I have an acrylic (maybe fiberglass) shower/tub enclosure. It leaks when the shower is in use, causing a stain to appear on the ceiling of the room below. The most likely culprit appears to be that there is a gap where the tub faucet comes out from the wall, maybe 1/4'' (the faucet is not flush with the enclosure buy that amount).
Is this likely to be the cause of the problem? If so, how could it best be repaired? I am inclined to try silicone caulk but the gap is fairly wide and I worry that it may look bad.
Edit: yes, by "tub faucet" I mean the pipe that the water comes out of when you're filling the tub.

I fixed the problem so I may as well answer my own question.
The spout was detachable from the pipe (it is held on by a mechanism which can be loosened by a hex wrench -- the nut is on the underside of the spout)
Once the spout is removed, you can caulk the gap where the pipe goes through the hole in the shower enclosure, and then re-attach the spout. There's no need to caulk around the spout itself.
between it and the enclosure, though that's more of a cosmetic
improvement than anything else.
There is a video of someone doing this repair here.
