What Color Grout For Glass Tile Backsplash

Choosing the right grout color for a glass tile backsplash can make a huge difference in the overall look and feel of your kitchen. The grout lines act as accents against the glass tiles, so selecting a shade that complements the tiles is key. Here are some tips on picking the best grout color for glass tile backsplashes.

Factors to Consider When Choosing Grout Color

When selecting a grout color for glass tile, keep the following factors in mind:

Glass Tile Color

Match the grout color to the predominant color in the glass tile. For example, use a white grout with clear, frosted, or pale-colored glass tiles. Choose a gray grout for a backsplash with gray glass tiles. Go for black grout with darker colored glass tiles. Selecting a grout color that matches or blends with the tile color makes the grout lines less obvious.

Personal Preference

Consider the look you want to achieve. Do you want the grout lines to stand out and be noticeable or blend in subtly with the tile color? Dark grout provides contrast and makes the grid pattern obvious, while matching grout hides the lines. Determine whether you want the grout to be a focal point or fade into the background.

Kitchen Aesthetic

The existing kitchen decor and color scheme should factor into your grout decision. For a bright, airy look, use white or light grout. In contemporary spaces, gray is a popular choice. Black grout has a bold, dramatic effect. Make sure the grout complements your kitchen’s overall style.


The amount of natural and artificial lighting can affect grout appearance. White grout shows stain easily in high-traffic areas lit with brighter lights. Dark grout hides grime better in such conditions. Consider the lighting and exposure levels where the backsplash will be installed.

Popular Grout Color Options for Glass Tiles

Here are some of the most popular grout shade choices for glass tile backsplashes:


White grout is a clean, classic choice that works well with any color of glass tile, from clear to bright hues. It has a light, airy effect but will need frequent cleaning. White is ideal for backsplashes in cottage, farmhouse, or vintage decors.


From light pewter to dark charcoal, gray grout is versatile and pairs nicely with both light and bold colored glass tiles. It has a modern, sleek look. Gray also disguises dirt better than white. Use a gray tone that matches or contrasts with the tile.


For dramatic visual impact, black grout can provide striking contrast against glass tiles in shades of blue, green, clear, or frosted white. Keep in mind that black shows flaws more readily than lighter colors. Use black grout in contemporary, modern, or retro kitchen designs.


For a soft, earthy feel, beige or tan grout works well with glass tiles in peach, amber, brown, taupe, or other neutral shades. Beige has a more subtle effect than white or gray. Keep beige grout looking clean by sealing it regularly. Use it in Tuscan, Mediterranean, or rustic decor.

Grout Color Considerations for Specific Glass Tile Types

The exact color and finish of the glass tiles should guide your grout choice. Here are recommended grout colors for popular glass tile varieties:

Clear Glass Tile

Pair clear glass tile with white or gray grout. White provides definition, while gray adds subtle contrast. Stay away from darker grouts, which can look dirty against the transparent tile.

Frosted or Etched Glass Tile

Use white or beige grout with frosted glass for a soft, harmonious look. Gray is another option that allows the texture to stand out. Avoid black with frosted glass.

Metallic Glass Tile

With iridescent glass tiles, select white or gray grout. The shimmering tiles pop against a neutral background. Stay away from beige or black grout with metallic glass.

Patterned Glass Tile

If the glass tile has a bold pattern, use white or gray grout to let the design take center stage. For a coordinating look, choose a grout color that matches the predominant glass color.

Colored Glass Tile

Match the grout to the main glass tile color for a cohesive effect. Using a contrasting grout color can create extra drama and dimension. Just ensure the two hues complement each other.

Grout Color Recommendations by Kitchen Style

Certain grout shades pair better with specific kitchen aesthetics. Some suggested combinations:

Traditional Kitchen – Use white grout with any glass tile type for a classic backsplash.

Country Kitchen – Stick with beige, tan, or white grout depending on the glass tile hue.

Contemporary Kitchen – Gray, white, or black grout will provide the right modern edge.

Rustic Kitchen – Beige or gray grout enhances the natural charm of a rustic decor.

Eco-Friendly Kitchen – White or light gray grout complements the clean lines of a sustainable space.

Retro Kitchen – For vintage appeal, use white or black grout with vividly colored glass tile.

Urban Kitchen – Charcoal or dark gray grout adds an edgy, chic vibe against glass mosaic tiles.

Grout Color Pairings to Avoid

Some grout and glass tile combinations should be avoided, as they can look dirty, dated, or create visual confusion:

  • Black grout with clear, frosted, metallic, or other light-colored glass tile
  • Beige grout with bold-hued glass tile like cobalt blue or emerald green
  • White grout with patterned or heavily textured glass tile – the grout competes visually
  • Gray grout with glass tile that has gray tones – this can look monotonous
  • Clashing colors like red with green glass or pink with purple

Grout Color Tips and Tricks

Follow these additional tips for choosing and using grout with a glass tile backsplash:

  • View color samples in person before deciding on a shade. Colors look different on a monitor than in real life.
  • Use sanded grout for joints wider than 1/8″, unsanded for narrower spaces. Sanded grout resists staining better.
  • Consider ease of maintenance. Dark grout hides dirt but requires sealing. White shows everything but cleans up well.
  • Contrasting grout makes the grid pattern obvious. Matching grout minimizes the lines. Choose the visual effect you prefer.
  • Grout can be tinted during installation. Tinting to match the tile minimizes visible grid lines.
  • If using mosaic sheets, choose grout that matches the mesh backing for a seamless look.
  • Make sure the grout complements the overall kitchen color scheme.
  • Allow 2-3 days for grout to fully cure before cleaning and sealing the lines.
