The utility model relates to a bathtub which can be folded and distracted; a bathtub frame consists of two big supporting frames in II-shapes, four box covers, four small supporting frames in trapezoid-shapes, four boosters, four steering blocks, four block cups and two hinges; a bathtub tire made of rubber is attached with a drain pipe consisting of a water plug, a water pipe and a three-through connector; the bathtub is fixed on the bathtub frame through a screw. When the utility model is in use and if the big supporting frames in II-shapes are distracted and the turning angle of the small supporting frames in trapezoid-shapes exceeds 45 DEG, the bathtub frame is distracted automatically; if the big supporting frames in II-shapes on the bathtub frame is folded and the turning angle of the small supporting frames in trapezoid-shapes is less than 45 DEG, the bathtub frame is folded automatically.
