How to Paint a Bathroom Ceiling

Painting a bathroom ceiling may seem like a challenging task, but with the right approach and tools, it can be accomplished smoothly. The key to a successful paint job not only involves selecting the appropriate paint type but also prepping the area correctly to ensure optimal results. In this guide, you will learn how to paint your bathroom ceiling with confidence, leaving it looking fresh and clean.

Begin by choosing a mildew-resistant, satin, or semi-gloss paint specifically designed for bathrooms. These types of paints are more durable and easier to clean, making them ideal for high-moisture environments like bathrooms. Before starting the painting process, it's essential to properly prepare the room and the ceiling to avoid common pitfalls, which may include removing dust, grime, and any mold or mildew stains present.

Preparing the Bathroom

Before you start painting your bathroom ceiling, it's essential to gather all the necessary tools and materials. You'll need a paint roller, paintbrushes, a clean cloth, a bucket, and sandpaper with 150 grit. Also, make sure you have a ladder that will allow you to reach the ceiling safely.

Once you have gathered all the required tools and materials, you need to prepare the bathroom for the paint job. Start by removing all fixtures, such as light bulbs, shower curtains, and any other items that might get in the way or become damaged during the painting process.

Next, clean the ceiling thoroughly to remove any dust, mildew, and dirt. You can use a mixture of vinegar and hydrogen peroxide to effectively clean and kill any mold or mildew present. Allow the ceiling to dry completely after cleaning.

To ensure a smooth paint application, use sandpaper to gently sand the entire surface of the ceiling. This will help create a good base for the paint to adhere to. Wipe the ceiling with a clean cloth to remove any sanding residue. If there are any cracks or holes in the ceiling, use a suitable filler to patch them up before painting.

Lastly, don't forget to cover the floor, bathtub, sink, and other surfaces with drop cloths or plastic sheeting to protect them from paint splatters. Now your bathroom is all set for a fresh coat of paint on the ceiling!

Clearing Space


Before starting your DIY bathroom ceiling painting project, it is essential to clear the space of any furniture. Remove as much furniture as possible from the room, especially large items like cabinets and shelves, to avoid potential paint splatters and spills. If any furniture is too heavy or cannot be removed, protect them with canvas drop cloths to keep them clean and safe from paint.


Next, pay attention to the bathroom fixtures such as lighting, mirrors, and towel racks. To protect these fixtures from accidents, cover them with careful precision and tape edges where possible to prevent paint from seeping through. It's better to spend extra time on this step now than to deal with difficult cleanups later.

When setting up your workspace, ensure proper safety measures are in place. Use a step ladder to reach the ceiling comfortably and avoid straining or overextending yourself. Ladders also provide a more stable base than a wobbly chair or unstable surface.

Lastly, don't forget to lay drop cloths on the floor to protect your bathroom tiles from paint spills and splatters. Choose canvas drop cloths for better durability and long-term use, as they are less likely to tear than plastic counterparts.

By following these steps and preparing your bathroom space, you can confidently and efficiently paint your ceiling without the worry of damage to your fixtures and furniture.

Cleaning and Repairing

Before painting your bathroom ceiling, it is crucial to clean and repair the surface for a smooth and long-lasting finish. This includes mold and mildew removal, sanding, and caulking.

Mold and Mildew Removal

Mold and mildew can cause health problems and also compromise the paint adhesion to the ceiling. You can easily remove these growths by using a homemade solution of equal parts water and bleach. Wearing rubber gloves and protective eyewear, gently scrub the solution onto affected areas using a soft brush or sponge. Let it sit for 15 minutes before rinsing with clean water. Ventilate your bathroom properly by opening windows and doors to speed up the drying process.


After addressing mold and mildew, use an orbital palm sander to remove any remaining peeling paint from your bathroom ceiling. Sand the entire ceiling lightly with medium-grit sandpaper to create a smooth and even surface for the paint to adhere to. Always wear a dust mask to protect yourself from inhaling dust and debris during sanding.


