Launching soon

Auto dose your hot tub. No more weekly dosing!

Hotubby hangs over the wall of the hot tub you already own. It reads pH, sanitizer and water temperature, and adds chlorine, pH up, pH down and alkalinity in small, capped doses while the pump runs.

We only use your email to tell you about the Hotubby launch. Privacy.
