How to Unclog a Shower Drain: 7 Methods That Work
Most shower clogs are hair. Remove the drain cover, pull the hair out with a barbed tool or pliers, then flush with hot water. Use a snake if it's deeper.
How to unclog a shower drain: remove the drain cover, pull out the hair with a plastic barbed tool, needle-nose pliers or a bent wire, then flush with hot water. Nearly all shower clogs are hair tangled with soap scum just a few inches below the drain, so this takes about 15 minutes and no chemicals.
If that doesn’t clear it, a plunger, a wet/dry vacuum or a hand drain snake will reach deeper clogs. The steps below go from quickest to most involved, with notes on when a plumber is the smarter call.
1. Remove the drain cover
Most shower drain covers either pop off with a flathead screwdriver or are held by one or two small screws. Some twist out counterclockwise. Every method for how to unclog a shower drain starts here.
In a bathtub, the stopper may be a lift-and-turn, push-pull or toe-touch type that unscrews, or a trip lever stopper connected through the overflow plate. Lay a towel in the tub so small screws don’t fall into the drain.
2. How to unclog a shower drain by pulling out hair
Once the cover is off, you’ll often see the clog right away. A plastic barbed drain cleaning strip, sold for a few dollars at hardware stores, is the easiest tool: push it in, twist and pull it out slowly.
Needle-nose pliers or a straightened wire hanger with a small hook at the end also work. Wear gloves, keep a trash bag nearby and repeat until the tool comes out clean.
3. Flush with hot water and dish soap
After removing hair, pour a squirt of dish soap and a kettle of hot water down the drain to rinse soap scum and residue. If your drain pipes are PVC, use hot tap water rather than boiling water, which can weaken plastic joints over time.
Run the shower for a minute. If the water now drains quickly, replace the cover and you’re done.
4. Use a plunger for standing water
If water is standing in the shower, a cup plunger can push the clog loose. Make sure there’s enough water to cover the rubber cup, and for a bathtub, block the overflow opening with a wet rag so pressure isn’t lost.
Plunge firmly 15 to 20 times, then pull off quickly. A little petroleum jelly on the rim helps the plunger seal on a flat shower floor.
5. Try a wet/dry vacuum
A shop vacuum set to wet mode can pull a clog back up the pipe. Remove the cover, seal the hose around the drain with a wet rag, and run the vacuum on its highest setting for a minute or two.
This is a good option for how to unclog a shower drain with standing water, since the vacuum can remove the water and the clog in one go.
6. How to unclog a shower drain with a snake
When the clog is past the trap, a hand drain snake, usually 15 to 25 feet long, is the next step. Feed the cable into the drain, turn the handle as you push, and keep rotating when you hit resistance.
Pull the cable back slowly and clean off the debris. For bathtubs, feeding the snake through the overflow opening often gives a straighter path than going through the drain.
7. Chemical and enzyme cleaners: know the risks
Caustic gel drain cleaners can dissolve hair, but they’re strong chemicals. They can burn skin and eyes, damage some finishes and older pipes, and make it dangerous to plunge or snake afterward because of splashing.
If you use one, read the label, wear gloves and eye protection and ventilate the bathroom. Never mix drain cleaners or combine them with bleach, and never mix bleach with ammonia or acids like vinegar. Enzyme cleaners are safer for monthly maintenance but too slow for a full clog.

When to call a plumber
If you’ve tried every method for how to unclog a shower drain and it’s still slow, or water comes up in the shower when you flush the toilet, the clog is likely in the branch or main line. That needs a licensed plumber with a motorized auger or a camera.
A basic drain-clearing visit commonly costs about $100 to $300. If a slow leak has damaged the subfloor or ceiling below, call your homeowners insurance to ask whether the damage is covered.
FAQ
What will dissolve hair in a shower drain?
Caustic chemical drain cleaners can dissolve hair, but they carry real safety risks. Removing the hair mechanically is faster and safer in most cases.
What is the fastest way to unclog a shower drain?
Remove the cover and pull the hair out with a barbed plastic tool. It usually takes less than 15 minutes and fixes most shower clogs.
Can you pour Drano in a standing water drain?
Some products say they can work through standing water, so check the label. The water dilutes the chemical, and if it fails you’re left with caustic water in the shower. Removing the water and the hair first is safer.
How do you prevent shower drain clogs?
Use a hair catcher over the drain, clean it after each shower and flush the drain with hot water once a week.
Bottom line
Learning how to unclog a shower drain comes down to one thing: get the hair out. Remove the cover, pull the clog with a barbed tool, flush with hot water, and move to a plunger, vacuum or snake only if needed. Use chemicals sparingly and call a plumber when other drains are affected.
