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.
Toilets with 4-inch drains are less likely to get stopped up. Waste drain pipes for toilets in modern plumbing systems are either 3 inches or 4 inches in diameter. The wider the pipe, the more waste it can move and the less likely it will be to clog. A 4-inch pipe can carry about twice the waste of a 3-inch pipe.
