Summarize the following:
A small bathroom doesn't need too many decorations; your paint color, a pretty bathroom mirror, and a picture or two will be enough to create a functional, relaxing space. Avoid hanging large posters, light fixtures, or anything that sticks out from the wall too much. Hanging up your towels, putting your clothes in the hamper, and keeping books and magazines on a shelf can make your bathroom appear to be more spacious. In addition, go for a thin, subtle bathmat instead of a big, fluffy one, which can make the floor appear cluttered and small.

Summary:
Decorate sparingly. Keep items off the floor.
