I want to put wood look porcelain planks on my stairs. I am not crazy about the Schluter look. My installer said we could use a white oak, stained to match, outside corner mould on the edge and butt up to it with the tile. He has used custom pieces, 2" x 1 5/8" (the 2" on the tread, 1 5/8" on the riser) that are 3/8" thick. We live in Nevada where it is too dry to use wood treads. Do you see any problem with this approach?
