![]() ![]() The quartz installer I used didn't have the box cuts perfect so they had to be adjusted to allow the box extenders to fit into the back splash. The advantage of the white box extender when you have a thick back splash that is quartz is that you don't need to cut the corners perfectly for the box extender to fit into the hole. Looks like based on the referenced answers that boxes can only be 1/4" recessed from non-combustible surfaces. The back splash is not always tight to the drywall surface so the box extender helps seal or bridge this gap. I had a 3/4" quartz back splash installed and we used box extenders. your tile is over 1/4"), you can make it compliant with an extension ring that does indeed use long mounting screws. The simple answer is that, if the box is flush with your mounting surface, it might be compliant as-is after tiling. This necessitates something important: you must cut the tile to allow access to the box. Then the builder will either put drywall or some sort of backer board up. Assuming you have new construction, your electrician will come in first and wire everything up, with the box as close to the surface as possible (usually, some do cut corners here). Most tile or backspash is 1/4" when it's done (thin set + tile). Installations within or behind a surface of concrete, tile, gypsum, plaster, or other noncombustible material, including boxes employing a flush-type cover or faceplate, shall be made so that the front edge of the box, plaster ring, extension ring, or listed extender will not be set back of the finished surface more than 6 mm (1∕4 in.).
