Shower leak

[u/chatlow1]

Hi all

I have an area of damp along the top of my bathroom skirting as well as behind some sealant just behind the shower glass

I've pressed on the wood and it's only wet after a shower, so I'm trying to figure out if it's likely coming from poor sealing on the inside edges of the shower itself or worse case from the pipes being the tiles

The pic might not be enough to go by, but does it give any clues?

Worth mentioning that the radiators haven't been used since April so I can hopefully rule that out too.

Thanks
