The process was very easy, detail and the YouTube videos help a lot during the build. Just finish the 100 gallon and I’m building the 150 gallon tank real soon. The only problem I had was the foam insulation very messy wear gloves.
If for even a split second you think you might benefit from having pre-made plans for a cold plunge, you need to buy these plans. Joe has thought through everything for you - and he's done this enough times to have tips/tricks that will save time. If you can use a miter saw, drill, circular saw, and a jigsaw - then you have all the skills required to do this. Everything else you'll see how to do in his videos. This project took me about 4.5 days working 6 hours per day.
I ran out of the maritime foam and had to use fence post foam for the final insulation (just for the last 6'' or so. It seemed to work fine. Having a furniture dolly to throw this thing on toward the end was helpful. Make sure you triple check what wood you're getting. Even with Joe's hyperlinked shopping list, I ended up at home depot more times than I planned. Go ahead and just buy Joe's kit with the pump, ozone injector, and LED - it's worth it and you're not going to save that much finding that stuff on your own. I also opted to get his cover because I think it looks better.
I painted mine with outdoor paint and sealed it with poly. Using a rocita 1/3 HP chiller (I live in Colorado).

Let me start off by saying I am by no means a carpenter or a plumber. Thanks to Joe and this well thought out build plan, you will look like a rockstar.
I’ve been an avid plunger over the years. Mainly in winter months as Mother Nature in New England has kept my trough cold. The rest of the year not so much with the hassle of ice and water changes. This plan checked all the boxes for me. I was looking for efficiency, appearance, function, all under 2k. Problem with a 2k budget is something has to give. QUALITY. Building one was going to be the only option.
The satisfaction you get from building it yourself is also a plus. If you’re considering buying this plan or any of Joe’s plans. DO IT! You won’t be disappointed as they are beyond detailed. I also just bought the sauna plans and am very excited to start building tomorrow.
Easy to follow plans
This was a lot of fun and Joe was super helpful. I hit a few bumps along the way and Joe was patient and knowledgeable, even before I bought the plans and was asking about chiller advice.
The plans are super detailed and the linked shopping list is a game changer. Some of the steps (like cutting the rigid insulation) took longer than the plans said, but this was my biggest project yet so I think that's more of a "me" issue.
My cold plunge turned out really well and I have been so proud showing it off to people. I would definitely recommend this to anyone, regardless of skill level. You'll learn a lot and be left with something to be proud of.
