I would use a nylon screw plug in the drywall and JB Weld epoxy under the

The bracket is not tall enough to require a nylon anchor into the
sheet rock? Two long screws will get the OP into solid wood at the
base 2X4 plate.

One hole in the porcelain will get him aligned (measure twice) for an
anchor screw. Epoxy would be messy and difficult to align the door for
the correct reveals on each side. Too many chances of movement.

The bracket is perpendicular to the wall, not angled or diagonal.
