Replacing sealant between fixed glass shower screen and bath

bathroomsealant

I have a shower screen in the bath that looks similar to this:

There is a shower screen seal vertically between the hinged portion and the door and beneath the bottom of the door which are both working well.

Beneath the fixed glass portion though, there is a rubbery seal that's coming away from the glass & I want to replace it, but I'm not sure exactly what I'm looking for.

It's transparent and it looks similar to silicon caulk, but it seems much thicker. It's all coming away in one portion. I'd hazard that it's some type of tape, but I'm not sure what I'm looking for?

I was thinking of trying to replace it with 'regular' silicon caulk but I'm worry the gap underneath the fixed glass may be too big for it.

I guess my question is — can anyone tell me what I'm looking for from my vague description? (I'll try to post a photo of the actual bathroom/sealant when I can!) I've searched for bathroom sealant/bathroom tape/trasparent rubber sealant etc. but I'm none the wiser.


EDIT: Adding a picture of the seal that's coming away:

The strip falling off looks like rubber. A U shaped rubber gasket that maybe split and is coming apart on both sides. If the glass is resting on the tub and this was supporting its weight you need to remove the door and replace the gasket.

If the wall brackets are supporting all the weight there should be a gap between the tub and the glass that you can fill with clear silicone. It should ooze through to the other side when you inject it, then you shape it flush with the glass on both sides, no curve, and it looks like the glass is sitting on the tub.

But it should not have lips with edges on the sides of the glass like yours. That's why I don't think yours is silicone.

Another thought if you use silicone to fill a gap between glass and tub: If you do not remove the door, it will be hard to clean the tub thoroughly under the glass. You may in that case want to use white silicone to match the tub rather than clear. It will still look great. I've seen clear silicone used between adjacent panels of a glass wall, filling a gap about 6mm. Looks great. But with the white tub you could use white.
