Plumbing and fixture installation covers the pipework and hardware that make a bathroom function: setting supply and drain lines for a new tub or shower, roughing in a relocated toilet, mounting a vanity sink and faucet, connecting a shower valve and head, and hooking up any add-ons like a bidet seat or heated towel bar with a water line. In a remodel, this work usually happens in two passes: rough-in plumbing behind the walls before drywall goes up, then trim-out (faucets, showerheads, toilets, drains) once tile and cabinetry are finished. Norwalk's older housing stock, especially in neighborhoods with homes from the mid-20th century, often means dealing with galvanized or cast iron lines that need updating to copper or PEX during a bathroom project.
When comparing installers, ask whether they pull the required plumbing permit and schedule inspections, since skipped permits can cause problems when you sell the house. Check that they carry liability insurance in case a connection fails and causes water damage, and ask how they handle unexpected issues like corroded shutoff valves or out-of-code venting once walls are opened. Get a written estimate that separates labor, fixtures, and any drywall or tile patching.
