Floor Mounted Toilets
Modern days floor mounted units are known as couple closet WBC. These couple closet come along with the flush tank. Both the closet and the tank are made of ceramic materials. An S-trap drainage pipe that extends from bottom of the bowl and through the floor is fitted for floor mounted units.
Wall mounted Toilets
Wall mounted units are fitted to the wall unlike floor mounted units. These are free from floor, fitted say about 12” above the floor level. The outlet pipe for Wall mounted toilets are fitted from bottom but in P trap style which goes to the wall (unlike floor mounted). The flush tank for wall mounted units gets concealed in the wall.
Now days there are stylised flush tanks that come with two flush buttons. One of the buttons when pressed will flush 6liters of water and the other one will flush 9 litres of water. According to the requirement, these two flush buttons are used. Before the seat covers (for WBC’s) were harsh. They used to bang if left for closing. But now the seat covers are soft closing i.e. it will slowly and soft close when released. Initially Toilets had different vent pipe (ventilation pipe) fitted. But then the bad smell returned from drainage pipe. This made the room stink even after flushing. But this problem was soon overcome. Now if you see WBC’s there are no separate vent pipes fitted. They are manufactured in such a way that a water level is achieved even after flushing. This helps get rid of the bad smell.

Wall mounted units rather need a thicker wall to support the tank and the unit, which many buildings are not well prepared with. Here remodelling is often required which increase your cost.
Wall mounted offer considerably more space then floor mounted units. This is because the tank gets concealed. The bathroom/washroom also looks bigger with wall mounted units. Also the wall mounted units can be fitted as per your requirement which does not work for floor mounted units as they come with standard sizes.
Wall mounted units also can be better cleaned then the floor mounted. This is because the floor below the units is free which can be mopped easily.
