How to Fix a Peeling Bathtub: A Comprehensive Guide

A peeling bathtub can be a frustrating and unsightly problem. Whether your tub is made of fiberglass, acrylic, or enamel, peeling can occur due to various reasons such as age, poor refinishing, or exposure to harsh chemicals. Fortunately, fixing a peeling bathtub is a manageable DIY project with the right tools and techniques. This guide will walk you through the steps to restore your bathtub’s appearance and functionality.

Understanding the Causes of Bathtub Peeling

Before diving into the repair process, it’s essential to understand why your bathtub is peeling. Common causes include:

Age and Wear: Over time, the surface of the bathtub can wear down, leading to peeling.
Improper Refinishing: If the bathtub was previously refinished and not properly prepared or coated, it can start to peel.
Harsh Cleaners: Using abrasive or harsh chemical cleaners can damage the surface of the bathtub, causing it to peel.
Moisture: Continuous exposure to water can cause the finish to break down, especially if the tub wasn’t properly sealed.

Tools and Materials You Will Need

To fix a peeling bathtub, you will need the following tools and materials:

  • Safety goggles and gloves
  • Sandpaper (220-grit and 400-grit)
  • Utility knife or razor scraper
  • Painter’s tape
  • Drop cloth or plastic sheeting
  • Epoxy or bonding agent
  • Bathtub refinishing kit (includes primer, paint, and topcoat)
  • Paintbrush or roller
  • Ventilation mask

Step-by-Step Guide to Fixing a Peeling Bathtub

Step 1: Prepare the Area

Ventilation: Ensure the bathroom is well-ventilated. Open windows and use a fan to circulate air. Wearing a ventilation mask is also recommended to avoid inhaling fumes.
Protect Surroundings: Use a drop cloth or plastic sheeting to protect the bathroom floor and nearby fixtures. Apply painter’s tape around the edges of the bathtub to protect walls and trim.

Step 2: Remove Peeling Coating

Scrape Off Loose Coating: Using a utility knife or razor scraper, gently remove any loose or peeling coating. Be careful not to damage the underlying surface of the tub.
Sand the Surface: After removing the loose coating, use 220-grit sandpaper to smooth out the edges of the peeled areas. Follow up with 400-grit sandpaper to ensure a smooth surface. This helps the new coating adhere better.

Step 3: Clean the Bathtub

Clean Thoroughly: Clean the bathtub with a non-abrasive cleaner to remove any dust, debris, or soap scum. Rinse thoroughly and let it dry completely. Any remaining residue can prevent the new coating from adhering properly.

Step 4: Apply Epoxy or Bonding Agent

Apply Epoxy: Use an epoxy or bonding agent to prepare the surface for refinishing. Follow the manufacturer’s instructions for mixing and applying the epoxy. This step is crucial for ensuring that the new finish adheres properly and lasts longer.

Step 5: Prime the Bathtub

Apply Primer: Once the epoxy has dried, apply a primer from your bathtub refinishing kit. The primer helps the paint adhere better and provides a smooth base for the topcoat. Use a paintbrush or roller to apply an even coat, and let it dry according to the manufacturer’s instructions.

Step 6: Paint the Bathtub

Apply the Paint: After the primer has dried, apply the bathtub paint. Use a paintbrush or roller to apply an even coat. It’s usually best to apply multiple thin coats rather than one thick coat to avoid drips and ensure a smooth finish.
Let it Dry: Allow each coat to dry thoroughly before applying the next. This may take several hours to overnight, depending on the product.

Step 7: Apply the Topcoat

Apply Topcoat: Once the paint coats have dried, apply the topcoat included in the refinishing kit. The topcoat provides a protective layer that helps prevent future peeling and adds a glossy finish to the bathtub.
Final Drying: Allow the topcoat to dry completely. This might take 24-48 hours. Avoid using the bathtub during this period to ensure the coating sets properly.

Tips for Maintaining Your Bathtub

Use Gentle Cleaners: Avoid using abrasive or harsh chemical cleaners. Instead, use gentle, non-abrasive cleaners specifically designed for bathtubs.
Regular Cleaning: Regularly clean your bathtub to prevent soap scum and mildew buildup. This will help maintain the finish and prolong the life of the coating.
Avoid Heavy Impact: Be cautious not to drop heavy objects into the bathtub, as this can chip the surface and lead to peeling.
Ventilation: Ensure proper bathroom ventilation to reduce moisture buildup, which can deteriorate the bathtub’s finish over time.


Fixing a peeling bathtub requires some effort, but it’s a rewarding DIY project that can save you the cost of a full replacement. By following the steps outlined in this guide, you can restore your bathtub’s appearance and functionality, giving it a fresh, new look. Regular maintenance and proper cleaning techniques will help preserve the finish and keep your bathtub looking pristine for years to come.
