What Causes Stains in Acrylic and Fiberglass Tubs?
Acrylic and fiberglass tubs are highly durable and long-lasting, but they are still prone to staining over time with regular use. Here are some of the most common culprits of bathtub stains:
- Soap scum – Residue from soap, shampoo, and body wash builds up on the tub’s surface.
- Hard water – Mineral deposits from hard water can leave limescale stains.
- Mold and mildew – Moisture that doesn’t dry fully allows mold and mildew to grow.
- Rust – Iron or other metal-based contaminants in the water supply can cause orange/brown rust stains.
- Hair products – Shampoos, conditioners, hair dyes can stain the tub.
- Bodily fluids – Things like blood or urine can stain if not cleaned up quickly.
- Cleaning products – Some harsh cleaners like bleach can discolor acrylic.
Over time, these staining agents build up and become more difficult to remove. That’s why it’s important to clean your tub regularly to prevent permanent staining.

When to Call for Professional Bathtub Refinishing
For extremely stubborn, set-in stains or damage that won’t scrub out, you may need to call in a professional bathtub refinishing service. Here are some signs it’s time to let the experts tackle your stained or damaged tub:
- The tub has permanent dull spots or etched areas that won’t buff out.

- You notice signs of damage around the drain or fittings.
- DIY efforts have failed to fully remove stains after multiple attempts.
- The tub surface feels rough or porous.
- You want to change the tub color entirely.
Professional reglazing can give your worn-out acrylic or fiberglass bathtub a brand new, factory-fresh finish. The process involves lightly sanding down the tub surface, applying new acrylic enamel coating, and curing it to harden. This resurfaces the tub to restore its glossy, smooth look and prevent further staining. Most bathtub refinishing jobs cost $400-$1000 depending on the tub size, location, and the amount of damage that needs repairing.
DIY Bathtub Refinishing Kits
If you don’t want to hire a professional, another option is to use a do-it-yourself refinishing kit. These kits come with acrylic enamel resurfacing liquid along with all the tools and supplies needed to recoat your tub at home. Here are the steps for using a DIY bathtub refinishing kit:
- Fully clean and dry the tub then roughen surface with included sandpaper.
- Wipe tub with denatured alcohol to remove residue.
- Apply acrylic bonding agent and let dry fully.
- Pour acrylic enamel into tray and use included roller to apply 2-3 even coats.
- Wait 6 hours between coats for proper drying and curing.
- Let cure for 24 hours before use. Avoid abrasive cleaners on resurfaced tub.
DIY kits can save you money compared to hiring out, but the process is labor intensive. You also need to be comfortable using chemical bonding agents. Follow all safety precautions when attempting to refinish a bathtub yourself. But if done properly, a refinishing kit can give you professional quality results.
The Cost of Bathtub Resurfacing
Here is a comparison of estimated costs for professional vs. DIY bathtub refinishing:
Method | Cost |
---|---|
Professional refinishing service | $400 – $1000+ depending on tub size and damage |

As shown, DIY bathtub refinishing can provide huge cost savings compared to hiring out. But professional reglazing services do all the challenging work for you and have specialized equipment that allows them to refinish tubs quicker than a first-timer could.
How Long Does Bathtub Refinishing Last?
On average, a professional bathtub reglazing or DIY refinishing job can last 5-10 years with proper care and maintenance. Here are some factors that influence longevity:
- Surface prep – Sanding provides better adhesion.
- Coats applied – More coats add durability.
- Curing time – Proper drying prevents chipping.
- Usage frequency – Heavy use wears down finish faster.
- Cleaning habits – Harsh cleaners shorten life.
- DIY vs. professional – Pros have more experience.
Refraining from using abrasive scrubbers or chemicals helps preserve the glossy acrylic finish. With gentle cleaning, you can enjoy a freshly resurfaced bathtub free of stains for years before needing to reapply a new coat.
Signs It’s Time to Redo Bathtub Refinishing
Even with proper prep and application, an acrylic tub refinishing job will eventually show signs of wear. Watch for these clues that it’s time to have your tub reglazed:
- Visible scratches, chips, or cracks in finish
- Areas feeling rough to the touch
- Noticeable loss of glossy sheen
- New stains/discoloration appearing
- Worn out caulking around edges
Tub refinishing can be redone multiple times if needed. Simply scrub away any old flaking finish, lightly sand and wipe clean, then reapply new acrylic enamel coats. This provides a fresh start without the cost of full tub replacement.
