The problem is not in getting foot baths or special bathroom, the problem is what is going to come after! In Islam, he can do his prayers (even the ones he missed) when he gets home or his mosque later. But NO! Why would he do that if he can ask for it? Even some schools in the middle east don't have this kind of bathrooms.
FYI: Jews need to wash up as well, but you didn't see any Jew asking for this!
