We have a 36" x 60" space that we would like to put a 30" x 60" drop in tub....this would give us a tiled front and 6" lip/edge but the 2 sides and back would be butted up to the walls. The walls would be tiled, so the tiles would butt up to the tub....is this a bad idea??? We are going for a very modern look and this would help us achieve the look we want but not sure if this type of installation will work. We really do not want a slide in! Any help, advice would be greatly appreciated!!!
