Removing a bathtub drain doesn’t have to be a plumber’s job. Whether you’re dealing with a clogged drain, replacing an old fixture, or preparing for a bathroom renovation, you can save money by tackling this task yourself.
Our comprehensive guide breaks down how to remove a bathtub drain, from identifying your drain type to troubleshooting potential challenges. With the right tools and our step-by-step instructions, you’ll have that drain out in no time, ready for your next plumbing project.
Understanding Your Bathtub Drain System
Understanding the components of your bathtub drain system will help you approach your DIY drain removal with confidence and avoid potential mistakes.
Bathtub Drain Components
A bathtub drain consists of several key components working together to control water flow and prevent clogs:
- Drain flange/cover: The visible part of the drain that screws onto the drain shoe and holds the stopper in place
- Drain stopper: Controls the flow of water in and out of the bathtub
- Drain shoe: The threaded part of the drain that fits into the drain opening in the bathtub and connects to the drain pipe
- Overflow plate: A decorative plate located near the top of the bathtub that covers the overflow opening—it helps prevent the bathtub from overflowing if the water level gets too high
- Overflow tube/elbow: A tube or elbow behind the overflow plate that connects to the drain pipe and allows excess water to drain out
- Drain pipe: The pipe that carries water from the bathtub to the main drain line
In addition to these parts, a trip-lever drain will have crossbars or a linkage that connects the trip lever behind the overflow plate to the drain stopper. A lift-and-turn drain will have a plunger or drain plug that sits inside the drain shoe and moves up or down to seal or open the drain.
Types of Bathtub Drains
Bathtub drains come in a variety of styles, with the main difference being the stopper mechanism.
- Lift-and-turn: Turn a knob on top of the flange to raise or lower the stopper
- Push-and-pull: Push the stopper down to close the drain and pull it up to open
- Trip lever: A lever behind or near the faucet controls a linkage mechanism that raises and lowers the stopper
- Toe-touch: A small lever activated by your toe opens and closes the drain
Each type requires a slightly different removal approach, which we’ll cover in detail later in this guide.
Common Drain Problems
Most homeowners don’t think about their bathtub drain unless something goes wrong. Understanding the most common drain problems and their potential causes will help you determine the best course of action.
- Clogs: Hair, soap scum, and other debris can accumulate in the drain pipe, restricting or completely blocking the flow of water
- Slow drainage: Even if the drain isn’t fully clogged, a partial blockage can leave you with a slow-draining tub
- Leaks: Leaks can occur at various points in the drain system, such as the drain flange, overflow plate, or pipe connections
- Stuck stopper: The drain stopper can become stuck due to debris buildup or mechanical issues, making it difficult to open or close the drain
- Broken linkage: If you have a trip-lever drain, the linkage connecting the trip lever to the stopper can break or become disconnected, preventing the stopper from operating properly.
- Worn-out parts: Over time, various components of the drain, such as the drain shoe, overflow tube, or stopper mechanism, can wear out or become damaged
- Overflow issues: If the overflow isn’t functioning properly, the bathtub can overflow even with the drain open
Some bathtub drain problems can be fixed with a simple cleaning or minor repair, such as clearing a clogged bathtub drain. Others—such as leaking drain shoes, broken linkage, or worn-out parts—require full drain removal and replacement.
Essential Tools for Removing a Bathtub Drain
Most bathtub drain removals require a few basic tools that you may already have in your toolbox. For more stubborn drains or specific types, you may need specialized tools to grip and turn the drain fittings. Here’s what you’ll need to tackle this project effectively:
- Flathead screwdriver
- Philips screwdrivers
- Needle-nose pliers
- Channel-lock pliers
- Adjustable wrench
- Drain wrench or drain key (optional)
- Tub drain extractor (optional)
- Drain removal pliers (optional)
Identifying Your Bathtub Stopper Type
Before you can remove your bathtub drain, you need to identify the type of stopper you’re dealing with. Here’s how to identify common bathtub drain types:
Pop-Up Stoppers
Pop-up stoppers are connected to a trip lever mechanism, often located behind the overflow plate. Look for a visible linkage or rocker arm extending through the drainpipe. If you see a trip lever, flip it to see if it opens and closes the drain.
Toe-Touch Stoppers
Toe-touch stoppers have a small cap or knob on top that can be pressed down to close the drain. They are designed for easy removal and replacement. To test whether you have a toe-touch stop, press down on the cap to see if the drain closes.
Push-Pull Stoppers
Push-pull stoppers have a knob on top that you push down to close and pull up to open. If your stopper has a knob, try pushing it down to see if it operates the stopper.
Lift-And-Turn Stoppers
Lift-and-turn stoppers are similar to push-pull models, but they require you to lift the knob slightly before turning to open or close. Try lifting and turning the knob to see if it operates the stopper.
Preparing for Drain Removal
Taking the time to set up your workspace will make drain removal easier. You should also take a few safety precautions. Here’s what to consider:
- Safety gear: Before starting, put on safety glasses and rubber gloves to protect yourself from debris, sharp edges, and cleaning chemicals.
- Ventilation: Ensure the bathroom is well-ventilated, especially if you plan to use any chemical solutions.
- Floor protection: Place a towel or drop cloth around the work area to protect the floor and catch any water or debris.
- Tidying: Remove any bath mats or items near the tub.
