Cold Plunge Chillers

What the chiller does here

Every cold plunge water chiller here cools the water to the mid 30s with no ice, and every one heats it too. Check the manual for your tub. The cold plunge chiller and filter work together with the ozone generator to help keep the water clean. You set the temperature through the panel or phone app, and the insulated thermal covers help hold it between soaks. These units plug into a standard household outlet beyond splashing, and you can compare every cold plunge on the store.

Beside the tub or built in

In a kit, the ice bath chiller is a box beside the tub that you connect with the hoses in the box. Choose from the acrylic and stainless steel tubs, including the lie down shapes, or explore the upright barrels and wooden tubs. With the tubs with the unit built in, you fill the tub and plug it in without connecting hoses. The narrower acrylic all in one tub has a touchscreen control.

The Promax chiller upgrade

You choose the Promax chiller upgrade on a kit page. Its enclosed acrylic case has wheels, carry handles and a color display. The chiller unit uses the same phone app over Wi-Fi and keeps the same cooling power.

A chiller for a tub you already own

If you already own the tub with chiller fittings, you connect a chiller of your own. The SaunaLife packages come with a matched chiller and heater, an external filter and an ozone sanitizer. Explore the SaunaLife wooden tubs and packages for the bare tubs with fittings or the packages with a matched chiller and heater. You can also compare the tubs that run cold or warm.

Your questions answered

Can I buy a cold plunge chiller on its own?

Not here. Every chiller comes matched to its tub, beside it or built in. The Promax chiller upgrade is chosen on a kit page. If you already own the tub with chiller fittings, connect your own unit, or call us and we will talk it through.

How cold does a cold plunge chiller get?

The Plunge Supplier units reach about 35 to 38 degrees Fahrenheit, controlled by panel or app. The SaunaLife packages reach about 33 degrees for the one person tub or 37 for the two person tub. Check the manual for your tub. The Plunge Supplier thermal covers help hold the temperature.

What size chiller do I need for a cold plunge?

Every Plunge Supplier tub comes matched with a 1 horsepower unit for its 92 to 158 gallons. The SaunaLife packages also include a matched unit, with the larger one for the two person tub. The Promax chiller upgrade changes the case, wheels and display, not cooling power.

Does a cold plunge chiller also heat?

Yes, the Plunge Supplier units heat to 104 to 108 degrees, and the SaunaLife units to 107 or 108 degrees. Check the manual for your tub. Explore the Hot Tub and Cold Plunge Combos page for the Plunge Supplier tubs. Your cold plunge chiller runs the same tub cold or warm.

Can a cold plunge chiller sit outside in the sun?

The Plunge Supplier tubs belong indoors or sheltered from sun and rain, with thermal covers between soaks. The Promax case rolls under cover. Users report covering a poolside plunge and its chiller with a tarp between uses, and one owner reports a plunge holding up through eight months in direct sun. Check the manual for your tub before placing your cold plunge chiller outside.

Can I use an aquarium chiller for a cold plunge?

You can connect your own unit to the tub with chiller fittings. Users report mixed results with aquarium units outdoors, and owners say they need a pump, filter, shelter from sun and rain and an insulated tub. Here, each unit comes matched to its tub, with filtration and ozone included.
