Make a kraft paper template of the bottom of the wet bar cabinet. Lay this template over the corner where the cabinet will sit, leaving space for the back walls of the cabinet. Mark the location of the drain and water lines on the template and cut the shapes out of the paper.
Lay the cutting template inside the bottom of the wet bar cabinet and trace the holes onto the wood. Use a hole saw to cut the hole for the drain pipe, and a drill with a spade bit to make the holes for the water lines. Shift the cabinet into position, fitting the drain hole over the drain pipe. Thread the water lines up through the appropriate holes.
The cast iron sink used in this project included a cutting template that makes installation a snap. Determine the desired position in the cabinet for the sink, making sure to leave room for the faucet assembly. Trace the template onto the cabinet shelf, drill a large pilot hole inside the cutout area, and use a jigsaw to cut out the sink shape.
Determine the position for the faucet, making sure it will extend over the sink as desired. Use the template supplied with the new faucet to mark and drill holes for the faucet assembly.
Drop in sink and faucet. Run a bead of caulk around the edge of the sink hole, then carefully slip the sink into position. Thread the faucet supply lines through the holes and attach the faucet assembly to the shelf according to the manufacturer's instructions.
Install a shut-off valve to each water line and attach to the cabinet wall with screws. Hook up the faucet lines to the shut-off valves.
Remove the cap from the drain line. Connect the sink drain to the drain line with PVC pipe, making sure to build in a P-trap to keep sewer gases from entering the house through the drain. Cut the PVC with a PVC saw and dry-fit the pipes. To make the final installation, glue the pipes together using PVC cleaner and PVC adhesive according to the manufacturer's instructions.
In the crawlspace under the house, open the shut-off valves that connect the water lines to the household water supply. Open the shut-off valves under the sink, let the air out of the pipes, and make sure the water is flowing properly. Check the faucet and sink for leaks, adjusting fittings as necessary.
