Do I Need Cement Board Under Bathroom Tile Floors?

Installing tile floors in your bathroom is a great way to add style and value to your home. However, before you start laying tile, it is important to make sure that you have the right materials in place and that it is properly supported with a firm and stable base. Using cement board for your tile floor backing is a good option since it is a sturdy material that can make your tile floor last for years to come.

Cement board is made from a mixture of cement, sand, and fibers. It is a strong and rigid material that is resistant to moisture and rot. This makes it an ideal choice for use in areas that are exposed to water, such as bathrooms. Cement board is also easy to cut and install, making it a good option for DIYers.

There are a few reasons why you might need cement board under bathroom tile floors:

To provide a smooth and level surface for the tile.
To prevent moisture from damaging the subfloor.
To add strength and stability to the tile floor.
To reduce the risk of cracking or chipping tiles.

If you are considering installing tile floors in your bathroom, it is important to talk to a professional to see if cement board is the right choice for you. Cement board is not necessary in all cases, but it is a good option for bathrooms that are exposed to a lot of water or that have a weak subfloor. Waterproof backer boards, also known as Wedi Board or Schluter Kerdi Board, are popular alternatives to cement board and offer similar benefits.

If you do decide to use cement board, it is important to install it correctly. Cement board should be installed over a level subfloor that is free of any debris.

Here are the steps on how to install cement board:

Measure the subfloor and cut the cement board to size.
Apply a thin layer of thinset mortar to the subfloor.
Set the cement board on the subfloor and screw it into place.
Tape the seams between the cement board with fiberglass mesh tape.
Apply a second layer of thinset mortar to the cement board.
Let the thinset mortar dry completely before installing the tile.

Installing cement board under bathroom tile floors is a relatively simple process, but it is important to take your time and do it correctly. By following these steps, you can ensure that your tile floor will be beautiful and durable for years to come.
