Questions We Get a Lot

A chiller kit pairs an external pump and cooling unit with a tub you already own or source separately, giving you flexibility on size and setup. A standalone cold plunge tub comes as a complete system with the chiller, tub, and sanitation features included. If you want a turnkey experience, our complete tubs are the simpler path forward.

Our cold plunge systems are designed to reach water temperatures well below ambient room temperature, with some models capable of chilling water to the low-to-mid 40s Fahrenheit range depending on the unit and environment. Each product listing includes the specific temperature range and horsepower specs so you can choose the system that fits your recovery goals.

Water hygiene is an important part of owning a cold plunge, which is why several of our systems include built-in filtration and ozone sanitation to help maintain clean, clear water over time. For models without built-in sanitation, we recommend using a water treatment kit, and some of our bundles include one. Refer to the individual product page for the specific sanitation features included with each unit.

We offer free shipping on most orders within the Continental U.S., excluding Alaska and Hawaii. Cold plunges are large items and shipping details may vary by product, so we encourage you to review the product page for specifics. If you need to return an item, our 30-Day Return policy applies, and full details are available in our Return Policy.
