Bidet is not a popular item in Korea though it is very popular in Europe and America. So it would be desirable to describe it at first. It is a form of lavatory providing facilities for bathing those free regions not accessible for washing when a person is fully dressed. It is one of the most significant advances toward personal hygiene since the introduction of indoor plumbing. The bidet is a device for rinsing with a built-in spray. The bidet can be easily attached to the basin and it is equipped with hot and cold water supply valves.
The bidet should be considered a hygienic necessity rather than a luxury. Daily use of this device should become a part of the family routine, as conventional as washing hands and face. After a bowel movement it is impossibly to cleanse the anus with dry paper. Toilet tissue has been perfumed, tinted and made antiseptic, but nevertheless it is still paper. Babes always have their bottoms washed, but when they are on the stage of self-reliant childhood, they are permitted to revert to medieval custom of wiping with dry paper. The prophylactic advantages of bidet can be found as below.
