The building code of the United States and Canada requires the full circuit interrupter electrical sockets to prevent electric shocks which may be caused by the electrical appliances installed in the bathroom like the lights, heaters and heated towel rails.  This requirement should be part and parcel of the bathroom design.

Minimal clutter found in the bathroom should be observed in the bathroom design.  A pedestal sink can save space and make the room look larger rather than cramped the space with the large vanity or countertop.  Mirrors, too, can make the bathroom look bigger as they capture and reflect light inside the bathroom.  To make the bathroom appear bigger, soft colors of tiles and light-colored floor mat or carpet should be selected.

Whether a house has a small bathroom or an elegant one, the bathroom design should serve as relief room with sanitation as its first and foremost consideration.
