A cleaning tool is connected to the end of a shower hose after a shower head has been separated from the end of the shower hose, and tap water can be supplied to a surface to be cleaned, such as a bathroom wall or floor, so that bathroom cleaning may be easily carried out even by a user's one hand in a convenient way, thereby minimizing the user's power consumption and shortening cleaning time, and further, the cleaning tool may be conveniently fastened and separated to and from the end of the shower hose by means of a single touch, so that a cleaner for cleaning the surface to be cleaned can be simply exchanged with the shower head, thereby improving the conveniences of use.
