What are undermount sinks?
Undermount sinks install from below the counter, and thus have no rim that is visible to the naked eye. It attaches to the bottom of the counter, making it aesthetically pleasing and having hidden edges. They’re easier to clean and conserve a lot of space, especially around the countertop adjacent to it.
They are best compatible with solid surface countertop materials like marble, soapstone or granite. However, if you have a laminate or tile countertop in your kitchen you may be better off using another style of sink.
