When it comes to picking the best waterproof paint for bathrooms, there are a few key factors to consider. The high humidity and potential for water splashes in bathrooms means you need a paint that can stand up to moisture without peeling, fading or growing mold. At the same time, you want an attractive finish that is easy to clean and resists stains. The good news is that today’s water-based latex paints are formulated to be extra durable in wet environments. Here’s an overview of what to look for when shopping for the best bathroom paint.

Consider Acrylic or Epoxy Paint
For the ultimate in waterproof performance, choose an interior paint labeled as “100% acrylic” or an epoxy paint. Acrylic paints are made with acrylic resins that form a plastic-like coating able to withstand moisture. The higher the acrylic content, the more water-resistant the paint. Epoxy paints offer an even tougher, industrial-grade finish that resists moisture, chemicals and abrasion. However, epoxy paints contain solvents and require careful prep work for proper adhesion.
Evaluate Finish Options
In addition to the binder or resin that makes the paint waterproof, also evaluate the sheen or finish. Bathrooms do best with paints that have a gloss, semi-gloss or satin finish rather than a flat finish. Glossier paints are more stain resistant and easier to clean. Satin offers a nice compromise between the durability of a gloss and the subtle reflectance of a flat. Semi-gloss is durable, but the high shine may show more flaws in the wall surface.
Look for Mold and Mildew Resistance
Many quality bathroom paints also include additives to inhibit mold and mildew growth. With the warm, humid conditions found in bathrooms, this is a useful feature. Check product details for information about mold and mildew resistance. Some acrylics contain antimicrobial additives. For severe mold issues, specially formulated bathroom paints have added biocides to prevent mold and mildew growth.
Pick Bright White for a Clean Look
Crisp bright white is a popular color choice for bathrooms because it makes the space look clean and fresh. An ultra-bright white like Swiss Coffee OC-45 provides a fresh backdrop. If pure white seems too stark, soften it with an undertone like antique white, which has a slight yellow cast, or lunar white, with a hint of gray-blue. Just steer clear of darker beiges, which can show dirt and stains.
Use 100% Silicone Caulk at Seams
While you’ll get the most waterproof results from the paint itself, also caulk around tile, the tub, sinks and other bathroom fixtures with 100% silicone caulk. Silicone caulk adheres well to different surfaces and flexes to match their movements. It’s waterproof for filling any gaps where moisture could seep behind your new paint.
Prep Surfaces Properly
Even the most waterproof paint can’t adhere and perform properly without good surface prep. Start by cleaning surfaces to remove any dirt, soap buildup, grease and other residues. Scrub moldy areas with a bleach solution. Fill any holes or cracks wider than a hair with caulk or spackle. Sand glossy surfaces dull for the best adhesion. Prime new drywall or bare wood. A coat of primer seals surfaces so the finish paint bonds tightly.
Apply Two Coats
Always follow the manufacturer’s recommended application instructions, including proper drying time between coats. In most cases, you’ll get the best results from two coats of waterproof bathroom paint. Use a premium roller with a high-quality synthetic nap. Apply in a V or W pattern without overspreading. Let the first coat dry completely before adding the second for maximum moisture resistance.
Consider Cleanup Requirements
Check whether your paint choice requires soap-and-water cleanup or solvents like mineral spirits. Water-based acrylics clean up with water, while epoxy may involve solvents. Clean paintbrushes and other tools promptly after painting before the paint has a chance to dry.
Review Coverage Rates
The coverage or spread rate of the paint determines how much you’ll need to buy. Higher-end acrylics and epoxies provide more coverage per gallon. Check the manufacturer’s estimates for square footage per gallon. Add 10-15% more paint for the first coat and textured surfaces.
Buy From a Trusted Brand
Stick with top brands of interior paint sold at hardware stores and paint specialty shops. Brands like Behr, Benjamin Moore, Sherwin-Williams and Valspar offer quality bathroom paint options. Ask a sales associate for recommendations if you’re unsure which product suits your needs.
Protect Floors and Furnishings
No matter how careful your paint job, drips and spatters can happen. Cover bathroom floors with plastic drop cloths taped down along the edges. Remove toilet paper holders, towel bars and other fixtures or cover them with painter’s tape and plastic. Hang drop cloths over doorways as added protection.
Ventilate the Room
Proper ventilation is key when painting bathrooms. If possible, open a window and run a fan to circulate fresh air and dry the paint faster. Alternatively, keep the bathroom door open with a fan drawing air through the room. Don’t forget to turn on the bathroom fan as well if one is present.
Let Paint Dry Completely
Most quality bathroom paints are dry to the touch within an hour. However, paint reaches full cure and maximum durability after one to two weeks. Don’t scrub or clean painted surfaces until the paint has had ample time to fully cure.
Conclusion
With the right paint and prep, you can transform your bathroom into a bright, waterproof space. Look for a top-quality 100% acrylic or epoxy paint to resist moisture and mold. A bright white with a semi-gloss or satin sheen makes for the easiest-to-clean finish. Always properly prep surfaces and apply two coats of paint for optimal results. With a little time and effort, you can give your bathroom an updated look that stands up to the humidity.
