nope. they're the same tile set as the floor, a mottled grey (guessing) vinyl application. they've been waxed. the walls are strangely the same tiles as the floor, but with a footer and rail tile. everything has been waxed and buffed to level 27.

Oh, that's what it is. I think the lower wall sections are covered in plastic to protect them from being damaged by hospital beds or something like that.
