Hands-Free Bath Faucet. Three years ago, Delta introduced a line of kitchen faucets with a battery-operated sensor that made it possible to turn on the taps without touching them. Now this option - called Touch2O Technology - is also available for the company's Addison and Lahara lavatory collections. The flow shuts off automatically five seconds after hands move out of the sensing range. Finish options include bronze, chrome, and stainless steel. Prices range from $435 to $520.
