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.
