The bathtub 1 comprises a lateral wall 2 whose contour, in plan view, has a curved zone 3 whose concavity faces inwards and which has a mean centre of curvature C. In the region 5 which is opposite, relative to the mean centre of curvature C, the said curved zone, the lateral wall 2 has a surface 6 whose points 9, 7, in a horizontal cross-section, are located at increasing distances, for a specific direction of rotation, from the opposite points 10, 8 of the curved zone 3 which are located in the same horizontal cross-section, a point of the opposite region and the opposite point of the curved zone being substantially in line with the mean centre of curvature C. <IMAGE>
