It is approx at the same level as the top of the bathtub where the silicone bead is against the tiles. The whole wall is tiled.
My question is what do I need to fix it
Is it likely that silicon needs to be re-done? The silicon looks pretty good shape, it is about 4/5 years old
Do I need to take the bath panel off to take a look underneath in case a pipe is leaking? If so how does one take off the bath panel?
The bathtub and panel is made of Carronite
