Drain Clearing & Hair Trap Care
Updated February 20, 2026
Shower drains clog more than any other drain in the house. Hair, soap scum, and conditioner combine into a sticky mass that grabs onto the pipe walls and grows over time. Standing water in the tub during a shower is the early warning. A completely blocked drain with sewage backing up is the late warning. Prevention takes 30 seconds per shower; clearing a full clog takes an hour and sometimes a plumber.

What to Know
Step by Step
-
Remove visible hair from the drain
After each shower, pull out any hair visible at the drain opening. If you use a drain screen, empty it into the trash. This takes literally 5 seconds and prevents the majority of clogs.
-
Use a drain snake for slow drains
Push the snake into the drain and rotate it. The barbs or hook catch the hair mass. Pull slowly -- the clog will come out as a nasty, satisfying mass of hair and soap. Repeat until the snake comes out clean. Run hot water for a minute to flush.
-
Monthly preventive flush
Pour half a cup of baking soda down the drain, followed by half a cup of vinegar. Cover the drain and let it fizz for 15 minutes. Flush with a kettle of boiling water. This dissolves soap scum and organic buildup that hasn't hardened yet.
-
Remove and clean the drain assembly
Pop-up and push-pull tub drains can be removed by hand or with a screwdriver. The pivot mechanism underneath collects a shocking amount of hair and gunk. Clean it off, reinstall, and you'll notice an immediate improvement in drain speed.
Pro Tips
- A TubShroom or similar drain hair catcher pays for itself in prevented plumber visits within a month.
- Enzyme drain maintainers (like Bio-Clean) break down organic buildup over time and are safe for all pipe types.
- If you have long hair, brush before showering. This removes loose hairs before they go down the drain.
- Never pour chemical drain cleaners into a shower drain as regular maintenance -- they damage pipe joints, especially on older metal drains.
Mistakes to Avoid
- Not using a drain screen at all -- the most preventable cause of shower clogs.
- Pouring chemical drain cleaner down a slow drain repeatedly instead of snaking it. The clog is physical -- chemicals don't dissolve a hair mass effectively.
- Ignoring a slow drain until it's completely blocked.
- Forcing a drain snake too aggressively, which can damage the P-trap or scratch the inside of PVC pipes.
When to Call a Pro
If a drain snake doesn't reach the clog, or if the clog keeps returning within weeks despite clearing, the blockage is deeper in the drain line and needs professional snaking or camera inspection.
Bottom Line
Use a hair trap on every shower drain. Empty it after each shower. Snake slow drains before they become clogs. Monthly baking soda and vinegar flush. That's it -- the entire routine costs $5 in supplies and prevents $150-$300 plumber visits.
