The 6 inch round dip well would not sit in the counter even. It needed filed down almost a 1/4 inch to sit flush. next the drain assembly had very poor threads and was not long enough to to thread the tail stock on . I had to replace it with a bar sink drain. There were no instructions were to put the faucet. If it is installed to close to the well you can not the remove inner can.
