Buying Guide: Key Considerations For Gray Glass Subway Tiles
- Color and tone: Gray glass tiles range from cool storm greys to warmer greys. Consider lighting in the space—cool lighting reads blue-toned, warm lighting reads taupe or beige undertones.
- Tile size and layout: 3 x 6 is classic and easy to stagger for a traditional subway vibe. 3 x 12 (peel-and-stick) offers faster installation and different visual rhythm.
- Glass thickness and edge: Thicker glass and beveled or straight edges affect durability and grout lines. 8 mm and similar thicknesses typically balance stiffness with ease of cutting.
- Installation method: Standard tiles require thin-set and grout; peel-and-stick options remove mortar but may have limitations on heavy-use surfaces or moisture exposure.
- Maintenance: Glass tiles are non-porous and easy to wipe, but grout color choices influence long-term cleanliness. Lighter grout can show stains more readily; consider epoxy grout for easier maintenance.
