Drain flange gasket
Urinals come in manual or automatic flush models found in restrooms at rest stops, movie theaters and other public locations. One manufacturer of urinals you can install, American Standard, also offers a variety of toilets. Installing a urinal requires mounting it to a wall and attaching it to the plumbing lines. To do so, you must have the water line and drain plumbed on the wall where you plan to install the urinal.

Measure up from the floor 35-1/4 inches with a tape measure, and locate the wall studs using a stud finder. Measure from the inside of each stud 6-3/4 inches, and make a pencil mark.
Drill a hole into the wall on each mark with a power drill. Place a wall hanger over each hole. Place a washer over a lag screw, and insert it into the wall hanger. Tighten the lag screw with a slotted screwdriver.

Place the urinal on the wall hangers, and position the anchor hole over the drain flange. Use a level to verify that the urinal is sitting level on the wall.
