A wall kitchen faucet mounts directly to your kitchen wall. This type of faucet is a staple in commercial kitchens and some homes. Wall Kitchen Faucets allow for increased height to create a more unique look for the home kitchen and fill larger sinks while taking up less countertop space. Wall Kitchen Faucets come in a variety of finishes and styles and require water supplies that extend above the countertop in the wall. Although it's mounted differently from a typical in-home kitchen faucet, it's repaired in basically the same way.
