thats because you dont drill thru tile lol, your supose to use a grinder and cut a small hole to allow the screw to pass. what did you drill into it anyway? also pick yourself up a tube of latex just pass it along the top between the tile and cealing. use popsicles stick or your finger, (i prefer my finger) and wipe it across the top to fill the holes and make it nice and indented. oh also if you use your finger wash your hand then lick your finger. your saliva will prevent the latex from sticking to your skin, and its a pain to get off. then you will go from home renovation to proffesional looking. that line between the tile and the cealing is a litle of an eye sore, and i must say I'm very impressed to see some one lay shower tile for there first time, and this well. especialy on a 45.
