The most common type of kitchen sink, the drop-in installs from above. Stainless steel is commonly used in kitchens and commercial applications because it represents a good trade-off between cost, usability, durability, and ease of cleaning. Drop-in sinks are DIY-friendly. No special skills are needed, as long as the hole in the counter is already cut. This style of kitchen sink is designed to be dropped into a hole in your counter top. Drop-in sinks always have a rim or lip that hold the sink in place and creates a finished look.
