If the causes are not dealt with properly and promptly, they can ultimately become problematic and lead to unsanitary conditions. You might be forced to replace the tub altogether in extreme cases of clogging.
Common Causes of Bathtub Drain Clogs
Bathtub clogs are actually preventable. Even though there are some that happen due to poor plumbing, a majority of the clogs are a result of your own doing. If you are wondering why your bathtub is clogged, it may surprise you that some of the simple things you do are a culprit. Knowing the various factors that may lead to a clogged bathroom will give you a better understanding of how to handle a clogged bathtub and how to stop it from clogging in future.
Here are some of the reasons that may cause your bathtub to clog.
Accumulated Hair Clogs
It’s natural for your hair to shed when taking a bath or a shower. With time the shed hair will stick to the walls of the drains of your bathtub. It will pile along the drain walls and eventually become a stumbling block for your tub water. As a result, the water will start draining slowly leading to a clog.
Sometimes it’s easy to remove the hair when it starts piling up, but if the hair is not removed straight away, it becomes an issue, and that’s when your bathtub drain becomes completely clogged.
Soap Residue/Scum Build-Up
Soap residue or scum is another leading cause for clogged bathtub drains. You might be mistaken to think that soap automatically dissolves in water and gets washed off. As you take a bath, the soap will leave scum that piles up in the drain walls, solidifies and eventually ends up clogging your bathtub drain.
The scum is deposited bits by bits on the walls of your drains, and along the way, it will trap other items such as dead skin coming from your body and hairs.
If the problem is taken care of at the start, your bathtub might not clog. However, if this soap scum goes unnoticed for a long period, it will pile and cause a severe clog.
Ideally, the only thing that should be going down the drains of your bathtub is water. However, as you take your bath, you might leave toiletries in your bathroom and find that the bathtub is full of foreign objects such as toothpaste caps, shampoo caps, children’s toys and many other small objects that can become a disaster in your bathtub drains.
Whether you are doing it internationally or not, the foreign items in your tub can easily cause a clog if they get stuck along the walls of the drains. Some of the foreign objects absorb water and enlarge and end up clogging the drains. It’s important to clean up after a bath and to avoid throwing items that can easily go down your bathtub’s drain and eventually clog it.
If you are using hard water in your home especially in your bathrooms, it’s possible that it’s causing your bathtub to clog. This can actually become a chronic problem if you have no access to fresh or filtered water.
Hard water tends to form sediments due to its mineral content. It will deposit the mineral sediments along the walls of your bathtub’s drainpipe, and if left uncleaned for a significant period, the mineral residue will eventually clog. The sediments will also slow down the flow of water, and in the process, they will trap and catch any other debris that could be passing through the drain and cause a clog. The problem becomes even worse when soap scum and hair attaches itself to hard water and mixes up with the mineral sediments.
If you have no means of having a fresh water supply for use in your home, you can invest in a water softening agent to solve this problem. Otherwise, if you keep using hard water, you are likely to keep on experiencing clogged bathtubs more often.
Another cause for a clogged bathtub drains is broken pipes. Water pipes can break due to a variety of reasons such as normal wear and tear, or extended plant roots near your home. Whichever the case, if your pipe is broken or has cracks, it becomes less efficient, and it’s more likely to cause a blockage.
A broken pipe can be hard to notice, and it might take you some time to realize that the clogged tub is a result of a broken pipe. However, if your drains seem clear of residues and foreign object, a damaged pipe could be the culprit, and it’s advisable to call a plumber to diagnose the problem.
Slow Water Flow
Slow water flow in your taps could be the reason why your bathtub and other drains are clogged. Low water pressure could mean that there is a build-up of sediments in the pipes. Therefore, the water flowing down your bathtub could be carrying dissolved minerals which are then deposited in your bathtub.
These minerals will pile up with time and eventually lead to a clog in your bathtub. Frequent cleaning can help prevent accumulation of these minerals, but if the problem persists, it would be best to call in a professional to help diagnose the cause of the mineral build up in your pipes.
Storms and Heavy Rains
If you have experienced heavy rains and storms that led to floods, it’s possible to experience clogs not just in your bathtub but even in other drains in other parts of your home. Generally, drains are not designed to accommodate this kind of weather, and so, water build-up is likely to happen due to the impact of heavy rains. If there is an excessive flow of water in the pipes and gutters, there will be a blockage that can make your drains to block including your bathtub drains.
A Clogged Sewer Line
Sometimes your bathtub could get clogged due to a clogged sewer line in your bathroom. Since the bathtub drain, sink drain and the toilet drain all drain to the same main sewer drain line, you are likely to experience clogs in your bathtub or toilet if there is a problem with the sewer line.
The best way to know that your sewer line is clogged or not draining water properly is when you flush the toilet, and instead of flushing, the water seems to come up in your tub. You will notice that the water goes down after some minutes. If the main drain pipe is partially blocked, your toilet cannot drain all its water as fast as it should and so, some of the water will divert and come up through your bathtub’s drain.
If this happens, just know that the main sewer line is clogged and within no time your bathtub drains will also clog. If the main sewer line is blocked, plunging won’t even help with the problem. This is because possible causes for a sewer line clog include things like roots, hard objects that have been flushed down the toilet or sometimes a huge accumulation of grease and scum. These are items that do not move easily, and the sewer line will require more than a plunge to solve the problem.
Poor Pipe Installation
If your drain pipes were poorly installed either by an unqualified person or through a DIY renovation project, they could lead to serious problems in your home. If badly installed, the drain pipes can get fractured, or they will not allow the right flow of water.
If you have incorrect water flow in your pipes or fractures, you start experiencing frequent clogs in your bathtub drains and other drains including sinks and toilets. If you are doing a renovation, it’s always recommended that you hire a licensed plumber to install your piping and drain system. This way, all the pipes will be installed properly and will allow the right flow of water hence no blockages due to the pipes.

