How do you mount a undermount sink and vanity top. it came as a package for bathroom?
The undermount sinkattaches first to the vanity top. If there are not matching holes already, you’ll be doing some drilling. Fine if you are dealing with Corian, but not fine if it is granite. Be sure to use a drill stop so you don’t go through the top surface. The vanity top would usually be glued down with a silicone adhesive. no other attachment needed.
