Refinishing a plastic shower pan is a great way to restore it to its original condition without the mess and expense of replacing it. The process involves cleaning the surface, patching any holes or cracks, applying a primer, and then using an epoxy paint designed for plastic or fiberglass surfaces. This can be done by spraying or pouring on the paint, and multiple coats may be needed for full coverage. After the final coat has dried, you can use an auto wax to achieve a higher-gloss finish, but this should be avoided on the bottom of the pan to prevent slipping. The entire process can be completed in a few hours, and your shower will be ready to use again within 24 to 36 hours.

What You'll Learn
Preparing the surface
Firstly, ensure the shower pan is clean and free of any dirt, soap scum, or residue. You can use a sharp razor or putty knife to carefully remove any caked-on soap scum or caulking, being mindful not to damage the shower pan itself. A thorough cleaning can reveal a cleaner shower pan underneath, and in some cases, this might be enough to improve the appearance without needing to resurface.
Next, you'll want to use a bleach-based cleaner or a mixture of trisodium phosphate (TSP) and warm water to deep clean the surface. This step ensures that any remaining contaminants are removed before applying the new coating.
Once the shower pan is clean, it's time to address any imperfections on the surface. Use a repair kit to patch up holes or cracks. These kits typically include epoxy filler and application tools, and for larger holes, you might also need fiberglass mesh cloth. Filling in these imperfections ensures a smooth and even surface for the new finish.
After the shower pan is clean and repaired, it's important to sand the surface. Use fine-grit sandpaper (around 220-grit) to scuff the shower pan lightly. Sanding creates a rough texture, which helps the paint adhere better and provides a raised surface for the new coating to grip onto. Be sure to wipe away the sanding dust with a damp cloth before proceeding to the next step.
Finally, apply a primer designed for use with plastic or fiberglass surfaces. The primer will bind with the sanded surface and provide a base for the paint to adhere to. Spray or apply the primer in light, regular coats, ensuring that you cover the entire shower pan. Allow the primer to dry completely before moving on to the resurfacing stage.

Choosing the right paint
When it comes to choosing the right paint to resurface a plastic shower pan, there are several factors to consider. Firstly, it's important to select a paint that is specifically designed for use on plastic or fibreglass surfaces. Epoxy-based paints are often recommended for this purpose, as they can provide a durable and long-lasting finish. Some popular options include the Rust-Oleum tub and tile refinishing kit and the Homax tub and tile refinishing kit, both of which are designed for use on acrylic or fibreglass surfaces. These kits typically include everything you need for the project, including the paint, hardener, application tools, and cleaning supplies.
Another important consideration is the colour of the paint. While some people may prefer to stick with a classic white or almond shade, others may opt for a more unique colour or finish. For example, terrazzo shower pans with a speckled or flecked look can help hide imperfections and give your shower a unique style. Additionally, some companies offer colour-matching services, allowing you to match the colour of your shower pan to an existing sink or toilet.
It's also essential to prepare the surface properly before painting. This includes thoroughly cleaning the shower pan to remove any dirt, soap scum, or residue. A sharp razor or putty knife can be used to remove caked-on soap scum and any leftover caulk. Once the surface is clean, it's important to sand it down to create a rough surface for the paint to adhere to. This can be done using sandpaper or a razor blade.
After the surface is prepared, a primer should be applied to create a base for the paint. This will help the paint adhere better and create a more even finish. Once the primer is dry, the paint can be applied using a spraying device or a paintbrush. It's important to follow the manufacturer's instructions for drying time between coats and to ensure proper ventilation during the painting process.
Finally, some additional tips to consider when choosing the right paint include the coverage of the paint and the drying time. Make sure to calculate the square footage of your shower pan to determine how much paint you will need. Most kits will specify the coverage area, so you can choose the one that best suits your needs. Additionally, consider the drying time of the paint, as some paints may take longer to cure, and plan your project accordingly.

Applying the primer
Before applying the primer, it is important to prepare the surface of your plastic shower pan. Start by cleaning the shower pan thoroughly, removing any dirt, soap scum, or soap residue. You can use a sharp razor blade or putty knife to remove any caulking on the curb, sides, or floor of the shower pan, being careful not to damage the pan itself. Then, mix 1/2 cup of trisodium phosphate (TSP) with a gallon of warm water and use it to wash the shower pan. Rinse well and ensure the pan is completely clean and dry before proceeding.
Once the surface is prepared, you can begin applying the primer. If you are using a refinishing kit, the primer may be included. If not, you will need to purchase a primer suitable for use on plastic shower pans. Follow the instructions on the primer product for the best results.
To apply the primer, use a light and regular spray from one side of the pan to the other. Ensure you are wearing protective gear, such as a respirator, to avoid inhaling any fumes. You may need to apply two coats of primer to ensure complete coverage. Allow the primer to dry thoroughly according to the manufacturer's instructions before moving on to the next step.
Some primers may require light sanding after they have dried to create a smooth surface for the paint to adhere to. If needed, use a fine-grit sandpaper (such as 220-grit) and lightly sand the primed surface. Wipe away the sanding dust with a damp cloth before proceeding.
After the primer is applied and dried, you can move on to the next step, which is typically applying the paint. By following these steps and allowing adequate drying time, you will ensure a smooth and durable finish for your resurfaced plastic shower pan.

Painting the shower pan
Painting a plastic shower pan requires a different type of paint than you would use for wood or metal. Many manufacturers supply relatively inexpensive two-part epoxy paint specially formulated for plastic shower pans and bathtubs. A typical kit contains epoxy and hardener, application tools, cleaning supplies, and sometimes a special primer to prepare the surface for the paint.
Before painting, it is important to clean the shower pan thoroughly. Remove any dirt, soap residue, or leftover caulk in the area. Use a sharp razor scraper to remove layers of caked-on soap scum and scrape it over all the smooth parts of the shower pan, including the curb. Use the razor blade to remove any caulking on the curb, sides, or floor of the shower base. Once you're done, mix 1/2 cup of trisodium phosphate (TSP) with a gallon of warm water. Wash the shower base thoroughly and rinse well.
After cleaning, the next step is to sand down the surface of the shower pan. Sanding will help the paint find raised surfaces on which it can stick. Once the surface is prepared, apply the primer in a light, regular spray from one side to the other. You may need to apply two coats of the primer to ensure that your shower pan is completely covered. Once the primer dries, use an epoxy paint designed for use with plastic shower pans. Place the paint in your spraying device and use a respirator to prevent inhalation of the fumes. Spray the paint from one side of the pan to the other and allow it to dry. Add a second coat and let it dry as well. Repeat this process 4-5 times, allowing each coat to dry before adding another.
Once the final coat of paint has dried, you can assess the coverage of the shower pan. If you see any areas that have not been covered by the paint, you can touch them up with a small paintbrush. If you want a higher-gloss finish than the paint provides, rub auto wax on the finished surface after the paint has fully cured. To avoid creating a slipping hazard, use the wax only on the sides of the pan and not on the bottom. Buff it to a high gloss with an electric buffer.
