Yea, that is true. I remember having 1 in Queens, wasn't a bathtub but between the toilet and the wall. Slipped while using their walker and that was it, STUCK, took R4, 2 truck Co's and several ESU Units and after removing part of the wall, the toilet and medicine cabinet got her out. Did fracture a small bone in the pelvic region. That was around 1998 in Jamaica. Was working 50V.
