Karran Edge sinks can be used with plastic laminate, solid surface, or stone countertops. The lip of the sink comes to a sharp 90 degree corner and the lip is specially coated to bond with all types of adhesives for a perfect finish with high pressure laminates, like Formica. Karran Edge sinks are crafted from high quality Type 304, 18/10 stainless steel. All Edge sinks are constructed from heavy 18 gauge stainless steel with a brushed satin finish for long lasting beauty and durability.
