Bidet shower

[2][3] In predominantly Catholic countries,[4] the Muslim world,[5] the Eastern Orthodox[6] South Asia, and some Protestant countries such as Finland, water is usually used for anal cleansing, using a jet (bidet shower, bidet) or vessel, and in some places a person's hand (in some places only the left hand) is used.

[7] The shower is an alternative for the traditional sources of water for this action, such as the bidet, copper pot or bucket and mug, being more hygienic and compact.

This includes Algeria, Bangladesh, Brazil, Cambodia, Egypt, India, Indonesia, Iran, Iraq, Malaysia, Maldives, Nepal, Pakistan, Philippines, Singapore, Saudi Arabia, Sri Lanka, Thailand, United Arab Emirates, Vietnam etc.

It is so ubiquitous that Thai parliamentarians were outraged upon learning that the toilets in their new parliament building were not equipped with Muslim showers.

The use of water in many Christian countries is due in part to the biblical toilet etiquette which encourages washing after all instances of defecation.
