If you’re planning a bathroom renovation and wondering about your options regarding your backer boards, this blog is for you. When tiling your bathroom, one of the most important factors is what type of board to use. There are four main types: cement board, fibreglass cement board, glass mat tile backer board and foam backer board. Each has its advantages and disadvantages. Here’s a look at each one:
A cement board is a mix of cement and reinforcing wood flakes moulded into sheets for tiling purposes. Generally, you will use a sheet of cement board for tiling walls around your bathtub, shower, or sink. These boards are available in different thicknesses. The average thickness of 1/4 inch is good for floor installations and will weigh thirty to forty pounds. For walls, use a thicker board, at least 3/8 inch, which will weigh forty to fifty pounds.
Cement boards are waterproof and rot-proof, making them ideal for wet areas. They won’t swell or soften when exposed to water. Cement boards also provide a flat, stable surface for tile installation in bathrooms.
One downside of cement board is that it’s heavy. This can make installation difficult, especially if you’re working alone.
Cut the cement board to size with a utility knife and T-square. Be sure to score the board deeply. Use the square to ensure a straight line, snapping the waste area back in place. Cut the board to size using fibreglass mesh to make it even with the surrounding walls. This is the easiest way to install tile boards in your bathroom, shower, or kitchen. Make sure to use the correct size screws to make the process easier.
Fibre cement board
A Fibre cement board is a tile backer board made with Portland cement, silica, and cellulose fibres. It’s denser than regular cement board, making it ideal for floors and countertops. Fibre cement boards are also waterproof and rot-proof.
Fibre cement boards come in different thicknesses, but the average is 1/2 inch. These boards are also available in different sizes, making them easier to work with. Fibre cement boards are more expensive than regular ones, but they’re still a good choice for wet areas.

Glass mat tile backer board
Durock™ makes a revolutionary product named Glass-Mat Tile Backerboard. This product’s gypsum core is covered with a coated fibreglass mat facer and back. The matting is embedded with alkali-resistant glass fibres for exceptional strength and stability.
This type of tile backer board is waterproof, making it ideal for wet areas like showers and tub surrounds. Glass-mat tile backer board is also moulded and mildew resistant. It won’t swell or soften when exposed to water.
Glass-mat tile backer board is easy to install. It’s available in different thicknesses and sizes, making it easy to find the right one for your project. Glass-mat tile backer board is more expensive than a regular cement board, but it’s worth the investment.
Foam backer board
A foam backer board is a tile backer board made of foam. It’s available in different thicknesses and sizes, making it easy to find the right one for your project. Foam backer board is easy to install and is less expensive than other types of tile backer boards. The advantage of a foam backer board is the fact that it is light in weight.
This can make installation easy, especially if you’re working alone.
The disadvantage of a foam backer board is that it’s not as strong as a cement board. It also doesn’t provide the same level of support. Foam backer boards are not recommended for floors or countertops.
Plywood should not be used for shower walls.
Plywood is a good choice for subfloor but not for shower walls. It can be installed directly on your floor joists, but there are some limitations. First, plywood is not ideal for wall installations. In most cases, plywood will be sufficient as a subfloor. However, if you plan to install tile directly on plywood, you must use the recommended thin-set for installation. You should make sure that the subfloor is stable, ventilated and level. You may need to increase the thickness of the plywood if the tiles are heavy or the joist spacing is wide. Make sure you prime the plywood, cut the sheets to the desired length and width and attach them to every 200-300mm spacing with screws. Remember to leave a gap of two to three mm for expansion.
