Shared sanitation has immensely contributed to sanitation access in urban areas, but is at best considered a "limited" solution due to the lack of quality standards within Sustainable Development Goal #6.
This policy brief presents the main results of the QUISS project (Quality Indicators of Shared Sanitation), a three-country com-parative mixed-methods study that identified the key criteria of what constitutes "accept-able quality" shared toilets in urban low-income contexts and provides recommen-dations for strengthening the acceptability, functionality and sustainability of shared sanitation facilities.
