A leaky shower can be annoying — the constant drip, wasted water, and higher utility bills. If you have a Delta faucet, one common cause is a worn-out gasket. Fortunately, learning how to change the gasket on a Delta shower faucet is a straightforward DIY repair that saves you money compared to calling a plumber.
What Does the Gasket Do?
In a Delta shower faucet, the gasket (or O-ring/seal) creates a watertight connection between parts of the valve and spout. When it wears down, you may notice:
- Dripping from the faucet when it’s off.
- Water leaking around the handle or escutcheon plate.
- Reduced water pressure due to internal leaks.
Replacing the gasket is often all it takes to restore your faucet to like-new condition.
Tools & Materials You’ll Need
- Replacement Delta gasket or O-ring set (check your model number).
- Screwdriver set (Phillips and flathead).
- Allen wrench (for handle removal).
- Adjustable wrench or pliers.
- Plumber’s grease.
- Towel or bucket (to catch drips).
Step-by-Step: How to Replace the Gasket
- Turn off the water supply. Locate the shutoff valve near your shower or turn off the main water line.
- Remove the handle. Use an Allen wrench or screwdriver to remove the handle screw and pull the handle off.
- Take off the trim plate. Unscrew and carefully remove the escutcheon plate to access the valve.
- Access the cartridge and gasket. Depending on your model, the gasket may be part of the cartridge assembly or located behind the valve body.
- Remove the old gasket. Use pliers to carefully pull out the worn gasket or O-ring. Take note of its orientation.
- Lubricate the new gasket. Apply a thin layer of plumber’s grease for a smooth fit and longer life.
- Install the new gasket. Insert it into place, making sure it seats evenly.
- Reassemble the faucet. Replace the cartridge (if removed), trim plate, and handle.
- Turn on the water and test. Check for leaks. If water flow is smooth and leak-free, you’ve done the job correctly.
Tips for Success
- Always use genuine Delta replacement parts for the best fit.
- If you’re not sure of your faucet model, remove the handle and look for a part number or bring the old gasket to a hardware store.
- Replace washers and O-rings at the same time for a complete refresh.
When to Replace the Entire Faucet Instead
Sometimes a new gasket isn’t enough. Consider replacing your shower faucet if:
- The faucet is more than 10–15 years old.
- Leaks persist even after replacing gaskets and cartridges.
- You want to upgrade to a modern design with better efficiency.

FAQ
1. How do I know if my Delta shower gasket needs replacing?
If water drips even when the faucet is off or leaks around the handle, the gasket is likely worn out.
2. Can I replace just the gasket without replacing the cartridge?
Yes, but it’s often smart to replace both if your faucet is older to avoid future leaks.
3. How long does a Delta shower gasket last?
Typically 7–10 years, depending on water quality and usage.
4. Do I need special tools?
No — just common household tools like a screwdriver, wrench, and plumber’s grease.

With the right tools and a replacement gasket, most homeowners can complete the job in under an hour. But if your faucet is old, replacing it entirely with a new Delta model may be the smartest long-term solution.
