To clear a clogged bathroom sink with standing water, first bail out the basin using a cup and a small bucket. Next, remove the pop-up stopper and fish out hair with a Drain Snake or a bent wire hanger. If that fails, clear the blockage at the P-trap beneath the sink.
Unclog A Bathroom Sink: 5 Easy Methods
Unclog a Sink with a Plunger
To unclog a sink with standing water, first bail out the excess water into a bucket. Then, remove the sink stopper, as it is often coated in hair and debris. Finally, pour a mixture of baking soda and vinegar down the drain, let it sit, and flush it with boiling water.
A straightforward yet effective approach to addressing a clogged drain pipe involves simply using hot water mixed with dish soap. This method, ideal for tackling minor blockages, leverages the degreasing power of dish soap combined with the force of hot water to dislodge and dissolve clog-causing residue.
Baking soda and vinegar do not effectively unclog drains. Instead of clearing debris, mixing them chemically neutralizes both ingredients into salt water. The fizzing reaction is visually satisfying but largely escapes upwards, offering zero power to dissolve grease, hair, or stubborn sludge.

After removing standing water from the sink, pour about half a cup of table salt down the drain before you pour in the hot water. Let it sit for a few minutes, and then flush with hot water to clear the mixture.
Pouring salt down your drain at night is a popular DIY plumbing trick used for routine maintenance. The goal is to take advantage of the salt's coarse texture and natural moisture-absorbing properties.

The "135-degree rule" in plumbing states that the total (aggregate) horizontal change in direction for a drainage pipe—specifically trap arms—cannot exceed 135 degrees between the P-trap and the vent. Exceeding 135 degrees (such as using three 45-degree bends or a 90 and two 45s) requires a cleanout because sharp turns hinder flow and cause clogs.
It's best to instead opt for a Drano alternative as a safer and more plumbing-friendly way to unclog your drains. Some of the best Drano alternatives include using a plunger or pipe snake, soap or salt mixed with boiling water, or baking soda and white vinegar.
