Best Cold Plunges of 2026
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 bags of ice for every session.
We compared the cold plunges in our catalog on chiller power, how cold the water actually gets, filtration and sanitation, build quality, and total cost across retailers. Below are the picks, a side-by-side table, and the questions buyers ask most.

Frequently asked questions
Do I need a chiller, or is an ice tub enough?
A chiller holds the water cold continuously, so you step in and plunge with no prep; you also get filtration that keeps the water clean for weeks. An ice tub like the Ice Barrel costs far less and uses no electricity, but you carry and add ice for every single session and drain it often. If you plunge most days, a chiller pays for itself in convenience. If you plunge occasionally, an ice tub is the cheaper, simpler start.
How cold does a cold plunge need to be?
Most protocols use water between 39°F and 50°F. Nearly every chiller tub reaches that range; a few, like the Sun Home Pro, push to 32°F for people chasing the most extreme cold. Colder is not automatically better, and beginners often start nearer 50°F and work down. What matters more day to day is that the chiller holds your chosen temperature without you topping up ice.
What does a cold plunge cost to run?
A chiller tub draws power continuously to hold temperature, typically $10 to $25 a month on electricity depending on your climate and how cold you keep it. Filtration cartridges and sanitation (ozone or UV on the better models) are a smaller ongoing cost. An ice tub has no power draw but an ongoing ice cost that adds up if you plunge often.
How much space and what surface do I need?
Plan for a footprint of roughly 3 by 6 feet plus room around it to get in and out, on a surface that can hold 600 to 1,500 pounds of tub plus water. Most chiller tubs run on a standard 120V outlet. Stainless and fiberglass tubs are heavy and effectively permanent once filled, so decide on placement before delivery.
