A typical detail for a urinal refers to the standard construction and installation specifications used in architectural or plumbing design to ensure proper functionality, hygiene, and maintenance.
This detail generally includes the urinal fixture, flush valve or flushometer, water supply line, drainage connection (P-trap or concealed trap), wall backing, and mounting height.
Urinals are usually mounted at a height of 24 to 30 inches from the finished floor (measured to the rim), with lower mounting for accessibility-compliant installations (around 17 inches for ADA compliance).
The wall behind the urinal is often reinforced to support the fixture’s weight and is finished with tile or waterproof material for easy cleaning. The flush valve is typically located above the urinal, connected to a cold water supply line, while the waste line connects to the building’s sanitary drainage system, often concealed behind the wall.
Additional details may include privacy panels, venting provisions, anti-splash designs, and trap primer systems in commercial restrooms.
These details ensure that the urinal is sanitary, durable, and easy to use, and they are typically illustrated in construction drawings for accurate implementation by contractors and plumbers.
