Cold plunge statistics, with sources
Cold plunge statistics with the source beside each one: market size from three research firms, search demand, costs, trial results and what owners report.
The short answer
$350–363M
That is the size of the global cold plunge tub market in 2025, by three research firms that agree to within 4%. They disagree on almost everything after that, including where the market will be in 2034.
Cold plunge statistics you can trace
Cold plunge statistics are quoted everywhere and sourced almost nowhere. A cold plunge, or ice bath, is a few minutes in water at about 50 to 59°F, and the figures written about it cover the market, search demand, costs, equipment, the trials and safety. This page gives each figure with the source it came from and the condition it holds under.
We collected nothing ourselves except the owner-report counts and the arithmetic, which are labelled. Where sources disagree, both figures are shown.
- $350–363M Global market, 2025
- 68,000 US searches a month for “cold plunge”
- $80–$20,000 What a cold plunge costs to buy
- 11 Randomised trials in the widest review
Market size from IMARC Group, Grand View Research and Fortune Business Insights. Searches from Ahrefs, 2026. The price ceiling is Mayo Clinic Health System’s. The review is in PLOS One, 2025.
How big is the cold plunge market?
Between $350 million and $363 million worldwide in 2025. Three market research firms publish a figure for the cold plunge tub market, and for the base year they land close together.
| Figure | IMARC Group | Grand View Research | Fortune Business Insights |
|---|---|---|---|
| Market in 2025 | $350.3M | $354.6M | $363.0M |
| Estimate for 2026 | $363.5M | $381.7M | $392.9M |
| Forecast | $488.5M by 2034 | $659.9M by 2033 | $740.0M by 2034 |
| Growth a year | 3.76% | 8.1% | 8.24% |
| North America’s share, 2025 | 35.6% | 38.8% | 39% |
| Commercial share, 2025 | 61.8% | 81.4% | About 63% |
The forecasts are where they part. IMARC expects the market to grow under 4% a year and reach $488.5 million by 2034. Fortune Business Insights expects more than 8% a year and $740 million by the same date. That is a gap of about $250 million between two forecasts for one year.
They also split on who buys. All three say gyms, spas and other commercial buyers are the larger share, but one puts it at 62% and another at 81%. If you quote a residential share, name the firm.
Europe holds 27 to 28% of the market and Asia Pacific 23 to 24%, by the two firms that give those figures.
How many people search for a cold plunge?
About 68,000 searches a month in the US for “cold plunge”, by Ahrefs’ 2026 estimate. “Ice bath” gets about 21,000. The two names describe one practice, as cold plunge vs ice bath explains, and Americans use the first far more.
| Search term | US searches a month |
|---|---|
| cold plunge | 68,000 |
| cold plunge tub | 27,000 |
| ice bath | 21,000 |
| ice bath tub | 11,000 |
| cold plunge chiller | 1,900 |
| best cold plunge tub | 1,500 |
| ice bath chiller | 1,300 |
| water chiller for ice bath | 1,300 |
- “Cold plunge” is the American term. The US makes up 72% of worldwide searches for “cold plunge tub” and 50% for “ice bath tub”.
- Australia searches differently. 55% of worldwide searches for “portable ice bath” come from Australia and 19% from the US.
- Interest peaked around 2023. Ahrefs’ volume charts for “cold plunge tub” and “ice bath tub” both peak near 2023 and have been flat or lower since.
What a cold plunge costs
From about $80 for a soft tub you fill with ice to $20,000 for a plumbed tank with every option. The top figure is from Mayo Clinic Health System. The rest are from makers’ own sites and our maths, set out in how much a cold plunge costs.
| Figure | Value | Source |
|---|---|---|
| A soft tub for ice | $80–$200 | Makers’ sites, October 2026 |
| A soft tub with a 1/3 HP chiller | $730–$1,100 | Makers’ sites, October 2026 |
| A hard insulated barrel | $1,100–$1,800 | Makers’ sites, October 2026 |
| Ice for one session | 51 lb | Our maths: 100 gallons from 60°F to 50°F |
| That ice at $3 a 10 lb bag | About $15 | Our maths |
| US average price of electricity | 18.31¢ a kWh | US Energy Information Administration, July 2026 |
| A 280 W chiller’s daily use | 1.4–1.8 kWh | Maker’s spec, The Pod Company, in a 77°F room |
| That chiller’s electricity | 26–33¢ a day | Our maths |
The electricity price is the US Energy Information Administration’s residential average. At that price a small chiller costs $94 to $120 a year to run. By our maths, ice for three sessions a week is about 13 sessions and $195 a month.
