The Ultimate Guide to Choosing and Installing Drywall in Your Bathroom


Welcome to our comprehensive guide on one of the most important, yet often overlooked aspects of bathroom renovations – the drywall.

A bathroom, apart from being a functional necessity, often serves as a personal sanctuary in your home. It’s a place of relaxation, reflection, and renewal. As such, every material used in its construction or renovation, right down to the drywall, should be chosen with care. Not only do they contribute to the aesthetic appeal of the space, but the durability and longevity of your bathroom also hinge on these choices.

Drywall, in particular, plays a pivotal role in your bathroom’s structure and overall longevity. Unlike other rooms in your house, your bathroom has to withstand a high level of humidity and moisture. Consequently, the type of drywall you install in your bathroom needs to be resistant to these conditions to prevent damage over time. This is not an area to cut corners, as the wrong choice could lead to costly repairs down the line.

In this guide, we will delve deep into the world of drywall for bathrooms. We’ll discuss why it’s such a popular choice, the different types suitable for your bathroom, the installation process, and how to maintain it to ensure your bathroom remains your personal oasis for years to come.

Whether you’re undertaking a complete bathroom renovation or just looking to upgrade certain elements, this guide will equip you with the knowledge you need to make informed decisions about your bathroom drywall. So, let’s dive in!

Why Drywall?

When it comes to bathroom renovations, homeowners often gravitate towards drywall, and for good reason. Drywall, also known as gypsum board, has been a staple in home construction for decades due to its versatility, cost-effectiveness, and relatively easy installation.

Drywall provides a smooth and uniform surface that’s perfect for painting or wallpapering, enabling you to achieve the aesthetic look you desire for your bathroom. Plus, it’s available in different thicknesses and sizes, allowing for flexibility in installation and design.

But perhaps the most compelling reason to choose drywall for your bathroom is its resistance to moisture. Bathrooms are naturally high-humidity areas in the home due to regular hot showers and baths. This moisture can penetrate walls and cause significant structural damage over time.

However, not all drywall is created equal when it comes to moisture resistance. Standard drywall, while excellent for other parts of the house, isn’t suitable for bathrooms due to its high susceptibility to water damage. That’s why manufacturers have developed special types of drywall, like green board and cement board, specifically designed for high-moisture environments like bathrooms. These types of drywall have a moisture-resistant core and are covered with a water-resistant paper or fiberglass mat, reducing the risk of water damage.

In the following sections, we will delve deeper into the different types of drywall for bathrooms, their specific properties, and how to choose the one that’s right for your project. Whether you’re creating a luxurious spa-like retreat or a simple, functional space, the right type of drywall can help you achieve your vision while ensuring your bathroom stands the test of time.

Types of Drywall for Bathrooms

Navigating the world of drywall can be somewhat overwhelming, especially when it comes to choosing the right one for your bathroom. However, understanding the different types and their unique properties can greatly assist you in making an informed decision. Here, we’ll discuss some of the most popular types of drywall used in bathrooms: greenboard, cement board, and purple board.


Greenboard, aptly named for its green paper covering, is a type of drywall that’s designed to be more resistant to moisture than regular drywall. It’s an excellent choice for areas of your bathroom that are exposed to humidity but not directly to water, like the main walls.

Pros: Greenboard is relatively easy to install and cut, making it a popular choice for DIYers. It’s also less expensive than other moisture-resistant drywall types.

Cons: While greenboard is moisture-resistant, it’s not waterproof. Therefore, it’s not the best choice for areas that come into direct contact with water, such as shower or bathtub walls.

Cement Board

Cement board, also known as backer board or cementitious board, is a rigid panel made of cement and reinforcing fibers. It’s a fantastic choice for areas that are frequently exposed to water, such as shower enclosures, bathtub surrounds, or behind bathroom sinks.

Pros: Cement board is extremely resistant to water and mold growth. It provides a solid, durable surface for tile installation.

Cons: Cement board is more difficult to cut and install than other types of drywall, making it a less popular choice for DIYers. It’s also more expensive than greenboard.

Purple Board

Purple board is a newer addition to the drywall scene. It’s similar to standard drywall, but it has been treated with a special water and mold-resistant material. The name comes from the unique purple paper facing used on the board.

Pros: Purple board is highly resistant to moisture and mold, making it an excellent choice for bathroom installations. It also provides the same ease of installation as standard drywall, making it popular for DIYers.

Cons: Purple board is more expensive than greenboard and standard drywall. While it’s resistant to moisture and mold, it’s not as robust in direct water exposure situations as cement board.

In summary, the best type of drywall for your bathroom depends on the specific requirements of your project. Assess the moisture exposure levels in different areas of your bathroom to determine the most suitable type of drywall for each. This will ensure your bathroom remains durable and free from water damage for years to come.

Installation Process

Installing drywall in your bathroom might seem like a daunting task, but with the right tools, some patience, and this step-by-step guide, you can make the process smoother and ensure a quality result. Here’s how to do it:

Step 1: Measure and Cut the Drywall Start by measuring the wall where you’ll be installing the drywall. Once you have the measurements, transfer them to the drywall sheet and use a utility knife to score the front side. Snap the board along the scored line, and then cut the back paper.

