By buying this bathtub, above this mark, we thought receive a 100% compliant. However, the tub is plastic (molded), three circles probably included in the manufacturing process, are at the bottom of the bathtub. The edges of the circles hardly exceed a few millimeters but enough to scratch the baby feet which obviously moves in his bath. My husband had to sand the circles to make it perfectly smooth and prevent the return of the latter since we are convinced that this is a problem that appears from the molding and manufacturing.
