Europe
One thing about Europe is there is such a huge variety of toilets. Toilets in Europe are somtimes set up as street decoration. Public toilets are also set up as compensation for advertising permits.
Many toilets in Europe today use the 2-flush system, such as in the diagram to the left. Flushing down would be for urine or liquids, which uses less water saving you money and water. Flushing up would be for stool or thicket waste to efficiently empty your toilet of waste.
