The Xtra worktop has a distinct 3D surface texture and an authentic looking natural stone appearance. Its multilayered composition allows for easy flush-mounting of sinks and hobs. The robust and impact-resistant surface consists of a particularly strong coating material on top of a 9.4 mm thick functional layer that markedly increases the water-resistance of the worktop. This ensures that water cannot penetrate into the worktop and so prevents it from swelling.
