Handwashing is a critical practice that is promoted to protect public health, especially during outbreaks of infectious diseases such as COVID-19. Handwashing stations are used both in emergencies and in other contexts to provide locations for people to wash hands with soap. In refugee camps and internal displacement centres, units for handwashing should be installed both at households and next to latrines and in communal areas, such as in markets, schools, and health centres. This document lists a range of options for handwashing stations. This information is especially geared towards the need for communal handwashing, including in refugee/IDP settings. However, some handwashing designs can be used in households and/or adapted for use in other settings.
