ThermoX Drop

Most cold plunges ask you to buy a whole new tub. Drop does not. It is a self-contained chiller that cools the water in the bath you already own, so you can plunge at home without rebuilding your bathroom around it.

A 3.5kW cooling system holds a steady, controlled cold once you reach your set temperature, anywhere between 37 and 77°F. Ozone sanitation and 20 micron filtration keep the water clear between sessions. When you are done, the whole unit rolls away on four locking casters.

Fill the bath, clip on the hose-arm, drop the intake in, set your temperature. That is the whole setup.

Every ThermoX Drop includes:

• Drop chiller unit
• Arched intake hose-arm with submersible intake head
• Four locking casters (fitted)
• Replaceable 20 micron filter
• Power cord
• Suction cups
• Wi-Fi app pairing guide
• 1-year warranty

Bath not included. Drop is designed to work with a standard home bathtub.

Drop is designed for true plug-and-plunge simplicity. Fill your bath with cold water, clip on the hose-arm and drop the intake in fully submerged, then set your temperature on the panel or the app. The chiller circulates, cools and holds.

Ozone sanitation and a 20 micron filter keep the water clear between sessions, so you are not draining and refilling every time. Replace the filter roughly monthly for best performance. Position the unit with good airflow around it and avoid direct sunlight for efficient heat exchange. Empty the water if the ambient temperature drops below 36°F to prevent freezing.

ThermoX Drop runs on a standard US 110–120V / 60Hz outlet, drawing up to 12A. Connect through the supplied leakage-protection plug into a properly grounded outlet and switch on. No special wiring or installation is required.
