Just a quick question for anyone who would know -- about the splash problem with wall mounted faucets. Can you just attach a diffuser to the spout? From the ones I've seen, they just screw into the end of most faucets. I guess the question is do all faucets have threads at the spout? I'm dying to do a remodel of our powder room and would love to do a wall mount on granite tile. Anyone have any experience with that? One picture I've seen showed the two tiles with the spout centered on the line between the two tiles with the handles to the right and left. I was thinking that would be easier for the granite cutting to put the spout in the center on the edges with two round holes on the corners.
