A shower that won’t drain is almost always clogged with hair bound together by soap scum within the first 6–18 inches of the drain. Remove the drain cover, pull out the hair with a plastic drain tool or bent wire, then plunge or run a small drain snake to clear what’s left. If several fixtures drain slowly at once, or water backs up when you flush the toilet, the problem is further down the line and usually needs a plumber.

Why Your Shower Is Not Draining
| Cause | Clue | Fix |
|---|---|---|
| Hair and soap scum | Slows down gradually over weeks | Hair tool, plunger, snake |
| Clogged drain cover or strainer | Gunk visible under the grate | Remove and scrub the cover |
| Hard water scale | White crust in the strainer | Soak parts in white vinegar |
| Small object (cap, razor cover) | Sudden stop after something dropped | Retrieve with pliers or a snake |
| Blocked plumbing vent | Gurgling, slow drains in several fixtures | Clear roof vent (often a pro job) |
| Main sewer line clog | Water rises in shower when toilet flushes | Call a plumber |
How to Unclog a Shower Drain
- Remove the cover. Most shower grates either pop off or are held by one or two screws. Clean them under hot water.
- Pull out the hair. Push a barbed plastic drain tool (or a straightened coat hanger with a small hook) down the drain, twist and pull up slowly. Repeat until nothing comes up.
- Flush with hot water. Run very hot tap water for a minute to carry away loosened soap. Avoid pouring boiling water into PVC drains.
- Plunge it. Use a cup plunger, cover the overflow if your shower is in a tub, add an inch of water and give 10–15 firm strokes.
- Snake it. If the water still sits, feed a 15–25 ft hand auger through the drain and trap, crank it to snag the clog, and pull it back out.

Natural Method: Baking Soda and Vinegar
For a slow (not stopped) drain, pour about ½ cup baking soda into the drain, follow with 1 cup white vinegar, cover for 15–30 minutes, then flush with hot water. It helps loosen soap film but won’t clear a solid hair clog—use it after you’ve pulled the hair.

When to Call a Plumber
- Water comes up in the shower when you flush or run the washer
- More than one drain in the house is slow
- You smell sewage or hear gurgling
- The clog returns within days after snaking
- A tiled shower is leaking around the drain or onto the ceiling below
If your shower is part of a tub, the same tools apply—see our full guide to a clogged bathtub drain, which covers removing tub stoppers and overflow plates.
