How to Replace a Bathtub Overflow Drain Gasket · Step 1 of 7
In this video
From underneath the bathtub, position the drain elbow assembly. Place the thick drain flange gasket over the top of the drain elbow. From inside the tub, thread the strainer body through the bathtub's drain hole and into the drain elbow. You can use a non-petroleum-based putty under the strainer flange for an extra seal. Use a drain wrench and an adjustable wrench to tighten the strainer body, compressing the gasket and securing the drain assembly.
Goal: Connect the drain pipe to the bathtub
- Can use a non-petroleum-based putty or sealant between flange and bathtub.
- This step may require two people, one to hold the assembly from below and one to tighten from above.

FAQs
How difficult is replacing a bathtub overflow gasket, and what's a realistic time commitment for a beginner?
This is considered a beginner-level plumbing DIY project, primarily involving simple disassembly and reassembly. While the estimated time is 2 hours, allow yourself extra time, perhaps 3-4 hours, especially if the old gasket is stubborn or significant cleaning is required, to avoid rushing.
What should I do if my bathtub overflow still leaks after replacing the gasket?
First, ensure the new gasket is properly seated and the overflow cover plate screws are tightened snugly, but not overtightened, which can warp the plate. If the leak persists, carefully inspect the mating surfaces for any remaining debris, cracks, or imperfections on the tub itself or the overflow pipe that could be preventing a complete seal. You might need a thin bead of plumber's putty or silicone sealant around the edges of the gasket if the surface is uneven.
Do I need all the specific tools and materials listed, or are there acceptable alternatives?
The multi-screwdriver is essential for removing and reattaching the overflow plate. While specific brands are listed, any multi-purpose screwdriver with appropriate head sizes will work. For cleaning, an all-purpose cleaner and rags are crucial; the specific brand isn't critical, but a hydrogen peroxide-based cleaner is effective. The utility blanket is mainly for protecting surfaces, which can be substituted with old towels or cardboard.
What's the best way to remove an old, stubborn, or brittle overflow gasket without damaging the tub?
After removing the cover plate, carefully use a small, flat-head screwdriver or a utility knife to gently pry out the old gasket, working slowly around its edges. If it's very brittle, it might break into pieces, which is fine; just ensure all fragments are removed. Take extra care not to scratch the tub's finish or the overflow pipe's surface during removal.
