I have a bathroom window over a tub that is in similar need of a a tile backsplash. The window was replaced and I asked the window guys to add 3/8" to the jamb. My plan was to tile to the jamb, and then trim over the tile. The tile will wrap partway up the window and the trim would sit on top of it, leaving some of the tile exposed. For the part up the wall where there isn't tile, the trim would have some sort of backing added to increase the depth where it meets the wall. Does this sound wonky?
