What Drywall to Use in Bathrooms

Drywall is a versatile and affordable material suitable for various applications, including bathrooms. However, not all types of drywall are created equal, and choosing the right one for your bathroom is crucial to ensure durability and prevent moisture damage.

Bathrooms are known for their humid environments, making them prone to moisture absorption. Using regular drywall in such areas can lead to mold growth, structural damage, and unsanitary conditions. To avoid these issues, it's essential to use drywall specifically designed for moisture-prone areas like bathrooms.

Green Drywall (Moisture-Resistant)

Green drywall, also known as moisture-resistant or MR drywall, is an excellent option for bathrooms. It features a green-colored paper facing that resists moisture absorption better than regular drywall. The gypsum core of green drywall is also treated with water-repellent additives, making it more resistant to mold and mildew growth.

Green drywall is recommended for areas with moderate to high moisture exposure, such as bathrooms with showers, bathtubs, and steam generators. It can be used on walls and ceilings, providing added protection against moisture-related problems.

Purple Drywall (Mold-Resistant)

Purple drywall, also known as mold-resistant or MR+ drywall, takes moisture resistance a step further by incorporating mold-inhibiting agents into its composition. These agents help prevent mold spores from developing on the drywall surface, offering enhanced protection against mold growth.

Purple drywall is ideal for bathrooms with extreme moisture exposure, such as those with poor ventilation or frequent water leaks. It is highly effective in preventing mold growth, ensuring a healthier and more sanitary bathroom environment.

Blue Drywall (Fire-Resistant)

Blue drywall, also known as fire-resistant drywall or Type X drywall, offers exceptional fire resistance compared to regular or moisture-resistant drywall. It is designed to withstand higher temperatures for an extended period, delaying the spread of fire.

While blue drywall is not specifically moisture-resistant, it can be used in bathrooms in combination with moisture-resistant paint or a waterproof membrane to provide a moisture-resistant barrier. This combination can offer a comprehensive solution for bathrooms requiring both fire and moisture protection.

Tips for Installing Drywall in Bathrooms

In addition to selecting the appropriate drywall, the proper installation techniques are crucial for ensuring its durability and performance in bathrooms:

Use mold-resistant drywall joint compound and tape to seal joints and seams.
Install a moisture-resistant primer on the drywall before applying paint.
Consider installing a waterproof membrane behind the drywall to prevent water intrusion.
Provide adequate ventilation in the bathroom to reduce humidity and prevent moisture buildup.

By following these guidelines, you can ensure that your bathroom drywall will withstand moisture and remain in good condition for years to come.
