To provide a cover for bathing to prevent warm water stored in a portable bathing bag of a bathing apparatus from spilling out, and to prevent a large pressure on the bathing bag.

The cover for bathing includes a lower cover 2, an upper cover, and a frame to set up and support the upper cover. The lower cover 2 is obtained by forming continuous standing walls on both sides and front and rear parts of a waterproof bottom sheet material made of a synthetic resin or rubber, etc., having a width to allow a person to lie on his/her back and an appropriately fixed length to accommodate the whole body. The upper cover is made of a water barrier and flexible sheet and has a three-dimensional shape such as a semicylindrical, barrel, or polygonal shape with a width corresponding to that of the lower cover and an appropriately fixed length to accommodate a part up to the shoulders of the person, and includes a plurality of insertion holes arranged at desired positions so as to insert hands into the inside; and stop walls arranged at the front and rear ends. The frame includes two curved supporting materials whose lower ends are integrally connected with a connecting material and a holding material integrally provided at a part slightly lower than upper ends of the supporting materials.
