Everyone has taken care of the Fab part pretty well so I will weigh in on the sheet stock. Most on this site do not due Swanstone and I know time still has some nightmares, but they have changed alot of things and I have not seen the problems others have seen. With that said the make sheets in 4′ X 8′ in both 1/4″ and 1/2″ (.400 material actually called) I would fab it with out V grooving, but do not see why it would not work
