Cold Plunge Tubs and Chillers Built for Daily Use

Skip the ice runs. A cold plunge chiller circulates and filters your tub water while holding it at a set temperature—typically 39–50°F—around the clock. Blue Sky Yard carries Penguin Chillers' water and glycol chillers from 1/3 HP to 2.5 HP, complete chiller-and-tub packages, and a barrel chiller sized for the Ice Barrel 400, so you can plunge every morning at the same temperature.

Sizing a cold plunge chiller

  • 1/3–1/2 HP – Bathtubs and stock tanks up to ~100 gallons in a garage or shaded spot.
  • 3/4–1 HP – 100–150 gallon tubs, outdoor use in warm climates, or faster pull-down.
  • 1.5 HP and up – Large tubs, commercial gyms and multiple users per day.

Titanium heat exchangers resist corrosion from salt and sanitizer, and built-in filtration and ozone options keep water clear for weeks between changes. See How to Set Up a Cold Plunge at Home for tub options, plumbing and electrical requirements.
