Step 2: Installation of the sink
First - Mark the exact center of the piece. Always measure twice, cut once! Now take a hole saw bit and drill in the correct size hole for the drain. Mine had to be at lease 1-1/4" so I went to 1-1/2". This part will take some problem solving if you have a drawer here. I took it out at first.
Second - Assemble the sink per the instructions that came with them. Mine came with a free pop-up drain, so there was nothing too hard about this part. Ensure that you have the water tight washers in the right spot, otherwise the sink could leak making you disassemble everything.
Last - Have a dry run. Put the sink in place and make sure you like how everything fits.
