This policy brief presents the main results of a three-country study on Quality Indicators of Shared Sanitation (QUISS). QUISS assessed when shared sanitation is acceptable and what is needed to establish minimal acceptability requirements. Qualitative and quantitative data were collected in Ghana, Kenya and Bangladesh in 2019. This brief highlights the research findings for Kenya and provides recommendations for strengthening the acceptability, functionality and sustainability of Kenya’s shared sanitation facilities in low-income urban settlements.
