We have a bathub/shower that needs a new surround-
The walls are currently a cheap-o surround kit, and ~suprisingly~ water
is getting in behind the walls causing mildew.
We want to take this out, and replace it with tile. My only question
is regarding the joint between tile and bathtub. Currently, there is a
small 1" lip on the tub, the surround is overlapping this lip. When
removed, how do we make the joint between tile and the lip? It is a
steel tob, and the lip is just a thin piece. Should I tile ove rit?
Or is there some option I don't know about.

I am a HOME REPAIR newbie!

Thanks!
