Installing a Pedestal Sink

 
Most pedestal sinks actually hang from a bracket attached to a mounting brace (or framing) in the wall; the pedestal is only a secondary support. It's likely the process of installing the framing and patching the wall afterward will be more time consuming than installing the sink itself. Take care of brace installation and patching and painting the wall prior to sink installation. You may be able to hide the plumbing behind the pedestal if the plumbing is installed in a tight arrangement and the pedestal is wide. You may decide to hide only the trap and leave the supply lines visible on either side. If you go that route, using ornate stop valves and solid chrome supply tubing will result in an attractive appearance.

Step 1: Install the mounting brace

Step 1: Install the mounting brace Follow manufacturer’s instructions for locating the sink brace. Cut a hole in the wall spanning from stud to stud and cut a piece of 2×8 to fit snugly between the studs. At this point, you may also choose to move the stop valves closer to the trap, in order to hide them behind the pedestal. Attach the brace with angle-driven screws. Patch the hole, sand smooth, and paint.
