The Prescious Grey Onyx Marble Effect Large Polished Porcelain Tiles 120x60cm combine the visual richness of onyx with the strength and practicality of porcelain. Their polished surface enhances light reflection, helping interiors feel brighter and more open. The grey marble effect design adds natural depth and variation, offering a premium look without the ongoing care required for real stone. With their large 120x60cm size, these tiles minimise grout lines for a more continuous, flowing surface. Rectified edges allow for precise installation with slim joints, giving a sleek and modern finish across both walls and floors.
