What is the difference between a Glass Vessel Sink, Undermount Glass Sink, or an Overmount Glass Sink?
November 13, 2010

When it comes to glass sinks, what is the difference between a "Vessel", an "Undermount", and an "Overmount" style glass sink?

A Glass Vessel Sink is a glass bowl that sits on top of a counter top.  Sometimes they are also mounted in a free-standing pedestal and sometimes set into the counter top slightly.

An Undermount Glass Vessel Sink, is a glass sink that mounts on the underside of a counter top.  The glass sink is usually held in place by the sinks glass flange.  A bead of silicon seals the gap between the flange and underside of the counter top to ensure no water can get between. Undermount glass sinks are popular with people that want to under or back light their glass sink, but don't want to see the flange of the glass sink.  Though often times more difficult to install, many people feel that having the glass sink installed under the counter top, creates cleaner lines and lends more sophistication.

An Overmount Glass Sink, is a glass sink that sits on top and flush with the counter tops surface.  The glass sink has a special glass flange that sits atop the counter top and keeps the sink from falling into the hole.  Overmount glass sinks are popular with people that want to under or back light their glass sink.  With this type of mounting, you will see more of the sink.
