A bidet shower, bidet spray, bidet sprayer or health faucet (sometimes colloquially, a "bum gun") is a hand-held triggered nozzle, similar to that on a sink sprayer, that delivers a spray of water to assist in cleansing the user's anus and genitals after defecation and urination. It is usually placed in a small holder attached to the wall, on the right hand side of a flush toilet and connected via a short hose to the plumbing and faucet that feeds the flush cistern.
Its use is very common in parts of Asia where water is considered essential for cleansing. This includes India, Indonesia, Malaysia, Pakistan, Sri Lanka, Thailand and Vietnam . In Europe it is used in Finland and some Romance-speaking countries. It's very common in Brazil where traditional bidets are being replaced by it over the last decades. It is also common in Arab countries and some parts of the Muslim world. In Asia it is commonly installed with western toilet installations. In Thailand it is common on both Western and squat toilet installations. The “bidet shower” is similar in intent (if not method of use) to the Japanese washlet-style toilet seats.
The health faucet is a convenient source of water for people who prefer using water to other methods of anal cleansing. The Bidet shower is a relatively modern replacement for the traditional sources of water for this action, such as the bidet, a copper pot, a bucket and mug, etc., being more hygienic and compact.
- There is no contact between the spray of water and the used water drainage, unlike in the operation of a bidet (although newer designs of bidets avoid contact between spray and drainage).
- The device is handled only during the cleansing operation and is placed in a holder located off the floor for storage between uses.
