Cold Plunges: The Complete Guide
A home cold plunge ranges from about $1,200 for an ice-filled barrel to $14,000 for a stainless steel tub with a built-in chiller. The dividing line is the chiller: a powered chiller holds cold water continuously so you never carry ice, while a tub-only plunge is cheaper but means hauling ice every session.
This hub covers the science of cold exposure, the one decision that swings the price, and our ranked, price-tracked tub picks.

Frequently asked questions
Do I need a chiller or is an ice tub enough?
A chiller holds the water cold continuously with no prep and filters it for weeks; an ice tub costs far less and uses no electricity but means carrying ice every session. If you plunge most days, a chiller pays for itself in convenience.
How cold does it need to be?
Most protocols use 39–50°F. Nearly every chiller tub reaches that; a few push to 32°F. Colder is not automatically better, and beginners often start near 50°F and work down.
What does it cost to run?
A chiller tub draws power continuously to hold temperature, typically $10–25 a month, plus filtration cartridges. An ice tub has no power draw but an ongoing ice cost.
