A Step-by-Step Guide to Painting a Plastic Bathtub


Are you looking to revamp your bathroom on a budget? Painting a plastic bathtub is a cost-effective and transformative solution. In this comprehensive guide, we’ll walk you through the step-by-step process to give your plastic bathtub a fresh, new look. Follow these instructions diligently to achieve professional-looking results without breaking the bank.

Materials You’ll Need

To get started, gather the following materials:

  • Sandpaper (120-grit and 220-grit)
  • Plastic primer
  • Acrylic or epoxy paint
  • Painter’s tape
  • Drop cloths
  • Sponge
  • Rubbing alcohol
  • Tack cloth
  • Fine-grit steel wool
  • High-quality paintbrush or spray gun

Surface Preparation

Clean the Bathtub

Begin by thoroughly cleaning the plastic bathtub with a mixture of warm water and a mild detergent. This will remove any soap scum, grease, or other residues that might interfere with the painting process. Rinse the bathtub well and allow it to dry completely.

Sand the Surface

Use 120-grit sandpaper to lightly sand the entire surface of the bathtub. This helps the primer adhere better. Follow up with 220-grit sandpaper for a smoother finish. Wipe away the dust with a tack cloth.


Apply Plastic Primer

Choose a high-quality plastic primer suitable for your bathtub material. Apply a thin, even coat of primer using a paintbrush or spray gun. Allow the primer to dry completely according to the manufacturer’s instructions. This step is crucial for ensuring the paint adheres properly.


Choose the Right Paint

Opt for acrylic or epoxy paint specifically designed for plastic surfaces. These paints offer durability and resistance to moisture, ensuring your newly painted bathtub maintains its finish over time.

Apply the Paint

Using a high-quality paintbrush or a spray gun, apply the paint in smooth, even strokes. Be patient and allow each coat to dry thoroughly before applying the next. Multiple thin coats are preferable to a single thick coat for a professional finish.

Finishing Touches

Remove Painter’s Tape

Once the paint is completely dry, carefully remove the painter’s tape. This will reveal clean, crisp lines, giving your bathtub a polished appearance.

Clean Up

Clean your painting tools promptly with soap and water. Dispose of any drop cloths or masking materials responsibly.

Maintenance Tips

Congratulations, your plastic bathtub now boasts a fresh, vibrant color. To ensure the longevity of your work, follow these maintenance tips:

  • Avoid using abrasive cleaners, as they can damage the painted surface.
  • Clean the bathtub regularly with a gentle, non-abrasive cleaner.
  • Be cautious with sharp objects, as they may scratch the painted surface.

By following these steps and tips, you’ve successfully transformed your plastic bathtub into a stylish focal point of your bathroom.
