Questionnaire and Observation Study on the Usage Patterns of Sanitary Fixtures in the Toilet of High School Building

In designing a toilet, the minimum number of sanitary fixtures is determined by the purpose and level ofbuilding, the number of using people, and etc. Currently, specific regulations for the number of sanitary fixtures (the numberof water closets, urinals) in the toilets are not available but the law regulates only the occupied area of the water closetsand urinals according to the size of toilets. An effective design cannot be achieved without clear standards indesigning the number of sanitary fixtures. Thus, the standards for the number of sanitary fixtures should be established todesign the toilets. This study used the questionnaire and observation study for using the male and female toilets in thehigh school building to analyze the average number of toilet usage, the time of usage, the time zone of excessive usage,and etc. And, furthermore, it provided the basic data to determine the number of sanitary fixtures(number of water closets,urinals).
