It depends on the size and preference of the user(s), but wall hung toilets should be installed anywhere between 15 and 19 inches up from the floor.
The standard height for a wall hung toilet to be fitted off the ground is generally considered to be 15 inches. But users with special requirements, or elderly people, might prefer their home toilets to be positioned slightly higher, making them easier to sit on.
