Design for small Bathroom

Design a floor plan that maximizes the room's useable space. Don't be afraid to design up by incorporating free-floating cabinets. Use mirrors to stretch a small bathroom's space, and keep the color scheme simple. Keep a small bathroom bright, fresh, and inviting with coordinated colors and accessories. Pare down the scale in your bathroom. Big items take up more space in the bathroom and look bulky. Corner sinks are simple and small. These sinks free up visual space below, but don't provide the counter space and cabinet space that a traditional sink provides. Another option is a pedestal sink.
A simple way to conserve space is to do away with a tub and just use a shower. Smaller tubs, however, are available, although most cannot handle whirlpool faucets. Any tub less than five feet long will probably spill the water sprayed by the whirlpool faucets. Pick a toilet that can sit close to the wall to conserve space, and the size of the seat and tank design determine just how much space the toilet will use.
Finally, limit what you bring into the bathroom. To save space in a cramped bathroom, for example, it may be best to have a dressing area in a bedroom. Limit the number of accessories -- clutter can easily make a small bathroom look smaller.
