3" x 12" Glass Subway Tiles for Kitchen Backsplashes and Shower Walls

The elongated proportion of 3" x 12" glass subway tiles delivers a contemporary update to the classic subway look.

Glass reflects light, brightens spaces, and is naturally non-porous—making it a practical, attractive choice for wet or high-use areas.

  • Color range: Available in classic white, vibrant blue and green tones, and subtle neutrals to match any palette.

Design Ideas & Applications

  • Shower walls: Install shower wall glass subway tiles in horizontal runs for a classic effect or vertically for added height and drama.
  • Pattern play: Try stacked, vertical, or herringbone patterns to introduce movement and texture.
  • Accent combinations: Pair with mosaics, natural stone, or metal trim to create contrast and detail.

FAQ's on 3" x 12" Glass Subway Tiles from BELK Tile

3” x 12” glass subway tile is a modern twist on the classic subway tile format. The larger size creates fewer grout lines for a cleaner, more contemporary look while still offering the reflective depth and vibrant color that glass tile is known for.

Yes. The elongated size can make a kitchen look more spacious and streamlined, while the glass surface is waterproof, stain-resistant, and easy to clean. It also reflects light, helping to brighten dark kitchens.

Absolutely. 3” x 12” glass subway tiles are perfect for shower walls because they are non-porous, mold-resistant, and easy to maintain. The larger format can also make the space look taller or wider, depending on the installation pattern.

They are a bit more challenging to install than ceramic tiles because glass is translucent and prone to chipping if cut incorrectly. White thin-set mortar should be used to prevent visible shadows. A smooth, even substrate is essential for a flawless finish.

They are typically more expensive than ceramic subway tiles, but the cost is offset by their high-end, elegant look and ability to enhance light in a room. The larger size may also reduce installation labor time compared to smaller tile formats.
