Short answer: Bathroom drains most commonly clog from hair combined with soap scum, which binds together inside the pipe and gradually restricts flow in sinks, tubs, and showers.
Hair is the single biggest cause of slow bathroom drains, especially in showers and tubs. On its own it might rinse through, but combined with soap scum and skin-care product residue, it forms a mass that clings to the inside of the pipe.
Bathroom sink clogs tend to happen closer to the drain opening than kitchen clogs do, which sometimes makes them easier to reach and clear.
Signs You May Need This Service

What the Service Typically Involves
- Identifying whether the clog is local to one fixture or further down the line
