I need your help. I'm about to start laying cut stone veneer on my fireplace surround. I will be mounting my flatscreen above the mantel. I have two single gang boxes mounted on the wall currently with a stud's witdth between them. I need some suggestions on how I can finish these when I bring my stone up. One box is for power. The other box is for my hdmi and cable. I've looked into box extenders, but they don't seem to work with the junction box that has the hdmi/cable. The other issue with the box extenders is that I can't seem to get the extension out far enough as this cut stone averages 2-3in in thickness. If there is an extender that is better suited for this, please recommend. I also looked into stone veneer outlet pieces, but these are too large( I have an inch and a half between boxes). I'm ok with recessing the outlets in the stone surface, but I'm not sure how to do it. Can just stone around the perimeter of the finished outlets? Thoughts?
