Frequently Asked Questions

How much paint do I need for a bathroom?

A standard 8x6 bathroom with 8-foot ceilings needs about 1 gallon of paint for two coats on the walls. Smaller powder rooms may need less. Always buy a little extra for touch-ups in high-moisture areas.

What type of paint is best for bathrooms?

Moisture-resistant paint with a semi-gloss or satin finish is best for bathrooms. These finishes resist mildew growth and are easy to clean. Look for paints labeled "kitchen and bath" for built-in mildew protection.

Do I need special primer for bathroom walls?

A moisture-blocking primer is recommended for bathrooms, especially if there are signs of water damage, mildew, or you are painting over dark colors. PVA primer works well on new drywall in bathrooms.
