Moving sink, backerboard around toilet drain
I had a leak around my toilet flange, I pulled out the carpet and toilet and the flange is in fine shape. I intend to do a light remodel of the bathroom. The first thing I want to do is to install a slightly larger vanity and move the center of the vanity over a few inches. The result will be that the center line of the sink will move approximately 6" - 8" to the side. Do I need to make any special considerations for this move when connecting to the drain that is, obviously, not moving with the vanity?
How does one install backerboard around a toilet drain? If you leave any space between the flange and the backerboard and you have a leak, won't all of the water go straight to the subfloor without giving you water on the tile to indicate that there is a leak? I was going to install a flange extender, but this only increases the height of the flange. Do I need to remove the current flange, install tile, then install a new, deeper flange?
Thanks in advance for the help.
