Pull the drain cover and take out whatever hair you can reach. That fixes most clogged showers and tubs. If water still pools after that, run the hot tap, plunge with the overflow plugged, then use a plastic drain tool. Baking soda and vinegar loosens soap film but rarely moves hair. When water backs up in a second fixture, a local plumber is the faster call. Everything below follows the same order, with the Burbank details that change the answer. The wider drain cleaning and clogs guide sits behind this one.
How do I unclog a drain?
Begin with the cheapest step and work upward: lift the cover, pull out the hair, rinse with hot tap water, plunge, and finally reach for a plastic drain tool or hand auger. Each step takes minutes. Stop moving up when a step produces no change, because the clog is probably lower than your tool reaches and further effort mostly adds risk.
A practical sequence for a shower or tub:
- Unscrew or lift the strainer and pull out the hair. Wear gloves.
- Let the hot tap run for about a minute and watch whether the water drains.
- Block the overflow opening with a damp rag so the plunger can build pressure, then give ten or fifteen firm strokes.
- Push a barbed plastic strip down the drain, pull it back out slowly and clear what comes with it.
- Flush again with hot water.
A hair clog often sits within the first foot or so of pipe, which is why the strip tool does most of the work.
What can I pour down my shower drain to unclog?
Safe pours include very hot tap water, a baking soda and vinegar mix, or a label-directed commercial opener. The mix is the gentlest choice: baking soda first, then white vinegar, each about a half cup, with the drain covered for fifteen minutes before a hot water rinse. It fizzes, and it softens soap residue.
Be realistic about it. The fizz moves soap scum, not a wad of hair. The fair test is whether the pool drains faster after one round. If not, switch to a mechanical method, since a second pour just leaves liquid sitting on the clog. Our guide to natural drain remedies compares the home options side by side.
Is Drano safe for shower drains?
A commercial caustic opener is designed to dissolve hair and soap, but it is a hazardous product, and its safety depends on your pipes and on how you use it. Read the label on your own bottle, never combine it with vinegar or another cleaner, ventilate the room and keep it off skin and eyes. Do not use it if the drain is already full of another product.
Old pipes matter in this part of California. Homes built in the 1940s through the 1960s in the San Fernando Valley can have galvanized or cast iron branch lines, and a corroded pipe can weaken further when a harsh product sits in it. If you use a chemical and the water does not move, call a plumber and say which product and when, so they handle the standing liquid carefully.
What is the fastest way to unclog a shower drain?
The quickest tool is a barbed plastic drain strip: push it down, then pull it out, hair and all. The job takes under five minutes, and the strip sells for a few dollars at any hardware store. A plunger is next fastest, but only if the overflow is blocked off so pressure goes down the pipe instead of out of it.
Skip the metal snake unless you have used one. It can scratch a fiberglass or acrylic base. If a plastic strip brings up nothing and the water still sits, the clog is farther along, probably past the trap. That is the point where a plumber's cable machine does the job in one visit.
How do I get a severely clogged toilet unclogged?
A severe toilet clog needs a flange plunger first, then a closet auger. Seat the plunger firmly over the outlet, push gently so nothing splashes, then pull back hard. Repeat ten to fifteen times. When the water will not budge, work a closet auger down into the bowl, turn its handle and draw back whatever it snags.
When neither works, the clog is past the toilet or the object is solid. Stop, shut the supply valve and call a plumber. A toilet that clogs more than once a month usually has a line or flange issue and not a bowl issue. Our blocked toilet guide lays out the sequence closely.
How do I clear a clogged vent, kitchen drain or garbage disposal?
A gurgling drain, slow flow in several fixtures and a sewer smell together suggest a blocked plumbing vent on the roof, and because roof access is involved, that job belongs to a plumber. A clogged kitchen drain usually holds grease; clear it with hot water and a plunger. A garbage disposal that hums but will not spin needs to be switched off first.
For a jammed disposal, cut the power at both the switch and the breaker, then turn the shaft with the hex wrench from the underside to free it. Never put a hand in the chamber. Press the reset button, then test with water. Our page on unclogging a garbage disposal drain has the steps, and a separate guide covers clearing the bathroom sink as well.
When should I call a plumber for a clogged shower or tub?
Bring in a plumber if at least two fixtures are slow, a toilet bubbles when the shower empties, the clog returns inside a month, or a chemical product achieved nothing. Each indicates a blocked branch or main line, which a local plumber with a machine can clear in a single visit.
Published national figures put clearing a bathroom drain, shower or tub at about $150 to $225, with the wider range for drain clogs at $150 to $350. That is a guide, not a quote. A local plumber can be booked, and the price is set out in writing before work begins. Ask on the quote page, or start from the home page. For detailed pricing, read the guide to unclogging costs for drains and toilets.
Questions people ask
Which liquids are safe to pour into a clogged shower drain?
Options are hot tap water, baking soda then white vinegar, or a commercial opener used exactly per its label. Add one product at a time and give it time before judging. Hair is better pulled out by hand. Never pour a second product on top of the first, because mixed cleaners can release harmful fumes.
Can dish soap such as Dawn clear a drain?
Dish soap mainly helps with grease. A squirt of dish soap followed by hot water makes a greasy kitchen drain slip along. In a shower the clog is hair held together with soap, and dish soap does not loosen hair. Use it as a gentle first move on a kitchen drain, and use a hair tool for a shower.
Can a blocked vent make my shower drain slowly?
Yes. Water moves cleanly through a drain only when air can follow behind it. A blocked vent slows several fixtures, produces gurgles and sometimes pulls water out of a trap, letting a sewer smell in. Because the vent exits through the roof, and the cause is often a nest or debris, have a plumber check it.
How do I keep my shower drain from clogging again?
Install a fine mesh drain catcher and clean it out after every shower. Run hot tap water through the drain weekly, and pull the strainer for a quick hair clean every month. This does more than any pour-in product. If the drain slows within weeks of clearing, ask the plumber to look in the line with a camera.
Why does my tub drain slowly even after cleaning the stopper?
If the stopper is clean and the tub still drains slowly, the hair is probably lower, in the trap or the tub waste line. Pull out the pop-up or lift lever assembly and check the linkage, since hair collects on it. If it is clear, the blockage is deeper, and a cable machine reaches it.
