The standard size for a toilet drain pipe is 3 inches in diameter, but drains up to 4 inches in diameter are often used. The drain pipe connects to the flange, which mounts the toilet itself, and this flange is usually built to connect to 3-inch, schedule 40 toilet drain pipe.
Bar sinks typically use the standard 3 1/4-inch drain size like a kitchen sink. They also use 1 1/2-inch drainpipes and P-traps. A laundry sink drain is 1 1/2 inches in diameter and uses a 1 1/2-inch drainpipe and P-trap. A whirlpool tub uses a 1 1/2-inch drain with the same size drainpipe and P-trap. Other drains follow similar dimensions. Drain sizes are usually chosen based on how much volume of drainage is needed.