The equipment in numbers
Most home tubs hold 77 to 126 gallons and weigh 700 to 1,100 lb once filled, by the makers’ figures for the twelve tubs on our page of cold plunge dimensions.
- 8.34 lb Weight of a gallon of water
- ½ lb Ice per 10 gallons, for each degree of cooling
- About 80 gallons The largest tub sellers rate a 1/3 HP chiller for
- 1 year The usual chiller warranty
The first two are our maths, and the ice rule holds for targets between 45 and 55°F. The rating is the sellers’ own. The warranty is seven of the eight chiller makers whose terms we could pin down.
The working for the ice is in how much ice an ice bath needs, and for chillers in what size chiller a cold plunge needs.
How cold, and for how long
Between 50 and 59°F, which is where the medical advice and the trial evidence overlap. On time they differ, and the five-minute limit for home is Cleveland Clinic’s.
| Source | Water temperature | Time in the water |
|---|---|---|
| Cleveland Clinic | 50–59°F for beginners. Never below 40°F | 1–2 minutes to start. 5 minutes at most |
| Mayo Clinic Health System | 50°F or colder | 30 seconds to a minute to start, working up to 5–10 minutes |
| A review of nine trials, 2016 | 52–59°F gave the best results | 11–15 minutes gave the best results |
What the trials found
The widest review pooled 11 randomised trials with 3,177 healthy adults. Most other figures you see trace back to four other studies. Our guide to cold plunge benefits reads each one in full.
| Figure | What it measured | Source |
|---|---|---|
| 11 trials, 3,177 adults | Stress was lower 12 hours after a plunge. Mood did not change | A systematic review in PLOS One, 2025 |
| 29% | Fewer sick days off work after 30 days of cold showers, with as many days ill | A Dutch trial of 3,018 adults, 2016 |
| 250% | The rise in dopamine after a full hour in 57°F water | A study of young men, 2000 |
| 530% | The rise in noradrenaline in the same hour | The same study |
| 17% | Growth in muscle fibre size in the group that skipped cold water. The cold water group showed no significant growth | A 12-week trial in 21 men, 2015 |
The safety figures
The first 10 seconds to a minute are the most dangerous part of a cold plunge, by American Heart Association News. That is when cold shock makes you gasp and drives up your heart rate.
It does not take icy water. The National Weather Service says cold shock “can be just as severe and dangerous from water temperatures of 50-60°F” as from water at 35°F. That is the range every source above recommends.
What owners report
For our reviews we read more than 100 threads on the r/coldplunge forum and ten brands’ Trustpilot pages in October 2026. The counts by brand are on cold plunge brands.
- Chillers draw most of the faults. At least 16 Penguin owners and at least 12 Coldture owners describe one. Nobody in the twenty threads we read on the Ice Barrel 300 reports a barrel that cracked, leaked through the wall or failed.
- Failures cluster after the first year. Four Penguin owners report a chiller that stopped at about 12, 14, 14 and 18 months, on a one-year warranty.
- These are counts, not rates. No maker we read publishes how many units it has sold.
Figures to treat with care
Several figures on statistics pages that ranked for this search on 13 October 2026 name no source for the individual claim. Four of them conflict with a source we could read.
| The claim | What we found |
|---|---|
| “15-minute weekly cold immersion boosts dopamine by 250%” | The 250% comes from one hour in 57°F water, in the 2000 study above. It did not test 15 minutes a week |
| The market was worth $485.2 million in 2022 | Three research firms put it at $350 to $363 million three years later, in 2025 |
| The market will reach $1.2 billion by 2030 | The highest forecast of the three firms is $740 million by 2034 |
| Homes account for 65% of sales | All three firms say commercial buyers are the larger share, at 62% to 81% |
A figure with no source may still be right. It cannot be checked, which is the reason to leave it out of anything you publish.
