Tikkurila Supi Black Sauna Wax (0.9 Liter) is a water-based, natural wax treatment developed to enhance and protect interior sauna wood while achieving a refined, contemporary look. The wax penetrates deeply into the surface, forming a silky matte finish that repels moisture and resists dirt without obscuring the wood’s natural texture. Its modern black color adds depth and contrast, making it perfect for darker, design-forward sauna spaces. Suitable for benches, paneling, ceilings, doors, and window frames, this eco-friendly formula is low-odor, fast-drying, and easy to apply by brush or cloth. The result is a durable, easy-to-maintain surface that combines aesthetic appeal with long-term protection in high-humidity sauna environments.

- DSDavid S.Verified BuyerRated 5 out of 5 stars7 hours agoNot just wax!
Bought the 2-person sauna for my wife to replace a very old hot tub surrounded by the deck. It went together flawlessly, with great instructions and all parts well labelled. Was impressed with the quality of fitting (and I've been making fine furniture for many years). I had to switch the door from the left to the right for the situation, and there were no problems. The 2 extra rails that were provided were not needed in my case, but allowed me to make an inside step and outside finials (with copper tops). I put a cedar shake roof over the provided rolled roofing. I used the wax to seal the floors and seats, and it went on easily. The pictures show the sauna from the upper deck and from the ground. The third is the view out the window. Looking forward to the first snowfall!
- BDBradley D.Verified BuyerRated 5 out of 5 stars1 month agoGreat protection for a basswood bench
My local lumber guy had a bunch of basswood sitting around. So I used that for my interior. I love that it is very light and it makes for a very cheerful sauna experience but being a lighter wood it does require some protection from staining. Supi Clear Sauna Wax is ideal. Goes on easily and is a breeze to clean up afterwards.

The sauna was arrived on time and we already have applied it. It is a great product and we noticed a difference right away. Highly recommend ordering from The Sauna Place and using this particular product for your sauna!
- NSNancy S.Verified BuyerRated 5 out of 5 stars7 months agoLove this wax
This wax was perfect. My daughter and I applied it quickly. It went on great and a little goes a long way! I ordered two jugs because our sauna is 8 by 6 plus 4 by 6 changing room and we only used half of one.
