Why Is My Shower or Bathtub Draining Slowly?
Standing in ankle-deep water by the end of a shower? A slow tub or shower drain almost always traces to one culprit. Here's how to tell a simple hair clog from a deeper problem, what to try yourself, and when to call a plumber in the OKC metro.
You finish a shower and realize you’ve been standing in a pool of water that’s inching up your ankles. Or the tub takes twenty minutes to empty after a bath. A slow-draining shower or bathtub is one of the most common plumbing complaints we hear from homeowners around the Oklahoma City metro — and it climbs every summer, when the kids are home, everyone’s showering off sunscreen and lake water, and there’s simply more traffic through the bathroom than the rest of the year.
The good news: most slow shower drains have the same cause, and you can often clear them yourself in a few minutes. The trick is knowing when it’s a simple hair clog and when the slow drain is telling you something bigger.
What’s actually clogging your shower drain
Nine times out of ten, a slow tub or shower drain comes down to one thing: hair, bound together with soap scum and body oil.
Here’s how it builds. Hair washes down and snags on the drain’s crossbars or the stopper mechanism just below the opening. Soap residue and the oils rinsed off your skin coat that hair and act like glue. Then Oklahoma’s hard water does its part — the minerals in our water leave a scale that stiffens the whole tangle into a dense mat. Water still gets through, but slower and slower as the mass grows, until you’re standing in it.
Because this clog forms so close to the surface, it’s usually within reach — which is exactly why so many slow shower drains are a DIY fix.
Try this before you call anyone
Work through these in order. Most slow drains give up somewhere in the first three steps.
1. Pull and clear the stopper. Bathtubs and showers use a few different stopper styles — a lift-and-turn or push-pull knob, a toe-touch, or a lever-operated trip mechanism. Most unthread or lift straight out once you’ve opened them. You’ll often find a wad of hair wrapped around the stopper’s base the moment you pull it. Clean it off and set it aside.
2. Fish out the hair. With the stopper out, use a plastic drain-cleaning strip — the flexible barbed tool sold cheaply at any hardware store — or a piece of stiff wire bent into a small hook. Push it down past the crossbars, twist, and pull. Do it a few times. It’s genuinely a little gross, but this single step clears the large majority of slow shower drains.
3. Flush with hot water. Once the hair’s out, run the hottest tap water for a minute or two to melt and wash away the soap film left behind. A kettle of near-boiling water poured slowly down the drain works well too (for metal and modern PVC drains — go easy on very old or fragile pipes).
4. Plunge it. If it’s still sluggish, a cup plunger can shift a clog that’s a little farther down. Cover the overflow opening (the plate up on the tub wall) with a wet rag first so the plunger can build suction, add enough water to cover the plunger cup, and work it firmly a dozen times.
What we’d steer you away from is reaching straight for a bottle of chemical drain cleaner. On a packed hair clog it often just sits there against the blockage without dissolving it, and repeated use is hard on older galvanized and cast-iron pipes common in the metro’s established neighborhoods. If a plunger and a hand tool won’t clear it, the problem is past the point where more chemicals will help.
When it’s not just the shower
Everything above assumes the slow drain is a local clog in that one fixture. Here’s the signal that changes the story: pay attention to whether anything else is acting up at the same time.
If the shower drains slowly and the toilet gurgles when you run water, or the tub backs up when the washing machine drains, or bathroom sinks and the shower are all slow together — that’s not a hair clog near the surface. That’s a partial blockage deeper in the drain line or the main sewer line serving the whole house, and clearing the shower stopper won’t touch it.
Deeper blockages in this area usually trace to one of a few things:
- Buildup in a branch drain where grease, soap, and debris have narrowed the pipe over years.
- A main-line issue — tree roots working into the sewer line, a low spot (belly) in the pipe collecting waste, or aging pipe that’s partially collapsed. This is common with mature trees and older clay or cast-iron sewer lines around Edmond and central OKC.
The reason this matters: a main-line blockage that starts as a slow shower drain can end as sewage backing up into the lowest fixtures in the house. That’s the point where a nuisance becomes a mess and an expense. Catching it while it’s still “just a slow drain” is the whole game.
When the problem is deeper than the fixture, the right tool isn’t a plunger — it’s a camera inspection to see exactly what’s going on inside the line, followed by professional drain cleaning or hydro jetting to scour the pipe back to full diameter rather than just poking a hole through the clog.
Keeping it from coming back
A few habits keep shower and tub drains flowing:
- Use a hair catcher — a simple silicone or mesh screen over the drain — and empty it regularly. This one cheap item prevents most slow-drain calls we get.
- Run hot water down the drain for a minute after showers now and then to keep soap film from building.
- If your home is on hard water (most of the metro is), a water softener slows the scale buildup that stiffens clogs and coats the inside of your pipes over time.
- Don’t rinse anything greasy or waxy — melted bar soap chunks, hair-removal wax, heavy conditioners — down a shower drain if you can help it.
The bottom line
A slow shower or bathtub drain is usually a hair-and-soap clog sitting right below the opening, and pulling the stopper and fishing it out clears it most of the time — no chemicals, no plumber needed. The moment to pick up the phone is when the fix won’t hold, when the water won’t clear at all, or when the slow drain comes with gurgling toilets or other slow drains around the house. That last one is your early warning of a main-line problem, and it’s far cheaper to handle before it backs up.

Frequently asked questions
- What causes a shower to drain slowly?
- The overwhelming majority of slow shower and tub drains are a hair-and-soap clog just below the drain opening. Hair catches on the crossbars or stopper, soap scum and body oil glue it together, and Oklahoma's hard-water scale stiffens the whole mass until water can barely get past. If several drains in the house are slow at the same time, though, the problem is deeper in the main line, not in the shower itself.
- Can I unclog a slow shower drain myself?
- Often, yes. Pull the stopper or strainer, fish out the hair with a plastic drain-cleaning tool or bent wire, and flush with hot water. That clears most slow shower drains. Skip liquid chemical drain cleaners — they sit against the clog, can damage older pipes, and rarely dissolve a packed hair mass. If it keeps coming back or won't clear at all, it's time for a pro.
- Is a slow drain a plumbing emergency?
- A single slow shower drain isn't an emergency — it's routine maintenance you can usually schedule. But if the water backs up when you flush a toilet or run the washer, or if more than one fixture is draining slowly at once, that points to a main-line blockage that can turn into a sewage backup. That's worth calling about promptly.
