We're in the process of buying a house, and in it, the fireplace is just a gas insert with no surround or mantel, just an opening in the wall above the fireplace. We're wanting to cover the opening (well supported with additional boards) with ship lap and mount the tv there. I definitely want a nice sized mantel and to do a tile surround. But does it need a full surround that's a part of the mantel, beyond the tile? I'm not having much luck in finding examples of just tile below the mantel. Attached is a listing photo. (We won't have such large/heavy furniture in the space)
