My plasterboard boxes are approximately the same width and height as the sockets. The sockets have bevelled edges. Most YouTube guides I've watched recommend leaving a few mm gap between the edge of the box and tile, but that applies to metal back boxes which are somewhat smaller than the plasterboard ones and flush, so the socket covers the tile edges when screwed back on, The flange on plasterboard boxes is about a mm and a bit proud of the surface, so I'm wondering if the edge of the tile sitting on top would raise it so much that it would be noticeable? The alternative is to just tile up to the sockets, but since the edges are bevelled, that would look ****.
