A chiller has to match the tub: water volume, insulation, hose connections and climate. We carry the Coldture Water Chiller Pro and the Penguin Chiller and Filter Kit. Check temperature range, heating, and freeze protection. Need the tub as well? See cold plunges.

    Coldture Water Chiller Pro

    $2,999.00

    Keep a compatible plunge at a repeatable temperature without carrying bags of ice. The Coldture Water Chiller Pro heats and cools from 37–104°F, circulates and filters the water, and connects to Wi-Fi. Check the tub, connections, and placement before choosing it.

    Penguin Cold Plunge Chiller and Filter Kit

    $2,099.99

    Stop buying ice. The Penguin pairs a 3/4 HP, 7,500 BTU/h chiller with a built-in pump and filtration for indoor or outdoor plunge setups. It runs on 110 to 120V power, measures 17 x 15 x 13 inches, and can reach the high 30s to low 40s when the tub, weather, and plumbing are in its favor.
