Cold plunging has gone from athlete recovery trick to backyard staple. The good news is that you don't need to spend thousands to try it. The bad news is that the cheap way gets old quickly, and the expensive way is a real investment. Here's how the options compare.
Safety first: Cold water immersion can be risky, particularly 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.

How we picked
We compared manufacturers' own product pages for insulation, chilling and filtration options, size and weight, warranty and price positioning, and we weighed what each option is realistically good for. Cold-plunge companies change names, products and prices frequently — for example, the brand formerly known as Cold Plunge now redirects to Plunge — so check current specs and pricing. See our methodology.
Our top picks
Best premium all-in-one
Plunge (The Plunge, All-In Gen 2, Pod)
The best-known premium cold plunge brand with app-guided chilling.
Plunge now sells the products formerly branded Cold Plunge as well; its lineup includes The Plunge (paired with a Pro Chiller), the All-In Gen 2 with a built-in chiller and ozone filtration, and an upright Pod for small spaces. They're plug-and-plunge designs with app control, and they cost thousands of dollars. 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.
Best barrel for most people
Ice Barrel 300
A compact insulated barrel that works with or without a chiller.
A fully insulated, American-made barrel with built-in chiller ports so you can add a chiller later. It's about 35.5 inches wide and 30.5 inches tall, fits people up to about 6 ft, and weighs around 700 lbs when full — make sure your base can handle it.
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 for taller people
Ice Barrel 500
A larger plunge with built-in stairs and a seat.
A larger barrel with built-in stairs and an interior seat, fitting people up to about 6 ft 9 in, available with a chiller bundle. It's about 900 lbs when filled, so plan a sturdy, level base.
What we like
- Fits people up to about 6 ft 9 in, with built-in stairs and an interior seat
- Fully insulated with chiller ports
- Chiller bundle available for consistent temperatures
Trade-offs
- About 900 lbs filled — needs a level, strong base
- Large footprint and a premium price
- Best for
- Taller users and households that want a long-term plunge setup.
- Skip it if
- You don't have a level, strong base for about 900 lbs filled, or you want a small footprint.
Best way to try it cheaply
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 cold plunging is for you. It takes a lot of ice to reach cold-plunge temperatures, and it's less stable than a barrel.
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.
How to choose
Chilled vs. ice
- Ice only: cheap to start, but you'll buy a lot of ice and the water gets dirty.
- Chiller: keeps water cold and clean, uses electricity and costs more upfront.
- Barrel with chiller ports: a good middle path — start with ice, add a chiller later.
Indoors or outdoors?
Outdoor installs need a level, strong base (a filled plunge can weigh several hundred pounds or more) and a power source with proper GFCI protection if there's a chiller. Check the manufacturer's installation guidance for your climate.
Size and fit
Check interior dimensions against your height and the room you have around it. Taller users should look at the larger barrels.
Water care
Cold water still grows things. Filtration and ozone, a cover, regular cleaning and sanitizer all help. Follow the manufacturer's instructions.
Running costs
Chillers draw power continuously when cooling. Costs depend on your climate, usage and electricity rates.
Hot and cold
Many people pair cold plunges with a sauna or hot tub. See our guides to backyard saunas and inflatable hot tubs.
Frequently asked questions
How cold should a cold plunge be?
Many people use roughly 40–55°F (4–13°C). Beginners often start warmer and for shorter periods. Everyone's tolerance differs, so build up gradually.
How long should I stay in?
Short sessions — often one to five minutes — are typical. There's no need to push it; listen to your body and get out if you feel unwell.
Is cold plunging safe?
Cold water immersion isn't risk-free. It 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 the lid while someone is in the water.
Do I need a chiller?
Not necessarily. You can use ice, but it's costly and time-consuming. A chiller keeps water cold and filtered, which makes regular use much easier — and is why most people who plunge frequently end up with one.
