My contractor works with the countertop place who sold me a Hi-Macs solid surface vanity. When I wanted a Kohler undermount sink they made it sound like that was very unusual and they wanted to charge me $150 to install the sink onto the countertop. What they ended up doing is making a plywood deck that the sink sets in then the countertop sets ontop of this. It's not installed yet so I don't know how it will turn out.
question is...what's the usual way to install a porcelin undermount sink onto a Hi-Macs countertop? The kohler documentation says "no epoxy" and to use the countertops recomendation for attachment.
