PROBLEM TO BE SOLVED: To provide a simple washing tub for care that is used to allow mainly a bedridden invalid to have a shower bath in an unchanged lying position on a bed. SOLUTION: A substantially square waterproof sheet body has the form of a substantial square having the substantially same size as a bed top. Each peripheral end of the sheet body consists of a frame part in the form of a hollow looped bag. With the frame parts in a raised position, the internal faces t opposed ends of the frame parts are bonded together to form a cube, and separate cores are removably inserted in the frame parts.
