DIY Cold Plunge Kits with Chiller ⁽²⁾

A stock tank cold plunge that holds 39°F, in one order. Each bundle pairs a Plunge Crafters DIY kit with an Active Aqua chiller, voted best chiller by the cold plunge community, and the fittings that connect them. Choose the Complete Build Kit (glued PVC, lowest price) or the Quick Connect Kit (no glue, about an hour), then pick 1/4, 1/2 or 1 HP. Bundling saves $39.95 to $125.95 compared with buying the kit and chiller separately. Add a Rubbermaid stock tank and most builds land under $2,000.
