Sealing leak in glass shower door

[Quinlad]

Hello.

We've put a glass shower door in but it leaks very badly from the bottom of the door, at the point where it hinges.

The guy who installed it did put in some kind of silicone (I think) but it hasn't made much difference. He also suggested that the bath is slanted in that direction anyway.

What should we do? Put some more in? Or use something else?

Any ideas?

Ta.
