Bathroom drywall should resist moisture and mold. Options range from standard whiteboard (for dry areas) to moisture-resistant green and purple boards, which are recommended for bathrooms.
1. White Board (Standard Drywall)
The most common drywall, sold in 4×8 ft sheets. Suitable for dry areas like living rooms and bedrooms, not recommended for bathrooms.
2. Greenboard (Moisture-Resistant)
Designed for high-humidity areas, such as bathroom walls. It resists moisture but is not waterproof, so avoid using it in showers.
3. Blue Board (For Veneer Plaster)
Moisture-resistant plasterboard used as a base for plaster finishes. Works well in bathrooms and under tile, but not for direct water contact.
4. Purple Board (Moisture, Mold, and Mildew Resistant)
Highly resistant to moisture, mold, and mildew. Ideal for bathroom walls and ceilings in high-humidity spaces.
5. Paperless Drywall
Made with fiberglass facing instead of paper. Moisture-resistant and durable, but not suitable for areas exposed to direct water (such as shower walls).
6. Type X Drywall (Fire-Resistant)
Fire-rated drywall used where fire protection is required. Can be used in bathrooms, but should be paired with moisture-resistant options in wet areas.
Maintenance Tips
To keep your bathroom drywall in good condition and prevent mold buildup, follow these simple steps:
- Always use a vent fan to reduce humidity after showers and baths.
- Check for leaks regularly around plumbing fixtures and ceilings.
- Use high-quality bathroom paint designed for moisture resistance to protect the drywall surface.
