Have an older fiber-glass (I think) shower stall.
Want to replace the flat cover plate with the slots that covers the drain hole. Thought it was the typical thing with two screw holes, and about 3" in Dia.
But, surprised to see that's it is around 4" in diameter, and NO screws or screw holes in the plate.
Don't want to break anything by forcing it up.
How are these things (likely) fastened, therefore ?
- epoxied in ?
- some kind of simple expansion clamp that will allow the plate to come up if forced, just a little ?
Really don't want to break anything down there.
