Spaces around any appliance or fixture that uses water or creates water through condensation (like an air conditioner or refrigerator) might be worth using mold-resistant drywall when practical. It's also worth considering using mold-resistant drywall in basements or crawl spaces where mold is likely to grow.
You should use the mold resistant drywall/Sheetrock board. The room will have a high moisture content in the air due to steam, so anything you can do to inhibit mold growth is best. Also think about a mold resistant paint.
phasing out greenboard
This relatively new addition to the drywall market is gradually replacing green board because it's suited to the same tasks but even more water- and moisture-resistant than green board. Paperless drywall consists of a water-resistant gypsum core and a fiberglass (rather than paper) backing.
Even if your drywall contains moisture- and mold-resistant properties, it can still be at risk for mold growth if not for careful design, proper construction, and thorough maintenance. These factors are meant to manage moisture, which is the only variable that can be controlled within the construction environment.

Greenboard costs about 20% more than regular, conventional drywall. However, depending on your project, greenboard might be worth the extra expense because it could prevent water damage and mold and mildew growth down the line.
Once complete, the surface is ready for painting or another finish. Since mold-resistant drywall is generally installed in humid locations, the best surface finish is with wall primer and paint that have good mildew and mold resistance.
The faster the drywall is dried, the better chance it has of being salvaged. If drywall remains wet for an extended period (typically more than 48 hours), the likelihood of Mold growth increases, making replacement the safer option.
As you are probably aware, traditional drywall has paper on both sides. That paper is the usual culprit when it comes to taking up water, and the water that is soaked up by the paper is where the mold will begin to grow. With mold-resistant drywall, the paper is not used.

A Level 5 drywall finish involves an additional skim coat of joint compound over the entire surface, providing the highest-quality finish. This level is essential for areas with critical lighting conditions, where the appearance of the wall is paramount. It can deliver a smooth, uniform surface.
