upstairs bath . Create long lines. Whether your bathroom is a typical rectangle or more oddly shaped, you can usually find one wall or area that’s a bit longer than others to emphasize. Adding a shelf, a band of tile, a molding chair rail or another long element (even a simple stripe of paint) can help emphasize the longest line in your room and draw the eye to the widest point. In this room, the encroaching low ceiling is de-emphasized by the wide shelf and tile backsplash that highlight the widest point just below where the slope begins.
