I only know of random examples of toilets, and mainly stuff about waste disposal. there isn't a lot of historical records on waste disposal in a lot of civilizations, probably because it was either seen as uninteresting to write about or unpleasant.

the aztec and incas both utilized aqueduct systems that pushed human waste to a centralized point, where it could then be moved and used as fertilizer. the city of tenochtitlan had a particularly efficient system for this, where they could easily move human waste collected in deposits from moving water to floating farm works via canoe. they with the incas arguably had one of the most impressive pre-modern waste disposal systems, one of the few things they did better than many other historical emergent civilizations.

edo japan had trenches beneath boards to stand on while squatting, or containers underneath more luxurious squat toilets. people as their form of producing income would have collection routes, where they would collect as much human waste as they could and sell it as manure. human shit manure was actually a quite valuable resource around the city.

they were among the first to use toilets connected to sewage systems in civilization, ironically.
