was told that my blanco sink will be under-mount on the granite. initially i had chosen the blanco granite stone look type of sink. its much bigger and looks nicer but last min change to this instead due to long term maintenance and another issue which i had read up on.. infact 2, 1st the stains and debris will not easily flow to the hole as its totally flat inside the sink. so u got to clear it every now and than. 2nd, its hard, if u accidentally slip n drop any mug or porcelin bowls there is a high chance of it being broke.
