Abstract
This chapter considers how the study of Roman baths and bathing customs is related to public latrines and their use. First, public latrines have become more common in baths and within urban settings. The increasing frequency of toilet services in cities was becoming a part of Roman cultural identity, much like baths. Second, the existence of baths and public latrines in Roman cities is very to be related to the social custom of communal living for an expanding urban population. Third, simultaneous improvements in Roman building technology also have contributed to the building of baths and latrines in cities. Developments particularly related to the production of more durable concrete allowed for increasingly larger, more elaborately designed, and more lasting structures. The final and perhaps most important reason for explaining the spread of baths and latrines relates to the influences of trade and travel, since these two are most often the mechanisms for technology transfers.
