When out on patrol, Roman soldiers would just go to the toilet wherever they were. Back at the fort, they shared communal toilet spaces, such as can be found at Hadrian's Wall. The toilets had their own plumbing and sewers, sometimes using water from bath houses to flush them. The Romans did not have toilet paper. Instead they used a sponge on a stick to clean themselves.
Students could be asked to recall the description of a Roman toilet, they could then discuss in what ways these are different or similar to toilets today. Students could also discuss whether they think Roman toilets were hygienic. What could make them more hygienic? Students could design a hygiene poster for a Roman toilet which might encourage them to wash their sponge after every use, or make sure they always wipe around the seat.
