I am remolding our master bathroom that is only a shower and toilet. Our shower is only 3ftx3ft. I want to do the carrara marble that is 6x12 staggered on the walls and ceiling and possibly carrrara marble hexagon mosaic tile on the floor. Im am not sure if this will look right. I have a ninch to fill too but not sure what tile to put in the ninch or just run the 6x12 or the hexagon tile in the ninch. Can someone give me some suggestions please. Also what tile should i put on the out side walls of the shower by the toilet and on the outside shower floor?
