Plumbing and fixture installation covers the work that turns a bathroom remodel from a shell into a functioning room: setting toilets, sinks, and vanities, running or rerouting supply and drain lines, installing shower valves and trim, mounting tub or shower units, and connecting fixtures like bidets, freestanding tubs, or wall-hung sinks that need extra bracing and venting. It's separate from cosmetic tile or paint work, though the two often overlap on the same job, since a licensed plumber usually needs to rough-in lines before drywall or tile goes up, then come back to set the finished fixtures.
We track 7 businesses in New Haven that do this kind of work. When comparing them, look at whether they carry a Connecticut plumbing license (not just a general contractor license), whether they pull permits for rough-in work, and how they handle unexpected issues like old galvanized pipe or cast iron drain lines that are common in New Haven's older housing stock, from Wooster Square triple-deckers to East Rock colonials. Ask for a written scope that separates rough-in from trim-out, and find out who's liable if a fixture fails after install.
Our scoring weighs licensing, verified reviews, response time, and the consistency of past work rather than just star counts.
