Hole for undermounted sink

[vivienz]

I'm looking at ordering my kitchen worktops from Worktop Express and I've never had an undermounted sink before.  I know which sink I'm having, but what dimensions should the hole in the worksurface be compared to the dimensions of the sink itself?

Sink should have a template with it

Undermount sinks are no good for laminate worktops.If they are wood worktops you will need a jig and heavy duty router as edge is on show. The raw edge deteriorates over time .Undermount sinks are best with granite and quartz worktops, they are far more difficult than sit on sinks to fit.

Thanks, chaps.  All sorted now.
