An open-space divided into functional areas floor plan, a back-to-back vanity floor plan and a corner freestanding tub plan are all good bathroom design ideas. For small spaces, a built-in dressing table or a combination bathtub and shower help to save room.
A good small bathroom floor plan includes a corner shower with glass enclosures, a toilet in the other corner and wall-mounted sinks or vanities along the opposite wall. You can place extra storage between or below the double sinks. To keep a small space open, opt for a wet area or a corner of the room earmarked for the shower without doors or curtains that uses a drain in the floor. Fully tiled floors and walls prevent water damage.
For larger bathrooms, a good layout idea is to space furniture in functional areas. For instance, in one corner place the vanity, mirrors and dressing table. Place the shower and tub along edges of the room, opening up the floor space. Another good idea is to add sufficient shelves and storage areas for towels and linens. To save floor room, use vertical space for tall cupboards. The homeowner can keep the toilet separate in its own compartment. Using frosted glass for the walls allows privacy while still giving the area an open, airy feel.
