Corner-sink cabinet 36''or 42''for 33'' undermount
Would anyone know the answer to this question? We are using a Silgranite 33'' single-bowl undermount sink. It will be installed in a corner cabinet. According to the Blanco site below, they indicate using a 36" base for a 33'' sink. This would give us another 6 inches to add to our other base cabinet. I certainly don't want to order the 42" if it isn't necessary. However, a granite salesperson and our KD told us we need at a minimum of 7 extra inches in a cabinet over the size of our sink. If that's true then I do need a 42" sink base and not a 36 inch. Is the measurements on the Blanco site wrong?
