How to Replace a Bathtub Overflow Drain Gasket · Step 6 of 7
In this video
Move to the overflow opening. From the back of the tub, apply a bead of silicone sealant around the overflow opening where the gasket will sit. Place the overflow gasket onto the overflow fitting and press the fitting against the back of the tub, aligning it with the holes. From the front of the tub, position the metal retaining plate, making sure the open slots face upwards to allow water flow. Insert the two long screws through the retaining plate and into the overflow fitting. Tighten the screws evenly to compress the gasket and create a seal.
Goal: Seal and secure the overflow
- Ensure the open slot on the retaining plate is facing up. This allows water entering the overflow to drain properly.

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.
