Every shower sends loose hair down the drain, and shampoo, conditioner, and soap give it something to stick to. The mat forms at the first bottleneck it finds — usually the stopper mechanism or the cross bars, called crosshairs, molded into the drain under the flange. It builds slowly. The water drains a little slower each week, until one day you're showering in ankle-deep water that takes ten minutes to leave.
The good news: that clog is almost never deep in the plumbing. It's right there at the top of the drain, within reach of a tool that costs a few dollars. The method is the same one used to unclog a shower drain, because a tub clog and a shower clog are the same wad of hair in a slightly different drain.
Gel and liquid cleaners are a poor match for this job. They pool on top of standing water and barely reach the mat, and hair is the thing they dissolve worst — most of their strength goes into the grease around it. They can damage tub finishes and old metal pipes, and if they fail, you're left fishing around in a tub of caustic water. Physical removal beats chemistry here: a hair mat comes out in one disgusting piece, and then the drain is genuinely clear instead of mostly clear.
Remove the stopper. Most tub stoppers come out by hand. A lift-and-turn or push-pull stopper unscrews counterclockwise once you hold the base still; a toe-touch stopper unscrews at the cap. If your tub has a trip lever on the overflow plate instead of a pop-up stopper, skip to step 2 — the plug in that design hangs on a linkage inside the drain, and it comes out from above.
On a trip-lever tub, pull the linkage. Unscrew the overflow plate and slowly draw the whole linkage assembly up and out. Don't be surprised by what comes with it: the hair mat often grows right on the linkage and the plug, and pulling it out can clear the drain in one move. Scrape it clean before it goes back in.
Clear what's hanging on the stopper. Hair wraps around the stopper post and the underside of the flange. Pull it off with gloved fingers or the pliers and drop it straight in the trash. This alone fixes more tub drains than you'd expect.
Fish the drain with the stick. Push the barbed stick down past the crosshairs, twist it a quarter turn, and draw it up slowly. The barbs grab the mat on the way out. Repeat, rotating the stick to a fresh angle each time, until it comes out clean. Work gently — the goal is to hook the clog, not to shove it down into the trap.
Test it. Put the stopper back loosely or leave it out, and run the water for two or three minutes. If it drains as fast as it comes in, you're done — reinstall everything and flush a minute of hot water down to rinse the line.
Plunge, if it's still slow. Fill the tub with a few inches of water. Press a wet rag firmly over the overflow opening — this seal is what makes plunging work — and set the cup plunger flat over the drain. Push and pull in strong strokes. On a tub drain, the pull does as much work as the push, dragging the clog back toward you.
Auger through the overflow, if you have to. Remove the overflow plate and feed the hand auger's cable down that opening. It gives you a straighter run at the trap than the drain itself. Crank clockwise as you feed, go slowly when you feel resistance, and reel the cable back out bringing the clog with it. Finish with a long hot-water flush.
| Method | What It Removes | Typical Cost |
|---|---|---|
| Drain stick | Hair at the stopper and crosshairs | A few dollars |
| Plunger (overflow sealed) | Soft clogs just past the trap | You probably own one |
| Hand auger via overflow | Compacted clogs in the first few feet | Commonly $15–$30 |
| Chemical cleaner | Grease, slowly — poor on hair | Not recommended here |
Pouring in a second bottle. When the first dose of cleaner fails, the clog isn't a chemistry problem — it's a hair problem. The second bottle just makes the water you're about to reach into more dangerous.
Forcing the stick or auger. Resistance means you've found the clog, not that you should push harder. Shoving can pack the mat deeper or push it past the trap into pipe you can't reach from above.
Plunging with the overflow open. Without a seal over the overflow, every stroke just moves air in and out of that opening. The drain feels nothing.
Tearing into the trap from below, first. Some tubs have an access panel behind them, and opening the trap is a legitimate last resort. But nine times out of ten the clog is reachable from above in minutes, without a bucket, a wrench, and a mess.
A hair catcher that sits over the drain costs a few dollars and stops the mat from ever forming — empty it after each shower and that's the whole maintenance routine. Once a month, pull the stopper and clear whatever has started to gather, and run the hottest water the tap makes for a minute to melt down soap film before it hardens. The same chemical-free habits that work for tubs apply all over the house; these ways to unclog a sink without harsh chemicals use the same logic at the bathroom sink.
Call when the problem stops being local. If the tub, the sink, and the toilet are all slow, or using one fixture makes another gurgle, the clog is in a shared line, not your tub. Same answer if you clear the drain properly and it's slow again within days, or if water backs up carrying a sewage smell. Those are main-line and venting problems, and they don't yield to a drain stick. Knowing roughly how much a plumber costs before you call keeps the conversation grounded.
Start at the stopper, not the store shelf. Pull it, clean it, fish the crosshairs with a drain stick, and test. That sequence clears the overwhelming majority of tub clogs in about 20 minutes for a few dollars — and once you see the size of the hair mat that comes out, you'll understand why no bottle of gel was ever going to dissolve it.
Each fixture has its own trap and drain arm before the pipes join up. A hair mat in the tub's drain slows only the tub. When several fixtures go slow at once, the clog sits past where they join — that's a different, bigger problem.
Not this clog. The fizzing makes it pleasant for freshening a drain that smells, but it won't dissolve a compacted mat of hair and soap. You need to pull the mat out physically. Save the baking soda for after the drain is clear.
First confirm the type — most toe-touch and lift-and-turn stoppers unscrew by hand once you grip the base. If it truly won't budge, a drain stick often slips past it at an angle and can still hook the mat. If that fails, go in through the overflow opening with an auger, or have a plumber remove a stopper that may be corroded in place.
Yes, with a hand-crank auger. Feed it through the overflow opening rather than the drain for a straighter path, crank gently, and never use a powered auger in a tub — the cable can whip and crack the finish or the pipe. Gentle and slow clears clogs; force just compacts them.
Gurgling means air is being pushed or pulled through the tub's trap because water elsewhere in the system can't vent or drain properly. That's a venting or shared-line issue, not a tub clog — it's one of the clearest signs to stop DIYing and call a plumber.
