@onward - I’m excited to hear you are looking at the Blanco Silgranit line. FWIW, I chose the large single with the drain on one side. You can get them so that the drains/disposals are in the middle of the basin, but I really like having it on the side so I can have a pile of dishes in there and still have access to the disposal.
It’s been three or four months now and I’ve never needed to scrub my sink! Just a simple wiping has done the trick and it looks beautiful.
