DIY Cold Plunge

Easy to order, shipped on time.
Instructional videos are very helpful.
Thanks Joe

Everything I have no purchased from them has been perfect and has helped me only make my plunge better

Building my own sauna was one of the most fun and satisfying DIY projects I’ve ever done. From start to finish, the experience was not only enjoyable but also deeply educational—and the final result is something I’m incredibly proud of.

The instructions provided were clear, detailed, and thoughtfully laid out. Each step was explained with enough guidance for even a moderately handy person to follow without feeling overwhelmed. It’s clear that a lot of care went into making this build accessible, yet still leaving room for a bit of customization and creativity.

A huge shoutout to Joe, who was extremely responsive throughout the process. Whether I had questions about materials, clarification on a step, or just needed a second opinion, he was quick to reply and always helpful. That kind of support really boosted my confidence during the build and made the entire experience smoother and more enjoyable.

What I didn’t expect going into this was how much it would make me appreciate the design and craftsmanship that go into these kinds of products. When you're building it yourself, you get to see—and understand—every layer, every joint, every material. It gave me a whole new respect for sauna construction and made me feel even more connected to the final product. Plus, it’s really reassuring to know exactly what materials are in your finished sauna—no guesswork, just quality components you chose yourself.

In the end, not only did I end up with a beautiful, functional sauna, but I also gained knowledge, confidence, and a great story. If you're considering it: go for it. It's a genuinely fun project, and the results are well worth the effort.

Worked perfectly along with a danner 950.

I’ll start by saying that this project had its ups and downs. I’m not a very handy person, but I wanted something I could say I built myself and be proud of, while also saving money by not buying a cold tub from an expensive big brand. I felt like this was a great first project to take on and learn something new. To be honest, I ran into a lot of problems along the way, but that’s on me and not Joe. When I got stuck, I reached out to Joe (like all the time) and he was always so kind, respectful, and patient. He answered my problems quickly and offered alternatives if/when I messed something up from his original plans. We both got stuck at one point and learned that a 100 gallon stock tank can warp, so the curved ends of the tank couldn’t actually sit flush on the frame. You may run into the similar issues if you’ve had your tank for over two years as a stand alone that went through the hot and cold seasons like mine (it froze over one year which may have caused the damage). Moving on, I loved how easy the videos and print outs were to follow for the most part, although I’ll say that the timeframes for each section took a bit longer for a novice like myself (I.e. the expanding foam takes way longer to cure and settle before you can move on, like 2 days later it was still expanding). I’m a bit of a perfectionist and had to learn how to let some things go, so I found myself saying “this will have to do” before moving on to the next step lol. Just know that there will be parts that aren’t perfect and that’s okay! Trust the process and plans Joe has laid out and you’ll see the magic start to come together. Overall, I’m thrilled with how the tub turned out, the new tools I got to work with, and the skills that I learned. It’s a process that took a lot longer than I had intended, but that’s okay! Just know going into it that it is a lot of time and patience, but you’ll be rewarded in the end. Enjoying the process is key here. I’m proud of this build and already bought the chiller enclosure plan to tackle next. Thank you for all of your help Joe and if you’re looking for a project that you can be proud of, you’ve come to the right place. So happy to have found this site and for all the hard work Joe put into these plans so that we can benefit from it. If you’ve been plunging and are tired of buying ice, having to worry about cleaning your water, and are looking to take on a project, get these plans and you’ll be a proud owner like myself! Thanks again Joe!

Building this sauna was very straightforward and the instructions are very easy to follow. I just finished the entire box and now about to add on all the finishing touches. Built the XL version and couldn’t be happier with how it turned out! Really excited to spend some time in this thing. Feels like sitting in a time capsule. If you’re on the fence about buying this dont hesitate!

My garage isn’t terribly aesthetic but this cold plunge makes up for it. Joe has put together some incredible stuff here. The plans are easy to follow for someone who has no background in the trades and borrowed all the tools. Outside of the actual plans he has a multitude of videos that were very helpful on his YouTube page. The videos had answers to all my questions as I went through the build. When I ran into problems with the chiller I reached out to Joe, he was responsive, polite, and understanding to get me over the speed bump. Joe has created a very streamlined system to build a functional and beautiful cold plunge. This water stays extremely cold in a non-ventilated Arizona garage. I looked for months at different types of cold plunge options. I’m glad I chose the plans Joe has put together. I have a ton of pride in what I have built. I can see from other reviews that many other people feel the same way. I’m certain others will share in that pride when they get done building their own.

Thank you so much Joe.

All the good stuff for cold plunge! Nicely packaged. Return buyer and always 100% satisfied!

Good quality, fast shipping and good service

Just wanted to thank you for the work you put into the sauna. I have enjoyed building it and it was laid out so nicely. Now enjoying the fruits of mine, mostly yours, lol labour when I get in my daily session.

Joe is really responsive and thorough, always willing to take time to make sure you get the info you need. Great plans easy to follow and budget your build if necessary.

Turned out great. Heats up very fast. I’ve never built anything out of wood before ,did the build with a 5 1/2 inch skill saw which was a little tough getting perfect cuts on the framing. I would recommend doing the framing one side at a time. Did all my cuts at once and had to redo a few pieces. Overall very happy with the way it turned out and have been using it every evening.

Great condition arrived quickly !

Bought the 950 pump and chiller pvc fittings. Both work great and couldn't be happier with my cold plunge
