Transform a stock tank into the ultimate DIY cold plunge - for less than $2,500 all-in.
This plan has absolutely everything you need to build a cold plunge from a Rubbermaid 100 or 150 gallon stock tank from start to finish. I've taken out all of the guesswork for you, simply follow along with each step to build the cold plunge you see pictured here - there are diagrams, videos and images for each phase of the project.
Both plans include a plumbing assembly to bypass a chiller if you 1) aren't ready to purchase one just yet or 2) need to pull your chiller in the colder months.

Awesome product! Straightforward plans, easy to follow, no BS. Will update when I actually build it.
This plan will save you a lot of stress. Simple, well explained cuts and instructionsto get you throughthe whole build.I'mso stoked to finish up myprojectand soak right away. Joe is amazing! Personalizing my order and even responding to silly questions I had among my way.
I got the stock tank plans as well as the plumbing plans . So helpful It took all the guesswork out of building my first cold plunge. I did modify the plans to fit the stock tank I had available. It turned out great. I also bought the plumbing parts package it was well worth it. It has all the hard to find pieces.
Joe is super responsive to emails and provided support throughout the building process. The accompanying videos make this doable for almost anyone. I had fun, sharpened my practically non-existent skills, and ended up with a nice plunge.

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!!
