Hi there\n\nI have a leak someone underneath my upstairs bathroom sink which is dripping down into the ceiling. We've stopped using the sink but I need to get underneath and see what's leaking. The problem is I can't work out how the access tile has been attached to the wall and I can't remove it so far. The bathroom is about 3 years old and was installed as part of my new build.\n\n[IMG]http://i65.tinypic.com/27zm8lv.jpg[/IMG]\n\nI've used a box cutter to cut a gap around the silicon sealant around this tile (all the other tiles have conventional grouting) but I can't seem to remove it. I don't understand how tiles like these are conventionally attached beyond the sealant. Is it screwed or fixed to something behind the tile? Do I need to smash it to get it out?
