A concealed wall-mounted folding urinal has a main body adapted to be mounted on an internal wall of a bathroom or lavatory. A tray is pivotally attached to the main body for movement between a first, standby, position and a second, ready for use, position in which the tray is ready to receive urine from a male person standing before the urinal. A sensor detects the presence of a person within a predetermined distance of the urinal, whereupon an actuating mechanism pivots the tray from the first position to the second position. When the sensor detects the absence of a person within a predetermined distance of the urinal, the actuating mechanism pivots the tray from the second position to the first position, whereupon the urinal is flushed with water.
