If I install new concrete board and new tile for the bathroom, obviously I need toilet flange extension. The questions:
1. Do the flange must be on top of the tile or just on top of the concrete board is good enough?
2. Do I need to cut the tiles perfectly around the flange? Or just a square hole is OK?
3. Do I need to put caulking or anything like that around the new flange extension?
