Installed a few weeks ago. Simple to install each component. If Installing in stone, you will need a 1-3/4" carbide hole saw for the drain and a 1-3/8" carbide hole saw for the faucet. Plan the location of the sink and faucet for clearance purposes. Pre-plan and locate the components and you'll be OK. I am very happy with these items and I'm the only one on the block with one!
