Having a machine that keeps your water cool seems like a simple device you buy anywhere, but a good water chiller can change how good your cold plunges can be, especially if you live in a hot area.

Just like your sauna, a water chiller needs to function properly, and for a long time..

The following water chillers are the best on the market according to me.

1. Spartan 1 HP Chiller (Best Overall)

The first on the list is the Spartan 1 HP Chiller, the best overall pick. It got so high because it checks all relevant boxes such as user-friendly, easy setup, compatibility with all ice baths, and reliability.

Things You Need To Consider Before Buying A Water Chiller

A water chiller is something you will install and keep with you for a long time. Here is a list of important things to consider before making your decisions:

Cooling Capacity

Ensure the chiller can efficiently lower the water temperature to your desired level for optimal cold therapy benefits. Also, consider how much water your ice bath can hold, and how much water you plan on cooling.

Guide: a good ice bath should be between 50-59 F, as mentioned in my guide to ice bath. Your typical ice bath will most likely never surpass 500 gallons, and all chillers on this list can handle these quantities.


If you don’t want to do the plumbing yourself, then go for models with pumps and hoses included.

Size and Portability

Consider the size of the chiller and whether it can be easily moved or stored in your space. Are you looking to install and forget it, or move it around?

Noise Level

Choose a model that operates quietly, especially if you plan to use it in a residential area.

Temperature Control and Features

Check if the chiller offers precise temperature control and additional features like digital displays or remote operation with wifi

Price and Budget

Balance your budget with the features and quality you need in a chiller.

What Tubes and Pumps Should You Use For Your Chiller Unit?

Visual representation of the components of a water chiller.

A water chiller needs a tube or hose to work, two to be precise. One that takes the water from the the tub and runs it through the chiller unit, and another that takes the cold water from the chiller unit back to the tub.

They also need a pump to get the water flowing.

Now, most water chillers have tubes and pumps already included that are compatible with any cold plunge.

Here are chillers with everything included:

  • Spartan 1 HP

  • Redwood Water Chiller

  • Coldture Water Chiller

For the two others intended for DIY cold plunge, you do need to buy the pumps and hoses. If you want to buy the pump, I suggest one with 1100 gph (gallons per hour), which should be sufficient for an ice bath.

For the hoses, you need to check with the outlet and the size of your chiller and then get the appropriate one.

Is It Really Worth It?

You might wonder…at this price point, is it worth it?

A good water chiller will keep your water at the same temperature every day, for a long time., without ice needed, ever! In other words, it’s a one-time purchase. that you set up and forget.

In hot temperatures, your water will always go up, and you will need to buy ice packs, every single time.

I have been there, and I know that going to buy ice and preparing the cold plunge would be a hassle, and on days when I wasn’t feeling it, I would simply not bother with the ice bath…

A water chiller is worth it if you like taking ice baths. Get the right model and you can even get yourself a warm bath as well, practicing cold and hot therapy with one machine.

Final Thoughts

A water chiller is a great machine to step up your wellness level. There is one designed for all types of people, and all types of usage.

Just remember, if you do not wish to do the plumbing yourself, then buy the all-included models.

If anything, all 5 water chillers listed in this article come with a 1-year warranty, thus protecting your investment. Some of these chillers come with free shipping.

So now, you are equipped with the best information to get your brand new chiller, and start killing it in the ice bath world!
