This manual presents three adaptable designs for a trench latrine block, raised latrine block and bathing block. Development of these solutions followed a user-centred approach to understand the main barriers, challenges and opportunities that WASH, and shelter practitioners perceive, when designing and implementing WASH facilities that enable women and girls to manage their menstruation. The guidance and tools developed were be based directly on this learning and recommendations from end users (WASH & shelter practitioners). The solutions presented in this manual are intended to be adaptable for a wide range of contexts, and therefore the design information is accompanied by guidance on how to assess the needs of the target community and local site constraints.