Step 2: Install the Drywall Position the cut drywall piece on the wall. Using a drill, secure the drywall to the wall studs with drywall screws. Ensure the screws are flush with the drywall but not breaking through the paper.

Step 3: Cut Out Openings If the piece of drywall you installed has any openings for outlets or fixtures, you’ll need to cut these out. Use a keyhole saw or a rotary tool for this. Make sure to do this after the drywall is secured to avoid any misalignment of the openings.

Step 4: Repeat the Process Continue the process of measuring, cutting, installing, and cutting out openings until all walls are covered with drywall.

Step 5: Apply Joint Compound Once all drywall is installed, apply joint compound (also known as ‘mud’) to all seams and screw holes. Place a strip of drywall tape over the seams and cover with another layer of joint compound. Allow it to dry as per the manufacturer’s instructions.

Step 6: Sand and Paint Once the joint compound is dry, sand the area to create a smooth surface. Wipe off any dust before applying a primer and the paint of your choice.

Here are a few tips to ensure a smooth installation process:

  • Plan Ahead: Sketch out your bathroom and plan where each piece of drywall will go. Try to arrange it so the number of seams is minimized, as these are the hardest to disguise.
  • Safety First: Always wear safety glasses and a dust mask when cutting and installing drywall.
  • Proper Tools: Having the right tools can make the job much easier. This includes a utility knife, a drywall saw, a drill, a mud pan, a taping knife, and a sanding pole.
  • Mold Resistant Materials: For the bathroom, consider using mold-resistant joint compound and tape to further protect your walls from moisture damage.

Remember, if at any point you feel overwhelmed or unsure about the process, it’s best to call in a professional. Proper installation is crucial to the longevity and durability of your drywall.

Maintaining Your Bathroom Drywall

Now that your bathroom drywall is installed, it’s crucial to understand how to maintain it. Proper maintenance will not only ensure your bathroom continues to look its best, but it can also help prolong the lifespan of your drywall. Here are some tips for maintaining your bathroom drywall:

Ventilation is Key

One of the best ways to prevent moisture damage to your drywall is to ensure your bathroom is properly ventilated. Use exhaust fans during and after showers to reduce the amount of moisture in the room. Keeping windows open when possible can also help improve ventilation.

Regular Cleaning

Regular cleaning is essential to keep your drywall in good shape. Wipe down painted drywall with a damp cloth and mild soap. Avoid using harsh chemicals, as they can damage the paint and drywall surface.

Check for Signs of Mold and Mildew

Given the high-moisture environment of a bathroom, it’s important to regularly check for signs of mold and mildew on your drywall. If caught early, it can be cleaned with a mildew cleaner or a solution of one part bleach to four parts water. Always use gloves and ensure the room is well-ventilated when using these solutions.

Repairing Minor Damages

For minor dents or holes, you can use a joint compound or a drywall repair kit to fix the damage. Apply the compound to the damaged area, smooth it out with a putty knife, and let it dry. Once dry, sand it smooth and apply paint to match the rest of the wall.

Professional Inspection

If you notice larger issues like sagging drywall, significant mold growth, or water damage, it’s best to call in a professional. These issues could indicate a larger problem that needs to be addressed.

Properly maintaining your bathroom drywall can help prevent costly repairs down the line and keep your bathroom looking its best. In the next section, we’ll discuss when it’s best to call in a professional to handle your bathroom drywall needs.

When to Call a Professional

While DIY projects can be rewarding and cost-effective, there are situations where it’s better to call in a professional. Drywall installation and repair can be complex, especially in moisture-rich environments like bathrooms. Here are some scenarios where you might want to consider hiring a professional:

1. Large-Scale Projects

If you’re undertaking a large-scale renovation, such as a complete bathroom overhaul, it might be wise to hire a professional. They have the experience to handle large projects efficiently and can tackle any unexpected issues that might arise.

2. Complex Installations

If your bathroom has a lot of corners, niches, or unusual angles, installing drywall can become quite complex. A professional can ensure the drywall is cut and installed correctly, providing a smooth and seamless finish.

3. Significant Damage or Mold Growth

If you discover extensive water damage or mold growth on your drywall, it’s time to call in a professional. These issues could indicate a serious underlying problem that needs to be addressed. Professionals can assess the situation, determine the cause, and provide the necessary repairs.

4. If You’re Unsure

If you’re uncertain about any aspect of the installation or repair process, don’t hesitate to call a professional. It’s better to get it done right the first time than to risk potential damage or additional costs down the line.

When choosing a professional for your bathroom drywall project, consider the following:

  • Experience: Look for professionals who have experience with bathroom drywall installation and repair.
  • Reviews and Recommendations: Check online reviews or ask for recommendations from friends or family.
  • Estimates: Get estimates from several contractors to ensure you’re getting a fair price. Make sure the estimate includes materials, labor, and any other potential costs.
  • License and Insurance: Always hire a licensed and insured contractor to protect yourself in case of any accidents or damages.

Remember, while DIY can be a great option for many home projects, knowing when to call in a professional is key to maintaining the integrity and longevity of your bathroom drywall.
