Famous Architect Recommended Natural Squatting
If you visit Fallingwater, the famous home designed by Frank Lloyd Wright (1867-1959), you can see very artistically-designed toilets only 12 (30.5 cm) to 14 inches (35.5 cm) high.
They were made that way not because he and his wife were short people. But it is because of his serious concern that squatting was the only healthy way to defecate. He cited different locations and cultures in the world who also believe this and practise it.
As you might expect, the world's best architect added a few features to his own structures, such as a tiled floor and porcelain "squatting bowl" ( for lack of a better term). He made concessions for his guests, however, and provided a standard toilet in their bathroom.
