When renovating or building a bathroom, selecting the right drywall is crucial to ensuring durability and moisture resistance. Bathrooms are exposed to high humidity, water splashes, and steam, which can cause damage to standard drywall. Choosing the right type of drywall can prevent issues like mold, mildew, and structural deterioration. Here are the common types of drywalls used in bathrooms:
- Blueboard
- Cement Board
- Enviro-Board Drywall
- Greenboard
- Paperless Sheetrock Drywall
- Purple Drywall
- Soundboard Drywall
- Soundproof Drywall
- Type X & Type C Boards
1. Blueboard
Blueboard is a plaster-based drywall designed to withstand moderate moisture levels. It’s ideal as a base for veneer plaster, offering a smooth surface and good moisture resistance. Blueboard isn’t entirely water-resistant but works well in areas with less direct exposure to moisture, making it a good option for bathrooms with controlled humidity.
2. Cement Board
Cement board is a highly durable alternative to traditional drywall, known for its water-resistant properties. It’s often used in wet areas like showers or tub surrounds where drywall’s water tolerance would otherwise fail. Cement board prevents water damage and provides a sturdy surface for tiles or other wall finishes. Its ability to withstand high moisture levels makes it the go-to choice for bathrooms exposed to regular water exposure.
3. Enviro-Board Drywall
Enviro-Board drywall is an eco-friendly option made from recycled materials. It offers moderate moisture resistance, making it suitable for bathroom environments that are subject to humidity but not direct water contact. While not as durable as cement board, it’s a more sustainable choice for those looking to minimize their environmental impact.
4. Greenboard
Greenboard is a type of moisture-resistant drywall that features a water-repellent paper surface. It’s commonly used in bathrooms, especially in areas with high humidity like near sinks or bathtubs. Though greenboard can handle some moisture, it’s not as durable as cement board in very wet conditions, but it still offers a good level of protection against everyday bathroom humidity.
5. Paperless Sheetrock Drywall
Paperless Sheetrock drywall features a fiberglass coating rather than paper, making it resistant to mold and mildew. This makes it an excellent option for bathrooms, where moisture is a constant concern. Paperless drywall provides a moisture-resistant barrier that helps prevent mold growth, making it a great alternative to traditional paper-backed drywall.
6. Purple Drywall
Purple drywall is designed specifically for maximum resistance to moisture and mold, making it an ideal option for high-humidity environments like bathrooms. It offers superior protection against water damage and is particularly beneficial in spaces where mold could be an issue. Purple drywall’s enhanced moisture resistance helps maintain the integrity of bathroom walls over time.
7. Soundboard Drywall
Soundboard drywall is designed to reduce noise transmission between rooms. While it’s not moisture-resistant, it can still be used in a bathroom if combined with a moisture barrier. This drywall helps create a quieter environment by preventing noise from traveling between the bathroom and adjacent rooms, making it an excellent choice for shared bathrooms or small homes.
8. Soundproof Drywall
Soundproof drywall, or acoustic drywall, minimizes sound transfer and can be used in bathrooms where noise reduction is a priority. Though it’s moisture-controlled, it is not specifically designed to withstand high humidity. When used in bathrooms, it’s best to combine it with other moisture-resistant materials to ensure long-term performance.
9. Type X & Type C Boards
Type X and Type C boards are fire-resistant drywall options that provide an extra layer of safety, especially in bathrooms near heat sources like vents or heaters. These boards can also come in moisture-resistant versions, offering dual protection against both fire and water damage. Type X and C boards add an important layer of safety in areas where high temperatures and moisture are concerns.
Factors to Consider When Choosing Drywall for Bathrooms
Moisture Resistance
Moisture-resistant drywall is essential in bathrooms, as it helps prevent water damage, swelling, and structural issues caused by high humidity or direct water exposure. Choosing drywall with a higher resistance to moisture can greatly extend the lifespan of your bathroom walls.
Mold Protection
Mold-resistant drywall inhibits the growth of mold and mildew, which are common problems in damp bathroom environments. Choosing drywall that offers mold protection can improve the air quality in your bathroom and prevent the development of health hazards.
Durability
Durability is key when choosing drywall for a bathroom. You need a material that can withstand everyday wear and tear while maintaining its appearance and structure. Consider options like cement board or purple drywall for long-lasting results.
Fire Resistance
Fire-resistant drywall, such as Type X or Type C boards, provides added safety in bathrooms, particularly near heat sources like ventilation ducts or space heaters. This type of drywall adds an extra level of protection against fire hazards.
Soundproofing Capabilities
If you’re looking to reduce noise in your bathroom, soundproof drywall options like soundboard and soundproof drywall can help minimize sound transfer between rooms. This is particularly useful for shared or small bathrooms.
How to Take Care of Your Bathroom Drywall?
To prolong the life of your bathroom drywall, regularly check for signs of moisture damage or mold growth, especially in high-humidity areas. Clean surfaces gently and avoid harsh chemicals that can deteriorate the surface. Proper ventilation is also essential in preventing moisture buildup that could damage your drywall. Installing a dehumidifier and using exhaust fans can help keep humidity levels in check, ensuring that your drywall stays intact and free of mold or mildew.
