    A clogged shower drain sounds like a small inconvenience, but it can become problematic if left untreated.

    Reasons for Shower Drain Clog

    A clogged shower drain is an issue that creates an unpleasant odor. Hence, working on its root cause is as essential as unclogging the drain. Here are some reasons that can cause the shower drain to clog.

    Hair build-up: During the shower, a few strands of hair get collected over time. When combined with soap and other debris, it can clog the drain. This is the primary reason that blocks the shower drain.

    Mineral accumulation: A hard water supply contains many minerals such as calcium and magnesium. These minerals accumulate over time, making the pipe smaller from the inside, causing the water to begin to drain slowly.

    Soap and shampoo remnants: Every soap and shampoo leaves its remnants behind, which, when combined with other elements, causes a shower drain to clog up.

    Foreign elements: This is the most common reason for a shower drain to clog. Different objects such as small toys, jewellery, or hygiene products can accidentally end up in the drain, causing hindrance in the water drainage.

    Intrusive tree roots: Tree roots naturally look for water sources. If there are underground pipes carrying water, roots may find their way into the drain. This can lead to blockages and can be a threat to the plumbing system.
