A cold plunge barrel is an upright tub you sit in. The insulated Ice Barrel 300 and 500 compared, with what owners report and how they differ from a pod.

All our tub picksThe short answer
A cold plunge barrel is a rigid, upright tub you sit in with the water at your neck. The best is the Ice Barrel 500 for people up to about 6 ft 3 in, and the Ice Barrel 300 for anyone 6 ft or under. Both are insulated, take a chiller, and hold cold far longer than a soft pod.

All our tub picksWhat a cold plunge barrel is
A barrel cold plunge is a moulded plastic tub, taller than it is wide, that you climb into and sit upright in. The good ones are insulated, which is the whole point of paying for one. Shops also call soft round pods “barrels”. Those are portable pods, and we cover them in portable ice baths. If you are still choosing a type, start with our pick of the best cold plunge tubs.
We have not used these barrels ourselves. The specs are the maker’s, from its own site, and the owner reports come from r/coldplunge and one long-term reviewer.

Which cold plunge barrel is best
Ice Barrel 500
The one to buy if you are over 6 ft and plan to plunge for years. Owners on r/coldplunge report snow lasting six days in it, a year and a half of use with no quality problems, and water that stays cold through an Alabama summer.
The built-in bench is its flaw. A 6 ft 3 in owner sits with his shoulders two to three inches out of the water, and the company’s advice to tall owners is to sit opposite the seat.
Ice Barrel 300
The better buy for anyone 6 ft or under. It has the same insulation and chiller ports in a smaller footprint, and costs $600 less on the maker’s site. A 6 ft owner says he sits comfortably with the water at his jawline.
The older Ice Barrel 400
If you see a 400 second-hand, know that it is a different tub. A long-term reviewer who owned one reports about 3.5 hours of cold in 75°F weather and 100 to 140 lb of ice at a time, and it had no chiller ports. The 300 and 500 are insulated and have them.
Who makes Ice Barrel now
Since May 2025 the Ice Barrel brand has belonged to the sauna maker Sunlighten. Its press release of 20 May 2025 says it bought the key assets of Ice Barrel Inc. and runs them as Ice Barrel, LLC, a wholly owned subsidiary. The release says nothing about warranties or support for barrels sold before that date.
For a new barrel this changes little: the limited lifetime warranty is stated on the maker’s site today. If you are buying second-hand, or you own a barrel bought before May 2025, ask the company in writing whether its warranty still applies.
How much ice an Ice Barrel needs
From 60°F tap water to 50°F, the Ice Barrel 500 needs about 48 lb of ice and the 300 about 39 lb, by our maths. From 70°F, that rises to 97 lb and 79 lb. The full table is in how much ice an ice bath needs.
Insulation means the ice lasts. That is the difference an owner pays for.
Should you add the Ice Barrel chiller?
No. The barrels have strong owner reports and the Ice Barrel chiller does not. In one r/coldplunge thread, at least ten owners describe pump errors within days, leaks and slow support. The detail is in our Ice Barrel chiller review.
Owners pair the barrels with other chillers instead. Check the warranty wording first: retailers describe the barrel’s warranty as excluding damage from chillers the maker has not approved.
Cold plunge vs Ice Barrel
People ask this when choosing between a barrel and a lay-down cold plunge with a chiller built in.
Choose a barrel if
You like sitting upright, you are short of floor space, and you want a tub with no electronics to fail. You can add a chiller later.
Choose a lay-down cold plunge if
You want to stretch out and get your head under, or you want the chiller, filter and tub from one maker with nothing to plumb.
A barrel is simpler and smaller. A built-in system is more convenient and costs several times as much. The price tiers are in what a cold plunge costs.
Barrel against the other types
A barrel costs ten times or more what a soft pod does, and holds cold many times longer. If you are still finding out whether you like cold plunging, start with a pod. The types are compared on the tubs page, and all our picks are in the best cold plunge tubs.
Common questions
Which cold plunge barrel is best?
The Ice Barrel 500 if you are over 6 ft, and the Ice Barrel 300 if you are 6 ft or under. Both are insulated and take a chiller.
How tall can you be for an Ice Barrel?
The maker says 6 ft for the 300 and 6 ft 9 in for the 500. Owners say the 500’s bench makes it tight above about 6 ft 3 in, and a 6 ft 8 in owner says it would not work for him.
Is a barrel tub hard to get in and out of?
Harder than a lay-down tub. The 500 is 42 in high and comes with a step. A long-term reviewer of the older 400 says it is difficult for anyone not in good shape.
Does an Ice Barrel need a chiller?
No. Owners use them on ice for a year and more. A chiller makes sense once you plunge often enough that the ice costs more than the electricity.
