Can You Paint a Shower Floor? (How-To)

Painting a floor is a great way to beautify and protect the floor. But can you paint shower floor? Here is the answer to that.

You can paint your shower floor. Painting shower floor helps to protect the floor from bacteria and mold infestation. It also increases the strength and durability of the shower floor making the floor cope better with use over time.

But you should only use moisture-resistant paint on the shower floor since the floor will be affected by moisture. The best type of paint to use on a shower floor is oil-based paint. Oil-based paints are durable, hard, and water-resistant enough to thrive on shower floors.

But that’s not all. There is more to know about painting over shower floors. For instance, does paint stick to shower floors? Let’s find out.

Does Paint Stick To Shower Floor?

Generally, the paint will stick to a shower floor since shower floors are usually made from materials that accept paint like concrete. However, this is for fresh or newly-installed shower floors.

If the shower floor has already been subjected to daily use, the paint will not stick properly to the floor. This is because the shower floor will have been riddled with stains, soap, hair, body oils, water, and the likes. All of these will cause grime on the shower floor making it difficult for paint to stick.

If you put paint directly on such a shower floor, the paint will become loose and blister off. So before you put paint on the floor, you should scrub, clean, and dry the shower floor properly to allow the paint to stick.

You should also know that if the shower floor has been painted before, the paint will not stick to it. Since shower floors are usually painted with moisture-resistant and hard paints, the existing paint coating will prevent the new paint from sticking. So you have to remove or sand the existing paint before applying a new coat.

So what type of paint should you use on a shower floor? Let’s find out.

What Type Of Paint Can I Use On Shower Floor?

Generally, the best type of paint to use on a shower floor is oil-based paint. Professional painters advise using oil-based epoxy paint on the shower floor.

This is because the paint is hard, colorful, and moisture-resistant. This means that the paint will thrive on the shower floor. Satin and semi-gloss paints also work on shower floors.

Water-based paints will also work on the floor but the paint wouldn’t last long. This is because water-based paints aren’t as strong or durable as oil-based paints. Also, water-based paints don’t have good water resistance which means the paint will quickly peel off if used on a shower floor.

You should also know that the type of material used to make the shower floor determines the type of paint to use. For instance, if the shower floor was tiled, oil-based paints will not stick properly. This is because the oils in the paint will not stick to the tiles since tiles have a slick texture.

For tiles, water-based or acrylic paints are a better option. Also, the type of finish you are going for determines the type of paint you will use.

Now, let’s check out how to paint a concrete shower floor.

How To Paint A Concrete Shower Floor?

Painting a concrete shower floor can be time-consuming. This is due to the level of prep work required before you can put paint on the floor. To paint a concrete shower floor, you’ll need the following tools:

  • Epoxy Paint
  • A paintbrush
  • Wire brush
  • Fine-grit sandpaper
  • Concrete paste
  • Detergent and buckets of water
  • A scrubbing brush
  • Rags
  • Paint primer
  • A paint mixer
  • A paint scraper or paint stripper

Here is a guide on how to paint over a concrete shower floor:

1. Remove Existing Paint

The first step is to remove any existing paint or finish from the concrete floor. You can use a paint scraper or a paint stripping paste to remove the existing paint.

After removing the paint, use a wire sponge to pluck out debris stuck on the floor. If the floor is damaged or cracked, fill the cracks with concrete paste and leave the floor for a few hours to cure.

If it’s a freshly-installed concrete shower floor, you need to allow the concrete floor to cure before you can paint over it. This will take a few days. You can use a dehumidifier to make the floor dry faster.

2. Wash The Floor

The next step is to wash the concrete shower floor. As explained earlier, shower floors are usually riddled with moisture, oils, soap, and grime. All of these will not let the paint stick well to the floor so you have to remove them.

To do this, mix some detergent in clean water. Then use the soapy water and a scrubbing brush to wash the concrete shower floor. After getting rid of the grime on the floor, rinse with enough water and leave the floor for a few days to fully dry.

3. Prime The Concrete Shower Floor

When the concrete shower floor is dry, apply a few coats of paint primer on the floor. Ensure to use only a stain-blocking and moisture-resistant paint primer.

Concrete surfaces are usually uneven and this can affect the quality of the finish. But the primer coating will cover the concrete and provide a smooth undercoat for the paint to bite into.

4. Paint The Concrete Floor

When the primer is dry, you can paint the floor. Ensure to use paint designed for shower floors like epoxy paint. You should know that epoxy paints come in 2-parts so you’ll need to mix the paint before using it. You should leave the shower floor to dry for at least 3 days before taking your bath on it.

How To Paint Shower Floor Tiles?

Painting shower floor tiles is a bit different from painting a concrete shower floor. To paint shower floor tiles, you’ll need the following tools and supplies:

  • Sandpaper
  • Painter’s Tape
  • Paint
  • Paint primer
  • Detergent
  • Sponge
  • Buckets of water

Here is a guide on how to paint shower floor tiles:

1. Clean The Tiles

The first step is to clean the tiles. To do this, mix some detergent in water and use a sponge to wash the tiles. Ensure to pay attention to the lines between each tile.

These lines are usually packed with grime and dust. You can use a needle or razor blade to poke out the debris stuck in the lines. After cleaning the tiles, rinse and wipe them with a clean cloth or a mop. The tiles will get dry in less than an hour and you can continue with the task.

2. Cover The Edges With Painter’s Tape

The edges of the tiles should be covered with painter’s tape to prevent paint from getting underneath the tiles. You should also cover the corners and lines where the tiles meet the walls with painter’s tape.

This is to prevent brush strokes or paint splatters on the walls. If you’ll like to design the tiles to suit your taste, you can also use painter’s tape to demarcate different areas of the tiles.

3. Apply A Coat Of Primer

This step helps to improve paint adhesion. Oil-based paints especially don’t stick well to tiles since tiled floors are slick. You only need a coat of paint primer on the concrete floor.

4. Paint The Concrete Floor

When the primer coat is dry, you can paint the floor. It’s usually better to spray paint tiles. If you use a paintbrush, you might notice brush marks on the finish.

Also, spraying helps with better coverage. Allow the paint to dry for at least 3 days before bathing on the floor.

Will Paint Make My Shower Floor Waterproof?

Paint can make your shower floor waterproof but only if you use waterproof paint. Oil-based paints especially have water-resistant qualities. So, if you use water-resistant paint, the shower floor will be waterproof or at least, water-resistant.

You can also make the shower floor waterproof by sealing the paint with a waterproof sealant when the paint is fully dry. However, ensure the sealant you use can be used on floors.

Final Words

Overall, you can paint over your shower floor but you need to prep the floor first. Also, you’ll need to use paint that can be used on bathroom floors. The best types of paint for shower floors are water-resistant paints. Other types of paint will peel off.
