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

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

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!

Chiller with 3/4" Ports
Exactly what I needed

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

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.

Cold plunge tested

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.

Save time and money!

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!

Go for it!

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!

Outstanding Upgrade Kit

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.

Impressive kit! Enjoyed adding this to my cold plunge

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.

Easy to install ozone venturi

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..

Impressed with the ease of the swap

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!

Active Aqua 1/4HP or 1/2HP
Good product

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.

Chiller with 3/4" Ports
Perfect for the DIYer

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.

FREQUENTLY ASKED QUESTIONS

What comes in the Complete DIY Cold Plunge Build Kit, and what do I still need?

In the box: a Danner Aqua Mag 1200 water pump, an Ambohr SPA-124 ozone generator with venturi injector, a clear 10" cold plunge filter housing with two 50 micron filters, and all the 3/4 inch fittings, bulkheads and flexible spa hose to plumb a stock tank. You also get our illustrated build guides. Pick your chiller under Chiller Type: choose Active Aqua 1/4HP or 1/2HP, or Active Aqua 1HP, and the matching Active Aqua connection fittings are added to your kit. Choose Chiller with 3/4" Ports if your chiller already has 3/4 inch ports. You still need three things: the tub (the guides are written around a 100 or 150 gallon Rubbermaid stock tank), a water chiller, and an insulated cover (optional). We sell chillers and insulated covers. You supply basic tools: a drill, a hole saw for the bulkheads, PVC primer and cement, and a few screws to mount the filter housing.

Which cold plunge tubs does this kit fit?

The guide is written for the 100 and 150 gallon Rubbermaid stock tanks, and that is the build we recommend for most people. The kit is not locked to them. If your tub wall can take a 3/4 inch bulkhead and you have a flat spot to mount the filter housing, it will work. Customers have also installed it on inflatable tubs, an Ice Barrel 500 and chest freezer builds. Tubs with 1/2 inch ports need a 1/2 to 3/4 inch reducer. Email us a photo of your tub before you order and we will tell you what, if anything, you need to add.

Will this kit connect to an Active Aqua 1/4 HP, 1/2 HP or 1 HP chiller?

Yes. Pick the Chiller Type that matches your chiller and the Active Aqua connection fittings are included with your kit, so you are not hunting for adapters at the hardware store. Choose Active Aqua 1/4HP or 1/2HP for the 1/4 HP and 1/2 HP chillers. Choose Active Aqua 1HP for the 1 HP chiller, which uses a different fitting size. The fittings adapt the chiller inlet and outlet to 3/4 inch PVC slip connections that tie straight into the kit's plumbing. None of these three chillers has a built-in pump, which is exactly why the Danner 1200 is in this kit. Not sure which HP you need? Each chiller listing has the sizing details, or email us your tub size and location and we will tell you.

I already own a chiller. Will the kit work with it?

Almost always. The kit is built around 3/4 inch plumbing, which is what most cold plunge chillers use, including our Pro Chillers. If your chiller has 3/4 inch ports, choose Chiller with 3/4" Ports. If you own an Active Aqua 1/4 HP, 1/2 HP or 1 HP chiller, choose the matching Active Aqua option and the connection fittings are included. Some other chillers, including certain Penguin models, use 1 inch inlets and outlets, and some smaller units use 1/2 inch. In both cases you need a pair of adapters to step to 3/4 inch. For any other brand, send us the model number and we will point you to the exact adapters before you order.



How long does the build take, and do I need plumbing experience?

No experience needed. The guides use photos for every step. Customers with zero plumbing background report anywhere from an hour to 3 hours for a first build, taking their time. The slow parts are deciding your layout, cutting the bulkhead holes and letting PVC cement cure, not anything technical. If you get stuck, email us mid-build. We would be glad to help you!

Why 3/4 inch plumbing instead of 1/2 inch?

Flow. A 1/2 inch line chokes the Danner 1200 and most chillers, which means slower pull-down and a filter that does less work per hour. 3/4 inch flexible spa hose keeps flow up, resists kinking and matches the ports on most chillers. It is the same size the pre-built cold plunge brands use. We do not sell a 1/2 inch version of this kit for that reason.

Is the Complete DIY Cold Plunge Build Kit HSA/FSA eligible?

Yes! Our partner Truemed handles everything online in a few minutes. See how the program works and check your eligibility on our HSA/FSA page.

What is the warranty?

Everything is covered by our 1 year warranty. The Danner 1200 is covered by Danner Manufacturers 5 year warranty.

How does the ozone generator keep the water clean? Do I still need chemicals?

The Ambohr SPA-124 produces ozone and the venturi injector pulls it into the water stream while the pump runs. Ozone oxidizes bacteria, body oils and organics on contact, then breaks back down into oxygen, so nothing is left behind in the water. It is the same sanitation method used inside many of the pre-built cold plunges that sell for $5,000 and up. Most of our customers run ozone plus the cartridge filter and use no chemicals at all.

How often do I change the filter cartridges and the water?

Rinse the cartridge every week or two and swap it when it stays discolored after rinsing. For one or two daily users, that is roughly every 4 to 8 weeks. The clear housing lets you see it, so you are not guessing. The kit ships with two 50 micron cartridges. With ozone, filtration and a cover on the tub, most customers go 3+ months between full water changes. Without a cover, plan on more often.

Can I run this setup outdoors, and what about winter?

Yes. The pump, filter housing and plumbing are all fine outdoors. Mount the ozone generator somewhere dry and covered, above the water line so water cannot back up into it. Freezing is the only real risk. If you plunge through winter, keep the pump running so water stays moving, and insulate any exposed hose. If you shut down for the season, drain the lines and bring the filter housing and ozone unit inside.

My chiller has a pump. Do I still need the Danner 1200?

Most likely not. The internal pump within your chiller will be a restriction point within the plumbing. Send us an email at info@plungecrafters.com with a photo and your chillers model information. We can help you identify if there will be any issues ahead of time.

How does the 30-day return process work?

If you are not satisfied within 30 days of delivery, contact our support team at info@plungecrafters.com to initiate a return. Return the product unused in its original packaging and we will issue a full refund once the item is received and inspected. Refunds are processed within 5 to 7 business days of receiving the return. Our support team is available seven days a week from 7 AM to 8 PM CST to walk you through the process if needed.
