Standing in ankle-deep, soapy water while taking a shower is a miserable way to start the day. A slow shower drain is one of the most common plumbing complaints, and it is almost always caused by the exact same two culprits: soap scum and hair.
The Short Answer: To prevent a slow shower drain, you must use a mesh hair catcher over the drain hole and switch from bar soap to liquid body wash. For ongoing maintenance, avoid harsh chemical drain cleaners (which destroy your septic system) and instead use a natural, enzyme-based treatment monthly to dissolve the sticky soap scum lining your pipes.
Let’s look at why your shower drain clogs so easily, how to clear it safely, and the simple habits that will keep it flowing freely.
The Perfect Storm: Hair and Soap Scum
Your shower drain is the perfect environment for a clog to form.
Every time you bathe, you shed hair. On its own, hair might eventually wash down the pipe. But when you add soap to the mix, you create a sticky, impenetrable barrier.
Most traditional bar soaps are made with animal fats or vegetable oils. When these fats mix with the minerals in hard water, they create a thick, waxy residue known as soap scum.
This soap scum coats the inside of your drain pipe. As hair washes down, it sticks to the scum. More soap scum then coats the hair, creating a tangled, sticky mass that slowly chokes off the flow of water.
Why Chemical Drain Cleaners Are Dangerous
When the water starts pooling around your feet, the easiest solution seems to be pouring a bottle of heavy-duty chemical drain cleaner down the drain.
If you have a septic system, this is a disastrous mistake.
Commercial drain cleaners (like Drano or Liquid-Plumr) use caustic chemicals like bleach and lye to burn through clogs. When these chemicals reach your septic tank, they instantly kill the beneficial bacteria your system relies on to break down solid waste. Without those bacteria, your tank will fill up rapidly, leading to a catastrophic and expensive drain field failure.
Furthermore, these chemicals generate intense heat that can warp or melt the PVC pipes under your shower, leading to hidden leaks inside your walls or floors.
Step 1: Physical Removal (The “Zip-It” Tool)
If your shower is already draining slowly, the first step is to physically remove the hair clog.
The best tool for this job is an inexpensive, flexible plastic drain snake (often called a “zip-it” tool). These cost a few dollars at any hardware store and have small, backward-facing barbs.
- 1. Remove the drain cover or stopper.
- 2. Slide the plastic snake down the drain as far as it will go.
- 3. Slowly pull it back up. The barbs will grab the hair and pull the entire clog out in one piece.
This is far safer and more effective than pouring chemicals down the drain.
Step 2: Change Your Shower Habits
Once the drain is clear, you can prevent future clogs with two simple changes:
- **Use a Hair Catcher:** Buy a simple silicone or metal mesh hair catcher that sits directly over the drain hole. This catches the hair before it ever enters the pipe. Simply wipe it clean after every shower.
- **Switch to Liquid Body Wash:** Liquid body washes and shower gels are formulated differently than bar soap. They do not contain the heavy fats that create sticky soap scum, meaning they rinse cleanly down the drain without leaving a residue for hair to cling to.
Step 3: Maintain with Natural Enzymes
Even with a hair catcher and liquid soap, microscopic amounts of organic matter, skin cells, and shaving cream will inevitably wash down the drain and coat the pipe walls.
To keep the pipes completely clear and odor-free, you must maintain them with a natural, enzyme-based drain treatment.
Products like a natural enzyme-based drain cleaner use natural bacteria to literally “digest” the organic biofilm lining your pipes. By pouring a small amount down the drain once a month before bed, the enzymes work overnight to break down the sticky residue.
Because it is 100% natural, it is completely safe for your plumbing. And when those enzymes eventually reach your septic tank, they actually help the system by adding more healthy bacteria to the ecosystem.
The Bottom Line
A slow shower drain is annoying, but fixing it shouldn’t cost you your septic system. By physically removing hair clogs, switching to liquid soap, using a hair catcher, and maintaining the pipes monthly with a natural enzyme product like a natural enzyme-based cleaner, you can keep your shower draining perfectly without ever using a drop of harsh chemicals.