Inspect your bathroom ceiling for gaps or cracks and apply caulk to seal and repair these areas. This will not only create a seamless surface but also prevent moisture from seeping in and causing damage in the future. Using a caulking gun, apply a thin bead of paintable caulk along the gaps or cracks. Smooth the caulk with a wet finger or a damp sponge for a professional finish. Allow the caulk to dry completely as per the manufacturer's instructions before proceeding with painting.

Masking and Protecting Surfaces

Painter's Tape

When painting a bathroom ceiling, it's essential to properly mask and protect surfaces to get a professional-looking result. Start by applying painter's tape along the edges of the ceiling, where it meets the walls. This will create a clean line between the ceiling and wall paint colors. Ensure the tape is pressed firmly against the edge, so paint doesn't seep underneath. To protect the baseboards, apply painter's tape to the top edge, close to where they meet the wall.

Covering Tiles and Fixtures

For protecting tiles and bathroom fixtures, use plastic sheeting or drop cloths. Cut the plastic sheeting to fit and cover the tiles, then secure it with painter's tape. Be careful not to apply tape directly to the tile surface, as it may leave a residue. Fixtures such as sinks, toilets, and bathtubs should be covered with drop cloths or plastic sheeting, secured with tape if necessary. These precautions will help ensure that your bathroom surfaces are protected from paint splatters and drips while you paint the ceiling.

Remember to keep the room well-ventilated during the painting process, and allow for ample drying time before removing the masking materials and using the bathroom again. By following these steps, you'll be able to paint your bathroom ceiling with confidence and achieve a clean, professional finish.

Choosing the Right Paint

Primer Considerations

Before you begin painting your bathroom ceiling, it's important to select an appropriate primer for the job. Considering the likelihood of moisture and mold, a stain-blocking primer is an essential choice for bathroom surfaces, as it helps prevent stains from seeping through the paint. If mold is already present on the ceiling, you'll want to choose a primer specifically designed to kill mold, like Rust-Oleum Mold Killing Primer.

Bathroom Ceiling Paint

When selecting paint for your bathroom ceiling, it's crucial to account for the moisture and humidity levels this space experiences. Interior latex paint is an excellent choice, as it's water-based and provides good adhesion to damp surfaces.

There are three common finishes to choose from when painting your bathroom ceiling: flat, gloss, and semi-gloss. Here's an overview of each type:

  • Flat paint: While this finish provides a smooth, low-reflective surface, it's not the best option for bathroom ceilings, as it doesn't hold up to moisture well.
  • Gloss paint: This highly reflective finish is durable and resists moisture, making it an ideal choice for bathroom ceilings. Refer to this article for more information on using gloss paint in your bathroom.
  • Semi-gloss paint: A middle ground between flat and gloss finishes, semi-gloss paint offers durability and a moderate shine. It's also resistant to moisture and mildew, as mentioned in this source. This finish is best suited for bathroom ceilings, as it can withstand humidity while hiding some surface imperfections.

In summary, when painting a bathroom ceiling, it's essential to choose a stain-blocking primer that tackles mold and an interior latex paint with a gloss or semi-gloss finish to prevent moisture damage. Following these guidelines will ensure a professional-looking result that lasts.

Paint Application

Tools and Techniques

Before starting, make sure you have the necessary tools: a 2½-inch angle sash brush, a nine-inch roller, a roller cover, an extension pole, and a paint tray. If you don't have a ladder to reach the ceiling, you'll need to purchase one as well.

When painting a bathroom ceiling, it's essential to maintain a wet edge to achieve a consistent finish. Work in sections of about 5 or 6 ft. square. Move quickly from one section to another to ensure the paint along the edge doesn't dry before you start painting the adjacent area.

Cutting In

Begin by cutting in the edges of your bathroom ceiling. This process involves using a brush to paint a thin line along the perimeter of the ceiling where it meets the walls, around light fixtures, and any other obstacles. Use a 2½-inch angle sash brush to carefully apply the paint along the edges, taking your time to ensure a clean line. Be sure to maintain a wet edge as you cut in to prevent noticeable lap marks.

Roller Painting

Next, use a nine-inch roller attached to an extension pole to paint the main areas of the ceiling. Start by loading the roller with paint and removing excess paint by rolling it back and forth in the paint tray. Begin rolling the paint onto the ceiling, starting near the area you've cut in. Use a W or M pattern to ensure even coverage and prevent lines from forming.

