To remove and replace a kitchen faucet handle for better functionality, start by turning off the water supply. Unscrew the set screw on the handle, typically located underneath or at the back. Remove the old handle and install the new one by aligning it correctly and securing it with the set screw. Turn the water back on and check for proper operation. A new handle can improve ease of use and aesthetics.

Upgrading to a new handle can improve the ease of use and enhance the overall functionality of the faucet. A well-installed handle provides smoother operation and can match new faucet designs, offering both practical and visual benefits.
