My wall isn't square and my vanity didn't fit flush. The contractor used caulk to fill in the gap. I don't like the way it looks. I want to put up scribe moulding to hide the gap, but the base moulding is tile. How difficult would it be to remove the tile, put up the moulding and retile? I don't want to be the homeowner from H3LL but it is the first thing I see when I walk into my otherwise beautiful bathroom. Keep in mind, we haven't painted yet.
