How to prevent shower water from leaking from the side of glass shower door
did you ever resolve this? If not, then may I suggest that you need a seal that runs down the hinge side of the shower door.

It looks like you have 8mm glass SO you would use a PCR8 From CR Laurence.


You can find them here

They are a simply push on seal that you can run from the top of the glass right down to the bottom, you would have to cut the seals where the hinges are but thats about as technical as you get.
