Let’s begin by understanding why bathtub drains clog in the first place.

What Causes Bathtub Drains to Clog?

Understanding the root cause of a clogged drain helps not only in removing the current blockage but also in preventing future issues.

Hair Accumulation

Hair is the primary culprit in most tub drain clogged cases. As strands go down the drain, they form mats that trap soap scum and lint, quickly forming a dense blockage.

Soap and Shampoo Residue

Body wash and soap scum can harden inside the drain pipe, especially when mixed with mineral-rich hard water. This sticky buildup narrows the drain's opening over time.

Hard Water Deposits

In many households, especially those without a water softener, hard water minerals like calcium and magnesium can form crusty buildup along the pipe walls. These deposits reduce the drain’s internal diameter and restrict flow.

Foreign Objects

Small items like jewelry, rubber bands, cotton swabs, or even bath toys can fall into the drain and become stuck in the P-trap. These act as physical barriers and can be difficult to remove without a drain snake.

Laundry Debris

Those who use their bathtub for hand washing clothes may unintentionally allow fabric threads, lint, or even bits of clothing labels to go down the drain. This can lead to compounded clogs, especially when combined with soap residue.

Poor Drain Maintenance

Many people don’t realize their drain is clogged until water stops flowing. Without regular tub drain cleaning, gunk and residue silently build up until a full blockage forms.

Essential Tools for Snaking a Bathtub Drain

Having the right tools can make all the difference when attempting to snake tub drain systems effectively.

Drain Snake (Auger)

Use a manual or motorized drain snake with a ¼-inch cable. This size is ideal for navigating tub drain bends without damaging pipes. If you don’t own one, consider renting from a local hardware store.

Tool to Remove Bathtub Drain

You may need a bathtub drain removal tool or a screwdriver to access the overflow plate or drain stopper, which must be removed before snaking. Some models also require a tool to unscrew bathtub drain parts tightly fitted in place.

Rubber Gloves and Eye Protection

Cleaning drains involves mess, gunk, and sometimes foul odors. Gloves protect your hands from bacteria and sharp debris, while safety glasses prevent splashback.

Bucket and Absorbent Towels

Keep a bucket nearby to hold any removed debris or dirty water. Use towels to protect your tub surface and soak up spills during the process.

Flashlight

A bright flashlight lets you inspect the drain and overflow tube for hair clogs or visible obstructions before inserting the snake.

Plastic Hair Removal Tool (Optional)

Before using a snake, try a hair removal stick (like a plastic zip tool). It’s often the fastest way to remove a hair clog in tub drains if the obstruction is near the surface.

Water Source

You’ll need access to warm or hot water to flush the drain afterward. Hot water helps rinse loosened grime and tests whether the drain is flowing properly again.

How to Snake a Bathtub Drain: Step-by-Step Instructions

If you're ready to fix a clogged drain pipe bathtub, this section outlines exactly how to do it. These steps apply whether you're using a manual auger or a motorized drain snake.

Step 1 – Prep and Protect Your Bathtub

Before starting, lay a towel or thick drop cloth in the bottom of your tub to protect the surface. Snaking tools—especially metal cables—can leave scratches on acrylic or solid surface tubs. This is especially important if you own one of our premium AquateX or Legnox bathtubs.

Put on rubber gloves, grab your flashlight, and ensure your tools are ready.

Step 2 – Remove the Drain Stopper or Overflow Plate

Most bathtub drains are best snaked through the overflow drain instead of the main floor drain.

Locate the overflow plate just below the tub spout.
Use a screwdriver or your tool to remove the bathtub drain parts and detach the cover.
If your stopper is connected via linkage, pull out the entire assembly carefully.
Check for hair or soap gunk. Often, you can unclog your bathtub drain with hair removal alone.

If the blockage isn’t at the surface, proceed to the next step.

Step 3 – Insert and Feed the Drain Snake

Feed the drain snake cable into the overflow opening slowly. Keep the first few feet of the cable straight and avoid letting it coil too early.

For manual snakes, crank the handle slowly while pushing.
If using a motorized model, engage the motor at low speed and continue feeding the snake.
As you work through the P-trap, you may feel resistance. This is typically where the clog lives.

Take your time. If the snake won’t go down the bathtub drain, don’t force it. Retract slightly, then feed again while rotating.

Step 4 – Break Up or Extract the Clog

Once resistance is met:

Rotate the snake to break apart the obstruction.
Pull it back a few inches to test whether you’ve snagged hair or gunk.
Slowly extract the cable, cleaning it with a rag or towel as you go.

You might find a combination of hair, soap scum, and fabric debris—especially if the bathtub has been used for laundry.

