2007 Nuevo bethroom sink.

Hiya all
I had one of those days yesterday. I was fixing my none flushing toilet (seized impeller). Not wanting to lose the screws I decided to put the plug in the sink when the whole metal plug hole collapsed into the sink. The metal plug hole seems to be glued onto a square plastic plate which is then glued to the bottom of the sink. Any ideas if I can fix this, and sort of glue to use or is it a new sink job? At least the toilet flush works again, I just can’t wash my hands:smile!:[You must be registered and logged in to see this link.]4
