Drop-in sinks get their name from the method of installing them: "Dropping" them into a cutout in the countertop. (Obviously, we recommend a more careful placement.) You may also hear them referred to as topmount sinks. Their edges lap the countertop, which is why they are also called self-rimming sinks.
This type of sink is the least expensive and most common option for your kitchen. Installing them is easier than other types of kitchen sinks, because they can simply be set into the counter and attached with caulk or another epoxy.
However, drop-in sinks can make cleaning difficult, as the sink's lip tends to trap food and dirt.
With the exception of stone, most sink materials-including stainless steel, composite, fireclay, cast iron, solid surface and acrylic-easily can be found in drop-in styles. Bar or prep sinks as well as primary kitchen sinks of all shapes, sizes and number of basins.