- Tool setup: Gather all your tools and place them within easy reach to avoid having to leave the area once you’ve started.
Step-By-Step Guide To Removing the Drain Stopper
Now that you’ve identified your stopper type and prepared your work area, it’s time to remove the drain stopper. Follow these steps based on your specific stopper type.
Removing Pop-Up Stoppers
- Flip the trip lever to the open position.
- Grasp the stopper and pull it straight up.
- If it resists, gently wiggle it while pulling to free it from the rocker arm.
- Once removed, you’ll see the rocker arm extending into the drain.
Removing Toe-Touch Stoppers
- Press the stopper to pop it into the open position.
- Grip the top of the stopper and turn it counterclockwise.
- Continue turning until the entire assembly comes free from the drain.
Removing Push-Pull Stoppers
- Pull the stopper into the open position.
- Hold the body of the stopper with one hand.
- Turn the knob on top counterclockwise with the other hand.
- If it’s tight, use pliers on the knob while holding the body with a towel for grip.
Removing Lift-And-Turn Stoppers
- Lift the stopper to the open position.
- Look for a set screw on the knob or stem.
- If present, remove the set screw with a screwdriver or hex key.
- Turn the entire stopper assembly counterclockwise to remove it.
Tackling the Drain Fitting
Once the stopper is removed, you’ll need to deal with the drain fitting itself. This part can be more challenging, especially if the fitting is old or corroded.
- Soften the plumber’s putty. Most drains are sealed with plumber’s putty that hardens over time. To make removal easier, soften the putty with a hairdryer or heat gun. Apply hot air directly into the drain for a few minutes until the putty becomes pliable.
- Use a drain wrench. If your drain fitting has crossbars, insert a drain wrench into the cross shape and turn counterclockwise to unscrew it. There are two ends to most drain wrenches—use the side that offers the best fit. After a few rotations, it should be loose enough to unscrew by hand.
- If necessary, use specialized tools. For drain fittings without crossbars, use a tub drain extractor designed to grip the inside walls of the fitting. Insert the extractor, expand it to grip the walls, and turn counterclockwise to remove the fitting. If you don’t have an extractor, needle-nose pliers can sometimes grip the edges of the drain to turn it.
Dealing with Stubborn or Corroded Drains
Sometimes, even with the right tools, a drain can be stubborn due to corrosion or years of buildup. In these cases, you may need to employ additional techniques to remove the drain.
First, try applying more heat. Use a hairdryer or heat gun to warm the area around the drain fitting. The heat will cause the metal to expand slightly, which can break the corrosion’s hold. Be careful not to overheat the tub surface, especially if it’s fiberglass or acrylic.
As a last resort before calling a professional, you can try a penetrating oil like WD-40 or a specialized rust penetrant. Apply the product around the edges of the drain fitting and let it sit for several hours or overnight. This can help loosen corrosion and make the drain easier to turn.
Cleaning and Inspecting the Drain Area
Once the drain is removed, take the opportunity to thoroughly clean the area. Remove any old putty, soap scum, or debris from the drain opening and surrounding surface. Inspect the area for any damage or signs of leaks that may need to be addressed before you install a new drain.
Installing a New Bathtub Drain
After successfully removing the old drain, you can install a new one. Be sure to select a replacement drain that matches the size and style of your bathtub and is compatible with your existing plumbing setup. Measure the drain opening carefully and consider the finish that will best complement your bathroom decor.
Follow these steps to install the new drain:
- Apply a ring of plumber’s putty around the underside of the new drain flange.
- Insert the drain into the opening and press firmly to create a seal.
- From below, attach the rubber gasket, friction ring, and locknut.
- Tighten the locknut with a wrench, being careful not to overtighten and crack the tub.
- Wipe away any excess putty that squeezes out around the drain.
Troubleshooting Common Issues During Drain Removal
During the drain removal process, you might encounter some challenges. Here are solutions to common problems:
- The drain spins freely without coming out: The crossbars may be broken. In this case, you’ll need to use a drain extractor or call a professional.
- The drain won’t budge even with heat and penetrating oil: You may need to cut the drain out. This is best left to a professional to avoid damaging the tub.
- You see water leaking from the overflow plate when removing the stopper: You may need to replace the gasket behind the plate.
When To Call a Professional Plumber for Drain Removal
While removing a bathtub drain is often a DIY-friendly task, there are situations where it’s best to call in a professional:
- The drain is severely corroded or damaged
- You encounter plumbing issues beyond the drain itself
- You’re uncomfortable working with the plumbing or lack the necessary tools
- The tub is old or delicate, and you’re worried about causing damage
A professional plumber can handle complex situations and make sure the job is done correctly, potentially saving you time and preventing costly mistakes.
Maintaining Your New Bathtub Drain
Once you’ve successfully removed and replaced your bathtub drain, proper maintenance can help prevent future issues and extend the life of your new drain. Here are a few tips to prevent future clogs and keep your drain functioning properly:
- Use a drain cover to catch hair and debris.
- Flush the drain weekly with hot water to prevent buildup.
- Clean the stopper mechanism regularly to prevent soap scum accumulation.
- Avoid using harsh chemical cleaners that can corrode the drain components.
- Wipe out excess hair after bathing.
- Avoid letting small objects go down the drain.
- Run water for a few seconds after each use to clear the pipes.
