How to Choose The Right Chiller For Your Needs:

Sticky notes Saying yes and no, representing a decision.

When it comes to choosing the right chiller there are several factors to consider. From location, and frequency of use, to how cool you want your water to be. Here are the things to consider:

Where will your ice bath or cold plunge be located?

Where you are planning to set up your ice bath plays a huge role in what chiller you want to opt for. 

Planning an outdoor chiller setup? Then listen up. Most chillers need some extra insulation and shelter if living outside. Why? Well, chillers are air-cooled machines, so the condenser, heat ejector, etc need protection.

Without adequate insulation and a shelter like a dog house or shed, your outdoor chiller is at risk. Exposure to sun, rain, snow, and other elements can damage those key components.

The temperature of where you are keeping the chiller is also something to consider. Depending on the temperature you will need higher or lower cooling rates and will need to monitor and adjust the water temperature accordingly.

What is Your Cold Water Immersion Therapy Ritual?

How often are you cold plunging? How cool do you like the water? Do you like ice in your water while plunging?

These are also things to consider when you are choosing a chiller. The more often and cooler you like your ice baths the more potent and likely expensive of a chiller you will need. If you want ice in your tub you may need to consider a glycol chiller or consider purchasing an ice-making machine to reduce the cost and inconvenience of constantly having to purchase ice.

How Big Is Your Container?

When choosing a chiller, first figure out the size of your tub or container. The volume of water it holds determines the chilling power you need.

Check the specs on any chiller – each model is designed to cool a maximum amount of water to a certain temp. A 150-gallon chiller won’t effectively cool a 300-gallon stock tank, for example.

Make sure to match chilling capability to your container’s capacity. Undersize and your water won’t get cold enough. Oversize and you’re overpaying.

Price vs Effort:

Determine how much you are willing to spend. Time or Money? Do you rather get a less optimized and simple chiller (get your DIY on) or purchase a more premium and optimized chiller (just set up and go.)

What are Water Chillers for Ice Baths and How Can They Benefit You?

A water chiller for ice baths is a device that cools the water to a desired temperature for cold immersion therapy, such as taking an ice bath or cold plunge. 

Chillers eliminate the need to constantly add ice every 20 minutes or deal with water that is too warm. They allow you to dial in your ideal temperature for DIY ice baths, ice barrels, or any cold plunge setup. You can watch some videos explaining how to use them.

With built-in circulation pumps, chillers efficiently regulate temperature. This enhances the experience and therapeutic benefits of ice baths. Investing in a water chiller optimized for cold plunging takes the guesswork out of temperature control.

Pros and Cons of Water Chillers:

Two sticky notes stating pros and cons


  • Maintain consistent water temperature - No more guessing with ice cubes or dealing with water that warms up too quickly. 
  • Customizable temperature settings - Dial in your perfect temp whether you prefer refreshing cool or extremely cold temperatures.
  • Built-in circulation for efficient cooling - Pumps circulate the water to regulate temp evenly throughout the bath.
  • Convenience - Chillers eliminate the need to constantly add ice. Just turn it on and enjoy stable cold temps.
  • Save Money Long Term- Using chillers to create your own DIY cold plunges can significantly reduce costs.



  • Upfront cost - Chillers require an initial investment that ice cubes don't. But they can save money in the long run.
  • Ongoing electricity use - Chillers require power to run, while ice baths can be "free" if using ice (the cost of having to buy the ice is still applicable.)
  • Noise - Some chillers have loud operations, so placement is important.
  • Added complexity - Chillers require some installation and setup compared to just using ice.

Long Story Short:

Bottom line – water chillers are worth investing in if you’re serious about ice baths and starting cold therapy at home.

We’ve talked through the top chillers out there. Now pick the right one for you – think about your budget, how much water you need to chill, and your ideal temp range.

Watch some setup videos to decide what’ll work best in your space. Then install it and start reaping the benefits of perfectly chilled baths. No more fussing with ice or lukewarm water. Let’s get to plunging!

Water Chiller For Ice Baths FAQ:

Will I need Antifreeze for My Water Chiller?

No, not unless your chiller is outside and exposed to freezing temperatures.

Should I Buy From Alibaba or Ebay?

If you are willing to risk it then it is possible to purchase from these sellers. If you know of a trusted manufacturer that is usually a better alternative.

Can I adjust the water temperature with a water chiller?

Yes, most water chillers for ice baths come with temperature control settings. You can easily adjust the water temperature to your preference, whether you prefer a colder or milder cold immersion experience.

How do I clean the water in the chiller?

To keep the water clean in your chiller, it is important to regularly empty and refill it with fresh water. There are usually sanitizing kits included in your cold plunge tubs and chillers.  With some chillers, you don’t have to worry. They already come with Ozone and UV filtration. Hydrogen Peroxide is also great for cleaning these systems.

How much water does a chiller for ice baths typically hold?

The capacity of a chiller for ice baths can vary depending on the model, but they typically hold several gallons of water. It is important to consider the size of your ice bath or cold plunge pool when selecting a water chiller. Anywhere from 50-200 gallons of water.

Yes, you can add ice to the water chiller to further lower the water temperature during your ice bath or cold plunge. This can enhance the cold therapy experience and provide additional benefits. Some just like the feeling of the ice floating around. If that is your case, consider purchasing an ice maker to reduce costs.

Can I use a water chiller for purposes other than ice baths?

Yes, a water chiller can be used for various applications besides ice baths. It can help cool water for drinking or provide cold water for other therapies or recreational activities that require a cooler water temperature.
