For ease of posting, 10mm depth samples are sent


Brazilian black calibrated slate tiles have a beautifully even riven textured surface. Natural tonal differences ranging from mid grey through to Charcoal and black ensures that each tile is completely unique. Calibration provides a machined flat back to aid fitting onto walls or floors.

Suitable for both internal and external use and great for bathrooms/ wetrooms due to its fantastic anti-slip rating. Great for areas with the heaviest of footfalls. Machine cut edges provide a contemporary look.
