. They've been in restrooms in airports, hotels, and other public places for years. Now hands-free electronic faucets are making their way into the home, but oh so slowly. Hands-free faucets, which typically run on battery power, began showing up in personal bathrooms a couple of years ago for a number of reasons. The faucets offer sanitary touch-free operation while conserving water and energy (they only dispense water when the sensor picks up hand motions). They also regulate flow time and prevent overflow and most have indicators that warn the homeowner when the battery is about to expire. Electronic faucets require little effort to use, which makes them great for both public and private bathrooms, says Wayne Ash, a professional training coordinator for the National Kitchen & Bath Association (NKBA). That's why they appeal to all age groups, although they're particularly useful in children's bathrooms and senior suites. Hands-free faucets install easily in new and retrofit applications, are available at numerous price points (from $400 to more than $800), and can increase your profits because they're higher-end models. However, one quirk associated with hands-free faucets can be aggravating to some homeowners. "They're great for kids because the water comes out pre-mixed, which prevents scalding, but that can be a con if you want to get a cold drink of water," says Paul Greenspan, owner and president of Milwaukee-based Milwaukee Kitchens and Baths, which designs and installs kitchens and bathrooms. Some companies, like Taiko USA and Delta, have taken note of that complaint and are developing hands-free models with manual temperature adjustments. "The difference between commercial and residential is that people want different temperatures at home," says Taiko USA representative Leo Maercovich. Likewise, some homeowners are concerned that hands-free faucets might fail, leaving them no way to turn on the water. But pros say the only time the units fail is when the house loses power. "If you have no power, nothing in the house works," says Lisa M. Robey of Harvey's Kitchens and Baths, a Sterling, Va.-based dealer/installer. Form Versus Function Although hands-free technology is improving, the faucets still have a long way to go when it comes to aesthetics. The lack of stylish options prevents many builders and homeowners from choosing electronic faucets. A recent NKBA trends survey shows that electronic faucets only are installed in 3 percent of new construction and remodeling projects. "They don't have much style," Greenspan says. "They won't be more popular in residential settings until designs improve, but they're evolving." Other bath designers predict hands-free faucets will become more popular once homeowners and pros take notice of them. "It's a little bit like teaching an old dog a new trick," Robey says. "When people become aware, then they'll catch on."
