The gorgeous gray and gold veining in the Minera 24x48 Marble Look Polished Porcelain Tile is what gives it warmth as well as visual interest. These veins have a dreamy look that creates a compelling sense of cloudy movement in your floors and walls. The oversized format and reflective, polished finish add to the look of luxury. Minera is produced with a commitment to environmental responsibility. Its production facility recycles and reuses waste materials and prioritizes renewable energy sources to minimize its carbon footprint. These efforts have resulted in LEED certification for the factory. Additionally, the anti-allergenic Minera is also certified for clean indoor air quality.
