Worked example: running cost
At 450 watts, the Pro Curve uses 0.45 kWh per running hour. Eight running hours a day is 3.6 kWh, about 108 kWh a month. At a rate of 13 cents per kWh that is about $14 a month. Use your own utility rate and expect more run time in hot weather. See our chiller cost guide.

Frequently asked questions
What is the difference between The Cold Life Ultimate Plunge and Ultimate Lite?
The Ultimate Plunge has an insulated aerospace grade aluminum shell, is rated for indoor and outdoor use and fits users up to 6 feet 9 inches. The Ultimate Lite is a lighter 90 gallon tub that fits users up to 6 feet 5 inches. Both use the 3/4 HP, 7,500 BTU per hour Pro Curve chiller on 110V.
What chiller does The Cold Life use?
The Cold Life lists its Pro Curve chiller at 3/4 HP and 7,500 BTU per hour, drawing 450 watts and 4 amps on 110V, with a 10 foot GFCI power cord and a reusable 150 micron filter. It is sold with the plunges and on its own from $3,799 at the maker.
Do The Cold Life plunges need a 240V outlet?
No. The Cold Life lists the Pro Curve chiller on 110V at 4 amps with a GFCI cord. Plug it into a properly grounded outdoor-rated receptacle, ideally on a circuit without other large loads, and avoid extension cords unless the manual allows them.
Where are The Cold Life plunges made?
The Cold Life says its Ultimate Plunge and Ultimate Lite are fabricated in Miami, Florida. We report that as the maker's statement. We do not apply a Made in USA badge without the maker's written proof covering the whole product.
Is The Cold Life Ultimate Party a cold plunge?
It is a larger round tub with the same 7,500 BTU per hour chiller, a footprint of about 40 by 50 inches with the chiller, and an approximate filled weight of 1,000 pounds, at $2,799 at the maker. Check the current product page for exactly what is included at that price.
Can The Cold Life plunges sit on a deck?
The Cold Life lists filled weights around 850 to 1,000 pounds for the Lite and Party. That is lighter than many hard-shell tubs but still a concentrated load. Check your deck framing with a contractor, and see our deck weight guide before you fill it.
