How to Fix a Clogged or Slow-Draining Shower or Tub
Standing water in your shower or a tub that takes forever to drain is almost always caused by hair tangled around the drain crossbars or caught in the drain assembly. This is one of the easiest plumbing fixes — no tools required in most cases.
What's Happening
Hair combines with soap scum to form a tangled mass that catches on the drain cover or collects just below the opening. Over weeks and months, this wad grows until water can barely pass through. The clog is almost always within the first 6 inches of the drain — well within reach.
What to Check
- Remove the drain cover. Most shower drain covers pop off, unscrew, or have a single screw in the center. For tubs, unscrew or pull up the stopper — some twist and lift, others have a set screw on the side. Set it aside.
- Pull out the hair clog. Look into the drain with a flashlight. Use needle-nose pliers, a bent wire hanger, or a $3 Zip-It drain cleaning tool (a barbed plastic strip) to hook and pull out the hair mass. This is the fix 90% of the time.
- Flush with hot water. Run hot tap water for 2-3 minutes to flush away remaining debris. Watch the drain speed — it should be noticeably faster.
- Try baking soda and vinegar for stubborn clogs. Pour half a cup of baking soda down the drain, followed by half a cup of vinegar. Wait 15 minutes, then flush with hot water. This breaks down soap scum buildup deeper in the pipe.
- Use a plunger for deeper clogs. If water is still pooling, fill the tub or shower base with a couple inches of water. Use a flat cup plunger directly over the drain. Pump firmly 15-20 times to dislodge anything deeper in the P-trap.
Call a Pro If
- Water backs up into other drains when the shower runs
- You've cleared visible hair but drainage is still very slow
- Multiple fixtures drain slowly (indicates a main line issue)
- There's a persistent sewage smell from the drain
Frequently Asked Questions
How do I prevent shower drain clogs?
Use a mesh drain cover or hair catcher ($3-5). Clean it after each shower to catch hair before it enters the pipe.
Is standing water in the shower dangerous?
Not immediately, but it promotes mold and mildew growth and signals a clog that will only worsen.
Can I use a drain snake on a shower drain?
Yes. A hand-crank drain snake works well for clogs deeper than you can reach by hand. Feed it slowly until you feel resistance.
Still Draining Slowly After Clearing the Hair?
Record a video of your slow shower or tub and Toolbox determines if the blockage is right at the drain, deeper in the line, or a sign of a venting issue.
