Being in a situation where the tub’s drain is releasing debris into the tub itself can be frustrating.
You are going to want to find out what is causing dirt to flow into the bathtub and what you can do about it. Having dirt in the tub after a bath is unacceptable and unsanitary.
Dirt can appear in the tub after a bath due to a sewer line clog. This sewer line connects to the shower and toilet drain in a bathroom. If there’s a clog, it can cause the sewage to creep back up the plumbing into the tub. To fix the issue, turn off the water source, check the vent pipe and snake the drain.
This is a real cause for concern as it might require professional assistance to fix the issue.
In some cases, the clog is so deep that it can only be accessed by a professional plumber. If that is the situation you’re dealing with, consult with a specialist as soon as you can.
Otherwise, the dirt will continue to back up into the bathtub as time goes on.
This guide will look at shedding light on what to do when there is dirt in the tub after a bath.

How To Fix Dirt In Tub After Bath
1. Turn Off The Water Supply
The main issue is going to be in the sewer line.
This means you have to find the connecting point between the plumbing fixtures in the bathroom, which is causing the sewage to come back up into the tub after a bath.
If that is the case, you can’t work on a solution until the water valve is off.
Do this first and make sure to drain the faucet of water before unscrewing anything or working on the drain.
This will ensure you can work peacefully without having to worry about water squirting everywhere as soon as you begin.

2. Access The Drain
If there is brown dirt after a bath, this means you have a clog in the drain.
When this is the case, the best course of action is to access the drain in the bathtub. This is going to offer a way into the connecting point between the sewer line and the bathtub itself.
To do this, you are going to want to take out the drain cover.
You can do this by unscrewing it and pulling out the drain cover. Make sure to keep the screws somewhere safe as you are going to need them later.
3. Snake The Drain To Unclog It
The next step is the most important one.
You are going to need a long drain snake that will allow you to go deeper into the plumbing.
Most clogs that are pushing dirt up into the bathtub will be deeper than the average clog.
This means you are going to need to keep snaking the drain until you are deeper into it. This is the only way to unclog a sewer line without having to call in a professional to do the job.

4. Call a Plumber (If Necessary)
This is a possible step you will have to take if the clog is far too deep into the sewer line.
This does happen when something else is caught in the sewer line such as external debris (i.e. leaves).
You have to be careful and make sure to call someone that can access the sewer line from the outside.
This is where a plumber comes into the equation as they are certified to work on the sewer line.
This can cost approximately $400-$600 depending on how extensive the clog is. It’s best to ask around for quotes when dealing with this emergency.
What Does It Mean When Sewage Backs Up In Bathtub?
If sewage backs up into the bathtub, this means there is a clog in the sewer line. This clog is causing the water to push back up into the bathtub with additional debris such as mud, feces, and/or a wide array of other elements.
It’s best to find a way to unclog the sewer line using a drain snake going through the bathtub.
