In many parts of Asia, people traditionally use the toilet in a squatting position. This applies to defecation and urination by males and females. Therefore, homes and public washrooms have squat toilets, with the toilet bowl installed in the floor. This has the advantages of not needing an additional toilet seat and also being more convenient for cultures where people use water to wash their genitals instead of toilet paper. However, Western-style toilets that are mounted at sitting height and have a plastic seat have become popular as well. Many public washrooms have both squatting and sitting toilets.
