How Genshins poop in each region:
>In Mondstadt, people use chamber pots and cesspits, while Mondstadt city walls had "garderobes"—projecting rooms that emptied waste into Starfell lake. Public latrines were also common, often built over rivers or streets, and residents of cities disposed of chamber pots in various ways, including into street gutters or by dumping them out windows

>In Liyue, people pooped using various methods, including outhouses over pigpens, which was an efficient way to turn waste into fertilizer, or using chamber pots that were emptied into cesspools or collected for farming.

>In Inazuma, people used pits and toilets were built over running streams or rivers, allowing waste to be washed away, which is considered a primitive form of a flush toilet. For cleaning, they used tools like wooden sticks called kusobera or chūgi, as well as water, and collected the waste for use as valuable fertilizer.

>In Sumeru, people openly defecate in fields, bushes, or along Sumpter Beast trails. Although the Akademiya has built millions of new toilets to combat the problem, open defecation remains a challenge, particularly in rural areas, due to a combination of factors.

>In Fontaine, people primarily use standard seated toilets. However, poorer areas such as Poisson and the Fleuve Cendre may still have "squat toilets," also called toilettes à la turque. These have a hole in the floor where users squat over it.

>People in Natlan poop in a variety of ways depending on sanitation access, including using traditional pit latrines, squat toilets, modern toilets, and by practicing open defecation or using "flying toilets" (plastic bags) in tribes with poor infrastructure. Methods of cleaning vary from using leaves or paper to using a bucket of water to wash, though the Children of Echoes use hi-tech toilets with bidets and automated toilet paper dispensers due to the great inventor Xilonen's advances.
