The World Toilet Organization is an organization dedicated to issues involving toilets and sanitation. It is based in Singapore and, as of 2004, includes toilet associations from 17 countries around the world, from Russia to the United States to Australia to Japan [1] (http://www.worldtoilet.org/abtus/abtus.htm).
Every year, the World Toilet Organization sponsors the World Toilet Summit. This has been held in various places around the world:
The World Toilet Organization promotes the celebration of World Toilet Day on November 19 of every year. [2] (http://newpaper.asia1.com.sg/top/story/0,4136,41618,00.html)[3] (http://www.cwwa.ca/internationalwaterdays_e.asp)[4] (http://www.abc.net.au/greatsouthern/stories/s992785.htm)
The most common choice in the Western world is toilet paper, sometimes used in conjunction with the bidet; see toilet paper for a discussion of the many alternatives used through history and in different cultures.
Separation by sex is characteristic of public toilets to the extent that pictograms of a man or a woman are used to indicate where the respective toilets are.
Sex-separated public toilets are often difficult to negotiate for transgendered or androgynous people, who are often subject to embarrassment, harassment, or even assault or arrest by others offended by the presence of a person they interpret as being of the other gender (whether due to their outward presentation or their genital status).
