We are having an undermount sink put in and asked for it to be flush mounted with the countertop so there would be no rim of sink showing. However, the Silestone folks tell us it is almost impossible to get it exact. Does anyone have any thoughts on which way is best? I just thought I would constantly be wiping that rim if it was there, plus it seems like it would catch all crumbs and stuff being wiped off the counter into the sink.
