I realised something recently. The handle bars and paraphernalia in disabled toilets are more likely to have originated from another need. It was through a mixture of a bit of embarrassment, and changing PC tides that the needs of the constipated and the inverse were (rightly) subverted for the needs of those with disabilities.
That’s right! The different handle bars in disabled toilets were originally designed to help when your regulars are not suitably regular.
