Hi I have a plasterboard wall, where I drill two holes and placed pasterboard rawplugs in them. The first hole hit a wood baton, so that is as secure as anything. The second was just plasterboard. I inserted both plugs, then tiled the splash back. As I come to fit the sink (with pedestal), one of the plugs seems loose. What should I do? 1) Push plug through and try and get a second one through? (possibly having to widen the hole in the tile) 2) Lots of pink grip and 1 firm plug and pedestal? 3) Take off tiles, cut a hole and try to fix in some wood to the batons, to act as an anchor? (this one does seem the most secure, but hardest). What do you think?
