Painting your fiberglass shower is a very smart move to upgrade your bathroom's interior. Why? First of all, it can save you a lot of money from hiring a contractor to install a new one and can save you a lot of time, since painting it yourself can be done in a few hours. Here is how:

Materials You Need

First thing's first: gather all of the materials you will need before you proceed. Here's what you'll need:

  • Sandpaper (300 or 320-grit)
  • Acetone cleaner
  • Masking tape
  • Plastic
  • Primer paint
  • Fiberglass paint
  • Brush
  • Breathing mask
  • Caulk

What Kind Of Paint Should You Use?

You should use waterproof enamel paint and primer. These will create a hard and durable finish. Enamel paint is also the easiest paint to apply since it is thick enough to flow throughout the surface using a brush.

What Kind Of Brush Should You Use?

When it comes to enamel paints, it is better to use natural-bristle brushes with chisel shape tips. These kinds of tips leave a smooth finish and do not leave harsh brush strokes on the surface. Flagged tips also hold a large amount of paint due to their wide tip and minimize brush stroke marks so they're good to use in painting broad areas.

Painting A Fiberglass Shower Procedure

Here are the steps you should follow to paint your fiberglass shower.If the shower has a door, it will be better to remove it since you might need extra space or ventilation during the process. 

  1. Clean the shower area thoroughly. Using a cleaning brush or a towel and warm water, scrub off any grime or soap residue on the surface. If silicon caulk is present on the edges, remove it with a scraper. Silicone caulk is not paintable.
  2. Wear a mask so you won't inhale the particles and chemicals from the next steps. Make sure that your mouth and nose are covered securely.
  3. Using the 300 or 320-grit sandpaper, begin sanding the wall where you will paint. This process will rough up the surface so that the primer can cling firmly. Also, sanding will smooth any bumps that are present so you can have a bump-free surface. 
  4. Wash off the debris on the wall and the floor with clean water. 
  5. While waiting for the fiberglass shower area to dry, wrap the faucets, knobs, or other fixtures with masking tape to prevent the paint from getting on them. 
  6. Once the area is completely dry, cover the floor with plastic or cloth. This way, the floor will be protected from any paint drips or smudge. To keep it in place, you can use the tape so it won't shift around as you move. 
  7. Open the windows and doors for ventilation during the painting process. You can also put a fan inside the bathroom so that the air can circulate or escape through the vents.
  8. Using your paintbrush, apply the primer to the surface. Wait for it to dry completely.
  9. Once you are sure that the primer is dry, start painting with the enamel paint. To get the desired color finish, apply 2 to 3 coats of it. Be sure to check out the manufacturer's instructions on this. Some of them suggest sanding in between coats for the best results.
  10. Once the paint is dry, you can remove the tape from the faucets and other fixtures, as well as the cover you put on the floor. 
  11. Reapply caulk on the edges where you removed it. 
  12. Do not use the shower area until everything is completely dry. To make sure it is dry, leave it for a good 24 hours.

Is Painting Your Fiberglass Shower Worth It?

Painting your fiberglass shower is worth it since it will save you time and money and allow you to preserve an old design and even choose a preferred color that will suit the rest of your bathroom's interior.

However, you should make sure that the shower is still in a good condition and does not need a major repair which could cost you more than buying a new one. 

Signs That You Need To Replace Your Fiberglass Shower

Here are some conditions that you should check to determine if you'd be better off replacing your shower than painting it. These are signs that the lifespan of your shower is coming to an end.

  • There are leaks on the shower head or faucet. This may be due to aged bolts or fittings that are beginning to loosen. Not only can this increase your water bill, but this can also lead to more problems such as the formation of mildew, mold, or watermarks on the wall. 
  • Your water sources such as showers or faucets have poor water pressure. Since the water that flows in American pipes is usually treated with chemicals such as chlorine and chloramine, it is safe for consumption. But it can lead to buildup and clog your shower heads over time. 
  • An excessive amount of holes, cracking, chipping, and peeling. 
  • Stubborn stains.

When scrubbing, do not use hard-bristle brushes and bleaches on the fiberglass because they will damage the surface. Instead, use a microfiber towel or a sponge and gently rub the mild cleaner across the surface to eliminate the stains. Once you are satisfied, rinse off the lather with clean water.

Additionally, here are some solutions you can use for cleaning. 

  • A mixture of vinegar (1 part) and water (3 parts)
  • A mixture of baking soda (1 cup) and water (1 tablespoon)
  • Sprinkling baking soda on the face of a halved citrus fruit like lemon 
  • Hydrogen peroxide

How Often Should You Clean Your Fiberglass Shower?

Cleaning your shower once a week is recommended to prevent the buildup of dirt, mildew, molds, soap scum, and more. Add this chore to your weekly cleaning schedule to keep your shower area clean and odor-free. 

Wrapping Up

Painting your fiberglass shower is possible to do—even by yourself. Also, enamel paint and a natural bristle paint brush are the best options to make a smooth and stroke-free finish on your fiberglass. Pair that with regular weekly cleaning using mild solutions and a non-abrasive scrubber, and you can will have like-new shower every time. 

Keep in mind that not every fiberglass shower should be painted, especially if the shower is starting to leak or clog and already has a lot of holes, cracks, peeling, or other type of damage. It is best to replace the shower if it is already in a damaged condition.
