sink is 'unstuck' from Wall. I'm assuming I need to use caulk?
Pedestal Sink Pulled From Wall
So I leaned on my powder room pedestal sink. It pulled from the wall. How do I reattach it?
the shift also screwed up the drain cover
Either the bolts pulled out if the wall or the bracket got bent. Look underneath and see how yours is attached to the wall. If the bolts are lose try to tighten them. If it hangs on a bracket, it probably bent. You will need to remove the sink. The drain cover cracked. You will need to replace the drain assembly.
Just an overview on removing and installing a pedestal sink. More of a guide where components are.
