Undermount versus Overmount

One of the many design decisions in a bathroom remodel is the sink or the lavatory.  This may seem like a small and simple choice but it is important to understand how a sink may change the overall design and functionality of the bathroom.

An undermount sink is installed beneath the countertop.  These sinks come in many shapes and sizes.  Traditionally the sinks are installed in the center of the vanity cabinet.  Usually an undermount sink is more expensive to install because a very specific cutout size is required with little to no room for error.  The cutout must then be polished to match the finish of the countertop.  An option that adds some flair is to add an edge detail to the countertop around the sink cut out.  Many people prefer an undermount sink for its functionality and looks.  An undermount sink cleans much easier than its overmount counterpart.  The countertop cleans and wipes directly into the sink with no edge or barrier to work around.  An undermount sink also offers a low profile clean look with less sink material that is readily visible.

There are many types and styles of overmount sinks.  They come in all shapes and sizes from vessels to square, rectangle and round.  Some overmount sinks have only a small bump or profile above the counter while others add depth and a unique shape.  Overmount sinks can be more expensive for the material but cheaper to install.  Between the two options an overmount sink is definitely recommended for the DIYer.
