Tools and Materials Needed
Installing subway tile is a straightforward DIY project. With some simple tools and materials, you can achieve a high-end backsplash look. Here is what you need to get started:
Tools
- Tape measure
- Pencil
- Level
- Tile cutter

Make sure to purchase about 10-15% extra tile to account for broken tiles and custom cuts. The quantity needed will depend on the dimensions of your backsplash.
Preparing the Surface
Proper surface preparation is crucial for a successful subway tile installation. Follow these steps to prepare the area:
- Clean the surface thoroughly – Eliminate all grease, soap residue, and dust. For existing backsplashes, remove the old tiles, adhesive, and grout completely.
- Make any needed repairs – Address any water damage, rough spots, or holes in the wall. Subway tile should be installed on an even surface.
- Install backerboard if needed – Cement board or a water-resistant backerboard should be installed unless you already have suitable substrates like cement, plywood, or drywall.
- Mark the tile layout – Map out the tile layout using a pencil and level. Mark guidelines for the first row of tiles.
Once the surface is prepared, you’re ready to begin tiling!
How to Install Subway Tile Backsplash
Follow these steps for a foolproof subway tile installation:
Step 1: Apply Mortar or Adhesive
- Spread a layer of thinset mortar or adhesive on the installation area using a notched trowel. Apply only a workable area so the mortar does not dry before tiles are set.
Step 2: Set the First Row
- Starting at the base, press tiles into the mortar and align with your layout lines. Use spacers between tiles for even grout lines.
- Check tiles are level and pressed firmly into the mortar. Adjust as needed.
Step 3: Install the Remaining Tile
- Continue setting tiles row by row, working upwards. Use tile spacers to maintain even grout lines.
- Cut subway tiles as needed to fit around outlets, corners, or edges using a tile cutter.
- Let the mortar fully cure for 24-48 hours before grouting.
Step 4: Grout the Tiles
- Apply grout along the grout lines using a rubber grout float or squeegee, pressing firmly to fill any gaps.
- Wipe away excess grout with a damp sponge. Rinse sponge frequently.
- Allow grout to dry fully then polish the tiles to a shine with a soft cloth.
Step 5: Seal and Finish
- Once grout has cured, apply a penetrating grout sealer to protect from moisture and stains.
- Lastly, caulk between the countertop and tiles, along the edges, around fixtures, or at any change of plane.
And that’s it – you now have a stunning and durable subway tile backsplash! Proper prep and taking your time with each step will ensure your installation looks polished and professional.

Follow these pro tips for a flawless finished look:
