A slow-draining or fully blocked bathtub is usually the result of hair, soap scum, and everyday grime collecting at the drain opening and in the trap. The good news: many clogs can be cleared quickly with the right approach and a little patience.

Start with the easiest checks

Before using stronger methods, confirm the blockage source. Remove the drain stopper or cover (if applicable) and look for visible hair or residue. If you can reach it, pull it out with gloves or a paper towel-wrapped tool to avoid pushing material deeper.

If the drain is covered by a pop-up stopper, check for trapped hair around the mechanism and around the overflow path. Sometimes the “clog” is actually a stuck stopper or residue collecting at the edge of the drain assembly.

Use a drain snake or auger for hair-heavy clogs

For clogs you can’t see, a drain snake (hand auger) is often the fastest reliable option. Feed the cable slowly into the drain until you feel resistance, then rotate to catch and break up the clog. Pull the snake back and repeat if needed.

Tip: work in short cycles—advance, rotate, withdraw—to prevent compacting the blockage. Wipe the cable after each pull to inspect what you’ve removed.

Try a plunger—properly

A plunger can work well when the blockage sits higher in the drain line. Use a cup plunger (not a flat one), seal the rim of the tub, and push firmly with quick upward thrusts. After several attempts, run hot water to flush loosened debris.

Be careful: plunging won’t help much if the clog is deep or fully impacted in the pipe, but it can quickly clear partial blockages and improve flow enough for the next step.

Hot water and mechanical clearing for soap scum

If the drain is slow rather than completely blocked, soap scum may be narrowing the pipe. Pour hot (not boiling) water in stages to avoid shocking the system. Follow with a gentle mechanical clearing step, such as removing the stopper and using a flexible brush or small tool to dislodge residue.

For persistent buildup, a targeted enzymatic drain cleaner can help break down organic matter over time. These products typically work best when used after removing standing water and hair where possible.

Avoid common mistakes

Do not rely on repeated drain cleaner “shots” without identifying the cause, especially if you’ve already removed hair or debris from the visible area. Aggressive chemical treatments can be ineffective against solid hair clumps and may create additional residue.

Also, avoid forcing objects deep into the drain that can snag and worsen the blockage. If water backs up, stop and switch to a snake/auger or check the overflow/adjacent connections.

If these methods don’t restore drainage, the blockage may be farther down the line (or involve a damaged trap). In that case, a licensed plumber can inspect the pipe run and clear it efficiently using the right equipment.

With a systematic approach—clear what you can reach, use a snake for hair clogs, and apply hot water and plunging for partial flow issues—you can often get your bathtub draining normally the same day.
