Before beginning, have a professional fabricator cut the sink hole using a template. Sink bowls come in varying sizes and arrangements so you can select the configuration that best meets your needs. Think about your fixtures too. Do you want a double-handle or single-handle faucet? What about a soap dispenser? Since the weight of the sink is supported from the underside, you'll need a solid surface countertop such as granite or marble.
Place a 2x4 across the countertop, clamp the sink to the underside and adjust the placement. Thread the wing nuts onto the screw heads. Test fit your sink and mark the location for the mounting clips. With the sink out, drill 1/4" holes for the brass inserts and tap them in. Clean the ridge with denatured alcohol. Run a bead of silicone sealant around the edge, and re-clamp the sink in place.
Thread the wing nuts onto the screw heads and tighten the screws to anchor the inserts. Hand tighten the wing nuts to secure the bowl. After removing the clamps, place masking tape across the back of the countertop and mark the layout for the faucet holes. Drill the holes using a 1-1/4" diamond coring bit. Allow it to cure overnight before installing your plumbing.
