Irregular double bowl to single bowl

I hated having a double bowl sink after having a large single bowl at my last place. Damn I lived with the double bowl for too long!!! I spent months trying to find a single bowl irregular that would slip in but everything was cost prohibitive. Finally bit the bullet and bought a sink like I wanted along with a diamond blade for my grinder to square up the hole. Was a great one day project I should have done a long time ago!