Repeat the feed/pull method a few times until you feel no more resistance.

Step 5 – Flush and Test the Drain

After removing the snake, run hot water through the overflow for at least 2–3 minutes.

This serves two purposes:

It tests whether the water drains freely.
It helps flush any loosened debris through the pipe.

Use a bucket to catch any backflow in case a partial clog remains. If needed, repeat the snaking process one more time.

How to Remove Hair and Soap Buildup in Tub Drains

In many cases, snaking a bathtub resolves the main clog, but additional cleaning helps prevent immediate recurrence.

Tip 1: Use a Plastic Hair Tool

Before or after snaking, insert a flexible hair removal tool (like Zip-It) into the floor drain. This grabs hair that may have clung to the upper part of the pipe or stopper linkage.

It’s one of the best ways to unclog tub drain issues caused by surface debris.

Tip 2: Flush with Boiling Water

Once hair is removed, pour boiling water directly down the floor drain or overflow hole to soften any remaining residue.

This is especially effective when dealing with shampoo buildup or waxy soap layers.

Tip 3: Use Baking Soda and Vinegar for a Natural Flush

Here’s how to clear a tub drain using household items:

Pour 1 cup of baking soda down the drain.
Follow with 1 cup of white vinegar.
Cover the opening with a stopper or towel to contain the fizz.
Wait 15 minutes, then flush with hot water.

This helps dissolve minor soap and mineral buildup and complements the snaking process.

Troubleshooting Hair Clogs: When the Drain Still Runs Slow

If the tub still drains slowly after snaking and flushing:

Check for hair lodged in the linkage rod or crossbars.
Reinsert the snake and rotate gently to capture any remaining mass.
Try inserting from both the overflow and the floor drain (if accessible).

Persistent issues may indicate a clog deeper in the system—possibly in a shared branch line—which we’ll address in a later section.

Common Problems When Snaking a Bathtub Drain

Even with the right tools and techniques, snaking doesn’t always go smoothly. Here are some of the most common problems homeowners face when attempting to snake a bathtub drain—and how to resolve them safely.

What If the Snake Won’t Go Down the Bathtub Drain?

This is one of the most frequent frustrations. If the snake won’t go down the bathtub drain, here’s what to check:

Are you inserting it through the right opening? Always snake through the overflow hole, not the floor drain. The overflow line offers a straight shot into the pipe, avoiding the tight curve of the P-trap.
Is the snake hitting a bend? Try rotating the cable slowly as you push. Most manual snakes require a combination of twisting and steady pressure to navigate curves.
Are you using the right snake size? A ¼-inch snake is ideal. Anything thicker may be too rigid for bathtub pipes, especially in older homes.

If the snake continues to resist, retract it completely, clean the cable, and feed it again with gentle pressure.

What If the Snake Gets Stuck?

A stuck snake can cause more damage than the clog itself if not handled correctly.

Don’t yank it. Pulling too hard may kink the cable or damage the pipe.
Reverse feed slightly. If you’re using a motorized snake, reverse the motor briefly while gently pulling the cable out.
Use lubrication. Pour warm water or dish soap into the overflow to help loosen any tight turns.

In rare cases, if the snake becomes lodged beyond recovery, it’s best to stop and call a professional plumber to avoid damaging the drain.

Can Snaking a Drain Damage Pipes?

Yes—if done incorrectly. Here are safety precautions to protect your plumbing:

Avoid power tools on delicate plumbing. If your home has older galvanized or thin PVC pipes, use a manual snake to reduce the risk of cracking or puncturing.
Don’t force the cable. Forcing the snake can cause the cable to turn sharply into a wall fitting or the vent line, which may result in a break or misdirection.
Limit the snake’s extension. You typically don’t need to go more than 3–6 feet into the tub drain. If you’ve gone 10+ feet, you may be feeding into the vent stack instead of the main line.

If you experience gurgling sounds, backup in other drains, or persistent slow drainage after snaking, the clog may be located deeper in the system.

Chemical-Free Alternatives to Snaking a Bathtub Drain

Snaking is often the best method for how to unclog a bathtub drain with a snake, but if you're hesitant or dealing with only a mild blockage, you can try these safer alternatives first.

1. Boiling Water Flush

For minor soap scum or grease-based clogs:

Boil a full pot of water.
Carefully pour it down the drain in stages.
Wait a few minutes between pours to allow each batch to break up grime.

This is most effective in bathtubs without much standing water.

2. Plunger Method

A standard plunger can sometimes unplug a bathtub drain if the clog is close to the surface.

Fill the tub with a few inches of water.
Cover the overflow drain with a damp towel or tape.
Place the plunger over the main drain opening and plunge forcefully for 30 seconds.

