Measuring for a toilet replacement is a relatively simple process, but it is important to get the measurements right in order to ensure a proper fit. Here are the steps involved in measuring for a toilet replacement:

1. Measure the distance between the wall and the center of the toilet flange. This measurement will determine the width of the new toilet.
