Do Bath Bombs and Shower Bombs Stain Tubs?
Bath bombs and shower steamers are meant to turn everyday routines into something special - not leave behind a mess. The good news? Staining is very uncommon when products are used properly and on well-maintained surfaces (after 11 years in the business we've not actually had a complaint to date).
At Phoenix Bath and Body, our bath bombs and shower steamers are made with cosmetic-grade, skin-safe colorants designed to rinse cleanly. In most cases, a rinse down after use is all it takes. However, certain tub or shower conditions can make staining more likely.
Let’s break down why stains happen, how to prevent them, and what to do if you notice any color left behind.
Why Can Staining Happen?
If staining occurs, it’s usually due to the condition of the surface - not the bath bomb itself. Common causes include:
Soap scum or residue buildup
Pigments can cling to leftover soap residue/scum, oils, or grime already on the tub.
Hard water minerals
Minerals in hard water can react with dyes and oils, making color more likely to stick.
Porous or worn surfaces
Older tubs, chipped or scratched enamel, unsealed grout, textured finishes, or natural stone can absorb color more easily.
Not rinsing promptly
Allowing colorants or oils to sit for long periods increases the chance of residue.
How to Prevent Tub or Shower Stains
A few simple habits can go a long way in keeping your bathroom spotless:
Start with a Clean Tub
Before using a bath bomb, make sure your tub or shower is free of soap scum or buildup. A clean surface gives pigments nothing to cling to. Sometimes this scum is difficult to see so utilising a non-scratch cleaning device & detergent is essential.
Rinse Right After Use
Once your bath or shower is done, rinse the area with warm water to wash away any remaining color or oils.
Fill the Tub All the Way
More water means better dilution. A full tub helps keep colors and oils evenly dispersed instead of concentrated in one spot.
Be Mindful of Surface Type
Avoid placing bath bombs directly on unsealed grout, natural stone, or heavily worn areas. If needed, a bath liner can add extra protection.
Use Gentle Cleaning Products
Harsh chemicals can break down tub coatings over time, making surfaces more prone to staining. Stick with non-abrasive, tub-safe cleaners.
What If You Notice Color Left Behind?
Don’t panic - most residue comes off easily with gentle cleaning, if regular dish detergent doesn't work, you can try the below options:
Baking soda paste
Mix baking soda with a little water, apply to the area, and gently scrub with a soft cloth.
Hydrogen peroxide
For stubborn spots, apply a small amount (test first) and wipe clean after a few minutes.
Non-abrasive bathroom cleaners
Products work well when used according to directions and matched to your tub material.
Avoid rough scrubbers or harsh abrasives, especially on acrylic or fiberglass tubs.
Tub Material Matters
Different tub surfaces need different care:
Acrylic & fiberglass tubs
Non-porous but scratch easily. Always use soft cloths and gentle cleaners.
Porcelain tubs
More stain-resistant, but harsh or acidic cleaners can damage the finish over time.
Keeping your tub in good condition not only helps prevent stains - it also extends its lifespan.
Enjoy Your Bath, Worry-Free.
Bath bombs and shower steamers are meant to be enjoyed. With a clean surface, proper water levels, and a quick rinse afterward, staining is rare. And if you ever see a little color left behind, it’s usually an easy fix.
Please note: Our bath bombs and shower steamers are formulated to rinse cleanly, but staining can depend on individual tub or shower conditions, surface materials, and maintenance habits. While we do everything we can to ensure worry-free use, Phoenix Bath and Body cannot be responsible for any staining caused by worn, porous, or improperly maintained surfaces.
Now with that out of the way - go soak, steam, and relax. 🛁✨
