Painting an RV shower can be a great way to give it a new look without breaking the bank. The process is relatively simple and can be done using spray paint or epoxy paint. It is important to clean the surface thoroughly and sand it to ensure the paint adheres well, especially if the shower has accumulated years of grime. If you're painting over plastic, it's crucial to use a paint that adheres well to plastic, and you may need to prime the surface first. Once the paint job is complete, it's recommended to let it dry and ventilate for at least 24 hours before using the shower again.

Choosing the right paint
Painting your RV shower can be a great way to make it look new and modern without breaking the bank. When it comes to choosing the right paint, there are several factors to consider. Firstly, it is important to determine the material of your shower. RV showers can be made of different materials, such as plastic, fiberglass, or even tile. The type of material will influence the type of paint you should use.
If your RV shower is made of plastic, it is crucial to choose a paint that adheres well to plastic. Some paints may not bond properly with plastic surfaces, leading to chipping and peeling over time. Look for paints specifically designed for use on plastic or consider using a primer first to improve adhesion. Spray paint is a popular choice for painting plastic showers, as it can provide a smooth and even finish. However, be mindful of potential overspray, and always follow the manufacturer's instructions for best results.
For a more durable option, consider using an epoxy paint. Epoxy paint is known for its strong adhesion and longevity. It can be applied to a variety of surfaces, including plastic, fiberglass, and tile. Epoxy paint provides a porcelain-like finish and is highly resistant to chipping and peeling. However, it is important to note that epoxy paint may have limited colour options, and the application process can be more involved. Ensure the room is well-ventilated when working with epoxy paint due to its strong odour.
If you're looking for a quick and easy solution, traditional spray paint or regular wall paint can also be used. While they may not last as long as epoxy, they can still provide a fresh look to your shower. Just be sure to properly clean and prepare the surface before painting and consider using a primer for better adhesion. Traditional spray paint is readily available in various colours, allowing you to easily match your shower to your desired aesthetic.
Lastly, consider the finish you want for your shower. Do you prefer a satin, semi-gloss, or gloss finish? The desired aesthetic and ease of cleaning should influence your decision. A gloss finish, for example, can make your shower shine but may require more frequent cleaning to maintain its appearance. Weigh the benefits of each finish and choose the one that aligns with your preferences and maintenance expectations.

Preparing the surface
Clean the Surface: Start by thoroughly cleaning the shower surface to remove any dirt, grime, or soap scum that has built up over time. Use a mild detergent or a vinegar-water solution to cut through the grease and grime. Make sure to pay extra attention to areas with stubborn stains or discolouration. It is important to ensure that the surface is completely clean before moving on to the next step.
Sand the Surface: Once the shower surface is clean and dry, it's time to lightly sand it. Sanding will create a rough texture, which will help the paint adhere better to the plastic surface. Use fine-grit sandpaper or a sanding block to gently scuff the surface, being careful not to apply too much pressure, which could damage the plastic. A light sanding is usually sufficient to create the desired texture for paint adhesion.
Remove any Impediments: If there are any metal panels or fixtures attached to the shower, such as old shower doors or handles, it is recommended to remove them if possible. This will ensure that you have a smooth and unobstructed surface to work on and will also prevent any paint from getting on these fixtures.
Apply a Primer: Before painting, it is essential to apply a suitable primer, especially if you are painting over a plastic surface. A primer will help the paint adhere better and create a more durable finish. Look for a primer that is specifically designed for use on plastic surfaces, such as a 2-in-1 spray paint and primer. You may also need to consider using a stain-blocking primer if you are covering up water or smoke stains.
Protect the Surrounding Area: Painting can be a messy process, so it is important to take the necessary steps to protect the surrounding area. If possible, remove any items or fixtures that could be affected by the paint. Use drop cloths or plastic sheeting to cover the floor and any nearby surfaces. Additionally, open all windows and set up a fan to ensure proper ventilation during the painting process.
By following these steps, you will effectively prepare the surface of your RV shower for painting, ensuring a smooth and professional-looking finish.

