Conclusion: Simple distinctions between improved and unimproved sanitation facilities tend to misrepresent the variability
observed among households sharing sanitation facilities. Our results suggest that private improved sanitation is consistently
preferred over any other sanitation option. An increased number of users appeared to negatively affect toilet cleanliness,
and lower levels of cleanliness were associated with lower levels of satisfaction. However, when sanitation facilities were
clean and shared by a limited number of households, users of shared facilities often reported feeling both satisfied and safe.
