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.
This clip could be used as a link to hygiene topics. It can lead into discussion of the facilities such as running water or heating that the Romans had. How do these compare to what we have today? The clip raises the issue of reusing water, which can link to green lessons.
