Finish is key.

Any bathroom renovation is rife with opportunities for mistakes—don't let your choice of wall paint be one of them.

When picking out wall paint for your bath, you have so many options in regards to brand, hue, and finish. The paint world is your oyster, but there's one essential thing to remember: Of all your choices, the paint finish is the most important.

Why finish? Because few rooms produce as much dampness as the bath. The widespread consensus is that paints with shiny finishes are both easier to keep clean and more resistant to moisture, mold, and mildew than flat finishes. That's why paints with shinier finishes are better choices for walls in the bath, a space notorious for the amount of moisture—and potential mold and mildew—it generates. The mistake, then, is choosing a flat finish for your bathroom walls.

In terms of the actual paint finishes, Consumer Reports recommends using either satin or semi-gloss. They argue, "Satin is more durable and shinier than eggshell and is ideal for a bathroom. It's also easy to clean. Use it for the walls, ceiling, and even the trim, because many satin finishes are tougher than they once were. Semi-gloss is even tougher and a cinch to clean. It can be used on the walls, ceiling, trim, and vanity—if you don't mind a shinier look."
