Grestec Coretone is advanced porcelain technology where colour, and pattern run through the entire body, not just the surface.
Launched at Clerkenwell Design Week, Coretone represents a step forward in porcelain specification, combining mineral-rich composition with depth-driven design to deliver surfaces that perform as beautifully as they look.

By integrating contrasting porcelain “chunks” and pigment variation throughout the full body of the tile, Coretone achieves a level of authenticity, durability, and visual consistency that surface-applied solutions can’t match.
