5. Take off the old lavatory stops. The plumbing for pedestal sinks are exposed, so you'll want all of the plumbing, including the stops to be new. You'll also need to install a new chrome lavatory stop and escutcheon cover.

6. Using two adjustable wrenches, remove the old supply stops from the hot and cold water lines (figure A), and then remove the old escutcheon covers.

7. Apply Teflon tape on both stub outs, and then add new escutcheon covers by sliding the cover over the roughed in water supply.

8. Thread new supply stops on both (figure B) and use a wrench to tighten everything up. Ensure that the inlet valve is in the upright position.

9. Unscrew the old collar nut, and then slide the new p-trap escutcheon cover over the drain hole.

10. Place the lavatory on the pedestal, and then set it in the desired location. Check for level (figure C).

11. Be sure to center the pedestal to the drain hole on the wall.

12. Once the pedestal is centered, use a pencil to mark where the sink will sit against the wall (figure D).

13. Use a pencil to mark where the anchor holes will be drilled in the wall and floor.

14. After the holes have been marked, remove the sink from the area.

15. Install the lag screws into the wood backing behind the wall. Ensure your bit is at least a size smaller than the lag bolts so they'll hold tight in the wall.

16. Drill two 1/4 inch holes for the hanger bolts at the marks on the wall.

17. Thread the hanger bolts into the wall. Leave approximately 1 1/4 inch of each bolt exposed between the cap nuts and the finished wall.
