According to Valspar Paint, the best choice for bathroom paint is one with a semi-gloss finish. Forbes expands upon the recommendation by stating that an outdoor paint with a semi-gloss or gloss finish provides the greatest protection for bathroom walls and trim. It is critical that the paint is able to resist the moisture that accumulates on a daily basis.
Bathrooms are one of the most humid rooms in any home due to the moisture that results when water is run for showering and bathing. This makes bathrooms subject to growth of mold and mildew. All surfaces require frequent cleaning to counteract this growth and to eliminate germs that are present from the natural uses of the room. In order to ensure that the walls stay looking beautiful, having a high quality paint that resists mold and mildew while handling intense regular cleaning is essential. Paints with a gloss or semi-gloss finish are capable of doing this better than their flat counterparts.
Painting the cabinetry in a coordinating color with the same finish keeps the entire room clean and attractive. Many paint companies offer a wide selection of colors that are designed specifically to resist mold and mildew and that have an attractive glossy finish when they have dried.