Repeat if needed. This creates enough pressure to dislodge soft clogs or shift trapped hair.

3. Baking Soda and Vinegar

This classic combination helps with smelly, slow drains caused by soap or organic residue.

Remove any standing water.
Pour 1 cup of baking soda into the drain.
Add 1 cup of vinegar.
Let the mixture foam and sit for 15 minutes.
Flush with hot water.

Avoid using this method if you’ve recently used a chemical drain cleaner, as the reactions can be dangerous.

When These Methods Don’t Work

If you’ve tried snaking, plunging, and flushing but the tub remains slow or clogged, you might be facing a deeper or more complex issue. Common signs include:

Water is backing up into other drains
Gurgling noises from the toilet or sink
Foul odors from the bathtub drain
The tub clog is returning within a few days

At this stage, calling a licensed plumber is advised. They can inspect the full system using a drain camera and professional-grade auger or hydro jet.

How to Prevent Bathtub Drains from Clogging Again

Once you’ve successfully cleared the blockage, regular maintenance is key to preventing the need to repeat the process. Whether you’re dealing with heavy use, hard water, or occasional fabric washing in the tub, these simple routines will help you avoid future clogs.

Install a Hair Catcher

One of the most effective preventive tools is a drain hair catcher. This low-cost insert sits above or inside your drain and traps hair before it enters the pipe.

Empty it weekly to prevent buildup.
Consider options with a finer mesh for better debris capture.

Flush the Drain Monthly

Once a month, flush the drain with a gallon of hot water to help melt away any early soap or conditioner residue. If you live in a hard water region, do this twice monthly to help prevent scale.

Use Enzyme-Based Drain Cleaners

Unlike chemical cleaners that may damage pipes over time, enzyme cleaners use bacteria to naturally break down organic matter like hair and oils. Use these monthly to maintain flow and eliminate odors.

Limit Oil-Based Bath Products

Bath bombs, oils, and heavy conditioners can contribute to residue buildup inside the drain. Consider using them sparingly or rinsing the tub with hot water afterward.

Use a Water Softener (If Applicable)

Hard water causes scale—calcium and magnesium deposits—that shrink your pipe diameter over time. If this is an issue in your area, install a water softening system to protect not only your bathtub drain but also your home’s entire plumbing system.

How to Wash Clothes in the Bathtub Without Clogging the Drain

Many homeowners and renters turn to the bathtub as a backup laundry space when a machine isn’t available, or for washing delicate items. While effective, improper laundry methods can contribute to clogs. Here’s how to do it safely.

Is It Safe to Wash Clothes in the Bathtub?

Yes—if done correctly. Bathtubs like Aquatica’s deep soaking models are designed to handle substantial water volume and are often used in compact homes without laundry machines.

That said, avoid letting fabric fibers, loose threads, or large pieces of soap flow directly into the drain.

What You'll Need

A small amount of gentle detergent, body wash, or even shampoo
Optional: a soft scrub board or gloves
Access to warm water
A hair catcher or mesh cover to prevent fiber buildup in the drain

Step-by-Step Guide to Hand-Washing Clothes in the Bathtub

Clean the Tub First: Ensure the tub is clean before washing clothes—especially after snaking or any recent drain maintenance.
Plug the Drain: Use a tight-fitting stopper. Fill the tub with warm water (not hot, to protect fabrics).
Add Detergent: A small amount is enough. You can use:
- Delicate laundry detergent
- Body wash (if mild)
- Shampoo (as a last resort)
Soak Clothes: Let garments soak for 10–15 minutes.
Agitate Gently: Swish the clothing with your hands or use a washboard. Avoid scrubbing directly over the drain.
Drain with Protection: Before draining the tub, install a mesh hair/fabric catcher to collect any lint or clothing threads.
Rinse & Dry: Refill with clean water to rinse. Wring out excess water and hang items to dry.

Best Practices

Avoid washing fuzzy or fraying garments (e.g., wool, towels).
Do not overload the tub.
Rinse the drain with hot water after every laundry session to prevent buildup.

Snaking a Bathtub Drain - Frequently Asked Questions

How Do You Snake a Bathtub Drain Properly?

To snake a bathtub drain properly, follow these steps:

Remove the overflow plate or tub stopper.
Insert a ¼-inch manual or motorized drain snake into the overflow opening.
Feed the cable slowly while rotating it clockwise.
Continue feeding until you reach the clog (usually within 3–5 feet).
Rotate to dislodge or pull the clog out.
Extract the snake, cleaning it as you go.
Flush the drain with hot water to ensure it’s clear.

What Is the Best Way to Unclog a Bathtub Drain?

