Painting a bathroom is not as simple as painting other rooms in your home. The space is frequently exposed to humidity and water, requiring specialised paint to prevent mould and discolouration. The type of paint you choose should be labelled for kitchens and bathrooms, as this type of paint repels mould and mildew. For added protection, opt for a semi-gloss finish, as these paints cure to a harder finish, making them more moisture-resistant. It is also important to ensure your bathroom has good ventilation, such as a working window or a powerful extractor fan. Once you have painted your bathroom, it is recommended to wait at least 48 hours before taking a shower.

Recommended waiting time before showering after painting
Painting a bathroom can be tricky due to its high moisture content. It is important to wait for the paint to dry before showering, as reintroducing moisture can interfere with the curing process. The amount of time you should wait depends on several factors, including the size of the bathroom, the ventilation, the number of coats applied, and the type of paint used.
If your bathroom has poor ventilation and high humidity, it is recommended to wait at least 7 days before showering after painting. This will ensure that the paint is fully cured and reduce the risk of staining or peeling. In one case, a user reported that their bathroom ceiling began to stain a few months after painting because they did not wait long enough for the paint to cure.
For bathrooms with good ventilation and low humidity, you may be able to shower after 48 hours. This will allow the paint to dry sufficiently so that moisture from the shower will not interfere with the curing process. However, it is important to note that this is not a full cure, and the longer you wait, the better.
To speed up the drying process and reduce humidity, you can use an exhaust fan during and after showering. Keeping the bathroom door open can also help to increase air circulation and reduce moisture buildup. If possible, avoid taking hot and steamy showers for the first week after painting, as this can cause surfactant leaching and slow down the curing process.
The type of paint used can also affect the recommended waiting time. Latex paint, for example, can take up to a week or even a month to fully cure. It is important to follow the manufacturer's instructions and recommendations for the specific paint you are using.

How to prevent paint peeling
Painting a bathroom can be a tricky endeavour due to the high humidity and moisture levels. If you've recently painted your bathroom, it is best to wait at least 48 hours before taking a shower, to ensure the paint has dried adequately. In some cases, it may take up to a week for the paint to cure fully, especially if you're using latex paint. If you don't want to wait that long, opt for a shorter, warm shower instead of a long, hot one, and ensure the bathroom is well-ventilated to prevent the build-up of moisture. Keep the bathroom door open, and use an exhaust fan if you have one.
Now, let's delve into the details of how to prevent paint peeling:
Proper Surface Preparation:
Before painting, ensure the surface is clean, dry, and smooth. Use trisodium phosphate (TSP) or a mild detergent to scrub away any dirt or grime. If the wall was previously painted, strip the old paint and repair any cracks or holes to create a smooth, even surface. Lightly sand the surface, especially if it's wood or drywall, to make it less rough.
Choose the Right Primer:
Primer is essential for a long-lasting paint job. It helps your paint adhere to the surface and prevents peeling, cracking, or flaking. Choose a primer suitable for the surface, such as a masonry bonding primer for CMU walls. If you're painting over an existing coat of paint, use a primer designed for bonding between oil-based and water-based layers if needed.
Invest in Quality Paint:
Using low-quality paint can lead to peeling within a few months or years. Opt for top-quality paint brands to ensure better adhesion and durability.
Avoid Excessive Moisture:
As mentioned earlier, moisture is a significant culprit in paint peeling, especially in humid environments. Ensure your bathroom is well-ventilated, and avoid taking long, hot showers for the first few days after painting.
Remove Painter's Tape Carefully:
When using painter's tape, ensure the paint is fully dry and cured before removing the tape. Pull the tape down early and gently to avoid peeling.
Apply Thin Coats:
Avoid applying paint too thickly. Use thin coats and allow each coat to dry completely before applying the next one. This will result in a better finish and reduce the chances of peeling.
By following these steps, you can significantly reduce the chances of paint peeling in your bathroom or any other space you're painting.

