About TOTO T21S51#CP GC 6 1/8" 0.5 GPM Single Hole Touchless Bathroom Sink Faucet with 0.08 GPC Controller in Polished Chrome

The GC 0.5 GPM Touchless Bathroom Faucet, 10 second on-demand flow is ideal for high-traffic spaces, providing an elegant water conservation solution.

SOFT FLOW technology gives a soft but enriching feel to the water with little to no splashing.

Key Features & Innovations


TOTO knew there had to be a way to power the sensor without electrical connections or batteries, a way that would eliminate waste and greatly reduce maintenance and the cost of operation. The answer lay in the power of the water flowing through the faucet. EcoPower faucets don’t need routine battery replacement because they are powered by the force of running water. The water-powered turbine in the EcoPower faucet creates an electrical current that is stored in rechargeable cells to power the Smart sensor system.



TOTO has always been an industry leader in green technology. TOTO currently offers a number of products that meet the new California Green Buildings Standards Code (known as CalGreen). These include toilets, faucets, showers, flush valves, and urinals all with superior performance.

ADA Compliant

The American Disability Act (ADA) was enacted in 1990 to establish design codes to serve people of all ages and abilities. A core principle behind TOTO Total Design, ADA standards consider the needs of everyone, no matter their needs, without additional adaptation or specialization, optimizing the bathroom experience for all generations in the family home.
