Teka Brooklyn 90 M-XP 2B 2-In-1 Installation Stainless Steel Sink is a type of sink that can be installed in two different ways: as a top mount sink or as a flush mount sink. Stainless steel sinks are popular for their durability, resistance to corrosion, and easy maintenance.  In a top mount installation, the sink is placed on top of the countertop in a way that the edges of the sink overlap the countertop.

The sink's rim or lip rests on the countertop surface, creating a visible edge around the sink. This method is relatively easier and more common, making it a popular choice for many kitchens. The flush mount installation creates a seamless and sleek look, as the sink is positioned below the countertop surface. The edges of the countertop are cut to fit the sink precisely, resulting in a smooth transition between the sink and the countertop.
