There is nothing quite as unpleasant as taking a shower and realizing that the water is rising around your ankles. Instead of a refreshing start to the day, you are standing in a pool of soapy, lukewarm backwash. A slow-draining shower is more than just a nuisance; it creates a breeding ground for bacteria, mold, and unpleasant odors. If you are searching for quick fixes for a slow-draining shower, put down the phone and don’t call the plumber yet. The best direct answer is to mechanically remove the hair blockage using a “zip-it” tool or a bent wire hanger, followed by a chemical-free flush using baking soda and vinegar. In this guide, I will show you how to pull out the gunk and restore your drain’s flow in less than 20 minutes using items you already have at home.
As a Life Solutions expert, I have dealt with this specific problem in every apartment and house I have lived in. The shower drain is a unique beast. Unlike the kitchen sink, which battles grease, the shower battles hair and soap scum. These two combine to form a reinforced net that catches everything. Over the last four years at Preposts.com, I have mastered the art of “drain surgery.” It is not glamorous, but fixing it yourself saves you the $150 plumber visit fee. Today, we are going to roll up our sleeves and get that water swirling again.

The Anatomy of the Clog: Why Is It Happening?
To fix the problem effectively, you need to understand what is happening in the P-trap (the U-shaped pipe under the floor). A slow drain is rarely caused by a solid object. It is caused by the “Hair Monster.”
Here is the cycle:
1. You shed hair in the shower.
2. The hair catches on the cross-hairs of the drain cover or the screw inside the pipe.
3. Soap scum (which is sticky) binds the hair strands together.
4. This creates a net that catches skin flakes and dirt, narrowing the pipe diameter until water can barely pass.
Because the clog is organic and tangled, chemical cleaners often fail to dissolve it completely. You have to physically break the net.
Method 1: The “Wire Hanger” Hook (The Most Effective Fix)
If you have long hair or live with someone who does, this is your primary weapon. It is gross, but it works instantly. We are essentially going fishing for hair.
What You Need
- A wire coat hanger (or a cheap plastic “Zip-It” tool from the hardware store)
- Needle-nose pliers
- Rubber gloves (Non-negotiable)
- A plastic bag for trash
The Process
1. Prepare the Hook: Straighten out the wire coat hanger. Use your pliers to make a small, tight hook at one end. The hook needs to be small enough to fit through the holes in your drain cover.
2. The Insert: Push the wire down the drain. You might feel resistance. Try to slide it past the initial cross-bar.
3. The Twist and Pull: Twist the wire to snag the hair clump. Pull it up slowly. You will likely pull up a grey, slimy mass of hair. Dispose of it in the plastic bag immediately (do not wash it back down!).
4. Repeat: Keep going until the hook comes back clean. The texture of wet, soapy hair can be incredibly stubborn. It is a similar sensation to the patience required when learning how to remove gum from hair—you have to tease the mess out gently without breaking it off, or you lose the “grip” on the clog.
Method 2: The Boiling Water Flush (For Soap Scum)
Once you have removed the physical hair, you need to deal with the sludge. Soap scum is made of animal fat or vegetable oil mixed with minerals. Heat melts it.
The Technique:
Boil a full kettle of water. Pour it slowly and directly down the drain. Do not pour it all at once; let the heat work on the pipe walls. This melts the greasy residue that was holding the hair in place.
Note: If you have plastic (PVC) pipes, let the water cool for a minute so it is hot (150°F) but not actively rolling boiling, to prevent softening the pipe glue.
Method 3: Baking Soda and Vinegar (The Volcano)
We use this combination for almost everything because it works. The fizzing reaction expands, filling the pipe and scouring the walls. This is the exact same chemistry we detailed in our guide on how to unclog a sink with baking soda. The principles of expanding gas and neutralizing acids apply perfectly to shower drains too.
Step-by-Step
1. The Base: Pour 1/2 cup of dry baking soda down the drain. Try to get it into the holes, not just around them.
2. The Acid: Pour 1/2 cup of white vinegar down after it. Cover the drain with a wet washcloth immediately to trap the fizz inside the pipe.
3. The Wait: Wait 20 minutes. You might hear gurgling.
4. The Rinse: Flush with another kettle of hot water. This clears out the loosened debris.
Method 4: The Plunger (Hydraulic Pressure)
If the drain is still slow, the clog might be deeper in the P-trap. You need to force it through.
