Can really use some ideas with how to finish our fireplace. It is currently demoed, so no pics of the actual space that would be helpful (removed wood burning double-sided fireplace, replacing with a 6 ft x 20 in gas stellar enlight pier fireplace that will split my dining room and living room spaces). The picture below is what I am trying to replicate (minus the TV; top and bottom will be same color with small section of black in the midsection extending from the insert). I like the clean, minimalistic look. The bottom is wider than the top by 3" on all three sides, like in the picture; the top will be flush with the fireplace glass. First considered using large format porcelain tile (48x110", cerrad softcement white) with mitered edges (found a specialist who will do this, very expensive given all the mitered edges) but given the expense, wondering if there is a better option. Anyone use concrete/microcement to achieve a similar uniform look that they're happy with? Other paneling? Different tile? I really want it to look seamless without grout lines. Thanks in advance for any advice.
