Teka Stylo 1B Inset Stainless Steel One Bowl Sink is also named as drop-in stainless steel sink or top-mount stainless steel sink, is a type of sink that is installed from the top of a countertop. It is a popular choice for kitchens and is known for its durability, easy maintenance, and affordability. 

An inset stainless steel sink typically consists of a single bowl, although there are also double bowl options available. It is designed to be dropped into a hole cut out of the countertop, with the rim of the sink resting on top of the countertop surface. The rim holds the sink in place, and the sink's weight is supported by the countertop. This creates a clean and seamless look, as the edges of the sink are usually covered by the countertop material.

Overall, Teka Stylo 1B Inset Stainless Steel One Bowl Sink is a practical and versatile choice for many kitchens, providing a functional workspace while maintaining an appealing aesthetic.