1. Wet conditions: You need standing water for a plunger to work. If the shower is dry, run the water until there is about an inch covering the drain.
2. The Seal: Place the rubber cup of the plunger over the drain. If you have an overflow drain (like in a bathtub/shower combo), you must block the overflow hole with a wet rag, otherwise, the air pressure will just escape there.
3. The Pump: Pump vigorously up and down 10 to 15 times. You want to push water, not air, into the pipe.
4. The Release: Pull up sharply. The water should drain rapidly with a “whoosh” sound.
Method 5: Deep Cleaning the Drain Cover
Sometimes the problem is the cover itself. Over time, the underside of the drain cover gets coated in a thick, hard layer of mineral deposits and soap scum, effectively closing the holes.
1. Unscrew: You will likely need a screwdriver to remove the single screw holding the cover.
Troubleshooting: If the screw is stripped or stuck due to corrosion, don’t force it. Refer to my guide on natural ways to remove rust from tools. Applying a little vinegar or oil to the screw head can loosen the rust bond, allowing you to open the drain without stripping the head.
2. Scrub: Once the cover is off, soak it in vinegar. Use an old toothbrush to scrub away the slime. If the gunk is particularly sticky and stubborn (like old conditioner buildup), you can use the cleaning techniques found in how to remove old sticky oil stains from kitchen tiles without chemicals. The baking soda paste method works wonders on chrome drain covers too.
Method 6: The “Wet/Dry Vac” Vacuum
If you own a Shop-Vac (Wet/Dry vacuum), you have a powerful plumbing tool. Set the vacuum to “liquids” mode. Place the hose over the drain (you may need to wrap a wet rag around it to create a seal) and turn it on. It can often suck the hair clog straight up and out of the drain in one second. It is the reverse of plunging.
Prevention: Stop It Before It Starts
You cleared the drain. Now, how do we ensure you never have to do this again?
1. Install a Hair Catcher
This is the best $5 you will ever spend. Buy a “TubShroom” or a mesh screen that sits on top of or inside the drain. It catches the hair before it enters the P-trap. Clean it after every shower.
2. The Weekly Maintenance Flush
Do not wait for the drain to slow down. Once a week, dump a bucket of hot water down the drain.
Eco-Tip: You don’t need to waste fresh drinking water for this. If you have an RO filter in your kitchen, collect the reject water. We discuss this extensively in how to reuse RO waste water effectively. Using 10 liters of “waste” water to flush your shower drain is a perfect, sustainable maintenance habit.
3. Brush Before You Wash
Brush your hair before you get in the shower. This removes the loose strands and puts them in your hairbrush (and then the trash) instead of down the drain.
What NOT To Do
Avoid Chemical Drain Cleaners (Drano/Liquid Plumr)
I cannot stress this enough.
1. Damage: The heat generated by these chemicals can melt plastic pipes and corrode old metal ones.
2. Health: The fumes are toxic.
3. Cost: They are expensive.
4. Ineffectiveness: They often burn a small hole through the hair clog without removing it, meaning the drain slows down again in two days.
Do Not Use a Drill Snake without Experience
If you buy a mechanical metal snake, be careful. If you push too hard, you can crack the P-trap under the tub, leading to a leak that destroys the ceiling below.
Frequently Asked Questions
Why does my shower drain smell like rotten eggs?
That is sewer gas or bacteria growing on the hair ball. The baking soda and vinegar method will kill the bacteria and neutralize the odor. Follow it up with a few drops of essential oil (like tea tree or eucalyptus).
Can I use salt to unclog the drain?
Yes, salt adds abrasion. Mix 1/2 cup salt with 1/2 cup baking soda and pour it down. Let it sit overnight. The salt absorbs water from the clog, shrinking it.
My drain is still slow after all these steps. What now?
If you have snaked it, plunged it, and flushed it, the clog might be much further down the main line, or your vent pipe (on the roof) might be blocked. At this point, it is time to call a professional plumber.
Conclusion
A slow-draining shower is a symptom of maintenance neglect, but it is easily curable. The combination of mechanical removal (the wire hanger) and chemical cleaning (baking soda/vinegar) is a one-two punch that defeats almost any bathroom clog.
By taking 20 minutes to clear the pipe today, and installing a cheap hair catcher for tomorrow, you can ensure that your morning shower remains the relaxing sanctuary it is supposed to be. No more standing in puddles—just clean, flowing water.
