Holes: The number of holes in the sink will determine the faucet configuration. Sinks will have between one and five holes drilled into them to accommodate the faucet, handles, spray, soap dispensers, etc. If a new faucet is installed in an existing sink, the number of holes and configuration has an impact upon the faucet. A deck plate can be purchased to cover the holes, if a single handle unit is desired. If the sink is installed with the faucet, the sink can be chosen to accept the faucet, or the countertop can be cut to fit.
Purpose: If cleaning or filling tall pots is a function, a tall faucet will be desired. If a prep sink needs a faucet, a pull-out or shorter faucet may accommodate.
Lifestyle: If cooking is a family activity and several generations of the family will be using the faucets and sink, consider the ages and height of the family members. Wall units are interesting, but may not be reached by the very young or the older generation. If the individuals using the faucets are older, install an ADA appropriate type of handle, such as a lever or touch-activated faucet.
Space: Counter space often is a premium. Several space saving options are available, such as wall-mounted faucets. Shelving or a cabinet over the sink may limit the height of the faucet to be used.
Architectural Style: Faucets are available in a variety of styles and designs, so purchase one that coordinates with the room style.
