Very happy with this build so far. Joe really put together a great set of plans and instructional videos to make the build so smooth.
Went with the 150 Gallon plunge. I had no experience building anything before and I got through it. Joe was really helpful when I made a mistake or couldn’t figure something out he was there to troubleshoot. Not saying this was easy but it was worth it. I love this thing. Friends and fam can’t believe I put this together.
Joe obviously put in a lot of effort to create these plans. The level of detail is very helpful. He responds quickly to questions and his replies show that he has a lot of experience doing this. The project took me way longer than expected. Building something with so few right angles is time consuming (reminded me of building out my van), but I am very happy with the final product and the plans. This thing is very well insulated and all the parts I purchased from DIY Cold Plunge are functioning well. I installed the inline heater to continue plunging through the winter. I also modified a deck box with vents to protect the chiller. If I were to start over, I think I'd go with Joe's stock tank framing plans to reduce the number of cuts, work with square corners, and protect the chiller/heater since I have the room.
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.
Step by step guide worked great to get the cold plunge built. It took a bit longer than I had expected but it was well worth the effort to build it yourself!
With 3 cats that love to sharpen their claws on anything with a little bit of give, I couldn't do the standard blow-up cold plunge. The other pre-fab options were too expensive, so I went on a search for DIY. As soon as I saw this thing, I knew it was what I had to build. I do a lot of woodwork, so I could have built this without the plans, but life is busy, and I knew it would save more money in time than the plans cost... and boy, were the plans ever worth it. The plans and videos saved countless hours of trial and error, and at least a few dollars only having to do the build once. It turned out so well that most people can't believe I didn't buy it pre-made. It's so well insulated that my chiller hardly ever runs. Do yourself a favor, though, and have an extra set of the mixing foam ready. One set only filled mine a little over half way. I built a platform with a lot of casters so I can move it around to get to the filter components and keep the whole thing off the ground that can get quite wet sometimes where I have it located. I also enclosed both sides of the mechanical section because I thought having the filter showing looked kind of ugly. Overall, though, fantastic plans that will easily save you more in time and extra parts than they cost.
I Received a $5k bid from a local finish carpenter to build a CP similar to Joe’s. I bought the complete build/plumbing plans and plumbing kit instead. You don’t need to be a professional finish carpenter to build this thing. The step by step plans are very thorough and walk you through the entire process. Joe made himself super available for any questions and could not have been more supportive. End result is a HIGHER quality product than I could have had built for less than half the price. Highly recommend!
I've been thinking about doing this for a while, and finally got the nerve to order the plans and build my own plunge. With some minor adjustments specific to my tank, Joe's plans were on point. During my build a mistakenly broke some parts and could not find exact replacements locally. I reached out to Joe, he was very understanding and helpful in helping me get replacement parts. I truly could not be happier with the result.
This plan for building your own DIY cold plunge is outstanding. It’s incredibly easy to follow, very well laid out, and covers every single detail you need to know. From start to finish, it walks you through the process step by step and even outlines every piece and part required—so there’s no guessing or confusion along the way. The level of detail makes the build stress-free and enjoyable, even if you’ve never attempted something like this before. Highly recommend to anyone looking to create their own cold plunge setup. 5 stars!
By far my most ambitious DIY project, but the plans were easy to follow and it turned out exactly how I had hoped. Joe was also a huge help. Couldn't be happier.
The plans Joe provided were easy to follow and VERY THOROUGH! The videos of each phase of the build make it super simple. I'm extremely pleased with the entire process and the final product is AMAZING! I love having a professional grade cold plunge that I BUILT for half the cost! Totally worth it!
I have a small deck for my cold plunge so I was super excited to find Joe's new design with a minimalist footprint. The plans and videos were very detailed. There were a lot of steps I had never done before, but thanks to the high level of detail, I had complete confidence at every step on what to do. The plans and supplies list saved me so many hours and the finished product looks and works great!
⭐️⭐️⭐️⭐️⭐️Building our own cold plunge was one of the best wellness decisions we have ever made.
Joe’s plan was easy to follow and the end product is better quality than the commercial plunges.
We use it almost daily, first thing in the morning. It’s a great way to feel clear, calm, and recharged. If you’re on the fence about building your own plunge… Do It!
The guide was clear with step-by-step instructions, diagrams, and video tutorials. Way cheaper than retail plunges. The plans were easy to follow, even for a beginner, and the included filter, ozone generator, and LED light made it feel high-end. Highly recommend!
Across the board great guide; I'm relatively handy so I bought the guide to have the cut plans and the assembly videos were a perfect cherry on top. Walked right through the whole process, everything was nicely in order and very easy to follow.
Happy to have my indoors set up ready every day without constant maintenance.
So after 4 years of buying ice I found this site. Joe has done years of research and development that is sooo worth the cost of the plans. I design flight simulators for a living and was impressed with the amount of detail in his instructions… I did modify a few details but overall his plans saved me tons of overspending and trying to pick components… definitely worth it… hope others are brave enough to take this DIY project on… worse cause reach out to a friend that works in wood to help… good luck everyone
