Unlike some shower and kitchen faucets, which feature a third handle to control a diverter valve, bathroom faucet housings feature only one- or two-handle designs. Single-handle designs are equipped with cartridge faucets while dual-handle designs use compression faucets. Cartridge faucets are one-piece designs that cannot be disassembled, but replacement cartridges usually cost only a few dollars. By contrast, compression faucets can be disassembled and repaired.

Things You'll Need

  • Screwdriver
  • Pliers (single-handle faucets only)
  • Handle puller (dual-handle faucets only)
  • Wrench (dual-handle faucets only)
  • Utility knife (dual-handle faucets only)

Single-Handle Faucets

Turn the water off at the two shut-off valves below the sink.

Remove the screw from the middle of the faucet handle with a screwdriver. Lift the handle off the faucet.

Remove the metal clip from the top of the faucet by pulling the clip away with pliers.

Pull the faucet out of the faucet housing.

Dual-Handle Faucets

Turn the water off at the two shut-off valves below the sink.

Remove the screw from the middle of each faucet handle with a screwdriver. Lift the handles off the faucets. Remove a corroded handle with a handle puller. Compress the two jaws at the bottom of the puller around the base of the handle. Turn the handle at the top of the puller in a clockwise direction to draw the handle off the faucet.

Remove the large nut that surrounds the base of the exposed-portion of the faucet with a wrench. Life the faucet out of the faucet housing.

Remove the screw from the bottom of the faucet with the screwdriver to free the rubber washer. The washer helps prevent the faucet from leaking.

Cut the rubber O-ring off the lower half of the faucet with a utility knife. The O-ring works in conjunction with the rubber washer at the bottom of the faucet to prevent leaks.
