From a decorating point of view the bathroom presents a challenge. Ceiling, wall and floor materials and coverings should be impervious to water and readily and easily cleaned. The use of ceramic or glass, as well as smooth plastic materials, is common in bathrooms for their ease of cleaning. However, such surfaces are often cold to the touch and so water-resistant bath mats or even bathroom carpets may be used on the floor to make the room more comfortable.
