Do bath bombs stain tubs?

The last thing that you want to be worrying about when you’re getting a relaxing bath is that your favorite bath bomb may be staining your tub. But is this the case, can bath bombs stain your bathtub?

There have been noted cases of people’s bathtubs getting stained when using bath bombs in the water. However, it must be said that the chance of this happening is very low as bath bombs are designed to be used in the tub.

Let’s now have a look at some of the reasons why bath bombs may stain your tub.


This is the most common reason for bath bombs to cause staining. Not only do bath bombs fizz and bubble they also add lots of color to the water. When you use a bath bomb that has lots of color in it, there is a chance that this color will bleed into the tub.

This is why it’s important to choose a bath bomb that doesn’t have too much coloring in it.


Another reason why bath bombs may cause staining is because of the oils that are used in them. These oils can sometimes seep into the pores of the tub and cause staining. The oils also allow the coloring used in the bath bomb to bind to the surface of your tub.

To prevent this from happening, try to choose a bath bomb that doesn’t have too many oils in it. You can also try to avoid using bath bombs that contain citrus oils, as these are known to cause staining.

Why do bath bombs stain tubs?

As I mentioned earlier it is quite rare for a bath bomb to stain your stub, however, some factors will make it more likely to stain.

If your bathtub is quite old you can find that the protective coating on its surface or enamel may have broken down over time. This can be caused by harsh cleaning agents and chemicals.

Once this protective coating has started to break down it allows the softer and slightly more porous material behind it to soak up some of the colors of the bath bomb. If this is the case it will be very hard to remove the staining that has occurred.

Not all stains are stains.

Quite often when you use a bath bomb you will notice that once you have pulled the plug and drained the water there will be a colored line where the water level once was.

This at first glance may look like your bath bomb has stained your tub but it is actually just like a normal “soap scum” line. The oil and color from the bath bomb stick to your tub where the water level once was.

A simple wipe-down after you have had your bath will clean this type of stain off.

Do Lush bath bombs stain tubs?

Lush is a very popular brand of bath bombs and they have a wide range of colors and scents available.

Their bath bombs are highly colored which adds to the relaxing and soothing experience of getting a bath. Because their bath bombs are so highly colored and contain high amounts of oils there have been reports of bathtub staining.

This will occur just as they do with any other bath bomb and it will be totally dependent upon the coating on your tub. If the coating is fine then you should not notice any staining to your tub, however, if the coating on your tub is worn down there is a chance it could get stained.

Tips to stop a bath bomb staining your tub.

Here are some tips that should help to minimize any staining to your bathtub whilst using bath bombs.

  • If possible try to buy bath bombs that are not too brightly colored. The more color the bath bomb has the more likely it is to stain.
  • Always fill your tub up to your desired level and temperature before dropping your bath bomb into the water. The more water that is in the bathtub, the less concentrated the color and oils will be in the water.
  • As soon as you are finished in your bath make sure to shower down or wash out the bathtub. This will remove any leftover color before it gets a chance to stain.
  • When cleaning your bath make sure to use a cleaning spray that is not too harsh as this can cause the coating to break down which will leave your tub susceptible to staining.

Final thoughts.

To summarise, It is quite rare for bath bombs to stain your tub. There are ways that you can prevent staining from happening and if you do get a stain it is usually not very difficult to remove.

If you are worried about your bath bomb causing a stain then try to buy one that is not too brightly colored or one that does not have too many oils in it. Also, make sure to fill up your tub with water before adding the bath bomb and to shower down or wash out the tub as soon as you are finished.

If you follow these tips then you should not have any problems with bath bombs staining your tub. Thanks for reading! I hope this has helped.
