Our largest cold plunge. More room to stretch out.
Meet the Box 19, designed for those who want a more spacious plunge without the clutter of a separate chiller. Its deep, elongated interior gives you room to recline comfortably and enjoy full-body immersion; all in one streamlined design.
Built-in cooling down to 32°F lets you dial in your preferred temperature, from an approachable introduction to a seriously cold plunge. With no external chiller or connecting hoses, your setup stays clean and self-contained.
An American-made, 1,800 GPH pump circulates water through the filtration system, while an integrated ozone generator helps maintain water quality. Together, they support cleaner water and simpler maintenance, making it easier to keep your plunge ready for your routine.
Our patented power-disconnect system cuts power to all electronics whenever the lid opens. Between sessions, the rubber-sealed lid helps limit heat gain and maintain your selected temperature efficiently.
Finished with a distinctive emerald-blue enamel coating, the Box 19 combines a striking appearance with generous space and everyday convenience. It’s the BoxPlunge for anyone who wants more room to settle in, stretch out, and make cold plunging part of daily life.
