Bath and Shower Habits That Cause Plumbing Problems (and What to Do Instead)
By Mike Holt, NJ Master Plumber · October 4, 2024 · 3 min read · Updated November 1, 2026
Quick answer
The bathroom habits that cause the most plumbing trouble are letting hair go down the drain, flushing wipes, using chemical drain cleaners, dropping bleach tablets in the toilet tank and hanging heavy caddies on the shower arm. A drain catcher, a trash can by the toilet and a stand-alone caddy prevent most of the clogs and leaks we see in bathrooms.

Most bathroom plumbing calls start with something small that happens every day, like hair washing down the drain or a wipe going into the toilet. Here are the habits we see behind the most common bathroom clogs and leaks, and simple swaps that prevent them.
Which bathroom habits cause the most plumbing problems?
| Habit | What it causes | Do this instead |
|---|---|---|
| Letting hair go down the drain | Slow and clogged tub and shower drains | Use a hair catcher and empty it often |
| Flushing "flushable" wipes | Toilet and main line clogs | Throw wipes in the trash |
| Pouring in chemical drain cleaner | Damaged pipes, hazardous water for the next repair | Pull the clog with a drain tool or call us |
| Drop-in bleach tablets in the tank | Worn flapper, running toilet | Clean the bowl with a brush |
| Heavy caddy on the shower arm | Loose shower arm, leak inside the wall | Use a stand-alone or suction caddy |
| Ignoring a running toilet or drip | Wasted water, worn parts, higher bills | Fix it while it's small |
| Long hot showers with no fan | Moisture damage to caulk and grout, mold | Run the exhaust fan during and after |
Why is hair the biggest shower drain problem?
Hair tangles with soap scum just below the drain cover and forms a mat that catches everything after it. It happens slowly, so the drain gets a little slower each week until water pools around your feet. A hair catcher costs a few dollars and stops most of it. If the drain is already slow, our shower drain guide shows how to pull the clog out without chemicals.
Why shouldn't you flush wipes?
"Flushable" means the wipe fits down the toilet. It doesn't mean it breaks apart. Wipes stay strong in water, so they catch in the toilet's trap, in older cast iron pipes and at joints where roots have gotten in. Paper and grease build up behind them until the main line backs up. Put wipes, cotton swabs, floss and paper towels in a trash can next to the toilet. Our plumbing myths article covers a few more things people think are safe to flush.
What's wrong with chemical drain cleaners and tank tablets?
Chemical drain cleaners rarely dissolve a hair clog completely, and repeated use can damage older metal pipes. If the clog stays, the drain is now full of caustic water that splashes on whoever opens it next, including you.
Drop-in bleach tablets sit in the toilet tank and slowly break down the rubber flapper and seals. A worn flapper lets water leak into the bowl, and the toilet runs or refills on its own. If yours already does that, see how to fix a running toilet.
Can a shower caddy really cause a leak?
The shower arm is a short pipe threaded into a fitting inside the wall. A caddy loaded with full bottles hangs its weight on that arm every day. Over time it can loosen the threads or crack the fitting, and the leak happens behind the tile where you can't see it. The first sign is often a stain on the ceiling below. A caddy that stands on the floor or a shelf in the shower avoids the problem.
What else helps keep bathroom plumbing healthy?
- Run the exhaust fan during your shower and for 20 minutes after.
- Fix a dripping faucet or a running toilet right away.
- Know where the shutoff valve behind the toilet is, and make sure it turns.
- Clean the tub stopper and drain cover every few weeks.
- Keep bath oils and bath bombs occasional, and run hot water after.
When should you call a plumber?
Call if a drain stays slow after you've cleaned it, more than one drain backs up at once, the toilet keeps running, or there's water where it shouldn't be. Several slow drains at once usually point to the main line, which needs professional drain cleaning.
