I’m at a loss!
We have a leak in the corner where the shower glass meets the wall.

It had been leaking slowly and was behind a rubbish bin so ended up damaging the gib.
I ripped out the wet gib and old silicone, and then left it open for a few days to check for leaks.
No leaks! (Or so I thought)
After using filler and letting that dry, and then painting a primer coat, tonight i see it is wet…
I cant for the life of me think of where this water could be coming from.

Any suggestions? There is no silicone on the glass wall or door on the inside, but the other walls have new silicone.

Im wondering if water may be leaking down behind the mixer. Hope not.
I could use some advice please