|Toilet plunger together with a canister
|Korky 99-4A Beehive Max universal plunger
|Universal meaning it fits in any drain

Fill the bathtub with some water enough to allow you to submerge the plunger. The water is the one that gives the plunger the force to suction. Place the cup plunger carefully over the drain and make sure it covers the entire drain area. Push the plunger down with forceful strokes and then pull it up. Repeat the process for about six to ten plunges. You will keep seeing scum and dirt coming up to the surface as you plunge.
Once you are confident that most of the clog has been suctioned out, you can test the tub by filling it with water to see if it flows smoothly. If water flows down the drain without getting clogged, the exercise was a success. You can now replace the strainer or stopper. If the tub is still clogged, consider using another method.
Unclog Using Chemical Drain Cleaners
Another effective method of unclogging is by use of chemical drain cleaners especially if you have a severe blockage. The chemicals dissolve the scum, hair and any other dirt stuck in the drain walls. They are available in home improvement stores.

Do not attempt to use a different chemical drain cleaner if the one you had used failed to work. Mixing different chemicals in your drain can be dangerous, so instead just call for professional help.
Unclog Using Baking Soda and White Vinegar
This is another simple method that is effective and only requires simple products that could be available in your kitchen. For this method, you only need hot water, baking soda, and white vinegar. Vinegar and baking soda have a chemical reaction that dissolves the clog in your bathtub. However, this method works best for scum, grease, and organic clogs. It’s not ideal for hard objects clogging the tub such as shampoo caps or small toy parts.
You can purchase baking soda for about $1 a sachet from the food stores. Similarly, you can buy vinegar at an average cost of $5 to $130 depending on quantity and brand.
To use this method, remove the strainer or stopper. Clean and scrub it to remove the accumulated scum, hair, and dirt. Boil water using a kettle or a large pot and pour it on the drain. Sometimes the hot water can unclog a basic clog instantly. After pouring the hot water, you can run cold water on the tub to see if it has unclogged.
If the tub is still clogged, pour ¼ cup of baking soda in the drain and one cup of white vinegar. Allow the mixture to stay for about 15 to 20 minutes. In the meantime, boil water in a kettle or a large pot. Once the 15 or 20 minutes have elapsed, pour the water into the mixture. The vinegar and baking soda will react with water and dissolve the organic matter and scum in the drains. Afterward, test the tub by running cold water to see if it has unclogged. This method normally works for basic clogs and not the severe ones.
When You Should You Consider Calling a Plumber
Usually, bathtub clogs are easy to unclog using the methods described above. Before you decide to call a plumber, you can look around the tub by removing the strainer to see if the cause of the clog is organic matter such as hair or soap scum. Normally, most of the causes leading to bathtub clogs are minor, and they can be removed by using a plunger.
However, if the DIY remedies seem not to be working, and the blockage goes on to affect other plumbing fixtures such as sinks and toilets, you probably have a major clog in your main sewer line. As mentioned at the beginning of this guide, a clogged sewer line is a big issue that cannot be resolved by plunging. It can actually cause severe flooding if you continue using plumbing fixtures in your home and running water in them.
Therefore, if you establish that the problem of the clog is beyond the soap scum and hair, you should discontinue using your water supply in your home and call in a professional plumber immediately to address the issue.
Cost of handling mainline blockages will be added on top the minimum charge fee charged by plumbers. The plumber can clear the clogs through the drain vent on the roof, or, clear it from outside or pull a toilet. If the plumber unclogs the mainline from outside, you will be charged about $185 on top of the service charge. If they unclog the mainline through a drain vent, expect to spend about $273 for a one-story roof. If they clear the main line by pulling the toilet you will spend an average of $400.
Sometimes the blockage might be as a result of corroded pipes. If the drain pipes have corroded from the inside, the space for passing water will become too narrow limiting the amount of water passing through. If this happens to be the case with your pipes, a plumber will have to replace the pipes. Expect to spend an average cost of about $250 on replacement of pipes. If the whole home’s piping is corroded, you will spend about $740 to replace all the damaged pipes in your entire house.
