Public toilets, a worldwide problem, are also a problem that I face every time I go out in the United States in five years. I met the same problems in New York, Boston, Washington, Miami, Los Angeles, and San Francisco. I did not know where to go to the toilet, and the toilet was not clean. This project is more for my personal life experience that prompted me to choose the toilet as my topic. The choice of Soho is because this is where I go most often in New York and where I have recently encountered toilet problems. I hope to make a meaningful contribution to the toilet problem in Soho area through my investigation, study, research and design. This booklet covers all my research studies and design responses.
