We’ve all been there. You’re looking forward to a nice hot shower after a brutal day, and what happens? The water starts pooling around your feet. Great. Just great. Nothing kills the mood quite like standing in a puddle of soapy water that refuses to go down the drain.

I’ve been dealing with stubborn bathtub drains for over fifteen years now, and let me tell you—they’re some of the most frustrating plumbing problems homeowners face. But here’s the thing: most of them can be fixed without calling in the cavalry. You need to know what you’re doing and when to admit defeat.

What Makes a Stubborn Bathtub Drain So… Stubborn?

Before we discuss solutions, let’s consider why bathtub drains get clogged in the first place. It’s a perfect storm of nastiness.
Hair is the main culprit—and I’m not just talking about the obvious strands you can see. Tiny hair fragments mix with soap residue, creating these gnarly clumps that stick to pipe walls. Then you add body oils, dead skin cells (yeah, I know, gross), and chunks of soap or shampoo that didn’t dissolve properly.

The real problem with a stubborn bathtub drain is that it develops slowly. You might notice water draining a little slower each week, but you ignore it because it’s still draining—until one day, it’s not.

Sometimes the blockage is right at the surface where you can reach it. Other times? It’s way down in the pipes, laughing at your pathetic attempts to clear it with a coat hanger.

My Go-To Method for Tackling That Stubborn Bathtub Drain

Over the years, I’ve developed a system that works 80% of the time. The key is being methodical—don’t just randomly try things and hope for the best.

Start With the Obvious StuffWhy Does My Ground Fault Outlet Keep Tripping?

First things first, remove whatever’s covering your drain. It could be a stopper, a strainer, or one of those fancy pop-up assemblies.

You’d be amazed at what collects around these things. I once pulled out what looked like a small animal, but it turned out to be six months’ worth of hair wound around the stopper mechanism. The homeowner nearly passed out. Clean everything off thoroughly. Sometimes that’s all it takes to get your stubborn bathtub drain flowing again.

The Zip-It Tool Is Your Friend

If you don’t own one of these little plastic drain snakes, buy one. Now. They cost like three bucks and they’re absolute game-changers.

These things look pretty basic—just a long plastic strip with little barbs on the sides—but they work wonders on hair clogs. Push it down slowly, twist it around, then gently pull up. What comes up will probably make you question your life choices, but hey, at least your drain will work. I’ve seen people pull up hairballs the size of hamsters with these things. It’s disgusting but oddly satisfying.

Hot Water: The Underrated Hero

Here’s something most people don’t think about: really hot water can dissolve a lot of the soap scum and grease that’s holding everything together in your stubborn bathtub drain.

Boil a big pot of water—and I mean actually boiling, not just hot from the tap. Pour it down slowly in two or three stages. The first pour might not do much, but sometimes that second or third round breaks everything loose.

Just be careful if you have PVC pipes. Boiling water won’t damage them, but it’s not great for them either. Stick to hot tap water if you’re not sure what kind of pipes you have.

When Things Get Serious

If the basic approach doesn’t work, it’s time to bring out the bigger guns. This is where dealing with a stubborn bathtub drain becomes less about finesse and more about persistence.

Plunging Isn’t Just for Toilets

I can’t tell you how many people have never tried plunging their bathtub drain. They think plungers are only for toilets, but that’s missing out on a powerful tool.

You need a flat-cup plunger—not the flange type you’d use on a toilet. Fill the tub with enough water to cover the plunger cup, then go at it with short, sharp plunges. Don’t go crazy with it, just steady pressure.

Sometimes you’ll hear this satisfying “glub” sound, and suddenly water starts swirling down like it should. Other times, you’ll pull up chunks of stuff that’s been living in your pipes for months.

Break Out the Real Snake

If you’re still dealing with a stubborn bathtub drain after all that, it’s time for a proper drain auger. Not one of those flimsy plastic things—I’m talking about a real snake with a crank handle.

Feed it down slowly, and when you hit resistance, that’s probably your clog. Twist the handle and push forward gently. Don’t force it—you can damage your pipes if you get too aggressive. Work it back and forth until you feel it break through.
Pull it back out slowly. What comes up might be horrifying, but at least it’s out of your pipes now.

Red Flags: When to Stop and Call Someone

Look, I’m all for DIY solutions, but there comes a point where you need to know when you’re in over your head. A stubborn bathtub drain can sometimes be a symptom of bigger problems.

  • If water backs up into other fixtures when you run the bathtub, that’s a sign of a main line issue. Not a DIY job.
  • If you smell sewer gas coming from the drain, stop what you’re doing. That could indicate a broken seal or damaged pipe.
  • And here’s a big one, if you’ve been using chemical drain cleaners and they’re not working, do NOT keep pouring more down. You might create a dangerous situation, and you definitely don’t want to stick your hand or tools into a drain full of caustic chemicals.

The Chemical Cleaner Debate

Speaking of chemical cleaners—I know they’re tempting. They promise easy solutions to your stubborn bathtub drainproblems. Just pour and wait, right?

Wrong. Most of them are terrible for your pipes and the environment. They rarely work on serious clogs, and they can make the problem worse by partially dissolving things and creating an even stickier mess.

I’ve seen pipes damaged by years of chemical cleaner use. The stuff eats away at metal and can soften PVC joints. Not worth it.

When I show up to deal with a stubborn bathtub drain, I’m bringing tools that most homeowners don’t have access to. We’re talking about motorized augers that can punch through just about anything.

But more importantly, I can diagnose what’s really going on. Is it just a surface clog, or is there something structural happening? Are the pipes properly sloped? Is there a bellied section where debris collects?

Sometimes we’ll run a camera through the line to see what we’re dealing with. Tree roots, collapsed pipes, major grease buildup—there are things that no amount of DIY effort is going to fix.

Preventing Future Stubborn Bathtub Drain Issues

The best way to deal with a stubborn bathtub drain is to prevent it from happening in the first place. Revolutionary concept, I know. Get a good drain screen and actually use it. Clean it out regularly—like every week, not every month. Run hot water after every shower to keep soap residue from building up.

Here’s something most people don’t think about, brush your hair before you shower, not during. Sounds silly, but it keeps loose hair from going down the drain in the first place.

And for the love of all that’s holy, don’t use your bathtub drain as a garbage disposal. I’ve pulled out chunks of soap, bottle caps, toys, and things I can’t even identify. Just because it fits down the drain doesn’t mean it should go there.

The Bottom Line on Stubborn Bathtub Drains

Most drain clogs are totally manageable with the right approach and a little patience. Start simple, work your way up to more aggressive methods, and know when to call for backup.

A stubborn bathtub drain doesn’t have to ruin your day or your budget. With the right tools and techniques, you can usually get things flowing again without too much drama.

But remember, if you’re not comfortable with any of these methods, or if nothing seems to work, there’s no shame in calling a professional. We’ve seen it all, and we won’t judge you for that horrifying hairball we pull out of your pipes. Trust me, we’ve seen worse.
