Unless the elevator ride is exceptionally long, I don't understand why restrooms would be necessary. Likewise, I see no advantage to having restrooms move up and down, unless it is a way so that not as many restrooms need to be built. Maybe that's it! If you need a restroom, push the button and one will come up or down (from another floor) if it isn't in use.
I'm still not clear as to how the water pipes are incorporated into an elevator, unless they are chemical toilets and need to be emptied periodically. This would likely be done on the lower level.
