Some single-handle faucets use levers, which can be easier for children or people with arthritis to use. Quality is the first thing to consider when purchasing a faucet. You don't necessarily have to buy the most expensive faucet, but you want to be sure that it will give you trouble-free service for several years. The next factor to think about is size. Larger faucets don't use escutcheon plates, the decorative covers that conceal the inner parts of the faucet.
Smaller faucets are available both with and without escutcheon plates.
If the sink is damaged or corroded under the existing faucet, you'll probably want to choose a replacement with an escutcheon plate. Once you've determined the size and type of faucet you want, choose something that harmonizes with the decor of your bathroom. All of the metal fixtures in your bathroom should match. Polished chrome, for example, doesn't mix well with antique brass.
