There are two basic types of toilet systems: on the one type, a person sits, the other type requires a squatting position. WC Health is designed in a way that it provides both systems and thus best serves the human physiology. In a sitting position the angle of the feet to the toilet is 90 degrees, whereas in a squatting position the angle is 40 to 60 degrees. This second position leads to contraction of the abdominal muscles and thus to a very good evacuation, which promotes good health and prevents illnesses.
