The term “rough-in” in plumbing refers to the initial, unfinished stage of installation. It’s called “rough-in” because it involves positioning and installing the basic framework of pipes and fixtures before the finishing touches, such as drywall and decorative fixtures, are added.
A rough-in valve, also known as a rough-in shower valve, is a component installed during the rough-in phase of plumbing. It’s typically used for showers and tubs and serves as the connection point for hot and cold water supply lines.