The most effective method is using a drain snake, especially for stubborn hair or soap clogs. That said, if the blockage is minor, try:

A plastic hair removal tool
A plunger (with overflow covered)
A baking soda and vinegar flush
Pouring boiling water

But for deeper clogs—especially when the tub drain is clogged and slow—snaking remains the best solution.

Can You Snake a Tub Yourself?

Yes. With a little preparation, the right tools, and a careful approach, most homeowners can handle snaking a bathtub drain without professional help.

That said, if you experience:

Backflow from other drains
Gurgling sounds
A snake that won’t go down the drain
Strong odors

…it may indicate a larger plumbing issue. In that case, it’s best to contact a professional. For more complex issues, we recommend consulting with a plumber trained in residential drain systems.

What If the Snake Won’t Go Down the Bathtub Drain?

Try the following:

Snake through the overflow plate, not the floor drain.
Use a ¼-inch cable to navigate curves easily.
Rotate gently as you feed to help pass through bends.
Withdraw and reinsert slowly if you hit resistance.

Still stuck? It could mean you’ve reached the vent line or a T-joint. Re-position the cable or stop and assess.

How Far Should I Push the Snake?

Push the snake 3 to 6 feet into the drain. If you go farther without resistance, you may have missed the clog or entered a vent line. Most bathtub clogs reside within the first few feet of pipe, usually at or before the P-trap.

What Happens If I Use the Wrong Snake Size?

Using a snake that’s too large or stiff may:

Scratch your tub finish
Damage pipe joints
Fail to navigate turns

Stick with a ¼-inch cable auger for tubs. It offers enough flexibility to get through the trap without compromising strength.

Why Does My Tub Keep Clogging?

Recurring clogs are usually due to:

Hair buildup (if no drain screen is used)
Heavy conditioner, body oils, and bath products
Lack of monthly flushing or maintenance
Hard water scale
Laundry residue from frequent hand-washing in the tub

For preventive care, install a drain screen, flush with hot water weekly, and consider using enzyme-based cleaners or softeners if scale is present.

What Tools Do I Need to Snake a Bathtub Drain?

Here’s your essential checklist:

Drain snake (manual or powered)
Bathtub drain removal tool
Screwdriver (for stopper or overflow plate)
Work gloves & safety goggles
Bucket & towels
Flashlight
Optional: plastic hair removal stick

How to Get Hair Out of Drain in Tub?

If the clog is near the surface:

Use a plastic hair removal tool to hook and pull hair
Check the stopper crossbars—these often catch strands
Rinse with hot water after clearing

If hair is deeper, a drain snake is necessary.

Is It Safe to Use Chemical Drain Cleaners?

We don’t recommend using harsh chemical cleaners, especially in luxury tubs like those made from AquateX™ or EcoMarmor™. Over time, these chemicals can:

Erode pipes
Damage internal fittings
Degrade certain bathtub materials

Instead, try enzyme-based drain cleaners or natural solutions like baking soda and vinegar.

What’s the Best Way to Prevent Future Clogs?

Use a hair catcher
Rinse the tub with hot water weekly
Avoid excessive oils, bath bombs, and fabric threads
Perform monthly cleaning with enzyme solutions
Snake the drain every 6–12 months (as preventive care)

These simple routines will ensure your Aquatica bathtub stays clean, hygienic, and fully functional.

When Should You Call a Professional?

Most bathtub drain clogs can be resolved with a basic snake tub drain process. However, in certain situations, it’s safer, faster, and more cost-effective to call a licensed plumber.

Signs That Indicate You Need Professional Help

1. The Snake Doesn’t Reach or Remove the Clog

If you’ve used the snake properly, including through the overflow, and the drain is still clogged or only partially draining, the clog may be:

Deeper in the main sewer line
In a shared branch line
Misdiagnosed (e.g., collapsed pipe or vent blockage)

2. Water Is Backing Up into Other Fixtures

When running water in one drain causes backup in the sink, toilet, or shower, it typically means the clog is deeper than what a household snake can reach.

3. Recurring Clogs After Multiple Cleans

If you snake your tub, remove hair, flush the line—and the problem returns within days or weeks—this points to:

A bigger obstruction further down the line
A structural issue (e.g., offset or sagging pipe)
Poor slope or water flow design

4. Foul Odors or Gurgling Sounds

Persistent smells, bubbling, or gurgling sounds after using any drain may indicate sewer gas buildup or a venting issue.

5. You’re Uncomfortable Doing It Yourself

There’s no shame in getting expert support. If you're uncertain about how to fix a clogged bathroom tub, worried about damaging a high-end fixture, or just prefer professional hands—contact a licensed plumber.
