Abstract: A urinal includes a urinal body having a top portion, a left sidewall, a right sidewall, and a rear wall, which define an internal cavity, and a bowl having a concave shape. The top portion includes a plenum chamber defined therein, which is configured to receive flush water and is in in fluid communication with the internal cavity of the urinal body via a plurality of baffle holes. A flow restrictor is disposed within the plenum chamber to slow a velocity of water flowing through the plenum chamber. The rear wall of the urinal body includes at least two angled portions extending laterally inward and rearward from the left and right sidewalls. The angled portions meet in a rounded corner. The at least two angled portions and the rounded corner are configured to deflect urine striking the rear wall such that the urine remains within the internal cavity.
