DIY Cold Plunge Spotlight: 300 & 100 Gallon Builds by James

Why build a DIY Cold Plunge?

My wife and I were already aware of the benefits of cold plunging and had been taking cold showers for several weeks already. I actually started out with a converted wine barrel from Lowes, but decided to go all in and have the extra space to actually relax while sitting down. I was already aware of your YouTube Channel and website, and I’m pretty handy with tools, so it just made sense. 

My second build was actually for a customer who saw my current build and contracted me to build him an extra-large 300 gallon tank! That was quite the adventure.

How long did it take to build?

My personal tank took me about two to three weeks (I don’t recall exactly). I used the framing plans from your website, but the rest I free-handed. The 300 gallon tank took me 38 days from time of deposit to delivery. I had roughly 12-15 days during that time however when I did not work at all on the build.

Any cost saving tips for others?

My personal tub was mainly built with leftover framing wood. I purchased the siding from Lowes, and already had all of the plumbing, filters and pump from my barrel setup. The paint I had leftover from when we had our house painted. All in all it was built on a budget, so I’d say it was right on target.

The 300 gallon tub I was over budget by a couple of hundred dollars. Mainly because I was estimating how much framing lumber and siding I’d need. I also used 2x6’s instead of 2x4’s for the vertical pieces to add more support.

Did you make any modifications to the plan?

Yes, only on the 300 gallon build. I used 2x6’s for the vertical pieces for added support and added additional support cross pieces to the base for added support of the tub. Finally, I used pressure treated wood for everything, instead of just for the base.

Were there any unexpected difficulties during the build?

Only during my 300 gallon tub build. Once I built the frame and dropped the tub in, I quickly realized I’d misjudged the angled corner supports and top siding piece that I’d cut out. What I ended up doing was cutting out a secondary siding piece to fill in the gaps, and make it look like the tub was sitting on a secondary level.

It looks like you are taking on projects for others, how did you get started with that?

Yes, my first build was the extra-large 300 gallon tank for a client in the local area. He saw my post and contacted me to build him one. He’s a large guy and wanted a large tub to really stretch his legs out. I love building things and working on projects, so I went all in. Eventually, I hope to do this, as well as other woodworking in retirement in 10 years or so….

What is the best part of having a DIY cold plunge?

Just the ability to hop in when I want! Normally, I plunge every other night just before bed. I’ve had better sleep then ever once I started plunging regularly. Plus all of the health benefits that come with it.

Would you recommend the plans to other DIY’ers?

Definitely. Even if you’re handy with tools and building things, it helps to have all the cut numbers, dimensions, etc already laid out for you and saves you time.
