A bathroom represents purity, cleansing of ideas or attitudes and physical elimination. This is particularly true when attention is not drawn to a specific device in the bathroom.
In dreams about the physical body the bathroom can also symbolize the liver, kidneys or colon. Emphasis is often given to specific items in the bathroom in this case. In this case the bathroom taps would symbolize your kidneys. The waste pipes and drains represent your colon. The toilet bowl represents your bowel. Any sort of straining device, particularly one using organic material would indicate your liver.
Bathroom walls indicate the walls of your intestines. If the paper or plaster is falling off the walls it indicates the lining of your intestines is damaged.
