The answer to 'shower slow draining' is a clogged drain. A slow-draining shower is typically caused by a buildup of hair, soap scum, or other debris in the drain pipe. This can restrict water flow and cause the shower to drain slowly.
Some common signs of a clogged shower drain include water taking longer to drain, water pooling in the shower, or a gurgling sound coming from the drain. If left unchecked, a slow-draining shower can eventually lead to a complete blockage and overflow.
