AS ColdPlunge Ice Bath Water Chiller, 1/3 HP Upgraded Cold Plunge Chiller with External Filter Water Pump, 110V Cooling Chiller
AS ColdPlunge's upgraded 1/3 HP 110V chiller with external filter water pump, built to cool home ice bath tubs.
A chiller is what separates a one-off ice dump from a genuine daily habit. Instead of hauling bags of ice, a chiller cools and holds your plunge water at a set temperature, so the tub is ready whenever you are. Many units also filter and circulate the water, keeping it clean between sessions and cutting down on refills. In this guide we compare chillers on cooling power, temperature range, filtration, noise, and how well they pair with common tub sizes. We also note energy use and ease of maintenance, since a chiller runs far more often than the tub itself. For anyone serious about consistent cold exposure at home, the right chiller turns a chore into a routine you can actually keep.
