How to Repair a Tub and Shower Disk Faucet
This common bathroom feature may need repairs from time to time. Here's how to get the job done.
This faucet works like a sink cartridge faucet and repairs are similar.
If water drips out the spout or seeps out around the handle, buy a kit and replace all the rubber parts. Inspect the cylinder and replace it if you see signs of wear. If your model has plastic rather than ceramic disks, replace the entire unit.
Depending on the model, you may need to partially disassemble the cylinder to get to all the rubber parts.
What You Need
- Adjustable wrench
- Groove-joint pliers
- Cleaning brush
- Repair kit for your model of faucet
- Silicone grease

Ceramic-disk faucets have two disks, which may be ceramic or plastic, housed in a plastic cylinder. If the disks are damaged, replace the entire cylinder.
Step 1: Remove Handle and Cylinder
Shut off the water and turn the faucet on until water stops flowing. Remove the handle and the escutcheon. Unscrew three screws to remove the cylinder.
Step 2: Replace Seats
Remove rubber seats with your fingers. Clean the openings with a cleaning brush, such as a toothbrush. Replace the rubber seats with duplicates. Rub a bit of silicone grease over the seats.
Step 3: Continue Cleaning
Do the same for all other rubber parts. If you need to pry out an O-ring, try using a small screwdriver. Work carefully to prevent nicking the plastic housing.
