Do you have an installation guide for your sinks?
We recommend using a licensed contractor / licensed plumber to install sinks and drains and have installation guides for you to share with them. Please note, installation of your sink is considered acceptance of your order.
Are they overmount, undermount? Can it be overmounted?
Both can be mounted over or under your counter, depending on what works best for you.
How do you mount a polished copper or polished brass finish sink when it does not have rail clips?
To mount without clips, use silicone around the rim and attach it to the countertop underneath. If you have further questions regarding your install, we recommend consulting your local licensed/qualified contractor to assist.
