This is a guess, but it looks like a metal surround. We are looking for a FP surround and our designer gave us info on the metal but I can't find the details. Look under Ion at Ann Sacks. Good luck!
love the richness of this--i think the surround is tile. u can do a spin off of this where we tile the surround and use hi gloss dark paint on the sides and cool alabaster lites
