I was in hospital Monday and noticed the toilet was floor-mount, a lot like a home toilet. I remembered the last time I was in a (different) hospital, that it also had a floor-mount toilet. Most big buildings have wall-mount toilets, which must require some sturdy mount. What's the point of a wall-mount toilet? Easier to clean underneath? If they'd rather not run plumbing under the floor, why not a rear-discharge floor-mount toilet?

I think wall mount toilets will be more efficient in cleaning, especially in rooms that are basically wet rooms with the lav + toilet both wall mount, with a curb-less shower. In a hospital setting where you may have patients struggling to use the facility a space where it will not impede wheelchairs, rolling IV pedestals, walkers etc...and can be completely hosed down when needed with no obstructions to clean around.

On the other hand, floor mount toilets have better stability, because there is a lot of downward and lateral forces when someone transfer say from a wheelchair to a toilet, and a wall mount is not as good in these scenerios, or with oversized users. Wall mount toilets also use the wall carrier and doesn't seal with a traditional wax ring so it requires some special framing I suspect so the toilet connection is stable in the wall, I haven't seen how a wall mount toilet is roughed and how it's connected to the framing, I am thinking like in a hospital say 10-12 stories the interior partitions are framed with steel studs that I can deform with my bare hands, how they do a wall mount rough in that is strong and stable to receive a toilet that may have such force of a 250# person transferred off a wheelchair.
