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.

  • Complete shopping list with direct links
  • PVC parts breakdown & best practices
  • All-in cost for plumbing parts only ~$250
    • Estimate does not include tank, pump, or ozone generator

  • Complete shopping list with direct links

Must buy

Best decision I made! I thought I wouldn't need it , but having this plan really helped me. Without it i'm sure I made a mistake that took me a while to get back.

Joe makes instruction Short.
But very clear and concise. Very easy to follow and great quality! It was 3 x more helpful and great quality then I had thought at the time of purchase!

Outstanding plans!

These plans are so thorough. The plans don't just list what you need, but exactly what you need, with pictures. There are videos to accompany the instructions to walk you through each of the phases of the build, as well as exact plans for the cuts you'll need for the wood. Outstanding job!

DIY Plans were amazing!

I used the 150 gallon tank. The plans were simple to understand and easy to execute. This was the best build ever! Someone needs to tell IKEA to take notes. Highly recommend. This took all the guess work out. I watched the videos and then went to cutting and building. Took about 4-5 hours with some breaks. Great job, Joe!!!

Well worth the money, to say the least!

These plans are meticulous and very easy to follow. Even if you are very handy, it is well worth the investment to see all of the notes incorporating Joe's vast experience and use the shopping lists (with links) to help you make sure you have everything. I made a few tweaks (especially to the frame), but I can't even quantify the amount of hours and headache that these plans saved me.