For the best results, overlap each pass of the roller and work quickly to maintain a wet edge. If you notice any drips or uneven patches, smooth them out immediately with the roller before moving on to the next section. Continue this process until your entire bathroom ceiling is covered.

Finishing Touches

After applying the first coat of paint to your bathroom ceiling, it's time to add the final touch-ups to ensure a professional and long-lasting finish. In this section, we will discuss three important steps: applying a second coating, peeling off painter's tape, and reinstalling fixtures.

Second Coating

To achieve a smooth, even appearance, it's essential to apply a second coat of ceiling paint. Wait for the first coat to dry completely, which may take a few hours or overnight, depending on the interior latex paint you're using. A second coat of paint provides better coverage and helps create a more uniform finish, particularly if you were covering a dark or black ceiling. Ensure each coat is thin and even to avoid drips and uneven application.

Peeling Off Painter's Tape

Once the second coat is dry, carefully remove the painter's tape along the edges of your ceiling. This step should be done slowly to ensure a sharp, clean line between the ceiling and your walls. Peeling off painter's tape at an angle helps in avoiding damage to the paint on walls or the ceiling.

Reinstalling Fixtures

Lastly, reinstall any light fixtures, vents, or other accessories you removed before painting your bathroom ceiling. Be sure to handle these items carefully to avoid scratching or damaging the freshly painted surface.

By following these steps and using a high-quality latex paint primer when necessary, you'll achieve a durable and beautiful finish for your bathroom ceiling. Your newly painted ceiling will not only protect against moisture but also create a fresh ambiance in your bathroom for years to come.

Additional Tips

Working with Textured Ceilings

If you're dealing with a textured ceiling, you need to take some precautions. First, make sure the texture is clean and free from dust or debris. You may want to use a soft brush or vacuum with a brush attachment to gently clean the surface. When selecting paint, consider using a semi-gloss finish. This will make it easier to clean and maintain the ceiling in the future.

Ceiling Painting Tips

To ensure a professional-looking result when painting your ceiling, follow these tips:

  • Remove as much furniture from the room as possible, and cover any remaining items with drop cloths or blankets.
  • Before painting, prep the ceiling by removing any dust or grime. This can be done using a long-handled duster or a vacuum with an extension hose and brush attachment.
  • Choose a quality paint that is specifically designed for bathrooms, as it will have mold-inhibiting agents and a moisture-resistant surface.
  • Use a ladder that allows you to safely reach the ceiling, and always practice ladder safety.
  • Begin painting with a paintbrush to cut in around the edges, then switch to a paint roller for the main surface of the ceiling.

Painting Alongside Exhaust Fan

When painting around the exhaust fan, it is essential to exercise caution. Turn off the fan's power and remove the fan cover. Tape around the edges of the fan housing to protect it from paint. When painting the ceiling around the fan, use a smaller brush for precision. Remember to clean the fan cover before reinstalling it after the paint has dried.

By following these additional tips and maintaining a confident, knowledgeable, and neutral tone, you can ensure a successful bathroom ceiling painting project.


When painting your bathroom ceiling, it's essential to take into account the cost of materials and equipment needed for the task. Investing in high-quality paint and paint rollers is crucial for a long-lasting finish on your bathroom ceiling. Remember that you might also need to spend around $50 to $100 for a ladder, depending on the quality.

Before starting the painting process, make sure to prep your bathroom by removing any items and fixtures that could get in the way, such as towel racks. You should also cover the toilet, baseboard, and any other surfaces you want to protect from paint splatters.

When working in a confined space, ensure that you have ample room for painting by placing your paint and supplies near you, but not in the workspace. Moreover, using an extension handle for your paint roller can provide ease and flexibility while painting your bathroom ceiling.

In summary, by considering factors like cost, choosing the right materials, and prepping the bathroom, you can achieve a professional and durable paint job on your bathroom ceiling. Your efforts will result in a well-maintained space that's resistant to mildew and other water damage. Good luck, and happy painting!
