Lay a large sheet of paper on the floor or a flat work surface. Place the sink and the semi-pedestal on their backs on the paper. Follow the manufacturer’s directions for spacing between the sink and the pedestal. Trace around the entire sink and pedestal with a pencil. Trace around openings for fixtures as well.
Center the drawing on the wall where you intend to install the bathroom sink. Center the sink and pedestal over the plumbing pipes. Use a carpenter’s level to ensure the top of the sink is level. Tape the drawing in position with painter’s tape.
Slip a piece of carbon paper behind the drawing. Trace the entire image onto the wall. Locate the top-center position on the sink drawing and mark it.
Insert the top portion of the faucets through the holes in the top of the sink. Secure the faucets with the tightening nuts from their assembly kit. Tighten the nuts by hand, then turn them an additional quarter-turn with an adjustable wrench. Add the supply lines to the hot and cold faucets. Do not over tighten the connections.
Create a snake-like roll of plumber’s putty by rolling a piece between your hands. Encircle the top of the drain opening with this piece of putty. Drop the drain’s tailpipe through this opening, pushing it firmly into the putty to seal it. Wipe off excess putty that oozes out. Attach a nut from the assembly kit to the underside of the tail pipe as it extends from the sink. Do not over tighten the nut.
Drill two pilot holes into the wall, preferably into studs, to insert the sink’s fixing bolts from the installation kit. If you can’t line the holes up with studs, use the anchors supplied in the installation kit.
Screw the fixing bolts into the wall. Leave a sufficient amount of bolt exposed so you can hang the sink from the exposed bolt. Slip the sink onto the fixing bolts, align it with the center mark on the wall and attach the nuts to hold the sink in place. Tighten the nuts by hand, then turn them one quarter-turn with an adjustable wrench.
Connect the hot and cold water supply lines from the faucet to the wall connections. Attach the P-trap to the opening in the wall. Align it with the tail pipe from the sink. Slide the nuts attached to the P-trap over the tail pipe and drain pipes and tighten both by hand.
Drill pilot holes for the semi-pedestal on the wall following the marks you left in Step 3. Hold the semi-pedestal against the wall aligned with the markings from Step 3. Secure the semi-pedestal to the wall with screws from the assembly kit. If the holes don’t align with wall studs, use anchors to secure the screws to the wall.
Turn on water to the sink. Check for leaks. If you see leakage, turn the appropriate connector an additional quarter-turn to tighten.
