Men's urinals can either be mounted on a wall, or can extend all the way to the floor.
According to this page, floor mounted urinals are less desirable because:
- These units are tall (36" - 40") and have the bowl and drain on the floor.
- Harder for men to use than standard height wall mount.
- Spots and splashes on the floor are common place.
Along these lines I have also often heard the charge they are "less sanitary"
In my experience, however, it seems like there is always a puddle beneath the wall mounted unit. Along these lines, a floor mounted unit should be more sanitary, because more of the drips that would otherwise go on the floor would still end up within the porcelain.
So, with this argument in mind, why is it so rare in the United States to see a floor mounted unit, and why are wall-mounted units considered to be more sanitary?
