Adding to the stench of Roman life, my close examination of ancient plumbing found that many downpipes from house toilets on upper floors would have suffered serious leakage inside the walls as well as oozing onto the outside of the walls too. The fittings of these terracotta downpipes loosened over time, and their contents would have caused stink everywhere.
I was able to identify at least 15 upper-story toilets at Pompeii and others at Herculaneum and elsewhere. In some cases, I obtained proof through scientific testing for urine and/or excrement that the spillage was indeed human waste from these pipes.
Public toilets held their own hazards
Even public latrines – multi-seater toilets that were almost always connected to the main sewer lines of a city – posed serious threats to users. Don’t be fooled by the clean white marble and open-air sunniness of the reconstructed ruins we can see today; most Roman public toilets were dark, dank and dirty, and often situated in small spaces. Those who could “hold it” long enough to return to their own houses with their own cesspit toilets certainly would have done so.
A humorous reconstruction of the communal nature of a Roman public latrine. Note the sponge-on-stick tools.Gemma C M Jansen
One public toilet at Ostia, with its revolving doors for access and fountain basin for cleaning up, could handle more than 20 clients at a time. I have found no evidence that Romans had to pay to use public toilets, and we really don’t know who managed or cleaned them, apart from the possibility of public slaves. To our modern eyes there was almost a complete lack of privacy in such facilities; but bear in mind that Roman men would have been wearing tunics or togas, which would have provided more screening than a modern man would enjoy with pants that have to be pulled down. Perhaps a bigger problem for today’s standards of cleanliness: the Roman version of toilet paper in many cases was a communal sponge on a stick.
Even worse, these public latrines were notorious for terrifying customers when flames exploded from their seat openings. These were caused by gas explosions of hydrogen sulphide (H2S) and methane (CH4) that were rank as well as frightening. Customers also had to worry about rats and other small vermin threatening to bite their bottoms. And then there was the perceived threat of demons that the Romans believed inhabited these black holes leading to the mysterious underbelly of the city.
