The toilet shown to the left is just stone shaped in the form of a seat with a hole in it. Toilets that date back to the 18th century BC were usually similiar to this. They look like they are meant for sitting, but were probably used as squat toilets and elevated to help with plumbing.
Some of these civilizations that used toilets made out of stone even had drainage systems. These drainage systems led to a main section where all of the waste was stored.

The Roman army did not have toilet paper. So instead, they used a sponge soaked in water that was on the end of a stick.
