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.

Great ozone generator. Easy setup and works perfectly with a venturi. I struggled with keeping my plunge sanitized for months and this fixed all of that immediately. Highly recommended.

I purchased the sauna plan after building a cold plunge last year. Both plans are very detailed, easy to follow, and include videos. So now I have both a sauna and a plunge for less than what others are selling one for. I have a great shop, but even without one this build can be easily
done with rudimentary tools and woodworking skills. The build is complete, waiting on the preorder heaters to ship.
I’m a hobbyist woodworker. Overall, I’m very happy with this build! I think it’s my most complex woodworking project to date. The materials list was great, the diagrams were clear, and the videos very helpful. Joe was quickly responsive when I emailed him with questions. I had a good time making this, and I’m impressed with the end-product. I’m proud that I built this, and I’m so excited for daily sauna sessions!
A couple things I would do different if I made this again: I would not use dimensional 2x4 and 2x6 fir lumber as it was thicker than the other framing wood that I bought, or I would plane it down to be the same thickness as the other wood. This caused my framing to bulge wherever it was used, and I didn’t realize it would be an issue until it was too late. This made fitting the siding to each panel difficult, and I wound up with some gaps and overhangs in some areas. I installed some trim to go along each edge to hide the imperfections at the seams. The jet black Varithane stain that Joe used wasn’t taking to my siding, so I had to buy black exterior paint instead.
Finding some of the materials was also a little difficult. Nobody had 5/4” cedar planks, and I drove all over to find decent 1x6 clear cedar, and it was pretty expensive at a specialty wood store. Finding the R15 value Rockwool at my Home Depot was pure luck… they don’t carry that anymore, but someone had recently returned one package, and there it was waiting for me.
I don’t think the materials list calls out a 1 ½” hole saw, so I had to go out and buy that right before I needed it. Not everyone has a nail gun, but luckily my friend let me borrow his.
My receipts came out to $1826.86, which is 50% more than the ~ $1200 stated, but I noticed items like the bulbs, cedar TNG, backrest, grommet cover, sauna oil, paint, and some misc supplies and tools were left out of his calculation. Plus things cost more in California. This still costs 1/3 of similar-style commercial infrared saunas. I would definitely recommend this project for someone who is good with tools and building stuff.
My friends are all asking me about my new sauna! It’s attention-getting for sure.
