Gw mau tau Sejarah dari Bilik air. Jelasin dalam bahasa melayu

Sungguhpun ia bukannya untuk kebersihan, rekod pertama bagi penggunaan bilik air bermula sejak 3000 B.C. Pada masa ini air mempunyai nilai keugamaan yang penting, dilihat sebagai unsur penyucian bagi ke dua badan dan jiwa, dan dengan itu adalah biasa bagi seseorang diperlukan bagi menyucikan diri mereka semelum memasuki tampat suci. Tempan mandi direkodkan sebagai sebahagian kampung atau bandar sepanjang tempoh ini, dengan pembahagian antara mandian wap di Eropah dan Amerika dan mandian sejuk di Asia. Mandian awam didirikan di kawasan berasingan dengan ruang tinggal di kampung, dengan tujuan menghalang semangat jahat memasuki tempat tinggal awam.

According to Teresi et al. (2002):

The third millennium B.C. was the "Age of Cleanliness." Toilets and sewers were invented in several parts of the world, and Mohenjo-Daro circa 2800 B.C. had some of the most advanced, with lavatories built into the outer walls of houses. These were "Western-style" toilets made from bricks with wooden seats on top. They had vertical chutes, through which waste fell into street drains or cesspits. Sir Mortimer Wheeler, the director general of archaeology in India from 1944 to 1948, wrote, "The high quality of the sanitary arrangements could well be envied in many parts of the world today." Nearly all of the hundreds of houses excavated had their own bathing rooms. Generally located on the ground floor, the bath was made of brick, sometimes with a surrounding curb to sit on. The water drained away through a hole in the floor, down chutes or pottery pipes in the walls, into the municipal drainage system. Even the fastidious Egyptians rarely had special bathrooms.
