How to Do Glass Tile Backsplash

Installing a glass tile backsplash can be a great way to add a stylish, easy-to-clean accent to your kitchen or bathroom. Glass tiles come in a huge variety of colors, shapes, and sizes, allowing you endless design possibilities. With some planning and the right materials, installing a glass tile backsplash is a DIY project that most homeowners can tackle successfully.

Choose Your Glass Tiles

The first step is selecting the right glass tiles for your project. Consider the following:


Glass tile comes in every color of the rainbow, so pick a shade that complements your existing decor. Neutral colors like white, beige or gray create a clean, sleek look. Bold colors like red or turquoise make more of a statement.

Tile Shape

Common glass tile shapes include squares, rectangles, hexagons, diamonds, and subway tiles. Mixing up the shapes can create visual interest.

Tile Size

Smaller 1” mosaic tiles have a very different look than larger 4” tiles. Mixing tile sizes can have a nice effect.

Iridescent or Solid

Iridescent glass tiles have an irradiated coating that makes the surface shimmer. This effect is eye-catching, especially for backsplashes behind sinks.

Calculate How Much Tile is Needed

Once you’ve selected your tile, determine how much you’ll need to purchase. Measure the space and use an online calculator to estimate the square footage. Plan to buy 10-15% extra to account for tile cuts and breakage.

Gather Your Materials

In addition to the glass tile, you’ll need:

  • Tile adhesive
  • Grout
  • Grout sealer
  • Tile spacers
  • Tile cutter
  • Mixing buckets
  • Tile trowel
  • Grout float
  • Grout sponge
  • Utility knife
  • Safety gear like gloves and goggles

Make sure all materials are rated for use with glass tile, which is more fragile than ceramic or porcelain tile.

Prepare the Surface

The surface must be clean and smooth before tiling. Remove any old backsplash material or wallpaper. Fill any holes or imperfections with spackle. The area should be primed before you start setting tiles.

For a kitchen backsplash, remove any cabinets or countertops that butt up against the wall area to give yourself more working space.

Plan the Tile Layout

Map out your tile layout starting in the center and working outward. Use a level to draw even guideline rows. Mix up full and cut tiles along the edges and around outlets. Use tile spacers to maintain even grout lines.

Spread the Adhesive

Apply the adhesive evenly across the surface using a notched trowel. Only spread as much as you can tile over in about 20 minutes before the adhesive dries.

Set the Tiles

Place the tiles firmly into the adhesive, using spacers to maintain even grout lines. If the tiles slide downward over time, use painter’s tape to hold them in place until the adhesive sets.

Work in small sections and check periodically that the tiles are level. Allow the adhesive to fully cure before grouting.

Cut Any Custom Tiles

Use a wet saw or tile cutter to trim tiles to fit along the edges or around outlets and fixtures. Safety gear is a must when cutting tile. Make precise measurements and cuts to achieve a professional end result.

Apply and Clean the Grout

Follow package directions to mix up a batch of grout. Use a grout float to spread it across the surface, forcing it into the tile joints. Go slowly and keep grout off the tile surface.

After it dries, use a damp sponge to remove excess grout and smooth the lines. Rinse the sponge frequently. Allow to fully cure before sealing.

Seal the Grout

After full curing, apply grout sealer according to package directions to protect from moisture and stains. Avoid walking on the tiles for at least 24 hours.

Enjoy Your New Backsplash!

With proper prep and care, your glass tile backsplash will provide a beautiful, easy-to-maintain accent wall for years to come. The glass surface wipes clean easily. Use caulk along the edges if needed to prevent moisture seeping behind the tiles.

Glass tiles make a gorgeous addition to any home. With some planning and effort, you can DIY this project and save on installation costs. The finished look will add charm and elegance wherever it’s installed.
