With the right research and understanding of the different types of backer board available, you can be sure to pick the best one for your specific shower needs.
In this blog post, we will discuss the various types of tile backer boards on the market, such as cement board, glass mat gypsum board, cement fiber, and foam shower tile backer board, so that you can make an informed decision.
Backer boards are essential for any tiling project, as they provide support and protection for your walls and floors.
A backer board for a shower is a specially designed board that provides a durable, water-resistant surface to attach tiles to in wet areas. Backer boards are commonly made of cement, fiber cement, or foam, and provide an extra layer of protection between the wall and the tile to ensure your shower lasts as long as possible.
They also help prevent water from seeping behind the tiles and into the walls, which can cause mold and damage to the structure of your home. Backer boards are essential for any tiled shower area and come in a variety of materials and thicknesses. Choosing the right backer board for your shower will ensure your tiles stay firmly attached and your shower remains watertight for years to come.

Cement board
Cement tile backer boards are the most common type of backer board used in shower applications. They are made with a mixture of Portland cement, sand, and a few other minerals to make a strong, durable, and water-resistant board.
Cement tile backer boards are extremely durable, so they’re perfect for wet areas like showers. They’re also fire resistant and impact resistant, making them ideal for a shower area. Cement tile backer boards can be found in various thicknesses, ranging from 1⁄2” to 1⁄4”. It’s important to note that cement tile backer boards should always be installed over a waterproof membrane for maximum protection.
Some common options for waterproofing material include liquid membrane, plastic ing, and uncoupling membrane. In plastic ing, 4 to 6 mil thick plastic goes over the wall studs that’s quite affordable and is popular as well. On the top, a waterproofing membrane is put over the tile backer board with mortar or mastic.
Glass Mat Gypsum Board
The board is composed of a gypsum core and fiberglass mat layers on both sides. The fiberglass provides superior strength and resistance to water, mildew, and mold. It is a more expensive option, but its durability makes it a wise investment.
The glass mat gypsum board is easy to cut and install. When properly installed and grouted, it provides a durable and waterproof surface that is resistant to mold, mildew, and rot.
For best results, seal the seams between boards with waterproofing tape or caulk. With proper installation, the glass mat gypsum board will last for years in your shower.
Foam Shower Tile Backer Board
The foam boards come in a variety of sizes, shapes and thicknesses, so you can easily find the right board for your shower. Additionally, they are easy to install and can be cut to fit your desired shape and size.
When installing the board, use water-resistant adhesive to make sure it adheres properly. Make sure to tape the seams and add an additional layer of waterproof membrane over the entire surface of the backer board. Doing this will ensure that moisture does not get inside the walls of your shower.
Overall, Foam Shower Tile Backer Board is an excellent choice for any shower tile installation. It’s lightweight and water-resistant, making it perfect for bathroom applications. Furthermore, its easy installation process makes it a great option for DIYers and professionals alike.
Cement fiber
The boards have a smooth surface that helps to prevent water infiltration and facilitate easier tile installation. The smooth surface also makes it easier to apply grout and other sealants, ensuring a watertight seal around your shower.
When it comes to installation, cement fiber boards can be cut with a saw or circular blade. However, you should use an appropriate respirator when cutting the boards to protect yourself from any potential dust particles. Cement fiber boards are also more expensive than some of the other options available, but the cost is well worth it due to their superior performance and durability.
Conclusion
Cement backer board is composed of a mixture of Portland cement, sand, and fiberglass mesh. It is lightweight, easy to work with, and provides excellent moisture resistance. Glass mat gypsum board is an ideal choice for use in showers and tub surrounds due to its durability and strength. Cement fiber board is made of wood fibers and Portland cement, making it very strong and stable. Finally, foam tile backer board is lightweight and easy to install, but it is not as durable as the other options.
When selecting a tile backer board, consider the environment where it will be installed. Different materials will fare better in different locations, so it’s important to make sure you choose the right one. Additionally, make sure that the board is installed correctly – it should be level and securely fastened to the subfloor. With proper installation, your tile backer board will help ensure your tiles remain in place for years to come.
