Painting a fiberglass bathtub is an excellent way to give your bathroom a fresh new look without the expense of a full replacement. Over time, bathtubs can become dull, scratched, or stained, detracting from the overall appearance of your space.
With the right tools, preparation, and a bit of patience, you can restore its original beauty or even change its color to better match your style. This guide on how to paint a fiberglass bathtub will walk you through the steps to achieve smooth, professional-looking results.
Why Paint a Fiberglass Bathtub?

10 Step-by-Step Guidelines on How to Paint a Fiberglass Bathtub
Step 1: Prepare the Bathtub
Begin by thoroughly cleaning the bathtub to remove any soap scum, dirt, or oils. Use a strong cleaner such as TSP (trisodium phosphate) or a vinegar solution to ensure the surface is free of residue. Rinse the tub thoroughly with water and allow it to dry completely. Once dry, sand the surface of the bathtub using sandpaper or a sanding block to create a rough texture, which will help the paint adhere properly.
Wipe down the tub with a clean, damp cloth to remove any dust or debris from sanding. Lastly, the surrounding areas should be protected by applying painter’s tape to the edges and covering nearby surfaces with drop cloths or plastic sheeting. This preparation step is essential for achieving a smooth, long-lasting finish.
Step 2: Protect Surrounding Areas
Before you begin painting, it’s crucial to protect the areas around the bathtub to prevent accidental spills or splatters. Use painter’s tape to cover the edges of the tub, fixtures, and any other surfaces that should not be painted.
Additionally, drop cloths or plastic sheeting should be laid down to safeguard the floor and surrounding walls. Paying attention to these details will ensure that your painting job remains clean and professional, saving you from unnecessary cleanup later.
Step 3: Tape Off Edges and Fixtures
Using painter’s tape, carefully tape off the edges of the tub, including where the tub meets the walls, floor, and any adjoining fixtures. Ensure the tape adheres firmly to prevent paint from seeping underneath.
Be precise when taping around faucets, showerheads, and any other hardware to maintain clean lines. This step is essential for achieving a neat and professional-looking finish without accidental splatters or uneven edges.
Step 4: Sand Down the Surface
Before applying paint, thoroughly sand the surface of the tub to ensure better adhesion. Use fine-grit sandpaper (about 220 grit) to gently scuff the entire surface. Focus on removing any glossy finish or imperfections, but be careful not to sand too aggressively, as this can damage the tub.
After sanding, wipe the surface clean with a damp cloth to remove dust and debris. This step is crucial for creating a smooth and even base for the paint to adhere properly.
Step 5: Clean and Degrease
Once the sanding is complete, the next step is to thoroughly clean and degrease the tub. Use a cleaner specifically designed to remove grease and grime, such as a trisodium phosphate (TSP) solution or other heavy-duty cleaners. Apply the cleaner with a sponge or cloth, ensuring you reach every corner and crevice of the tub.
Rinse thoroughly with water to remove any residual cleaning solution. After cleaning, allow the tub to dry completely before moving on to the next step. This ensures that the paint will adhere properly and without interference from oils or residues left on the surface.
Step 6: Apply Primer
Once the tub is completely clean and dry, it’s time to apply a primer. Choose a primer that is specifically formulated for the type of surface you are painting, such as epoxy or bonding primer for bathtubs. Using a paintbrush or a foam roller, evenly coat the entire surface of the tub with the primer, making sure to cover all areas, including edges and corners.
The primer creates a strong base for the paint, ensuring better adhesion and durability. Allow the primer to dry fully, following the manufacturer’s recommended drying time, before proceeding to the painting step.
Step 7: Paint
Once the primer is completely dry, it’s time to apply the paint. Select a high-quality paint that is specifically designed for surfaces like bathtubs, such as epoxy or enamel paint, to ensure durability and resistance to moisture. Using a clean paintbrush or foam roller, begin applying the paint in thin, even coats.
Start with the edges and corners, then work your way to the larger surface areas, making sure to apply the paint smoothly to avoid streaks or bubbles. Allow the first coat to dry according to the manufacturer’s instructions before applying a second coat for better coverage and a more polished finish. Repeat as necessary, ensuring even layers, but avoid applying overly thick coats as this can lead to drips or uneven texture.
Step 8: Allow to Dry
Once the final coat is applied, allow the paint to dry completely. This step is crucial to ensure a smooth and durable finish. Refer to the paint manufacturer’s recommended drying time, as it can vary depending on factors such as paint type, humidity, and temperature.
Avoid touching or placing objects on the painted surface during this time to prevent smudges or imperfections. Patience during the drying process will reward you with a professional-looking result.
Step 9: Apply Second Coat (Optional)
If desired, apply a second coat of paint for enhanced color depth and durability. Ensure the first coat is completely dry before proceeding. Use the same method as the first coat, working in even strokes to cover the surface uniformly.
A second coat is particularly recommended for lighter colors or high-traffic areas that may require added resilience. Allow the second coat to dry thoroughly, following the same drying guidelines as before, to achieve a polished and lasting finish.
Step 10: Maintain
To prolong the life of your newly painted bathtub, avoid using abrasive cleaners or scrubbing too hard. Instead, use gentle cleaning products and a soft cloth to clean the surface. Additionally, avoid using sharp objects that could scratch the paint.
Following these steps on how to paint a fiberglass bathtub will not only refresh the look of your bathroom, but also save you money compared to purchasing a new bathtub. With proper maintenance and care, your painted bathtub can last for years to come. So why wait? Give your old fiberglass bathtub a new lease of life with a fresh coat of paint!
