The Vinaya Pitaka, a rulebook for Buddhist monks, describes proper toilet use in detail. As just a small sampling, proper Buddhist monks should defecate in the toilet in the order of arrival rather than that of seniority; should cough loudly when arriving at the toilet (and anyone already there should cough in response); should not chew tooth-cleaning wood while defecating, should not grunt while defecating, and should not wipe himself with a rough stick.
The Temple of the Six Banyan Trees is one of the few Buddhist temples left standing in Guangzhou, People's Republic of China, where any religion other than worship of Communist leaders is strictly regulated and mostly prohibited.
Let's have a look at their toilets:
Notice the floor covered with small tiles, and the raised footpads. Those are specially designed ceramic blocks.
You can buy these ceramic blocks at building supply shops. I suppose ceramic squatter footpad blocks might make for a less inconvenient souvenir than an entire squat toilet...
Also notice the long hose for cleaning yourself. The floor in the stall drains into the toilet. Of course, with a hose running briskly not all of the water is going to drain into the toilet. There's a shallow channel along the row of stall doors that will catch most of the overflow.
As collectivist Chinese toilets go, this one provides a much higher degree of privacy than usual. See the toilets at the Tomb of the Martyrs of the Guangzhou Commune W.C. for more typically communal Chinese toilets.
This is their sign pointing the way.
The way to the toilet, not the way to enlightenment.
