1. A pedicure chair assembly with an auto-fill system for repeated spa treatment use sessions, comprising:
a seat having a seating surface;
a basin located, elevation-wise, below the seat, said basin having walls having an exterior surface, an interior surface defining a basin interior, a basin sidewall, and a basin bottom wall having a drain opening;
an electronically controllable valve configured to control flow of water into the basin;
a first level sensor mounted externally of the basin and configured to detect a first water level of the basin when water is filled in to the basin;
a drain actuator mounted externally of the basin and configured to open and close the drain opening from fluid flow;
a drain sensor mounted externally of the basin and below, elevation-wise, the water level sensor, said drain sensor configured to detect whether water is present in the basin interior; and
a controller programmed to receive a first level indication signal from the first level sensor corresponding to the detected first water level and send a first command signal to the electronically controllable valve to open the electronically controllable valve for fluid flow through the electronically controllable valve or to close the electronically controllable valve to block fluid flow through the electronically controllable valve as a function of the first level indication signal;
wherein the controller is programmed to receive a water detection signal from the drain sensor when water is present in the basin interior and is programmed to send a second command signal to the drain actuator to open or close the drain opening.
