A line of Gents Urinals, in a large hotel, Leeds, West Yorkshire, England, UK

A urinal is a sanitary plumbing fixture for urination only. Urinals are usually used in a standing position and are popular with male users. Urinals can be with automatic or manual flushing, or without flush water as is the case for waterless urinals. They can be arranged as single sanitary fixtures (with or without privacy walls) or in a trough design without privacy walls. The term "urinal" may also apply to a small building or other structure containing such fixtures. It can also refer to a small container in which urine can be collected for medical analysis, or for use where access to toilet facilities is not possible, such as in small aircraft, during extended stakeouts, or for the bedridden. Urinals designed for females ("female urinals") also exist on the market but are not widespread. It is possible for females to use male urinals with a female urination device. Urinals for high throughput capacity are part of an efficiently designed washroom architecture. Large numbers of them are usually installed along a common supply pipe and drain. There may or may not be partitions installed for privacy. Urinals in high-capacity washrooms are usually arranged in one or more rows directly opposite the door, so that users have their backs to people entering or standing outside. Urinals in the street may be arranged in a circle, with all users facing the center, with partitions high enough that they cannot wet each other, and usually high enough that they cannot see over. In a street urinal with an outside screen or wall, the users may stand back to back. Often, one or two of the urinals, typically at one end of a long row, will be mounted lower than the others; they are meant for the disabled and other users who cannot reach the regular urinals. In facilities where people of various heights are present, such as schools, urinals that extend down to floor level may be used to allow anyone of any height to use any urinal. Instead of individual fixtures, trough urinals
