Rough-in is an important early stage in plumbing work where plumbers install the basic pipe system before walls and floors are finished. It's like creating the skeleton of the plumbing system - putting in pipes, vents, and drain lines, but not yet installing the visible fixtures like sinks or toilets. This stage needs to be done correctly as it will be hidden behind walls later. Think of it as similar to how electricians put wiring in walls before they're closed up. When you see "rough-in experience" in a resume or job posting, it means the person knows how to plan and install these initial plumbing systems.
