A hands-free faucet is a great way to improve your kitchen efficiency, conserve water, and prevent the spread of germs. Tearing up that kitchen for a costly renovation? Not so great. For a digital boost that won't break your wallet, consider Toto's Wi-Touch. This wireless remote can be placed anywhere--at foot, knee, or elbow height --within 3 feet of the control box, which you can install yourself in under an hour. It's compatible with virtually all standard manual faucets, both with and without pullout sprays.
