Measure the diameter of the faucet, soap dispenser or sprayer to determine what size hole is necessary if you don't have a paper template.
Choose a location for the faucet holes. If the faucet, soap dispenser or sprayer came with a template lay it on the desired location and mark the center.
Set a compass to the radius -- half the diameter -- of the hole and place the needle on the center mark. Draw a circle to mark the exact location of the new hole.
Fit an electric drill with a 1/8-inch bit and drill a pilot hole through the center mark. Remove the bit and replace it with a hole saw blade in the correct size for the hole.
Drill straight down through the sink top along the marked line. Remove the disk of sink top and install the faucet, soap dispenser or sprayer according to package directions.
