So what I'm looking for, I suppose, is something that's easy to wipe
clean, that will stand up to the kind of beating it's going to get and
repeated washing. ...

I built a clean room, which had to be washed down with bleach and
disinfectant on a regular basis, using skinned foamed PVC sheet to line
walls and ceiling. The industrial grade vinyl floor has started to wear, but
the walls are just as good as when they went up in 1990.
