A small bathroom can be a hassle if not designed well and Functional Bathroom Design ideas are of great help. A bathroom can be a busy space with the sink, the commode and the bathing tub/ area. Maximizing the small space for a functional bathroom is a creative task. If anything takes more surface space than required, revamp it. A tall and sleek sink would be a good option to de clutter the space. The bathtub can be small or skipped altogether. Use a shower space instead. A lighter shade on the walls and large tiles on the floor create an illusion of more space. For storage, use bracketed glass shelves.
