G4 is a new type of wall-mounted flush-type siphonic toilet. Unlike traditional wall-mounted toilets, this product has a tankless design, using solenoid valve accessories to separate water lines to provide direct flushing. The built-in wall mount support allows for flexible installation locations. The side buttons perform commonly used flushing and cleaning functions. Designed by Qini Liang, Tao Zhang, and Xiaoshan Yang.
