Cold plunging is a simple idea with two very different price tags. You can fill a tub, dump in ice and call it an ice bath. Or you can buy a tub with a chiller and filter that holds the water at a set temperature all week. Neither is right for everyone, and the best way to choose is to understand what you're paying for.
Safety first: Cold water immersion can be risky, especially for people with cardiovascular or other health conditions. Check with a doctor, don't plunge alone, avoid alcohol, and ease in gradually. This is general information, not medical advice, and we don't make health claims about cold exposure.
The short answer
- Not sure you'll keep doing it: start with a portable ice-bath tub and bags of ice.
- Want to start cheap but leave room to grow: an Ice Barrel 300 with ice, then add the Ice Barrel Chiller later.
- Know you'll plunge often and want no fuss: a chilled all-in-one such as Plunge.
How we picked
We used the makers' own product pages to compare insulation, chilling and filtration options, size, weight, electrical needs and warranty, and we describe cost in price tiers rather than exact prices because they change often. We did not test these products ourselves. Cold-plunge companies rename and reprice products frequently, so confirm current specs before you buy. See our methodology.
Our top picks
Cheapest way to try an ice bath
Portable inflatable ice bath tub
The cheapest way to find out if cold plunging is for you.
A portable inflatable ice-bath tub plus bags of ice is the lowest-cost way to find out whether you'll stick with cold plunging. It takes a lot of ice to reach cold-plunge temperatures, the water gets dirty, and it's less stable than a barrel or tub.
What we like
- Inexpensive and easy to store
- Add ice and water for sessions as needed
- No installation
Trade-offs
- You'll need a lot of ice to hit true cold-plunge temperatures
- Not as stable or durable as a barrel or tub
- Best for
- Trying cold plunging before investing in a chiller system.
- Skip it if
- You want a stable, durable setup, or you don't want to buy lots of ice.
Best middle path
Ice Barrel 300
A compact insulated barrel that works with or without a chiller.
A fully insulated, American-made barrel (about 35.5 in. wide and 30.5 in. tall, fits people up to about 6 ft) with built-in chiller ports. You can start with ice and add a chiller later. It weighs about 700 lbs when full, so plan a solid, level base.
What we like
- Fully insulated and made in the USA, per the maker
- Built-in chiller ports so you can add a chiller later
- Smaller footprint — about 35.5 in wide × 30.5 in tall
Trade-offs
- Weighs about 700 lbs when filled, so choose a solid base
- Fits people up to about 6 ft tall
- Best for
- Cold-plunge beginners who want a barrel-style plunge they can upgrade later.
- Skip it if
- You're taller than about 6 ft, or you can't provide a solid base for roughly 700 lbs filled.
Best chiller upgrade
Ice Barrel Chiller
A half-horsepower chiller that turns an Ice Barrel into a chilled plunge.
A half-horsepower chiller that the maker says cools to 37°F, with Wi-Fi app control, on a standard ~115V circuit with a 15A fuse rating. It turns an ice bath into a chilled plunge so you stop buying ice. It costs thousands of dollars on top of the tub, needs regular filter care and carries a one-year warranty.
What we like
- Cools down to about 37°F, per the maker, with app control over Wi-Fi
- Runs on a standard ~115V circuit with a 15A fuse rating
- Lets you start with ice and add the chiller later if you stick with it
Trade-offs
- Costs thousands of dollars on top of the tub
- The chiller carries a one-year manufacturer's warranty
- Needs regular filter cleaning and water care
- Best for
- People who already own an Ice Barrel, or any cold-plunge tub with chiller ports, and want to stop buying ice.
- Skip it if
- You haven't tried cold plunging yet, or you only plunge a few times a month.
- Power: ~115V, 60Hz, 15A fuse
- Lowest temperature: 37°F (maker claim)
- Size: 18.63" × 16.40" × 20.40"
- Weight: 65 lbs
Best all-in-one chilled plunge
Plunge (The Plunge, All-In Gen 2, Pod)
The best-known premium cold plunge brand with app-guided chilling.
Plunge's lineup (The Plunge, the All-In Gen 2 and the upright Pod) pairs a tub with a chiller and filtration for plug-and-plunge use. It's a premium purchase, typically thousands of dollars before shipping and setup, and the site lists a one-year warranty.
What we like
- Cold plunge systems with built-in or paired chillers designed for convenience
- The All-In Gen 2 is described as plug-and-plunge with built-in filtration and ozone
- The upright Pod design is built for small spaces
Trade-offs
- A premium price — typically thousands of dollars before shipping and setup
- One-year warranty listed on the site; read the full terms
- Best for
- People who want consistent cold-plunge sessions with the least maintenance.
- Skip it if
- You're still unsure whether you'll use it regularly.

How to choose
How often will you plunge?
Be honest. Plenty of people try cold plunging, enjoy it for a few weeks and move on. If you're not sure, start with ice. If you already plunge several times a week, a chiller starts to make sense.
Ice vs. chiller costs
Ice is cheap per session but adds up, and getting a tub cold enough takes a lot of it. A chiller costs a lot upfront and then uses electricity and filters. Chillers draw power when cooling, so your climate, how warm the yard is and your electricity rates all matter. Ice Barrel's chiller, for example, is rated at about 115V with a 15A fuse.
Space, weight and base
A filled barrel is heavy: Ice Barrel lists about 700 lbs for the 300 when full. Put it on a level, solid base, and plan how to drain it. Check the installation guidance for your climate, especially if the water can freeze.
Water care
Cold water still grows things. Filtration, sanitizer and regular cleaning keep it safe and pleasant; Ice Barrel says to clean or replace chiller filters monthly and use its stabilizer. Follow the maker's instructions, and change the water as directed.
DIY setups
Some people build a plunge from a stock tank or other tub. These work, but anything that mixes water and electricity needs proper GFCI protection and installation, and an improvised setup can be unsafe. Ask a qualified electrician before adding a chiller or pump to a homemade tub.
Safety basics
Keep sessions short and build up gradually. Never plunge alone, avoid alcohol, and have a plan for getting out and warming up. Talk to your doctor first, especially with any heart or blood-pressure issue. If you have a lid, never lock it while someone is in the water.
Hot and cold
Many people pair a plunge with heat. See our guide to infrared vs. traditional saunas and the best backyard saunas, or the full roundup of the best cold plunge tubs.
Frequently asked questions
What's the difference between a cold plunge and an ice bath?
An ice bath is a tub of water that you chill by adding ice for each session. A cold plunge usually means a tub with a chiller (and often filtration) that keeps the water cold, clean and ready to use at any time. The experience is similar; the difference is convenience, cost and water care.
How cold should the water be?
Many people use roughly 40–55°F (4–13°C), and beginners often start warmer and for shorter periods. Everyone's tolerance is different, so build up gradually and get out if you feel unwell.
Is cold water immersion safe?
It isn't risk-free. Cold water can be dangerous for people with heart conditions, high blood pressure and certain other health issues. Talk to your doctor first, never plunge alone or after drinking alcohol, and never lock a lid while someone is in the water. This is general information, not medical advice.
Do I need a chiller, or is ice enough?
Ice is enough to start and to find out if you'll keep it up. If you plunge often, ice gets expensive and tedious, and the water gets dirty, which is why many regular plungers end up buying a chiller. Barrels with chiller ports let you start with ice and add a chiller later.
