I am planning to build an ornamental (as in no fire beyond a candle or two) fireplace in my living room, and I want to face it in subway tile. It's basically going to be a knee wall mounted in front of the existing wall with a salvaged oak mantle over the top. But I really have no constraints on materials/construction to speak of. Given that, what would be the best way to face the knee wall and adhere tile to that facing material?
Thanks for your input!
