Choosing the best mildew-resistant paint for a bathroom starts with matching the finish and package size to your project. The options below include purpose-made interior paints and one waterproofing paint intended for basement walls. Keep in mind that mildew-resistant paint protects the paint film; it does not fix leaks, poor ventilation, or mildew growing behind a surface.

Our Picks: Best Mildew Resistant Paint For Bathroom reviews
1. Zinsser PERMA-WHITE Eggshell: Best All-Around Quart
This interior paint is a practical starting point for a bathroom refresh, especially if you need a smaller amount. It comes in an eggshell white finish and a quart-size container. Its self-priming formula is designed to adhere without sanding, which can simplify preparation on suitable surfaces.
The paint film is described as mold- and mildew-proof, with a five-year guarantee. It is also made to resist dirt and moisture, and the finish can be washed and scrubbed with soap and water. The product description makes an important distinction: its mildewcide helps prevent mold and mildew on the paint film only. It is not a treatment for mold inside a wall or for ongoing moisture problems.
Compared with the satin and semi-gloss choices, eggshell may suit shoppers who prefer a less glossy look. The main trade-off is that this quart is not the best package size for a large room. You will also need to address leaks and moisture sources separately rather than relying on paint alone.
Pros:
- Self-priming formula requires no sanding, according to the product description.
- Washable and scrubbable with soap and water.
- Eggshell finish in a quart-size can.
- Paint-film mildew protection is backed by a five-year guarantee.
Cons:
- The mildewcide protects the paint film only.
- A quart may not be enough for a larger bathroom project.
Verdict: Choose this one for a smaller bathroom job if you want an eggshell finish and washable paint with clearly stated paint-film protection.
2. Zinsser PERMA-WHITE Satin Gloss: Bathroom-Focused Quart
This quart-size Zinsser paint is specifically labeled as mildew-proof bathroom paint. The product name identifies a satin gloss finish, making it a relevant option for shoppers who want something glossier than eggshell without choosing the semi-gloss gallon.
The supplied product details provide little information beyond the name and package size, so there is less to compare here than with the PERMA-WHITE eggshell and semi-gloss options. Confirm the finish and label directions on the product listing before ordering, particularly if matching an existing paint sheen matters to you.
Its quart format may be convenient for a small area or touch-up project. On the other hand, shoppers who want detailed product specifications—such as coverage, dry time, or cleaning instructions—may prefer a listing that provides those details. This item is listed as available in the supplied product data, but listing status can change.
Pros:
- Labeled for bathroom use.
- Quart-size package may suit smaller projects.
- Satin gloss finish offers an alternative to eggshell and semi-gloss.
Cons:
- The supplied description offers few details beyond the product name.
- Check the listing for finish and application information before buying.
Verdict: Consider this quart if a bathroom-labeled satin gloss paint fits your project, but verify the listing details before you commit.
3. Zinsser WaterTite: Waterproofing Paint for Basement Walls
WaterTite is different from the other picks: it is described as waterproofing paint for basement wall protection, rather than a general bathroom interior paint. The latex-based formula is designed to resist water pressure, and its product description lists a 15-year waterproof guarantee and a 10-year mold- and mildew-proof paint-film guarantee.
The paint is described as bright white with a smooth, non-gritty finish. It is intended for dry walls and can be applied with a brush or roller. The low-odor formula and soap-and-water cleanup may be useful features for a wall-protection project, but its basement focus makes it a less direct fit for ordinary bathroom repainting.
Do not treat waterproofing paint as a substitute for finding the source of a leak or fixing a moisture problem. The supplied data also lists this product as unavailable, so it may not be an option to purchase through the listing at the moment reflected by that information.
Pros:
- Designed for waterproofing and basement wall protection.
- Described as resisting water pressure.
- Low-odor formula with soap-and-water cleanup.
- Includes separate waterproofing and paint-film guarantees in the product description.
Cons:
- Its stated use is basement wall protection, not routine bathroom painting.
- Listed as unavailable in the supplied product data.
Verdict: Look at WaterTite for a basement waterproofing job, not as your default choice for bathroom walls.
4. Zinsser PERMA-WHITE Semi-Gloss: Best for a Larger Interior Project
This gallon-size PERMA-WHITE paint is intended for interior spaces that include bathrooms, kitchens, basements, closets, and laundry rooms. Its semi-gloss finish is washable, and the product description lists coverage of 300–400 square feet per gallon. That makes it the clearest match here for someone planning a larger painting job.
The paint is described as self-priming and able to adhere without sanding. It dries to the touch in 30 minutes, according to the supplied product details. These specifications can help with planning, but follow the container instructions for surface preparation and recoating rather than assuming that touch-dry means ready for another coat.
Compared with the quart options, this gallon offers more paint and stated coverage information. The trade-off is that the supplied data lists it as unavailable. Check the product listing for current status, and consider another available PERMA-WHITE option if you need paint sooner.
Pros:
- Gallon size for a larger interior project.
- Listed coverage of 300–400 square feet per gallon.
- Washable semi-gloss finish.
- Self-priming formula and 30-minute touch-dry time, per the product description.
