Water pooling in the basin while you brush your teeth is a small problem that grows fast. Most homeowners can unclog bathroom sink drains without calling anyone, because the cause is almost always the same: hair, soap scum, and debris collecting just past the stopper. This guide walks through the fixes that work, in the order worth trying them.
Key Points
- Hair, soap scum, foreign objects, mineral buildup, and damaged pipes cause nearly every slow bathroom sink
- Boiling water is the simplest fix, but skip it if your sink is porcelain
- Baking soda and vinegar clear minor blockages and leave the drain smelling fresh
- A cup plunger and a drain snake handle what boiling water cannot reach
- A drain strainer and a weekly stopper cleaning prevent most repeat clogs
