Toto St405m01 Toilet Tank Cover 1/1.6 Gpf Cotton White

Product Description

The TOTO st405m#01 is a vitreous china toilet tank and cover designed for wall-mount installations with a dual-flush push button system. It supports two flush volumes: 1.0 gallon per flush for liquid waste and 1.6 gallons per flush for solid waste, helping meet low-consumption plumbing requirements. The tank fits a 12-inch rough-in and uses a 2-inch flush valve. Finished in Cotton White, this unit is intended for licensed plumbers working on residential or light commercial bathroom fixture installations where a clean, flush-button aesthetic is specified.

The st405m#01 tank and cover is suited for wall-mount toilet configurations using a 12-inch rough-in dimension. At 18.75 inches wide and 7 inches deep, it is sized for standard residential and compatible commercial applications. The push button flush actuator is integrated into the tank design, making it appropriate for installations where lever handles are not desired or specified. This unit is imported and sold as a tank-and-cover assembly.
