Slate tops have become more and more popular over the last decade. These are made especially to order and the slate can be cut to accommodate sinks of all shapes and sizes and draining grooves can also be provided. Also the slate can be predrilled for tap holes.
Splashbacks can also be supplied and these compliment the slate tops.
The customer can provide an accurate drawing or hardboard templates if the walls are out of square to ensure they fit correctly.
Slate Tops require very little fixing as they just need to be put in place. The weight of the slate ensures that is unlikely to move although dowels can be fitted on the underside of the slate if considered necessary
