Taking a bath can be a relaxing pastime, but what happens when there is a bathtub drain odor? You cannot relax if you start to smell something foul. That's because it is not uncommon for a bathtub to form an ugly and smelly buildup of soaps, shampoo, and hair due to daily use. Sometimes, these items gather and form a puddle of gunk that sticks to the pipes and the drain, causing an unsightly odor if not removed. Usually, it either smells like strong sulfur, rotten eggs or even a nasty mildew.
