How to Clear a Bathtub Drain Clog

Direct answer: To clear a bathtub drain clog, remove standing water, pull out hair and soap buildup from the drain opening, then run a small hand snake through the drain until water flows freely again.

Most bathtub clogs are caused by hair and soap scum collecting just below the drain or near the stopper. Start with the simple cleanup you can reach by hand, then move to a small drain snake if the clog is deeper.

Before you start: Choose a small hand drain snake or hair removal tool made for tub and shower drains, not a large toilet auger. Stop if the repair becomes unsafe or unclear.

Step-by-step fix

Step 1: Make sure this is the right repair

  1. Check what the tub is doing. This guide fits a tub that drains slowly, backs up around your feet, or holds water after use.
  2. Run a little water and watch the drain. If the water rises quickly but the faucet and shower work normally, the problem is usually a drain clog.
  3. Look at the drain opening for visible hair, soap scum, or a stopper that is stuck partly closed.
  4. Remove bath mats and anything around the tub that could get wet or slippery.

If it works: You have confirmed the problem is a clogged bathtub drain, not a water supply issue.

If it doesn’t: If the tub drains normally and the problem is overflow, leaking, or a faucet issue, use a different repair path.

Stop if:
  • Water is coming up in another fixture like a toilet or nearby sink, which can point to a larger drain line blockage.
  • You see sewage, strong sewer backup, or leaking under the tub or through the ceiling below.

Step 2: Set up the tub and open the drain area

  1. Put on gloves and scoop or bail out most of the standing water with a bucket or large cup.
  2. Remove the drain cover if it lifts out or is held by screws.
  3. If the tub has a stopper, lift, twist, or unscrew it as needed so you can reach the drain opening clearly.
  4. Lay a rag nearby for the debris you pull out.

If it works: The drain opening is exposed and easy to reach.

If it doesn’t: If you cannot remove the stopper without forcing it, leave it in place and use the hair removal tool through the available opening.

Stop if:
  • The drain parts are badly corroded, cracked, or loose enough that they may break apart during removal.

Step 3: Pull out the clog you can reach

  1. Insert the plastic hair removal tool straight into the drain as far as it will go without forcing it.
  2. Twist slightly and pull it back out slowly to catch hair and soap buildup.
  3. Repeat several times until the tool comes back cleaner.
  4. Wipe debris into the rag or paper towels and throw it away instead of rinsing it back into the drain.

If it works: You removed visible hair and sludge from the top section of the drain.

If it doesn’t: If the tool will not go in far or comes back clean while the tub still drains slowly, move on to snaking the drain.

Stop if:
  • The tool hits a solid obstruction immediately and the drain assembly feels loose or damaged.

Step 4: Snake the drain to reach a deeper clog

  1. Feed a small hand drain snake into the tub drain slowly.
  2. Turn the handle as you push so the cable follows the bend in the drain instead of jamming.
  3. When you feel resistance, keep turning and work the cable back and forth to break through or grab the clog.
  4. Pull the snake out carefully and clean off any hair or sludge.
  5. Run the snake in again once or twice if needed until it moves more freely.

If it works: The snake passes through the clog area and brings back debris or opens the line.

If it doesn’t: If the snake will not get past the trap or the drain is still blocked, the clog may be farther down the line and may need a longer cable or a plumber.

Stop if:
  • The cable binds hard, the drain piping shifts, or you hear cracking behind the wall or under the tub.

Step 5: Flush the drain and reassemble the parts

  1. Run hot water into the tub for a minute or two to carry loosened residue through the drain.
  2. Watch the water level closely to make sure it is dropping instead of rising.
  3. Reinstall the stopper and drain cover once the water is moving well.
  4. Wipe the tub clean so leftover sludge does not stain the surface.

If it works: The tub drains faster and the drain parts are back in place.

If it doesn’t: If the tub still drains slowly, repeat the snaking step once more before deciding the clog is deeper in the branch line.

Stop if:
  • Water leaks from the drain assembly, overflow area, or ceiling below while testing.

Step 6: Confirm the repair holds during normal use

  1. Fill the tub with a few inches of water, then let it drain all at once.
  2. Watch for smooth draining without bubbling back, standing water, or water creeping up around the stopper.
  3. Use the tub normally for the next shower or bath and check that it still clears at a normal speed.
  4. Clean the stopper regularly going forward so hair does not rebuild in the same spot.

If it works: The tub drains normally in real use and the clog is cleared.

If it doesn’t: If the tub backs up again soon, the blockage is likely deeper in the drain line and professional drain cleaning is the next step.

Stop if:
  • The tub repeatedly backs up after cleaning, or multiple fixtures are draining slowly at the same time.

FAQ

What usually clogs a bathtub drain?

Hair is the main cause, and soap scum helps it stick together into a mat just below the drain or near the stopper.

Should I use a chemical drain cleaner first?

Manual removal is usually the better first step for a tub clog. It is safer for you, easier on drain parts, and often works better on hair clogs.

Why does the tub clog again soon after I clear it?

That usually means part of the clog is still deeper in the line, or the stopper keeps catching hair and rebuilding the blockage.

Can I use a toilet auger in a bathtub drain?

No. A toilet auger is shaped for toilets and can damage or scratch tub drain parts. Use a small hand snake or a plastic hair removal tool instead.

When should I call a plumber for a bathtub clog?

Call if the clog keeps returning, the snake cannot reach it, water backs up in other fixtures, or you notice leaks or signs of a larger sewer problem.
