Cold Plunges

A cold plunge is an insulated tub with a chiller that holds water at a set temperature. Models differ in how cold they go, how much water they hold, and whether you sit upright or lie back. Chiller power decides how fast the water recovers between sessions.

We look at the temperature range, the chiller’s horsepower, and how the water is filtered. Warranty terms matter too, since the vessel and the chiller are usually covered for different lengths of time. So does the electrical requirement, because a plunge that needs its own circuit is a different purchase from one that plugs into a wall.