Painting technique
Painting an RV shower is a simple task that can make a big difference in the overall appearance of your RV bathroom. Here is a step-by-step guide on how to paint your plastic RV shower:
- Clean the Surface: Start by thoroughly cleaning the shower surface to remove any dirt, grime, or soap scum. This step is crucial as it ensures that you are painting on a clean surface, allowing for better paint adhesion.
- Prepare the Area: Open all windows and set up a fan to ensure adequate ventilation. Epoxy paint, in particular, has a strong odour, so it is important to ventilate the area well before you start painting.
- Sand the Surface: Lightly sand the entire tub to create a rough surface for the paint to adhere to. This step is especially important if you are using epoxy paint or a primer. Use a fine-grit sandpaper or a sanding block to smooth out any imperfections and create a uniform surface.
- Apply a Primer: If your shower walls have stains or if you want the paint to adhere better, consider using a primer. Look for a stain-blocking primer like a shellac-based or oil-enriched primer. Allow the primer to dry completely before proceeding to the next step.
- Choose the Right Paint: Select a paint that is specifically designed to adhere to plastic surfaces. Regular spray paint can be used, but it is recommended to get the 2-in-1 variety that includes a primer. You can also opt for epoxy paint, which is known for its durability and ability to provide a porcelain-like finish.
- Paint Application: When painting, use smooth and even strokes, being careful not to overspray. Apply the paint generously and evenly across the surface of the shower. Allow the paint to dry for at least 2 hours between coats. Depending on the coverage and your preference, you may need to apply a second or third coat.
- Drying and Curing: Once you have finished painting, allow the shower ample time to dry and cure. This process can take at least 24 hours or even longer, depending on the type of paint used. Ensure that the area remains well-ventilated during this period.
- Clean Up and Touch-Ups: After the paint has dried, inspect the shower for any areas that may need touch-ups. Lightly sand any uneven areas and apply additional coats of paint as needed. You can also use a sanding block to smooth out any rough edges or imperfections.
- Re-caulk the Seams: Finally, use a caulk gun to fill in the seams and create a seamless finish. Choose a coloured caulk that matches your new shower colour, ensuring that it is waterproof and paintable.
By following these steps and techniques, you can transform the look of your plastic RV shower, making it look new and modern.

Drying time
Before starting the painting process, it is essential to prepare the surface properly. This includes cleaning and sanding the shower surface to remove any dirt, grime, or gloss finish. It is also recommended to use a vinegar-water solution to rub down the entire tub/shower to ensure the surface is ready for painting. This preparation process can take some time, depending on the condition of your shower and how much cleaning and sanding is required.
Once the surface is prepared, you can start applying the paint. If you are using a spray paint, it is important to spray with smooth and even strokes to ensure a consistent coat. Allow the paint to dry for at least 2 hours between coats. The number of coats required may vary, but generally, two coats of paint should be sufficient. However, if you feel your tub needs more coverage, you can apply a third coat.
After you have finished painting, you will need to let the paint dry completely. This process can take at least 24 hours, and it is important to ensure that the vapors have cleared before using the shower again. During this drying time, you can use a fan to improve ventilation and speed up the drying process. It is crucial to follow the manufacturer's instructions for the specific paint you are using, as drying times may vary depending on the type of paint and the number of coats applied.
Some paint options, such as epoxy, may have a strong smell, even with proper ventilation. In such cases, it is recommended to wear a face mask and take breaks to get some fresh air. The drying time between coats of epoxy can be around 3 hours, according to the instructions for certain paint-on epoxies.
Additionally, it is worth noting that some paints, like oil-based paints, may take a long time to completely cure and stop smelling like paint. For example, one user reported that their paint job took a year to lose its paint smell.

Finishing touches
Once you have painted your RV shower, there are a few finishing touches you can add to ensure a long-lasting and attractive finish. Here are some detailed tips to complete your project:
Clean and Sand the Surface
Before applying any paint or topcoat, ensure the surface is clean and sanded. Use a vinegar-water solution or a mild detergent to remove any dirt, grime, or residue. Then, lightly sand the entire tub with fine sandpaper to create a slightly rough texture. This process will help the paint adhere better and create a smoother finish.
Apply a Bonding Agent or Primer
To ensure the paint adheres well and the finish is long-lasting, apply a bonding agent or a primer. This step is crucial, especially if you are using spray paint. Choose a 2-in-1 spray paint that includes a primer, or apply a separate primer before spraying. Allow adequate drying time for the primer or bonding agent according to the manufacturer's instructions.
Re-caulk the Seams
After painting, use a caulk gun to fill in the seams and create a seamless look. Select a coloured caulk that matches your new shower colour. Ensure the caulk is waterproof and paintable. Smooth out the caulk with your finger or a damp cloth for a neat finish.
Apply an Acrylic Top Coat (Optional)
Consider finishing your painted shower with an acrylic top coat. This extra layer will seal in the paint, add extra shine, and enhance the overall durability of your work. Allow each layer to dry completely before applying the next, and follow the manufacturer's instructions for drying times.
Ventilation and Protection
Throughout the painting process, ensure proper ventilation by opening windows and setting up a fan. The paint fumes can be overwhelming, so wear a face mask and gloves to protect yourself from inhaling the vapours and accidental contact with the chemicals.
