Installing a subway tile backsplash can transform the look of your kitchen or bathroom. With some planning and the right tools, even novice DIYers can achieve professional-looking results. Here is a step-by-step guide on how to lay a subway tile backsplash.
Introduction
A subway tile backsplash is a classic and timeless choice to protect your walls from water damage while adding style. The rectangular shape and stacked layout create a clean, streamlined look. Subway tiles come in glossy ceramic as well as natural stone, glass, and porcelain. Their small size makes them relatively easy for DIY installation.
Laying the tiles in a brickwork pattern offset from the center of the wall draws the eye up and creates visual interest. The grout lines also serve as decorative detail. Take care to properly prepare the surface and use spacers to keep the tiles evenly aligned. With some patience and the right techniques, you can achieve a showroom-worthy backsplash.

What You’ll Need
Before starting, ensure you have all the necessary materials and tools:
Materials
- Subway tiles
- Tile adhesive (thinset mortar)
- Grout
- Grout sealer
- Tile spacers
- Tile edging pieces like bullnose trim
Tools
- Mixing bucket, grout float, and grout sponge
- Notched trowel
- Tile wetsaw or nippers for cutting
- Rubber grout float
- Sponges
- Tile spacers
- Carpenter’s level
- Tape measure
Safety gear
- Safety glasses and gloves
- Knee pads
- Dust mask
Step 1: Prepare the Surface
Proper surface prep is crucial for the tiles to adhere correctly. The substrate must be clean, dry, and free of grease, paint, or sealants. Here are the basic steps:
- Remove existing backsplash if there is one
- Clean the surface thoroughly with a degreasing cleaner if needed
- Check for damage and fill any holes or cracks with spackling
- Sand down high spots and rough areas
- Wipe away dust with a clean, damp sponge
Ensure the surface is perfectly flat and plumb. Use a carpenter’s level tool to identify any problem spots.
Step 2: Plan Your Layout
A well-thought-out layout is key for a seamless look. Consider:
- Measure the space and calculate how many full tiles will fit
- Decide on the tile pattern – offset brickwork or a simpler straight layout
- Determine the best focal point – center on a window or symmetrical arrangement
- Choose the starting point based on the final look you want
- Draw a layout guide with pencil if needed
Having a planned layout will make the installation go smoothly.
Step 3: Apply the Tile Adhesive
To adhere the tiles properly:
- Read the thinset mortar instructions for prep
- Load the notched trowel evenly and apply adhesive to the surface
- Hold the trowel at a 45 degree angle to create ridges
- Only cover sections where tiles will be set right away
- Don’t let the thinset dry out before setting tiles
The notched trowel ensures the back of each tile is coated evenly for maximum adherence.
Step 4: Set the Tiles
Now comes the fun part of seeing your design take shape:
- Place spacers on each corner of the first tile
- Firmly press tiles into the adhesive using a slight twisting motion
- Use a grout float or beating block to apply even pressure
- Check for proper alignment as you go with a level
- Cut border and specialty tiles as needed with tile nippers or a wetsaw
- Let adhesive cure fully before grouting
Take care to keep tiles aligned and evenly spaced. Wipe away excess adhesive as you work.
Step 5: Apply the Grout
Grout fills the joints between tiles with color and texture. Follow these tips:
- Allow thinset to cure fully before grouting, usually 24-48 hours
- Apply grout float evenly over the surface, pressing into joints
- Hold the float at a 45-degree angle and remove excess grout
- Wipe diagonally across tiles to prevent dragging grout from the joints
- Clean tiles thoroughly to remove grout haze
- Allow grout to cure fully before sealing, about 72 hours
Choose a grout color that complements your tile. Contrasting or matching shades are both great options.
Step 6: Seal and Finish
The final sealing step protects the grout and completes your project:
- Read sealant instructions carefully before starting
- Test on a small area first to ensure it won’t stain the tiles
- Apply grout sealer evenly with a paintbrush or sponge
- Avoid puddling sealer on the surface
- Wipe away excess for a clean finish
- Allow sealer to cure fully before using the surface
Your stylish, how to lay a subway tile backsplash is now ready to enjoy! With proper prep and care, it will provide many years of beauty and protection.
FAQ

What kind of tile adhesive should I use?
For walls, a polymer-modified thinset mortar is best. It provides a strong bond and more flexibility. Make sure it is designed for your tile material.
Should the tiles go all the way to the ceiling?
Usually backsplashes end around 4 inches from the ceiling. But extending to the ceiling can look seamless and add height.
How much tile and supplies do I need?
Measure your space and add 10% extra to allow for cuts and mistakes. Estimate 1lb of grout per 10 sq.ft. and enough sealer to cover around 400 sq.ft.
Can I use subway tiles in my shower or tub surround?
Yes, subway tiles work well in wet areas due to their water resistance. Use a waterproofing membrane and epoxy grout.
What type of tile cutter should I use?
A wetsaw works best for straight cuts in subway tiles. Nippers are great for small notches like around outlets.
How long does the tile adhesive take to cure?
Thinset mortar usually cures in 24-48 hours. Don’t grout or walk on the tiles before the adhesive has cured fully.
