I have a shower that's leaking from the corner. Basically, as can be seen from the picture, it falls through into the crack and then the water goes behind tiles and comes out the floor right outside the shower cubicle.
The house is 8 years old and I've just bought it. It doesn't look like there's any damage I can see from inspecting the wall. Should I just seal up the hole with silicone sealant? Do I need to somehow dry the inside behind the tiles?
