For a broader look, check out our complete guide to the Best Ice Baths. But if you’re looking to start with a chiller, welcome to our guide.
We recommend the Active Aqua 1/4 HP Chiller.

This is the number one choice for DIYers and tinkerers. While 1/4 HP might not seem like a lot, we've found that as long as your tub has decent insulation, it is more than enough power to cool your water.
Keep in mind that if you purchase this, you will also need a separate pump and filter.
- Cools down to 39° F
- Competitive Price
- Great Build Quality
- Energy Efficient
- Easy to Use
- Not fully outdoor-rated.
- Requires additional filter.
- Requires a separate pump.
During our testing the Active Aqua 1/4 HP Chiller performed best for the price point.
Perhaps our favorite feature of this chiller is its ease of use. It contains one input and one output for water and an electrical chord. Simply plug it in, and it basically works right out of the box. There is a small interface on the front with a few buttons, but it doesn’t take very long to figure out how to use it and set it to the desired temperature. We love the simplicity of this chiller as it just works.
For bigger budgets, this fully outdoor-rated chiller is an absolute beast. It can cool water to 37° Fahrenheit in a very short amount of time.
In our testing, we found that the EcoPlus is actually quieter than the 1/2 HP Active Aqua
The galvanized steel housing allows this chiller to be fully rated for outdoor use. We’ve found that it works best in the elements, so we leave it outside all year long.
The unit is very easy to operate. We love that it comes with a 30 ft chord. This means that you can tuck your chiller out of the way and still have full access to the controls.
This is the exact same chiller used by The Pod Company and many other brands at a very competitive price point.
- Cools to 39°F
- 1/3 HP
- Great Price
- Requires separate pump and plumbing hoses.
The best thing about this chiller is that it can be used for salt and freshwater. This means that you can use Epsom salts in your ice bath.
Everything You Will Need
Once you choose your chiller, you aren’t quite done. You’ll still need to connect your chiller, which will take a few extra steps.
As we can see from the diagram above, you will need a pump, filter, and hoses.
The Best Pump for a Cold Plunge
We recommend the Danner 1200 Water Pump. In our testing, we found this pump to be a tank. It works outdoors with Epsom salts. It’s a no-frills solution that you simply plug in, and it just works.
Built to run 24/7, this pump is an absolute workhorse that can handle the elements and is built to last.
We recommend the Hygger 1350GPH Quiet Submersible for a cheaper alternative. What sets this apart is that it has a remote with a display, which will give you a little more control over your pressure.
We prefer this external pump for moving water from your cold plunge tub to the chiller. It’s powerful and has a remote that allows you to control the water flow.
The Best Filter for a Cold Plunge
We recommend the GE GXWH20T Whole House Water Filtration System
Reduce Sediment, Rust, & More with this industry-standard filter. It’s easy to set up and comes with a mounting bracket, and a bypass valve comes in clutch!
When using this filter housing, you’ll also need to purchase the filters themselves to actually filter your water. We recommend the 20-micron filters.
These water filters do a great job of keeping your water clean. For the best results, we’ve found it’s best to replace them every 2 – 4 weeks.
GFCI Outlet for Cold Plunge
It’s important to secure your system with proper electrical. A GFCI outlet will prevent electrocution by shutting off power in the event of a ground fault. We recommend AIDA GFCI Adapter.
Turn any outlet into GFCI with this adapter that will protect you and your ice bath.
The Best Ozone for a Cold Plunge
If you’re looking for a natural way to keep your Ice Bath clean, look no further than Ozone Sanitation. When introduced into water, ozone (O₃) breaks down into oxygen (O₂) while oxidizing and eliminating contaminants like bacteria, viruses, and organic debris. This process ensures crystal-clear water without relying on harsh chemicals like chlorine. Ozone is eco-friendly and leaves no harmful residue, making it a perfect choice for maintaining a pristine ice bath while protecting your skin and the environment.
Caution is advised: avoid breathing ozone directly into your lungs, as inhaling it can be harmful to your respiratory system. Always ensure proper ventilation when using ozone systems.
This Mini Ozone Generator is a compact way to keep your tub clean.
Requires a venturi injector and timer.
Remember that you’ll still need a venturi injector and a timer plug if you are going to use this particular ozone unit. If you are not handy, we love this alternative, which will make the whole process much easier!
