If you have an offset toilet flange, you can move your toilet roughly 2 inches (ca. 5 centimeters) in any direction, allowing you to install your toilet seat while the drainpipe is close to the wall. However, if you install the flange incorrectly, or you choose the wrong size, it might be impossible to position it as intended.

Before buying an offset flange, you will first need to determine the size of your toilet’s drainpipe. The standard drainpipe size is 3 inches, but some are 4 inches in diameter. Apart from an offset closet flange, you will also need to buy a wax ring and toilet mounting bolts.

Offset toilet flanges are used when the drain pipe is not aligned with the toilet bowl. The most common offset is 3-inch, but there are also 4-inch and 6-inch offsets. Toilet flanges come in a variety of sizes, so it’s important to measure the offset before purchasing a flange.

Offset toilet flanges come in a range of inlet and outlet size configurations: 3” inlet/3” outlet : This is the most common type used to connect a toilet to a 3” drain pipe. 3” inlet/4” outlet : Used if the existing drain pipe is 3” but the new flange connection needs to be 4”.
