"after recessing this twin gang deep box our customer wanted a chrome shaver socket instead of white plastic ! we said no problem and went to screwfix to purchase one on return to site we tried to get the shaver socket to fit into the box but couldnt ! it seems it is not deep enough to accept a flat plate chrome shaver socket ! only answer was to dig the box out of a new tiled wall and recess it further which i did ! so beware"
