TopZero sinks are in a class of its own, all thanks to the smart engineering that went into the making of the product. The look of the sink is like nothing else in the market. Unlike any undermount sink, the rimless edge of TopZero is flush against the countertop surface, giving it a sleek look with infinity pool like appearance, as well as cleanliness. All credit goes to the proprietary rimless / seamless edge. The joint between the countertop and TopZero sink is filled with acrylic sealant, preventing water or debris from entering the union of the stainless steel to the solid countertop. Modern look and hygienic advantage of TopZero is totally exceptional.
