quality materials. Really enjoying the sauna!
Working with Premium Saunas could not be easier. Wonderful staff and knowledgable!! Shipping was good and build went pretty smooth. When we had questions they were on it with help! I fully recommend them to all of our friends!!!
We had a great experience with Premium Saunas. Our Dynamic Bellagio sauna was delivered on time by a great delivery driver. It took 2 adults about 1 hour to put together. It was very well packaged and arrived without any damage. Highly recommend!
After going the cheap route with an Aleko tub we returned that leaky thing and bought the SaunaLife Model S4. It came within a week, it was assembled and crated as described and I had it up and running the same day.
We had to move it about 100 yards into the backyard - two strong guys and PVC pipe to roll it on had it there in less than an hour. Pro tip - uncrate it, makes it easier. Assembly of the stove and chimney took another 45 min and filling it with a 5/8 hose took about an hour. Only thing that was a bit disappointing is that the holes for the chimney guide are not pre-drilled and the self tapping screws that come with it are not strong enough to drill through the stainless steel. You need to have your own metal drill bit for this.
Heated it and enjoyed the spring evening with the Mrs in the water.
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.
