How to Remove a Faucet
Step #1: Clean out the cabinet under the sink to allow room to work.
Step #2: Turn off the water supply to the faucet at the cut-off valves under the sink, then turn on the faucet to see if water has stopped flowing. If the water lines under the sink do not have cut-off valves, turn the water off for the entire house at the water meter or where the main water line enters the house in the basement.

Step #4: Unscrew the hold down nuts under the countertop that secure the faucet in place using adjustable pliers or a special basin wrench.
