Which type of drywall is specifically used in bathrooms?

Regular board
Green board
Blue board
Fire-resistant board

The correct answer is: Green board

Green board is specifically designed for use in areas with high moisture, such as bathrooms. This type of drywall features a moisture-resistant core and a special green paper facing, which helps prevent mold and mildew growth. It is not waterproof but is more resistant to moisture compared to standard drywall, making it a common choice for bathroom applications, where humidity levels can fluctuate significantly due to showers and baths. Regular board lacks moisture resistance and is not suitable for wet environments, while blue board is primarily used for veneer plaster applications and may not provide the necessary moisture protection for bathrooms. Fire-resistant board is intended for use in areas where additional fire resistance is required, such as garages or near furnaces, but does not address moisture issues relevant to bathrooms. Thus, the properties of green board make it the ideal selection for drywall installations in bathrooms.
