Handicapped toilets. Gotta love 'em.
Not all toilets are the same - more to the point, not all height requirements for handicapped toilets are the same. Dependent upon where you live, the height requirements for handicapped toilets varies.
I have noticed a lowering of standards (pun intended) for handicapped toilets in the newer buildings that I've frequented. After my hip replacements, when it was crucial that I didn't exceed the ninety-degree rule, I had a back-up plan, when I went out. Fortunately, I never had to use it. Too much information?!
What are the height requirements for handicapped toilets where you live?
