20.59

又毘尼母經云。諸比丘住處房前閒處。小便污地臭氣皆不可行。佛聞之告諸比丘。從今已去。不聽諸比丘僧伽藍處處小行。當聚一屏猥處。若瓦瓶若木筒。埋地中小行已。以物蓋頭莫令有臭氣。若上廁去時。應先取籌草至戶前。三彈指作聲。若人非人令得覺知。若無籌不得壁上拭。不得廁板梁杙上拭。不得用石。不得青草。土塊軟木皮軟葉奇木。皆不得用。所應用者。木竹葦作籌。度量法極長者一搩手。短者四指。已用者不得振令污淨者。不得著淨籌中。是名上廁用籌法。上廁有二處。一者起止處。二者用水處。用水處坐起褰衣。一切如起止處無異。廁戶前著淨瓶水。復應著一小瓶。若自有瓶者。當自用。若無瓶者。用廁邊小瓶。不得直用僧大瓶水令污。是名上廁用水法。

Also, the Vinayamātṛkā states: “In front of the bhikṣus' living rooms and in open spaces, urine soiled the ground and the foul stench made it impossible to walk. When the Buddha heard of this, he told the bhikṣus: ‘From this day forward, bhikṣus are not permitted to urinate in various places throughout the saṅghārāma. They should gather it in a secluded, screened place, using either an earthenware jar or a wooden bucket buried in the ground. After urinating, cover the top with an object so as not to let out a foul stench. When going to the privy, one should first take a scraper stick and go before the door, snapping the fingers three times to make a sound, so that humans or non-humans are made aware. If there is no scraper stick, one must not wipe on the wall, nor on the privy boards, beams, or pegs. One must not use stones, nor fresh grass, clods of earth, soft tree bark, soft leaves, or unusual wood—none of these may be used. What should be used: make scrapers from wood, bamboo, or reeds. The rule of measurement: the longest is one span; the short is four finger-breadths. Those already used must not be shaken so as to soil clean ones, nor placed among the clean scrapers. This is called the rule for using scrapers when going to the privy. There are two places at the privy: the first is the place for relieving oneself; the second is the place for using water. At the place for using water, sitting, standing, and lifting robes are all just as at the place for relieving oneself without difference. Before the privy door, place a pure pitcher of water, and one should also place a small pitcher. If one has one's own pitcher, one should use it oneself. If one has no pitcher, use the small pitcher by the privy; one must not directly use water from the Saṅgha's large pitcher so as to soil it. This is called the rule for using water when going to the privy.’”
