Can moisture resistant drywall be used in bathroom ceiling?

Yes, moisture-resistant drywall, often referred to as green board, can be used on bathroom ceilings. It's designed to withstand higher humidity levels than standard drywall, making it suitable for areas prone to moisture. However, it's important to ensure proper ventilation in the bathroom to prevent mold growth and prolong the lifespan of the drywall. For added protection, consider using a water-resistant paint or finish.
