Well this is a two part question, part one, what is the best way you have found to cut mosaic around a drain, is there an easy way? Part two: Is there such thing as a floor that is just to bad to tile?? I mean im looking at this floor, it was sloped to the drains when it was poured and there all kinds of dips and high spot all over the place and of course they want 12" tile. How would one go about fixing that? Self leveling ???
