DIY Cold Plunge Water Filter & Sanitation Build Guide

Great kit. Nathan was a big help when I had questions during install. MUCH BETTER upgrade than the cheap OEM plunge pump. This should have been the way they were made from the beginning.

The DIY kit was incredibly easy to use and the install video was so helpful through every step. I fully expected something to leak or to have missed a step along the way but was so pleased when I filled my tub that everything was running smoothly. Nathan helped answer all my questions for my particular setup and couldn’t be happier with the level of customer support from Plunge Crafters.

I’ve only had this plunger water filter for about a week, but so far it’s been working great! The setup took a little time, but once everything was in place, it’s been a breeze to use. I’ll come back later and update my review after I’ve had more time with it, but my first impression is very positive. Also, the customer service has been excellent.. very responsive, helpful, and a pleasure to work with!

Exactly what I needed. I wanted to DIY but also wanted to buy pieces I can trust to not be bad quality since it’s hard to do via Amazon and even Home Depot. My tub is 1/2 inch so I had to get a reducer but seems to be working well. I put all of this into a cheap deck box with the filter hanging on the outside. Power strip inside so it’s basically a box I can move with a single cord for my inflatable tub.

I would give 5 stars, but I was missing part of the order. I sent them an email and they sent the missing parts, I put it on my plunge tub, and everything is great.

I bought this filter sometime ago for my cold plunge and set it up outside. The installation was very easy and painless. I installed this cartridge filter after the the pump so particles won’t go through the water chiller. The value of these filters is very good, I leave the in-water pump on 24/7 and change filter cartridges monthly to keep my cold plunge totally clean and clear.

This kit saved me so much headache and procrastination. Comes with easy to read instructions and has pictures! To top it all off though it comes with immediate support and response from the plunge crafters team.
I ran into a couple of snags with not aligning the bulkheads to the hole properly (rushing) and got immediate help from Nathan. I also bought the light kit and was having an issue getting it to fit and again Nathan was super quick to coach me through it.

Don’t waste time and money trying to find all the right pieces when doing your own DIY build.
I bought a 150 gallon stock tank from tractor supply, an chiller from walmart and this kit and poof, this thing was built in one afternoon … no brainer and it’s a great price! What’s not to like!

I was hesitant to tackle this job. First "plumbing" job in my life. The written instructions were detailed with images to follow step by step.

Start to finish took me about 7 hours alone (inexperienced.) No problems at all with great custom service!

Def. a fun project & learning experience. It's keeping my 150 gallon Rubbermaid tub ice cold!

Super easy to install and very fast shipping!

Plunge Crafters responded to a question I posted on a Cold Plunge DIY FB group about upgrading my cold plunge setup. They recommended a kit that added a full house filter, high flow Danner pump, ozone generator and 3/4" plumbing. Since it wasn't the setup Plunge Crafters was designed for, I needed to modify it to suit my Ice Barrel 500 and 1/2 HP chiller. Each time I reached out to Plunge Crafters for assistance they responded with answers and guidance immediately. I couldn't imagine attempting this on my own. Thank you Plunge Crafters for such an awesome kit, it's working extremely well for me.

The complete DIY cold plunge kit is awesome.

The kit really includes everything you need (except for the screws to mount the filter). Once you get the hang of the PVC primer and glue, the build starts to fly by.

This thing is awesome! So mush better than my old setup

Can’t wait for my insulated filter housing cover.

I bought this venturi with the Plunge Crafter ozone unit and water filter for my cold plunge setup, and it's worked out great. The 3/4" barbed connections made easy to install with 3/4" flexible PVC spa house. I heated up the spa hose in warm water and then slipped it onto venturi. Once it cooled I didnt even need a hose clamp. Overall I have been really pleased with all the parts I picked up to build out my cold plunge water filter assembly..

I was very impressed at the ease of replacing this pump. Had I not found Plunge Crafter's fix for this pump issue, I was about to buy my 3rd replacement pump 🤦‍♂️

The kit comes with everything you need except the pvc cement and a hose cutter and the insulating foam. All of which I'd never used before and found it to be a fun Sunday project.

The accompanying link to the how-to video is very thorough and accurate.

A bonus: this pump is much quieter than the Orig pump too!

Overall pretty easy to use. A little short on the hosing if you’re making something different than the instructional video.

The pump works. I did call a plumber to install it. I think that I could’ve installed it myself, but I am glad that I called a plumber. I am happy with the new pump. The best part about the new pump is that it has standard fittings. The proprietary pump in the original tub did not have standard fittings. I standard fittings I mean the kind that are on regular garden hoses three-quarter inch or 19.2 mm those are standard fittings. This pump has standard fittings. The proprietary pump did not.

Installed the new pump in 35 minutes, the installation video was super helpful

amazing customer service and fast delivery!

Loved the DIY instructions, much better quality than what I could have come up with. Parts were great and work well. I combined with a 1hp chiller, stock tank and insulated cover to make one hell of a cold plunge. It does take some time to get everything right, but very much worthwhile.
