Has anybody ever used a window mural (whether it be a wallpaper product or a tile product)? I would love to use one on the wall behind a freestanding bathtub, but I am afraid it will look cheesy and cheap. It's for an upscale master bathroom; I would like to have a window mural looking out onto the ocean. I'm afraid to even ask our decorator about this. Have any decorators out there ever used one or seen one? Thank you.
