How to Tile a Shower Floor Over Existing Tile

Tiling a shower floor over existing tile can be a great way to update your bathroom without a complete gut renovation. It's a relatively straightforward process that can be tackled by DIYers with some basic skills and patience. Here's a step-by-step guide on how to tile your shower floor over existing tile:

1. Preparation

  • Clear the area: Remove all fixtures, showerheads, and anything else that will be in the way.
  • Clean the existing tile: Use a strong cleaner to remove any soap scum, dirt, or mold.
  • Assess the existing tile: Check for loose or cracked tiles. If there are any, you'll need to remove and replace them.
  • Check for movement: If the existing tile feels unstable or moves underfoot, you may need to remove it and replace it with a new subfloor.
  • Remove grout: Use a grout saw or a grout removal tool to remove the existing grout.
  • Prime the surface: Apply a bonding primer to the existing tile to help the new tile adhere.

2. Laying the Tile

  • Measure and plan: Measure the area you will be tiling and plan the layout of your tiles. You can use a pencil and paper or a digital tiling software.
  • Set the first row: Use spacers to create even spacing between tiles.
  • Spread the mortar: Apply mortar to the floor, using a notched trowel to create even ridges.
  • Lay the tiles: Gently press the tiles into the mortar, ensuring that they are level.
  • Adjust and tap: Use a rubber mallet to tap the tiles into place and ensure they are flush.
  • Space and clean: Use spacers to maintain even spacing between tiles. Clean up any excess mortar.

3. Grouting

  • Wait for the mortar to dry: Allow the mortar to fully dry before grouting.
  • Mix the grout: Follow the manufacturer's instructions for mixing the grout.
  • Apply the grout: Use a grout float to apply the grout to the spaces between the tiles.
  • Clean up the excess: Use a damp sponge to wipe away excess grout.
  • Let it dry: Allow the grout to dry completely before cleaning.

4. Sealing and Finishing

  • Apply sealant: Use a sealant to protect the grout from stains and water damage.
  • Caulk the edges: Use silicone caulk to seal the edges of the tile where it meets the walls.
  • Reinstall fixtures: Install any removed fixtures, such as showerheads and drains.

Tips for Success

  • Choose the right tile: Consider the size, color, and material of the tiles to ensure they complement your bathroom decor.
  • Use a level: Ensure your tiles are level to avoid any unevenness.
  • Wear safety gear: Use safety goggles and gloves to protect yourself from dust and chemicals.

By following these steps, you can successfully tile your shower floor over existing tile and create a beautiful, functional space in your bathroom. Remember to carefully follow the instructions of your tile and grout manufacturer for optimal results.
