Good Morning Michael,

Thank you for your inquiry.

We do not recommend installing it as a drop-in as our undermount sinks are designed only for an under mount installation. We also recommend using the mounting hardware that is included with this sink to ensure it is being secured correctly.

Failure to do so would result in the warranty being voided as well.

If you are interested in a topmount granite sink we do offer the following alternatives for your considerations.
