Danner 950 & 1200 Water Pumps
Couldn't load pickup availability
Danner Pumps are the best I've found for use in a DIY Cold Plunge. I've tested several different styles, sizes and brands - these have held up with a track record in the thousands. Whether you are building a stock tank cold plunge, luxury DIY cold plunge or converting a bathtub into a cold plunge, these Danner pumps will serve you well.
Unlike other cold plunge sites, I stock and ship these out myself. They are the only pumps I use and personally recommend.
What size pump should I get?
- Danner 950 - I've found the 950 is best for 1/4HP chillers. I've paired this with the Active Aqua 1/4HP Chiller and the EcoPlus 1/4HP chiller with great success.
- Danner 1200 - This is by far the most popular pump and works best with 1/2HP Chillers. I've paired this pump with the Active Aqua 1/2HP and Penguin 1/2HP HE.
How does the pump work?
- These pumps are gravity fed. THEY WILL NOT CREATE THEIR OWN SUCTION. This means that water will need to flow freely to it to work. To put it simply, these pumps PUSH water, they don't PULL water.
- The best part about Danner Pumps for a DIY Cold Plunge is that they work in all applications. Stock Tank plunges, Luxury DIY Cold Plunges, Bathtub Cold Plunges and even DIY Chest Freezer Cold Plunges. They work as submersible pumps and in-line so they are extremely adaptable and versatile.
What size fittings do I need?
- Both the Danner 950 and Danner 1200 use 3/4" threaded fittings.
- You will need a MALE threaded fitting for the inlet side of the pump and a FEMALE threaded fitting for the outlet side of the pump.
How should I run the pump?
- These pumps are plug and play. Simple, reliable and consistent.
- There is no programming/variable speed to deal with. Just plug it in and it will run.
- Make sure you do not run these pumps dry, it will damage the pump.
- If you hear clicking when the pump is plugged in, unplug the pump, ensure water is freely flowing to and through the pump and try again.

After experiencing absolutely horrendous customer service from The Plunge (@Plunge), I made the decision to take matters into my own hands and repair and replace the components on my cold plunge myself. My experience with The Plunge was so disappointing that I vowed never to purchase another product from them again!
That's when I found DIY Cold Plunge, and I couldn't be happier with my decision!
Joe at DIY Cold Plunge is the definition of exceptional customer service! From the very beginning, he was incredibly responsive, knowledgeable, and genuinely interested in helping me get my cold plunge back up and running. He took the time to understand my specific setup, helped me identify exactly which replacement parts I needed, and recommended the right pump for my system.
What impressed me even more was the attention to detail. I asked Joe if he could have the parts delivered to my house on a specific day, and he made absolutely sure they arrived exactly when I needed them. That's the kind of customer service you rarely see anymore!
The quality of the parts, the detailed tutorials, the helpful information, and the overall experience with DIY Cold Plunge have been nothing short of TOP NOTCH!
The difference between my experiences with The Plunge and DIY Cold Plunge couldn't be more night and day. One company left me frustrated enough to swear off its products entirely, while the other went above and beyond to earn my trust and business.
If you own a cold plunge and need replacement parts, upgrades, or expert guidance, I cannot recommend DIY Cold Plunge and Joe enough!
Thank you, Joe, for proving that outstanding customer service still exists. You've earned a customer for life!
The parts ordered arrived as expected and on time. Very good communication and service.
Works well
Much stronger than I antipicated...in a good way. Huge upgrade over the little pump that came with my chiller combo.
I got the plumbing package from DIY Cold Plunge and it has been fantastic. I got everything plumbed up, no problems, and Joe was really helpful in answering questions along the way. I got it done in the space I wanted it to be in, and I'm sure I saved a ton of money along the way. Thanks, Joe!

I have a gen 1 Cold Plunge and have been through 3 pumps under warranty and was looking at a 4th. Plunge has different priorities these days besides warranty service on old sales, and so I went to Joe and easily retrofitted to a Danner 950 instead of messing with the DC options. I purchased the pump and the fittings for the chiller and the Danner - all easily available on the site. All I did was install the fittings, cut and glued into the original plumbing to make the Danner compatible, filled the tub, plugged the Danner into a GFCI outlet and I’m good to go
Received the 950 and it pushes water well. It is a little noisy though and makes a plastic. grinding sound, so we will see how long it lasts.
Thank you for the review Dan! These pumps aren't noiseless, but they do rattle a bit when flow is restricted one way or the other. That's the main reason I don't recommend the strainer pre-filters like you have configured here. The outlet strainer should be enough to protect the pump/other components, these pre-filters tend to cause issues
Received today and installed following the videos from your YouTubes and voila!!! Works great and very happy. Also build the filtration kit with Ozone and that also works great!
Bought the 950 pump and chiller pvc fittings. Both work great and couldn't be happier with my cold plunge
Runs quiet and does a great job at circulating water in my 80 gallon ice barrel plunge. Appreciate the support from Joe on number of my questions related to my setup.
I upgraded my filtration system from the podcompany’s standard chiller filter and pump to what Joe recommends and it works amazingly. I wanted to add an ozone generator and quickly discovered that I just needed to upgrade the whole system. I reached out and corresponded with Joe. I was shocked that he would take the time to give me some recommendations and answer questions. Amazing customer service!
These feel like they are very heavy duty, but they are a lot more fragile than I thought. One of the connectors broke off in the PVc from tipping over.
Great service from Joe on questions about the build!
I took Joe’s recommendation and went with the Danner 950. Added to my grizzly 450 cooler along with a whole house water filter and Ventura ozone. Plenty of pressure and water flow. Great recommendation Joe. Thanks for all the support.

Perfect fit for the plunge tub. As a tradesman i was skeptical but it worked great
Works great! Goes well with 1/2 chiller.
Works great for my cold plunge. I have it connected to my ice barrel 400 and works!
Joe has been very helpful. The pumpnis working great.
Joe is awesome
Great product, quick shipping and appreciate the personal touch with the product we received. Thanks
great product, and quick shipping. Would recommend.
Very pleased with my parts and service!
Perfect!
So far, a great pump for my cold plunge, MUCH better than what I got on Amazon. Seriously, don't waste your time there. Also, I had an issue with the setup: I emailed Joe, sent him some pictures per his request, and because he takes customer service so seriously, my cold plunge was correctly running with this new Danner pump within a few hours. I can't get that on Amazon. I'm a new fan of Joe's DIY Cold Plunge, and he's earned my future business.
I just installed & running it. ...SORRY TO SAY ITS LOUD & CIRCULATION IS WEAK, DOESN'T PUMP WATER VERY WELL. WOULD LIKE O RETURN.
Appreciate you taking the time to leave a review here Colin - I did just respond to your email. Noise & weak flow are due incorrect configuration or a priming issue. Send me some photos of how you've got it set up & we can troubleshoot. If your pump happens to be defective I'll get a replacement sent your way
No issues pushing water through Joe’s recommended whole house filter and ozone sanitation configuration.