Cons:
- Listed as unavailable in the supplied product data.
- Semi-gloss may not suit shoppers who prefer a lower-sheen finish.
Verdict: This is a strong format and finish match for a larger bathroom or interior project if the listing becomes available and semi-gloss suits your taste.
5. Rust-Oleum Zinsser PERMA-WHITE Satin: Multi-Can Pack
This listing is for six quart cans of Zinsser PERMA-WHITE satin interior paint, so it is aimed at a project that needs more than one quart. The product description calls the finish washable, scrubbable, stain-resistant, and moisture-resistant. It also identifies the formula as water-based and low-odor.
The paint is described as self-priming and able to stick without sanding. It can be tinted to off-white, pastel, and medium colors, which gives it more color flexibility than a product listed only as white. The multi-can format may be more paint than you need for a small bathroom, so estimate your project needs before choosing it.
Like the other PERMA-WHITE options, the product is intended to protect the paint film, not solve moisture problems inside the room or wall. The supplied data lists this pack as unavailable, which limits its usefulness unless the listing status changes.
Pros:
- Six quart cans for projects that require multiple containers.
- Washable, scrubbable, stain- and moisture-resistant finish, per the product description.
- Water-based, low-odor formula.
- Tintable to off-white, pastel, and medium colors.
Cons:
- A six-can pack may be excessive for a small bathroom.
- Listed as unavailable in the supplied product data.
Verdict: Consider this pack for a larger project needing several quarts and a tintable satin finish, but check availability and quantity before buying.
How to Choose Mildew-Resistant Paint for a Bathroom
Look for protection that matches the problem
Check whether the paint is intended for interior rooms such as bathrooms and what its mildew claim actually covers. For example, the PERMA-WHITE eggshell description says its mildewcide prevents growth on the paint film only. That does not mean it removes existing mold, seals a leak, or stops moisture from entering through a wall.
Pick a finish you can live with
These options include eggshell, satin, and semi-gloss finishes. The right choice depends on the look you want and the finish already used nearby. If you are unsure, compare the product label and listing carefully; a finish name alone does not tell you every detail about cleaning or application.
Estimate how much paint your project needs
Choose a package size based on the area you plan to paint. The options here range from a quart to a gallon and a six-quart pack. The gallon PERMA-WHITE listing gives coverage of 300–400 square feet per gallon; for products without stated coverage, use the label or listing rather than guessing. Buying a pack that is too large can leave you with more paint than the job requires.
Check the application and cleanup details
Self-priming claims can simplify preparation, but they do not remove the need to follow the product directions for your surface. Look for clear guidance on surface condition, application, drying, and cleanup. The supplied descriptions mention soap-and-water cleanup for some products, while the other listings provide fewer application details.
Fix moisture before painting
Paint is a finish, not a repair for plumbing leaks or persistent dampness. Find and address the source of moisture before repainting, and remove any existing growth using appropriate methods for the surface. This helps you avoid covering up a problem that may return beneath or around the new coating.
Confirm that the listing fits your project
Product names can sound similar while the intended uses differ. WaterTite is described as basement wall waterproofing paint, while the PERMA-WHITE options are listed for interior use, including bathrooms. Also check the listing for current availability, finish, package size, and any details missing from the product information here.
Frequently Asked Questions
Does mildew-resistant paint prevent mildew throughout a bathroom?
No. The PERMA-WHITE eggshell description says the mildewcide prevents mold and mildew on the paint film only. Paint does not address moisture sources or growth behind a wall.
Which option is the best fit for a small bathroom project?
The Zinsser PERMA-WHITE eggshell quart is a straightforward option for a smaller job, with a washable finish and stated paint-film protection. The satin gloss quart is another bathroom-labeled choice, but its supplied description includes fewer details.
Which paint option includes stated coverage information?
The Zinsser PERMA-WHITE semi-gloss gallon lists coverage of 300–400 square feet per gallon. Check the container directions for the exact needs of your surface and project.
Is WaterTite the same as bathroom paint?
No. The supplied description presents WaterTite as waterproofing paint for basement wall protection. It is not the most direct choice for a routine bathroom repaint.
Can mildew-resistant paint cover existing mold?
Do not rely on paint to cover or remove existing mold. Address the growth and the moisture source before painting, and follow appropriate guidance for the surface and extent of the problem.
Do I still need to prepare the surface if the paint is self-priming?
Yes. Self-priming describes a product feature, but you should still follow its label directions and make sure the surface is suitable for painting. The product information does not replace surface-specific preparation instructions.
Which option should I choose if I want a glossier finish?
The listed choices include satin gloss and semi-gloss options. Compare the exact finish on the product listing, since a glossier look may not match every bathroom or nearby painted surface.
Final Recommendation
For most small bathroom painting jobs in this group, the Zinsser PERMA-WHITE Eggshell quart is the clearest choice because its supplied description spells out the finish, washable surface, self-priming formula, and paint-film mildew protection. Choose the semi-gloss gallon for a larger project if it is available and its sheen suits your room. Whichever paint you select, deal with leaks and persistent dampness before opening the can.
