What You'll Learn
Use a paint system made for adhering to plastic
If you're looking to paint a plastic shower, you'll need a paint system specifically designed for adhering to plastic. Paint systems like Rust-Oleum's are easy to find and use. These paints are formulated to bond well with plastic or acrylic surfaces and can be purchased as a tub or spray. It is important to note that regular paint will not adhere properly and can chip or peel off over time.
Before painting, it is crucial to prepare the surface properly. Start by giving the shower a deep clean using your usual bathroom cleaner and an abrasive sponge to remove any soap scum, dirt, or grease. Once the surface is thoroughly cleaned and dried, lightly sand it with fine-grit sandpaper to create a rough texture for the paint to adhere to. Be sure to clean off any dust after sanding and cover the edges of your shower with tape to protect the surrounding areas.
After preparing the surface, apply a primer suitable for plastic surfaces, such as a bonding agent, to help the paint bond better and create a smooth base for your paint. Allow adequate drying time before proceeding to the next step.
Now you're ready to apply your paint. Follow the manufacturer's instructions for mixing and applying the paint. You can use a small roller, brush, or spray method for application, depending on your preference and the paint system you've chosen. Ensure good ventilation during the painting process and allow enough drying time between coats.
Finally, finish with a layer of acrylic topcoat to seal in your paint and add extra shine. With these steps and the right paint system, you can successfully paint your plastic shower and give it a new lease of life.

Prepare the surface by cleaning and sanding
To prepare the surface of a plastic shower for painting, it is important to clean and sand it thoroughly. This will ensure that the paint adheres properly and that the final result is smooth and even.
Start by giving the shower a deep clean. Use a non-abrasive, all-purpose bathroom cleaner and an abrasive sponge to scrub away any soap scum, dirt, grease, or grime. Pay extra attention to areas with stubborn stains or discolouration. Rinse the surface thoroughly to remove any remaining cleaning product residue.
Once the shower is clean and dry, it's time to sand. Sanding the surface of the plastic will create a rough texture, providing a better grip for the paint to adhere to. Use fine-grit sandpaper, such as 220-grit or 400-grit wet/dry sandpaper, and lightly sand the entire surface. Be sure to sand in the direction of any grain or pattern on the plastic to ensure an even finish. After sanding, use a vacuum cleaner or clean cloth to wipe away any sanding residue, then remove the last traces of dust with a tack cloth.
It is crucial to ensure that the surface is completely dry before proceeding to the next step. Any moisture left on the surface can interfere with the paint's adhesion.

Apply a primer or bonding agent
After cleaning and sanding your plastic shower, the next step is to apply a primer or bonding agent. This is an essential step to ensure the paint adheres well to the surface and that your paint job is long-lasting. It will also help smooth out the surface of the plastic shower, allowing your paint to go on more smoothly and creating an attractive finish.
Before applying the primer or bonding agent, make sure you have the correct safety gear. Wear a face mask and gloves to protect your skin and respiratory system. You should also lay down something to cover your floor, such as newspaper, in case of any paint drips. It is also a good idea to cover your taps and plug holes with masking tape to keep them free of paint.
When choosing a primer, select one that is suitable for plastic surfaces. For example, if your shower is made of PVC, you can use a Xim vinyl primer. If you are using a brush-on paint, you may want to thin the primer with a small amount of water to help it flow more easily. Apply the primer in thin, even coats, and be sure to follow the manufacturer's instructions for mixing and application. Allow adequate drying time before moving on to the next step.
If you are using a bonding agent instead of a primer, follow the same safety precautions and surface preparation steps as you would with a primer. Bonding agents can be applied using a spray or brush method. Again, be sure to follow the manufacturer's instructions and allow adequate drying time before proceeding to the next step, which is painting.
By taking your time and following the proper procedures, you can achieve a smooth and durable finish on your plastic shower.

Apply paint with a brush, roller, or spray
Painting a plastic shower can be a great way to cover up old staining and give your bathroom a new look. It is important to use the right paint and tools for the job. For acrylic showers, it is essential to use paint specifically formulated for plastic or acrylic. Regular paint will not adhere properly and can chip or peel off over time.
Paintbrush
To paint with a brush, dip the brush into the paint to about one-third of the total length of the bristles. Dab the brush against the inside of the paint tray to remove excess paint. Do not wipe the brush against the rim of the can. Position the brush vertically against the surface, using the narrow edge as a guide. Gently smooth out, or "feather," the edges with the brush to avoid hard edges from paint lines.
Paint Roller
First, remove any lint from the roller by lightly pressing painter's tape on the roller cover. Lightly dampen the roller and remove any excess moisture with a paper towel. Roll the roller cover into the deep end of the paint tray several times to cover the entire surface with paint. The roller should not drip when moved. Fill a paint tray with about one inch of paint and roll the roller back and forth until it is fully saturated. Roll the paint onto the wall using a slightly angled, upward stroke. You can apply paint using a W or N shape to coat the wall evenly.
Paint Sprayer
Using a paint sprayer can be more expensive and messy, but it gives the most even finish. It can be tricky to get the right intensity and distance from the wall, so you may need to do a few practice passes. Paint sprayers also tend to use more paint than rollers or brushes, and switching colours can be complicated.

Finish with a layer of acrylic top coat
Once you have applied the paint of your choice, it is important to finish with a layer of acrylic top coat. This is a crucial step in the painting process as it seals in the paint and adds extra shine to the surface. It also provides a protective layer that will enhance the durability of your paint job.
When selecting an acrylic top coat, opt for a product that is specifically designed for use on plastic or acrylic surfaces. This is important because regular paint will not adhere properly to these surfaces and can chip or peel off over time. Look for products labelled as "acrylic enamel", as these are suitable for use on plastic and acrylic and will result in a durable, long-lasting finish.
Before applying the acrylic top coat, ensure that you have followed the necessary preparation steps. This includes cleaning the surface with a non-abrasive cleaner to remove any soap scum, dirt, or grease. Once the surface is clean and dry, lightly sand it with fine-grit sandpaper to create a rough texture. This step will help the top coat adhere better to the surface.
When you are ready to apply the top coat, follow the manufacturer's instructions for mixing and application. Ensure good ventilation in the room, and allow adequate drying time before using the shower.
By following these steps and finishing with an acrylic top coat, you will enhance the durability and shine of your painted plastic shower.
