Sewage smell in the bathroom? Here's Who to Call
A persistent sewage or rotten-egg smell in a bathroom usually means sewer gas is escaping past a defence that should block it — a dried-out drain trap, a failed toilet wax seal, or a blocked or missing vent pipe. Beyond the odour, sewer gas is unpleasant and, in high concentrations, unhealthy. A plumber can trace the source, refill or repair the trap, reseat the toilet, and clear the vent so the smell stops for good.
