How to Replace a Bathtub Overflow Drain Gasket · Step 9 of 9
In this video
For holes larger than fist-sized, create a custom drywall patch using scrap wood as backing. Cut a square of drywall slightly larger than the damaged area. Cut a smaller square within the larger piece, leaving a frame. Remove the inner square, creating a frame. Secure the wood backing to the wall studs with screws. Apply a generous amount of drywall compound to the perimeter and inside of the patch, then firmly press the drywall frame into the mud. Use a putty knife to apply more mud and cover the entire patch. Let it dry completely.

FAQs
Why is the estimated time for this 'beginner' project so long, and what if I don't need to cut open a wall?
The 6-hour estimate includes the potential need to cut and repair a drywall access panel, which is the most time-consuming part of the project. If your overflow drain is accessible from behind (e.g., through an existing access panel or an unfinished basement/crawl space), or if you can replace the gasket without needing wall access, the project can often be completed in under an hour.
Do I really need all the specialized drywall tools listed if I only plan to replace the gasket?
No, if you can access the overflow gasket without cutting into drywall, you primarily need a screwdriver, rags, cleaning solution, safety glasses, and the new gasket. Tools like the jab saw, joint knife, and sanding sponge are only required if you need to create and repair a drywall access panel to access the overflow plumbing behind the tub.
What are common reasons the overflow might still leak even after replacing the gasket?
A leak might persist if the overflow pipe itself is cracked or loosely connected to the tub, the new gasket isn't seated perfectly flush, or the metal flange around the overflow opening inside the tub is corroded or damaged. Always ensure all contact surfaces are thoroughly cleaned and smooth before installing the new gasket for a watertight seal.
What are the most important safety precautions I should take when replacing the overflow drain gasket?
Always wear safety glasses to protect your eyes from debris and cleaning solutions. If you need to cut into drywall, use a dust mask to avoid inhaling fine particles and a stud finder to prevent cutting into pipes or electrical wires. Ensure the tub is completely drained before starting, and if possible, turn off the main water supply to prevent accidental water damage.
