In is done from the wall behind the toilet to the centerline of the drain. Most toilets have a 12-inch rough-in, but 10- and 14-inch roughs are also common. Toilets with a 10- or 14-inch rough require an offset flange. An offset flange is also necessary when the toilet is installed on a concrete floor that has been poured around the drainpipe.
When measuring the rough-in, it is important to measure from the wall to the center of the drain, rather than from the edge of the flange. This is because the flange may not be perfectly level, and measuring from the center of the drain will ensure that the toilet is installed at the correct height.
What is toilet rough in size?
The average toilet rough in size is 12 inches.However, 10- and 14-inch roughs are also common. Toilets with a 10- or 14-inch rough require an offset flange. An offset flange is also necessary when the toilet is installed on a concrete floor that has been poured around the drainpipe.

What is a toilet rough and what does it measure?
A toilet rough is the distance measured from the wall behind the toilet to the center of the drain. This measurement is typically 12 inches, although 10- and 14-inch toilets are also common. Toilets with a smaller rough require an offset flange, which is necessary when installing a toilet on concrete floors that have been poured around the drainpipe. In order to accurately measure the toilet rough, it is important to measure from the wall to the center of the drain, rather than from the edge of the flange, as this may not be perfectly level. Additionally, accurate measurement of a toilet rough can ensure that your toilet is installed at the correct height.
How to measure a toilet rough?
There are several steps involved in accurately measuring a toilet rough. The first step is to measure from the wall behind the toilet to the center of the drain, which is typically 12 inches. If your toilet has a smaller rough, such as 10 or 14 inches, you will also need to measure an offset flange to ensure that it is installed correctly. When measuring the rough, it is important to take into account any unevenness or variations in the floor, as this may impact the accuracy of your measurement. Finally, accurate measurement of a toilet rough can ensure that your toilet is installed at the correct height, which is essential for optimal functionality and comfort.
Why is the measurement important?
Accurate measurement of a toilet rough is important for several reasons. First, it ensures that your toilet is installed at the correct height. This can affect both comfort and functionality, as a properly installed toilet should be neither too low nor too high. Additionally, an accurate measurement can help to prevent leakage issues caused by misaligned or uneven flanges. Finally, an accurate measurement can help to ensure that your toilet is operating at peak efficiency and is not wasting water. Overall, measuring a toilet rough accurately is essential for ensuring optimal performance and functionality of your bathroom.
What are some of the factors that can affect the measurement
There are several factors that can affect the measurement of a toilet rough, including variations in the floor and unevenness in the flange. Additionally, if you are installing your toilet on a concrete floor that has been poured around the drainpipe, an offset flange will be necessary to ensure proper alignment. Other potential factors affecting the measurement of a toilet rough include the type of toilet being installed and the distance from the wall to the center of the drain.
