8 Easy Steps on How to Replace Delta Shower Handle
Step 1: Turn Off the Water Supply
Before you start removing the old shower handle, it’s essential to turn off the water supply. This step prevents water from spilling or causing a mess during the replacement process. Typically, you can find the shut-off valve for your shower near the main water supply. Turn the valve clockwise to ensure the water is completely off.

If you cannot locate a specific valve for the shower, you should turn off the entire home’s water supply. Once the water is off, test the shower by turning the handle to confirm no water is flowing. This precautionary measure ensures a safe and hassle-free replacement process.
Step 2: Remove the Old Handle
Using the flathead screwdriver, locate and remove the screw holding the old shower handle in place. This screw is typically found on the underside or front of the handle, sometimes concealed by a decorative cover. If there’s a cover, gently pry it off with the screwdriver to reveal the screw. Once the screw is exposed, unscrew it completely and set it aside in a safe location to avoid losing it. Carefully slide the old handle off the cartridge stem, ensuring not to force it, as this could damage the stem. This step prepares the area for installing the new shower handle.
Step 3: Prepare for the New Handle Installation
Before installing the new shower handle, inspect the cartridge stem for any signs of wear, corrosion, or debris. Clean the area around the stem with a cloth to remove any buildup or residue that may interfere with the installation. If the stem appears damaged, consider replacing it to ensure optimal performance. Verify that the replacement handle matches the cartridge stem and fits securely. This preparation provides a smooth installation process and helps avoid issues with functionality after the handle is installed.
Step 4: Install the New Shower Handle
Position the new shower handle over the cartridge stem, aligning it according to the manufacturer’s specifications. Gently slide the handle onto the stem without applying excessive force. Once the handle is in place, secure it by tightening the screw you set aside earlier. Use a screwdriver to tighten it firmly, but be cautious not to overtighten, as this could damage the handle or the stem.
Finally, reattach the decorative plate or cap to cover the screw, ensuring a neat and finished appearance. Test the handle by turning it to verify smooth operation and proper functionality.
Step 5: Turn the Water Supply Back On
Once the new shower handle is securely installed and tested, it’s time to turn the water supply back on. Slowly open the water valve to allow water to flow into the shower system. Check for any leaks around the handle or connections, ensuring everything is sealed correctly.

Turn off the water supply and tighten the necessary components if you notice any leaks. After confirming that there are no leaks and the handle operates smoothly, your installation process is complete. Enjoy your updated and functional shower handle!
Step 6: Clean Up the Work Area
With the installation complete and the shower handle functioning correctly, take a few moments to clean up the work area. Dispose of any packaging, old parts, or debris from the installation process. Wipe down the handle and surrounding surfaces to remove fingerprints or water spots, leaving the area looking tidy and polished. This final step ensures a professional finish to your project and prepares your bathroom for regular use.
Step 7: Perform a Final Test
Before considering the complete project, perform a final test of the shower handle to ensure everything functions as expected. Turn on the water and adjust the handle to test temperature control and pressure. Observe the shower system briefly to confirm no drips or unexpected noises. If any issues arise, address them promptly by referring to the installation instructions or consulting a professional. A thorough final test ensures your new shower handle’s durability and proper operation.

Step 8: Enjoy Your New Shower Handle
With the installation and testing complete, it’s time to enjoy the fruits of your labor. Take a moment to appreciate your updated shower system’s improved functionality and aesthetics. Regular maintenance, such as cleaning and periodic inspections, will help extend the life of your shower handle and ensure optimal performance for years to come.
By following these easy steps, you can confidently replace your Delta shower handle and personalize your bathroom to your desired style.
5 Things You Should Avoid
- Skipping the Water Shut-Off: Never attempt to replace the shower handle without first shutting off the water supply. This can lead to leaks, water damage, or even flooding during the repair process.
- Using the Wrong Tools: Avoid using improper tools as they can damage the shower handle or surrounding components. Ensure you have the correct wrench, screwdriver, and other necessary tools before starting.
- Forgetting to Keep Track of Parts: It’s crucial to keep track of screws, washers, and other small components when disassembling the handle. Losing a part can delay the process or compromise the reassembly.
- Applying Excessive Force: Forcing parts off or over-tightening screws can cause damage to the handle or internal components. Always work carefully and follow the manufacturer’s instructions for proper disassembly and assembly.
- Skipping Seal Checks: Avoid skipping a thorough check for leaks or improper sealing after installing the new handle. Failing to do so can result in water dripping or inefficiencies over time. Always test the handle before finishing the job.
What are the Causes of a Leaky Shower Handle?
A leaky shower handle is a common plumbing issue caused by several factors. Here are some potential causes to look out for when troubleshooting your leaky shower handle:
- Worn Out Washer: The washer in the handle’s valve stem can wear out over time, leading to leaks. It is essential to replace worn-out washers promptly to prevent further damage.
- Loose or Damaged O-ring: An O-ring is a rubber seal inside the valve stem that prevents water from leaking. If it becomes loose or damaged, it can cause water to drip from the handle.
- Corroded Valve Seat: The valve seat connects the faucet and the spout. If this becomes corroded, it can cause leaks as well.
- Faulty Cartridge: In some cases, a defective cartridge may cause a leak in your shower handle. This component controls the water flow and temperature, so if it becomes damaged or worn out, it can result in leaks.
- Improper Installation: If the shower handle was not installed correctly or has been installed with incorrect parts, it can lead to leaks over time.

Conclusion
How to replace Delta shower handle is a manageable task that can save you money on professional repairs and prevent further damage caused by leaks.
Begin by identifying the root cause of the issue, such as a worn washer, damaged O-ring, or faulty cartridge. Always gather the necessary tools and replacement parts before starting the repair. Follow the manufacturer’s instructions or a reliable step-by-step guide to disassemble and replace faulty components safely. Ensure all connections are secure and test the handle for proper functionality after reassembly.
With careful attention to detail, this DIY repair can restore your shower handle to optimal performance.
