Urination is the release of urine from the bladder to the outside of the body. Urine is released through the urethra and exits the penis or vulva through the urinary meatus in placental mammals, but is released through the cloaca in other vertebrates. It is the urinary system's form of excretion. It is also known medically as micturition, voiding, uresis, or, rarely, emiction, and known colloquially by various names including peeing, weeing, pissing, and euphemistically number one. The process of urination is under voluntary control in healthy humans and other animals, but may occur as a reflex in infants, some elderly individuals, and those with neurological injury. It is normal for adult humans to urinate up to seven times during the day.
A urinal is a sanitary plumbing fixture similar to a toilet, but for urination only. Urinals are often provided in men's public restrooms in Western countries. They are usually used in a standing position. Urinals can be equipped with manual flushing, automatic flushing, or without flushing, as is the case for waterless urinals. They can be arranged as single sanitary fixtures, or in a trough design without privacy walls.
Toilets in Japan are sometimes designed more elaborately than toilets commonly seen in other developed nations. European toilets occasionally have a separate bidet whilst Japan combines an electronic bidet with the toilet. The current state of the art for Western-style toilets in Japan is the bidet toilet, which as of March 2016 is installed in 81% of Japanese households. In Japan, these bidets are commonly called washlets, a brand name of Toto Ltd., and they may include many advanced features rarely seen outside of Asia. The basic feature set commonly found on washlets consists of anal hygiene, bidet washing, seat warming, and deodorization.

A chemical toilet collects human excreta in a holding tank and uses chemicals to minimize odors. They do not require a connection to a water supply and are used in a wide variety of situations. These toilets are usually, but not always, self-contained and movable. A chemical toilet is structured around a relatively small tank, which requires frequent emptying. It is not connected to a hole in the ground, nor to a septic tank, nor is it plumbed into a municipal system leading to a sewage treatment plant. When the tank is emptied, the contents are usually pumped into a sanitary sewer or directly to a treatment plant.
A bedpan or bed pan is a device used as a receptacle for the urine and/or feces of a person who is confined to a bed and therefore not able to use a toilet or chamber pot.
Potty parity is equal or equitable provision of public toilet facilities for females and males within a public space. Parity can be defined by equal floorspace or by number of fixtures within the washrooms, sometimes adjusted for the longer average time taken and more frequent visits to the washroom for females, among other factors.
Unisex public toilets are public toilets that are not separated by sex or gender.
A urine collection device or UCD is a device that allows the collection of urine for analysis or for purposes of simple elimination. UCDs of the latter type are sometimes called piddle packs.
A female urinal is a urinal designed for the female anatomy to allow for ease of use by women and girls. Different models enable urination in standing, semi-squatting, or squatting postures, but usually without direct bodily contact with the toilet. Sitting models also exist, and are designed for body contact with the urinal.
An aircraft lavatory or plane toilet is a small unisex room on an aircraft with a toilet and sink. They are commonplace on passenger flights except some short-haul flights. Aircraft toilets were historically chemical toilets, but many now use a vacuum flush system instead.
A toilet is a piece of sanitary hardware that collects human waste, and sometimes toilet paper, usually for disposal. Flush toilets use water, while dry or non-flush toilets do not. They can be designed for a sitting position popular in Europe and North America with a toilet seat, with additional considerations for those with disabilities, or for a squatting posture more popular in Asia, known as a squat toilet. In urban areas, flush toilets are usually connected to a sewer system; in isolated areas, to a septic tank. The waste is known as blackwater and the combined effluent, including other sources, is sewage. Dry toilets are connected to a pit, removable container, composting chamber, or other storage and treatment device, including urine diversion with a urine-diverting toilet.
In health care, toileting is the act of assisting a dependent patient with their elimination needs.
Urine flow rate or urinary flow rate is the volumetric flow rate of urine during urination. It is a measure of the quantity of urine excreted in a specified period of time. It is measured with uroflowmetry, a type of flow measurement.
An interactive urinal is a device that allows users to play video games or control interactive displays while urinating. Several designs have been produced to date, usually comprising a urinal fitted with a pressure sensor to measure the strength and position of the urine flow and an LCD screen mounted above the urinal to provide animated graphics.
A pissoir is a French invention, common in Europe, that provides a urinal in public space with a lightweight structure. The availability of pissoirs aims to reduce urination onto buildings, sidewalks, or streets. They can be freestanding and without screening, with partial screening, or fully enclosed.
Pollee is a mobile female urinal, designed by Nuala Collins, Christian Pagh and Sara Nanna and produced by the Danish design bureau UIWE. It is specifically designed to be used at public events such as concerts or music festivals.
The Pee Pocket is a single-use urinary device that allows a person to stand while urinating, in situations where they could not normally do so.
madamePee is a mobile female urinal, without contact and without water supply. It is designed to be used at public events such as concerts or music festivals, but also in more durable situations such as construction sites, public gardens, etc.
A urine deflector is a device for deflecting the stream of urine during urination. These may be part of a chamber pot, latrine or toilet intended for the purpose, or they may be deterrents, installed in the sides or corners of buildings to discourage their casual use as urinals by passers-by. They may be constructed in various ways from a variety of materials but are typically designed to have an angled surface which catches and redirects the stream.
