Sauna Wood, Thermally-Modified, Tongue & Groove, STS4 Profile, Nickel-Gap, Wall Material
Create a bold, contemporary aesthetic in your sauna with the Thermo-Aspen 1x4 STS4 tongue-and-groove profile. This premium wood, known for its straight grain, uniform texture, and warm golden-brown tone, offers a sophisticated appearance that complements any sauna design. With its ability to resist resin secretion, splintering, and overheating, Thermo-Aspen is an ideal choice for high-temperature sauna environments.
Thermally modified wood is crafted through an eco-conscious process utilizing heat, steam, and pressure. This natural enhancement improves the wood’s dimensional stability, moisture resistance, and durability, making it highly resistant to warping, decay, pests, and fungi. With optimized moisture content, Thermo-Aspen is perfectly suited for sauna applications, outperforming untreated wood.
The STS4 profile features narrow, angular grooves that achieve a striking nickel-gap appearance. This design brings a clean, modern aesthetic to sauna walls and ceilings. For a more dynamic visual effect, the STS4 profile can be paired with other wood profiles to create unique contrasts and personalized styles.
At Premium Saunas, we source only the highest quality Thermo-Aspen from trusted suppliers in Northern Europe and Canada. With over 55 years of experience, our team ensures every piece meets rigorous quality standards, delivering consistent, reliable, and beautiful materials to elevate your sauna experience.

Scandia Electric Ultra Sauna Heater - Large 18.0 KW
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.
So cute! Had first session tonight. Works great. So many rocks made for great steam - again and again!
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!
We received our sauna and set it up the same day. Took us a little less than 2 hours.
It’s been great!! We let it warm up for about 20 minutes then use it for 20-25 minutes daily.
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.
The sauna works great. Very easy to put together. The customer service was excellent!
Always wanted an outdoor sauna and the Grandby 3-person model seemed robust enough for our varied weather. It arrived promptly and to my surprise, setting it up was a breeze, had it ready in about 2 hours! It’s been our evening sanctuary since. Despite its easy setup, it's sturdy and heats up fast, making every session relaxing and rejuvenating. It's transformed our backyard into a year-round retreat. Plus, the customer service was genuinely helpful when I had a quick question about maintenance. A solid investment for home relaxation!
This sauna is great. Easy to operate and really durable. I use it all the time.
