Can You Tile Over Tile Shower Floor?

Yes, you can tile over tile in your shower floor, but it's not always the simplest or most straightforward project. Here's a breakdown of what to consider:

Factors to Consider Before Tiling Over Tile:

  • Existing Tile Condition: The most important factor is the condition of the existing tile. If the tiles are cracked, loose, or have grout that's crumbling, you'll need to remove them before tiling over.
  • Existing Tile Thickness: If the existing tile is very thick, it can create a thicker base for the new tile, making the shower floor uneven. Consider removing the existing tile if it's too thick.
  • Existing Mortar Adhesion: The existing mortar beneath the tiles needs to be strong and properly adhered to the subfloor. If the mortar is weak or failing, you'll need to remove the tile and re-install it with fresh mortar.
  • Shower Floor Slope: Ensure the existing shower floor has the correct slope for drainage. A poorly sloped floor can lead to water pooling and damage.

Pros of Tiling Over Tile:

  • Cost-Effective: Tiling over existing tile can be more affordable than removing and replacing the entire floor.
  • Less Messy: Removing and replacing tile can be a messy and time-consuming process. Tiling over tile can reduce this mess.
  • Faster Project: Tiling over existing tile can be completed faster than removing and replacing the entire floor.

Cons of Tiling Over Tile:

  • Uneven Surface: If the existing tile is uneven, the new tile may not be as smooth or flat.
  • Increased Height: Tiling over tile can raise the height of the shower floor. This could be a problem if the shower door is close to the floor.
  • Potential for Failure: If the existing tile is not properly secured or the mortar is weak, the new tile could fail.

Tips for Tiling Over Tile:

  • Clean and Prepare the Surface: Thoroughly clean the existing tile with a degreaser to remove any dirt, soap scum, or mold.
  • Use a High-Quality Bonding Agent: Apply a bonding agent to the existing tile to create a strong bond between the new tile and the old tile.
  • Apply Thin-Set Mortar: Use a thin-set mortar designed for tiling over tile.
  • Ensure Adequate Drainage: Verify the shower floor has the proper slope for drainage after tiling.

Conclusion:

Tiling over tile in your shower floor is possible, but it's important to carefully consider the factors involved and proceed with caution. If you're unsure, it's always best to consult with a professional tile installer.
