The answer to 'why is my shower slow draining' is that a slow-draining shower is usually caused by a clogged drain. This can happen when hair, soap scum, and other debris build up in the drain pipe, restricting the flow of water. Slow draining can also be a sign of a deeper plumbing issue, such as a problem with the main sewer line.
Some common symptoms of a slow-draining shower include water pooling in the shower base, water draining slowly, or the shower not draining at all. If left unaddressed, a slow drain can lead to unpleasant odors, potential water damage, and even a complete blockage.
