The global pandemic, known as COVID-19, has infected over 200 million people, and has led to over 4 million confirmed deaths as of September 2021. This is potentially due to cross infections, which occurs virtually anywhere at any time. As such, public areas, such as public toilets, are some of the major contributors to the high infection rates. This short paper studies the major pain points of 23 participants who use public toilet aging from 18 to 53 during the COVID-19 pandemic in Hong Kong, and state their concerns on the issue, such as physical contact and mental stability. Solutions for public toilet issues will be discussed in the new designed models, aiming to help cope with, and or resolute, the pain points.
