Abstract: A foldable bathtub is provided. The foldable bathtub includes a bathtub body that is formed by a soft packaging layer that is supported by a shaping frame and a supporting frame g through a connector, the shaping frame and the supporting frame are composed of different styles of fixed joints and foldable joints. There are multiple connections between the shaping frame and the supporting frame that can be rotated or folded or rotated and folded at the same time. A user can decompose the bathtub body through reasonable and limited steps, which is convenient for the user to store. When in use, the decomposition steps are only needed to reverse to form the bathtub body, which has a simple folding process.
