13. The Hidden Powder Room Bathroom
Adding a powder room is one of the best ways to increase your home’s value and convenience. The space under a main staircase is often just large enough to accommodate a toilet and a small hand-washing sink. Because space is at a premium, opt for a wall-mounted toilet with an in-wall tank and a compact, wall-hung corner sink to maximize precious floor space.
Since this is a small, self-contained room, it is the perfect place to make a bold design statement. Embrace the cozy scale by applying a dramatic, large-scale floral wallpaper or a rich, dark paint color. Install a large, beautifully framed mirror above the sink to visually expand the room, and use high-end brass or matte black fixtures to add a touch of modern elegance. Proper ventilation is essential, so be sure to install a quiet, efficient exhaust fan vented to the exterior.
