Are Bath Bombs Safe For My Tub?

There’s nothing quite as nice as slipping into a hot, frothy bath at the end of a long day to soothe your muscles and calm your spirit. But if you’re partial to using a fizzy bath bomb to get that moment of peace, you might be wondering, “Is using a bath bomb going to hurt my tub or my drains?”

Luckily, bath bombs are generally pretty safe for most tubs as long as you maintain them! Here’s what you should know about using bath bombs safely. 

What are bath bombs? 

Bath bombs are solid bath products that can be placed into your tub during bathtime. When the bombs come into contact with hot water, the moisture causes them to fizz and then dissolve. Many bath bombs also contain nourishing skincare ingredients and/or oils and plant extracts for promoting relaxation and mood. 

Are bath bombs safe for my tub?

In general, bath bombs are safe for your tub since they don’t inherently contain ingredients that are harmful to your tub or the drains. However, depending on the brand and the recipes that they follow, some bath bombs may also include certain ingredients that lead to clogging or staining. 

Common bath bomb ingredients 

Most bath bombs are made with three key ingredients: 

  • Baking soda 
  • Citric acid 
  • Cornstarch 

Baking soda and citric acid are the signature ingredients that differentiate bath bombs from other bath products. When exposed to hot water, these two ingredients dissolve and start a reaction with each other that results in that signature fizzing that you think of when you think of bath bombs. Many bath bombs also contain cornstarch, which is added to the formula to slow down the fizzing reaction and make the bomb last longer for a more prolonged bath experience. 

In addition to these three ingredients that are responsible for the reaction unique to bath bombs, you can also find a variety of therapeutic ingredients that address mind and body needs. For example, some common ingredients that you may find in Pacha’s Froth Bombs include:

  • Epsom salts for muscle relaxation 
  • Essential oils for scent, relaxation, and/or invigoration 
  • Moisturizing ingredients like cocoa butter, honey, or shea butter to promote hydration 

Finally, some bath bombs may also contain other additive ingredients like dried flower petals that add to the bath experience and may also carry therapeutic benefits of their own (like lavender and chamomile for relaxation, for example). 

Bath bombs and plumbing

The main ingredients found in bath bombs (baking soda, citric acid, and cornstarch) are not bad for your bathtub or your drains. However, other ingredients can clog your tub over time and with regular use if you aren’t regularly maintaining your drains. Some bath bombs might also run the risk of not fully dissolving, which can lead to buildup and clogs over time. Finally, certain dyes may stick around to your bathtub finish if they are not rinsed away properly. 

How to make sure your bath bombs don’t ruin your tub 

But just because some ingredients aren’t the best for your bathtub, it doesn’t mean that you can’t enjoy your bathtime to the fullest! Here’s what to do to ensure that your bath products are safe.

Clear out your drain frequently, especially if you use bath bombs and other bath products frequently. 

Pour boiling water down the tub to help dissolve any remaining materials that might be in the drain like salt. Then, pour in a mixture of baking soda and vinegar and close the tub stopper. The fizzing reaction between the baking soda and the vinegar can help clear out any clogs. If your tub is especially clogged, you may need to “snake” your drain using a long, thin wire. 

Avoid using bath bombs with plastic glitter. 

Glitter is often made out of tiny pieces of plastic, which means that those microplastics can end up clogging your tub over time (or worse: making their way into the water supply system). So the best route is to avoid using bath bombs with glitter altogether. If you do want some glitter fun out of your bath bombs, make sure they are derived from biodegradable ingredients to avoid harming your tub and the environment. 

If your bath bomb has larger ingredients like flower petals, wrap them in a cloth or sock before using. 

This can help catch those sediments and materials before they get into your drain and contribute to a blockage. 

Rinse your bathtub well after a bath. 

This will prevent dyes from sticking around and potentially staining your tub.
