Replacing a faucet usually requires, slot head and phillips head screwdrivers, a set of locking pliers, a bucket, some towels, and lots of patience. You'll need to turn off the water supply valves beneath the sink, disconnect the water supply lines from the water valves then remove the old faucet assembly. Follow the manufacturer's directions for installing the new faucet. Expect to spend 1-2 hours on the project if you don't have experience replacing faucets. An experienced plumber can usually complete the job in 30 minutes.
