Cold Plunge Cost Calculator
Estimate what it really costs to run a home cold plunge. Enter your chiller's wattage, how long it runs per day, and your electricity rate to see the monthly and yearly electricity cost. All figures are estimates.
Estimate your running cost
Estimate only. Real cost depends on how hard the chiller works to fight ambient heat, water temperature, insulation, and whether you add a filter pump. Hotter rooms and colder target temperatures raise run time.
What a cold plunge costs to run
The main running cost of a home cold plunge is the chiller, which keeps the water at your target temperature. Because the chiller cycles on and off rather than running constantly, most home owners spend roughly $20 to $60 per month on electricity. The calculator above lets you plug in your own numbers, since a small, well-insulated tub in a cool garage costs far less to hold cold than a large tub in a hot room. At the 2025 US average residential rate near 17 cents per kilowatt-hour reported by the US Energy Information Administration, a chiller drawing 800 watts for 8 hours a day costs a little over a dollar per day.
How to lower the cost
Keep an insulated cover on the tub when it is not in use, place the plunge somewhere cool and shaded, and choose a chiller sized to your tub rather than oversized. A tight-fitting lid is the single biggest lever, because most of the chiller's work goes to fighting heat that creeps in from the air. For a full breakdown beyond electricity, including water care and filtration, read our guide on how much it costs to run a cold plunge.
Typical monthly cost by setup
| Setup | Rough monthly electricity |
|---|---|
| Small insulated tub, cool room | $15 to $30 |
| Average tub and climate | $30 to $45 |
| Large tub or hot climate | $45 to $70+ |
Frequently asked questions
How much does it cost to run a cold plunge per month? Most home owners spend about $20 to $60 per month on electricity, depending on chiller size, insulation, and climate.
Does a cold plunge use a lot of electricity? Less than people expect, because the chiller cycles. A well-insulated tub in a cool space can cost under a dollar a day.
What raises the running cost most? Heat creeping into the water. A hot room, no cover, and an oversized tub all make the chiller run longer.
