What is a rough in?

A rough-in typically refers to the stage of construction where the basic plumbing, electrical, and other structural elements are installed before any finishing work is completed. This includes things like piping, wires, ductwork, and framing, which are necessary to get a building or room ready for final installations. Rough-ins are usually necessary for any kind of construction project, as they establish a basic infrastructure and layout that will be used during the rest of the build. Additionally, rough-ins typically need to be carefully planned and executed to ensure that they meet local building codes and will ultimately support the finished construction.