Choosing the right paint for your bathroom
Painting a bathroom requires special consideration when selecting paint. The ideal paint for a bathroom should be moisture-resistant, easy to clean, and durable enough to withstand regular exposure to water and cleaning products.
Moisture resistance is the most important factor when choosing bathroom paint. Without proper protection, walls and ceilings can develop mould and mildew, leading to health hazards and costly repairs. Therefore, it is important to select a paint that can repel water and resist peeling or bubbling when exposed to steam and splashes.
There are several types of paint that can be used in bathrooms, each with its own advantages and considerations:
- Acrylic paint is an excellent choice for bathrooms due to its moisture-resistant properties and quick-drying time. It adheres well to bathroom surfaces and creates a durable finish that can withstand frequent cleaning. Acrylic paint also resists fading and yellowing over time, maintaining its appearance even in high-humidity environments. When selecting acrylic paint, look for formulas designed for high-moisture areas, as these often contain additives that enhance their mould and mildew resistance.
- Latex paint is another popular option for bathrooms as it offers good moisture resistance, is easy to apply, and dries quickly. It provides excellent coverage and is less likely to yellow over time compared to oil-based paints. Choose a high-quality latex paint formulated for high-humidity areas, as these paints often contain additives that enhance their performance in moist environments.
- Oil-based paint is known for its extreme toughness and is typically used for bathroom cabinets or high-traffic door casings. However, it can turn yellow over time and releases high levels of volatile organic compounds (VOCs) during drying. If you choose to use oil-based paint, ensure proper ventilation during and after painting, and be aware that it may require special cleaning solvents and disposal methods.
- High-gloss paint is excellent at repelling moisture and is easy to wipe clean. However, it may not always look aesthetically pleasing on large surfaces like walls. Consider using high-gloss paint on trim or cabinets, while reserving semi-gloss for the walls.
When selecting paint for your bathroom, it is important to consider the space, shine level, and colours. Determine if the surface has been previously painted, as this may affect the type of primer and paint needed. If the surface has a glossy finish, choose a primer that can cover high-gloss surfaces effectively.
Additionally, consider the lighting in the bathroom and whether you have natural light. High-gloss paints can reflect light and create a shiny effect, which some may find unappealing. Satin or semi-gloss finishes can provide a middle ground, offering some shine without being overly glossy.
The colour of the paint can also impact the overall feel and perceived size of the bathroom. Light colours, such as whites, creams, pastels, and light greys, are often recommended, especially for smaller bathrooms, as they can make the space feel larger and brighter. Dark colours can create a cosy, spa-like atmosphere in larger bathrooms but may make smaller spaces feel cramped. If you prefer darker shades, consider using them as an accent wall or pairing them with lighter tones to balance the space.

How to deal with humidity in your bathroom
Painting a bathroom can be a tricky endeavour, especially if you plan on showering in it. The longer you wait to shower, the better. Ideally, you should wait at least 48 hours after painting before taking a shower. This will ensure that the paint has enough time to dry and that the reintroduction of moisture doesn't interfere with the curing process.
Now, if you are dealing with humidity in your bathroom, there are several ways to address this issue:
- Improve ventilation: Keep the bathroom door open while you shower or install a passive ventilation unit. Passive ventilation units are a natural, low-cost method of improving ventilation in your bathroom. They rely on the principle of warm air rising and lower outside pressure sucking out humid air.
- Use an exhaust fan: If you have an exhaust fan, use it during and after every shower to help remove humid air quickly. If you don't have one, consider talking to your landlord about installing one.
- Upgrade your windows: Single-paned windows tend to be colder and create more condensation. Consider upgrading to double-glazed windows to reduce condensation and improve the energy efficiency of your home.
- Wipe down surfaces: After your shower, use a towel, cloth, or squeegee to wipe down tiles, mirrors, windows, and other surfaces where condensation collects. This will help prevent the growth of mold and mildew.
- Hang damp clothes outside the bathroom: Wet clothing and towels can contribute to humidity in the bathroom. Make sure to hang them outside the bathroom to reduce moisture levels.
- Use moisture-absorbing plants: Certain plants, such as the peace lily, can help absorb moisture from the air and reduce humidity levels in your bathroom. Not only do they improve the aesthetics of your bathroom, but they also create a fresher environment and help reduce mold growth.
By following these tips, you can effectively manage humidity levels in your bathroom and create a more comfortable and healthier environment.

How to prepare your bathroom before painting
Painting a bathroom requires more preparation than painting other areas of the home. Bathrooms are small, humid, and full of water from various sources, and they receive lots of heavy use. Here are some steps to prepare your bathroom before painting:
Choose the right paint
Since the bathroom frequently comes into contact with water, it requires a specialised paint to ensure optimal performance. Some paint manufacturers sell what they call "bathroom paint", which has both mould-inhibiting agents and a better surface for resisting moisture. Even if you don't want to buy special bathroom paint, you may want to spend a little bit more on a quality brand of paint. Flat or matte sheens can develop water streaks and are not recommended for bathrooms. Higher gloss sheens tend to do a better job of repelling moisture and debris than flatter sheens, but they do highlight imperfections in the wall. If your wall is rough in spots or has marks you'd like to hide, consider an eggshell finish, which can be wiped clean. If you have drywall in the upper section of the shower or tub stall area, go for higher gloss paint.
Clean the walls
It is crucial to clean the walls before painting. Soap scum around the bathtub and shower can cause your paint job to peel off. Trisodium phosphate, or TSP, is an inexpensive cleaning product that can be used to clean the walls before painting. Mix one part TSP to four parts water, then wipe down your walls with this mixture, followed by warm water, and let them dry completely before painting.
Remove or cover items
Remove switch and outlet plates, mirrors, bathroom exhaust vent grilles, towel racks, and any other items that you can remove relatively easily. If you are not removing your toilet, make sure you have a paintbrush that’s narrow enough to reach behind it and get in all the nooks and crannies. Cover furniture and mouldings to avoid splattering them with paint. For example, you can use old bed sheets or large pieces of plastic to protect your vanity, bathtub and flooring. Secure these coverings with painter's tape to avoid damaging the surface or leaving behind a sticky residue. Tape off the ceiling, trim, bathtub surround, backsplash, and other areas that will not be painted.
Ventilate the room
Bathrooms are constantly exposed to humidity, so it is important to ventilate the room while painting. Keep the doors wide open and use an exhaust fan to keep the room ventilated. If you don't have an exhaust fan or if it doesn't work properly, talk to your landlord about getting one.
