Flexible PVC Spa Hose is the best hose to use for a DIY Cold Plunge. Don't make the mistake of using cheap vinyl tubing that require numerous hard-to-find barbed fittings for each connection. This spa hose allows for maximum customization and flexibility in your cold plunge.
It bonds directly to PVC fittings using PVC Primer & Cement and can also be used with our Venturi Injector.
This flexible PVC has been used and tested in all my DIY Cold Plunge builds and makes life so much easier when connecting all of your components. Less potential for leaks + maximum flexibility = a BIG win for any DIY project.
This PVC Spa Hose is suitable for use with spas, hot tubs, and whirlpools. This hose is flexible and made for use with PVC schedule 40 fittings.

DIY Cold Plunge has been a great source of information and parts for upgrading my cold plunge.
Great quality spa hose. Significantly better quality than what I’ve seen on Amazon. Flexible but still very strong and bonds to PVC fittings as expected.
This flexible hose is the jam. I first went into my DIY Cold Plunge adventure with some knowledge from Joe's videos. HOWEVER, I should have paid more attention and followed more of his advice. I redid my plumbing setup with this flexible hose and it made it so much more efficient and clean looking! I also used the Venturi injector he sells (as opposed to the cheap amazon find). It's a proper setup now. If you're on the fence between rigid PVC (or PEX in my case.....) or this flexible spa hose. Get this and follow his instructions to avoid upsets and headaches!
Good quality, fair pricing, and fast shipping. What more can you ask for?

Joe was amazing to work with very helpful with all of my questions! Added this to my infrared, sauna for the red light benefit and additional heat so happy with how it turned out!
This came out even better than expected. It’s a solid build with simple to follow instructions. Only update would be that the app needed for the heater has changed to “BN-Hub”.
I couldn’t be happier with this DIY sauna purchase. The plans were clear, well-organized, and very easy to follow. The video tutorials were especially helpful and walked through the key steps in a way that made the whole process feel simple and manageable.
The heater kit was high quality and worked perfectly with the build. Everything functioned exactly as described.
Overall, a smooth project with an amazing end result. I’d absolutely recommend this to anyone considering building their own sauna!
Detailed plans. I wish that the directions for building your own light were included and that there was a video for the XL version.
The project took me about 2 weekends to complete between rounding up supplies and assembly. The temps will make it above 200deg if given time 1.5hrs. I’m 5’7” and after a couple of weeks of use believe the larger build would have given me more room to move about once inside. Over satisfied mostly. Maybe move the heat source a tad lower. Could help with warmer temperatures lowering the box on the legs and torso?
Thanks for the detailed plans and prompt answers to any issues I had!!
