Best cold plunge chiller under $1,500
If you already own a tub of 90 gallons or more, the Plunge Chill 1HP chiller at $1,099 is the one to get: the brand rates it down to 36°F and says it cools up to 110 gallons from 80°F to 40°F in about 8 hours. Its comparison table lists it for up to 200 gallons. If you're starting from nothing, the $569 Plunge Chill tub-and-chiller bundle costs about half as much and gets you to a brand-rated 39°F.

Which one fits
- You have a stock tank, barrel or tub: the 1HP. Plunge Chill says a 1 HP unit is the usual pick for 90 to 150 gallons and rates it at about 5°F per hour.
- Warm climate or outdoors in summer: the 1HP again. The 1/3 HP units are rated 75°F to 50°F in 8 to 10 hours for 66 gallons.
- Small space, first plunge: the $569 bundle. The tub folds and weighs 9 lb empty.
- You like building your own: the Penguin 1/2 HP is a general-purpose chiller, so budget extra for a pump, hoses and a filter.
