In both developed and developing countries, many of the organizations active in water, sanitation and hygiene (WASH) provision have asserted that separate toilets for boys and girls at school are very important to make girls feel comfortable and safe using the sanitation facilities at schools. For example, in 2018, UNESCO stated that single-sex toilets are needed to overcome girls' barriers to education. This concern could potentially apply to boys as well, especially if open urinals are maintained. As an alternative, some argue that unisex school toilets could be provided at schools in addition to facilities that are separated by gender (which is often the case already in the case of toilets for people with disabilities).
