How to Paint Bathroom Countertops to Look Like Granite?

It is challenging to make bathroom countertops appear like granite if you do not have proper knowledge about color mixing and the type of material on countertops, like quartz or laminate.

How to Paint Bathroom Countertops to Look Like Granite? You can paint bathroom countertops to look like granite by preparing the surface, applying the primer, mixing and applying the paint, and topcoat the finisher. It is better to use waterproof paint and add a good quality sealant.

You can color the wood, laminate, and ceramic countertops to make them like granite because they are good candidates for applying paints and renovating the entire look.

Why would you paint the bathroom countertops?

Rock and stone slabs are always an attractive choice for any home decorator who loves to add a texture of natural elements to bathrooms.

Since the original granite countertops are a little expensive. Painting them like granite is much more affordable and will enhance the appearance of your place.

In addition, it looks like a packed grain-like surface of mica, silica, quartz, and feldspar that looks like an original stone if done nicely.

You can easily clean the surface because a fine finish will make the surface smooth and even.

In addition, it can cover the seams and pores if you have wooden counters, and the risk of moisture absorption decreases.

You can use a good sealant to make the surface water-resistant because water splashes from your vanity and sinks can make the counter wet. You can color it in any shade or color, depending on the color of the walls and vanity.

How do you paint the bathroom countertop to look like granite?

Painting the countertops like granite is not a difficult process if you have the skills to do it properly.

It is better to practice once on any rough board or laminate to ensure the desired design and color you want.

You will need some tools to start the process, such as desired colors, brushes, sponges, roller, tray, and tape.

Prepare the surface

You can start the process by preparing the surface of the countertops. You can take good dishwashing soap, vinegar, warm water, and a cloth to clean the surface.

Mix them in a bowl, dip the full cloth in the bowl, and wring it softly so that the diluted solution remains in the fabric.

Remove all the products and stuff from the counter and put painter’s tape around the walls and vanity. Then, wipe the cloth all over the surface, the walls, and the vanity to clean the dust, mold, and mildew.

You can take another bowl with warm water and a dry cloth to wipe it again on the surface. Rinse the cloth in the water bowl, wipe it over again to clean the soap and dirt properly, and let it dry for some time.

You can use sandpaper with 155 grit and rub the surface to remove any other dust or rust particles to make it smoother before applying paint.

Apply the primer

Applying primer before painting is an essential step as it can cover the surface to make it even and fill the pores if any. Primers come in different colors and textures depending on the type of counter you are going to paint.

It is recommended to use a light color primer to give the base a bright and prominent appearance.

Take a roller, dip it in the primer, and start moving it to and fro in a straight row to avoid air bubbles. Use small brushes to apply the primer to the areas which are difficult to cover with the roller.

Make sure to cover the full surface, including the edges and corners of your bathroom vanity, and let it dry for 5-7 hours.

Thoroughly wash the roller and brushes with warm water because you can use them again while applying topcoats. 

Apply the paint

Choose any color you want for your bathroom countertops, such as you can mix two color shades or three depending on the granite style you desire in your place.

Take out the paint in a tray and cut the sponge into two or three pieces if it is pretty large; otherwise, take three small sponges.

You can dip the sponge in water and wring it out before dipping the sponge into the paint. The moisture in the sponge will stop it from soaking too much color.

You can dip the sponge in the paint and dab it over the surface. Repeat the process for every color you have to give the desired granite look and adjust the pattern.

I took dark brown, black, and golden yellow colors to the countertop with a granite impression. First, dab the black color all over the surface in an up-down motion; then, the dark brown color overlapped with a golden yellow texture.

Use small brushes to draw random short lines and dab them lightly to add a natural granite look.

Do not completely cover the white primer coat on the base to show some white spots through the paint. Instead, let it dry for 2-3 hours and sand the surface with 320 grit to remove the high spots.


Pour some amount of finisher into the tray and apply the topcoat of it with a roller over the entire length and width of the surface.

Make sure to cover the full area and use brushes to apply them in the corners and edges of the vanity.

Let the first coat of finisher dry for approximately 7-9 hours and sand the high spots using light abrasive paper. You can apply the second coat of the finisher by repeating the same procedure. 

It is better to apply only two coats of finisher because more than two coats can make the glossy look of surface to look fade and dull.

In addition, you can remove the tape from the edges of the vanity and around the walls when the topcoat is completely dry.

Things to consider while painting your bathroom countertops

Painting the countertops of your bathroom to give a granite look can create issues if you do not have any skill or experience in it.

It is better to use waterproof or moisture-resistant paints on countertops because of the damp atmosphere.

Low-quality paints can get worse with time and start peeling off when exposed to moisture and humidity. 

Make sure to use good-quality products in your bathrooms because it can cause you repairing or damage costs if it turns out into a mess.

Use a high-grade sealant or finisher because there are more chances of water damage to the surface.

A fine finisher can make a protective layer on the surface of bathroom countertops and prevent the accumulation of dust and mildew on it.
