A full bathroom renovation goes beyond swapping out a vanity or regrouting tile. It typically means gutting the room to the studs or subfloor and rebuilding the plumbing rough-in, electrical, waterproofing, tile, fixtures, and ventilation as a coordinated project. In Norwalk, that scope often includes updating older homes' cast-iron or galvanized supply lines, adding proper exhaust ventilation to fight humidity from Long Island Sound's coastal climate, and dealing with tight footprints in pre-war housing stock near SoNo and East Norwalk. We track 42 businesses in this category, ranging from small design-build outfits to larger remodeling firms with in-house crews.
Before you sign a contract, ask about licensing and insurance, who pulls the permits, whether the same crew does the whole job or if trades are subcontracted, and how they handle unexpected issues like water damage or outdated wiring found once walls open up. A written scope with fixture allowances and a realistic timeline matters more than a low bid.
Our scoring weighs verified licensing, review consistency, response time, and the range and quality of completed work described by past clients.
