These were the only public toilets in Ephesus and it is said that they were for man. Toilets are very well protected. There should be another public toilet for women in Ephesus which hasn't been found yet. There were 44 holes on the three sides of Ephesus.
There was a fresh water channel just in front of the holes. There were mosaic paved floors. There was an open-air pool in the center. People had to pay entrance fees to the public toilets.
