Pros of Using Exterior Paint in Your Bathroom

Pros of Using Exterior Paint in Your Bathroom

The idea of applying exterior paint in your bathroom might seem unconventional at first. Yet, as you delve into the advantages this type of paint offers, you’ll find it to be a practical and appealing choice.

One of the primary virtues of exterior paint is its resilience against drastic conditions. This paint type is built to withstand harsh weather such as extreme temperatures and heavy rainfalls. It means that high humidity and temperature fluctuations found in bathrooms won’t present a challenge. Your bathroom will maintain its polished, refreshing look for a longer time.

Exterior paints also come with high-quality resistive properties. They’re designed to resist UV rays, mildew, and even fading. As a result, they can handle the consistent moisture and exposure to chemicals from cleaning solutions commonly found in bathrooms. You won’t have to worry about the color fading and the surface developing mildew, thus reducing the frequency of bathroom repaints.

Let’s not forget that exterior paint is ideal for high-traffic areas. With its high durability, it can withstand the everyday wear and tear experienced in bathrooms. No more concerns about your wall paint chipping or peeling off easily.

Another appealing feature of exterior paint is its diverse range of colors and finishes. Just because it’s manufactured for the outdoors doesn’t mean it is available in limited color options. In fact, you’ll find a wide spectrum of shades to choose from, adding a unique touch to your bathroom aesthetics.

It’s also worth noting that exterior paints generally have better coverage compared to their interior counterparts. If you are seeking to cover dark walls or stains, an exterior paint might be your best bet. It provides an opaque finish in fewer coats, saving you time and extra layers of paint.

Pleasing aesthetics, enriching durability, and practical benefits all underline the major advantages of using exterior paint in your bathroom. While there are pros and cons to every decision, these factors offer compelling reasons to consider exterior paint during your next bathroom renovation.

Cons of Using Exterior Paint in Your Bathroom

While exterior paint has its definite perks, it’s essential to consider the other side of the coin. Yes, there certainly are downsides when you use exterior paint indoors, especially in your bathroom.

Odor and Chemicals: The most noticeable con you’ll likely encounter is the robust odor that often accompanies exterior paint. It’s formulated for outdoor use, meaning it contains chemicals designed to withstand the elements. Those same chemicals can produce strong aromas which may make it uncomfortable for indoor use. Due to these chemicals, exterior paints have a higher VOC (Volatile Organic Compounds) content, substances that evaporate at room temperature and may pose health risks.

Longer Drying Time: Another aspect to look into is the longer drying time. Typically, exterior paints take more time to dry than interior variants. While this might be fine when you are sprucing up your porch, it’s not the most convenient when it comes to a high-traffic area like your bathroom.

Surface Compatibility Issues: Lastly, keep in mind that exterior paints are designed to adhere to traditional outdoor surfaces, such as wood, metal, and masonry. This might lead to less-than-perfect results when applied to the common interior materials like drywall and plaster.

However, it’s not all doom and gloom. Note that these potential challenges don’t necessarily rule out exterior paint as an option. By taking careful steps, it’s entirely possible to enjoy the superior durability and color variety of exterior paint, even in the humid confines of your bathroom. Evaluate these factors and make an informed decision that fits your needs.

Considerations Before Using Exterior Paint

In weighing the benefits of exterior paint against its downsides for your bathroom, it’s imperative to consider a few factors. These include room ventilation, surface preparation, and the type of the chosen exterior paint. Let’s delve into these key aspects to guide your renovation decision making.

When it comes to ventilation, exterior paints tend to have strong odors due to their chemical components. These smells might feel overpowering in a small, confined bathroom without standard ventilation. So think about your bathroom’s ventilation to decide whether it can tolerate the pungent smell typical of exterior paints.

Next let’s tackle surface preparation. Exterior paints are designed to adhere to robust, textured surfaces like bricks and siding. Your bathroom’s interior surfaces might pose compatibility challenges that require specific preparation steps. The simpler the preparation, the better it becomes for you. Now, you don’t wish for your bathroom project to stretch into an all-day affair, do you?

Lastly, considering the type of exterior paint is significant. If you’re thinking about high gloss paint, it might not blend well with your bathroom’s interior surfaces. Some types like latex-based exterior paint can bring about longer drying times compared to interior paints. Yet, it’s these types that often offer an array of vibrant color options and improved durability.

At this juncture, you might be asking – is there a silver lining amidst these concerns? Fret not. With careful planning and adequate preparation, exterior paint can still make a tasteful addition to your bathroom renovation. A careful balance of the essentials ensures that you reap the advantages without falling victim to the pain points.

Alternative Paint Options for Bathrooms

Alternative Paint Options for Bathrooms

So, you’ve explored the idea of using exterior paints in your bathroom and familiarized yourself with the considerations involved. Now you might be wondering, what are your other options? Thankfully, there are many great alternatives in the market that are specially designed for use in wet, humid environments like your bathroom.

One popular choice is mold-resistant paint. This type of paint contains additives that inhibit mold growth. It’s particularly useful in bathrooms with poor ventilation where mold is a common problem.

Kitchen and bath paints are another excellent option. These are designed to withstand high humidity levels and resist mildew growth. Kitchen and bath paints are usually highly washable, which is great for cleaning up soap scum and water spots.

Looking for a stylish yet practical option? Semi-gloss or high-gloss paints could be your answer. These types of paint are high in durability and moisture resistance. Plus, they are usually easy to clean, making them a perfect fit for high-traffic areas in the bathroom.

Consider oil-based paints if you’re dealing with old, stained, or damaged surfaces. This type of paint is highly resilient and great at covering up imperfections. However, it’s important to note that oil-based paints often require more ventilation time than water-based paints.

Lastly, for someone eco-conscious, consider low VOC paints. Volatile Organic Compounds (VOCs) are chemicals found in many paints, including some exterior options. They can off-gas into the air and cause health problems. Low VOC paints help minimize these risks while also providing good moisture resistance.

Whichever type of paint you choose, remember to always prepare your surface properly and ventilate your room during and after painting. Practical, cost-effective, and safe alternatives to using exterior paint in your bathroom are out there. It’s just a matter of picking the one that best fits your specific needs and style preferences.


So, you’ve pondered the idea of using exterior paint in your bathroom. But remember, it’s crucial to consider ventilation, surface prep, and paint type. While exterior paint might seem like a viable option, there are safer and more practical alternatives tailored for wet environments. From mold-resistant to eco-friendly low VOC paints, you’ve got plenty of options to enhance your bathroom’s style and durability. Don’t forget the importance of proper surface preparation and ventilation to ensure a successful paint job. Choose wisely, and you’re sure to get a bathroom that’s not just stylish, but also safe and long-lasting.

1. Can exterior paint be used in a bathroom?

2. What kind of paint should I use in a bathroom?

Select paint designed for wet and humid environments to prevent peeling and mold issues. Options include mold-resistant paint, kitchen and bath paints, and semi-gloss or high-gloss paints. Those with damaged surfaces might consider oil-based paints.
