又僧祇律云。若欲浴時使園民等掃灑。令淨辦具薪炭溫暖得所。乃打揵稚應知入浴。各以腰帶繫衣作識安衣架上。入時不得掉兩臂而入。一手遮前而入。若欲與師揩者。當先白已無罪。不得一時舉兩手。當先令揩一臂一手覆前竟。次揩一臂一手及餘內外已。閉戶而坐令身汗出。籌量用水不得多用。若池水洗自恣無罪。不聽露地裸形而浴。若水齊腰腋得用無罪。若坐水中至臍亦得。出已取己衣著正理而去。

Furthermore, the Mahāsāṃghika-vinaya says: When one wishes to bathe, one should have the monastery servants sweep and sprinkle [water], making it clean, and prepare firewood and charcoal so that the warmth is suitable; only then should the gaṇḍī be struck so that they know to enter the bath. Each person uses their waist-belt to tie up their robes as a mark and places them on the clothes rack. When entering, one must not swing both arms to enter, but should enter covering the front with one hand. If one wishes to scrub down a master, one must first announce it, and then there is no offense. One must not raise both hands at the same time; one should first have him scrub one arm with one hand covering the front, and next scrub the other arm, the hands, and the rest of the body inside and out. Then, close the door and sit down to let the body sweat. One must measure the water used and not use too much. If bathing in a pool, one may do as one pleases without offense. Bathing naked in the open ground is not permitted. If the water comes up to the waist or armpits, it is permissible without offense. Sitting in the water up to the navel is also permissible. After coming out, take one's own robes, put them on properly, and leave.
