How to Install 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. And, whether you’re replacing a sink in a small bathroom, or looking for an attractive, streamlined option that will show off the style of your entire bathroom, installing a pedestal sink is a project most experienced do-it-yourselfer can tackle in a day.

This guide will show you how to install a new pedestal sink in your bathroom in seven simple steps.

WHAT YOU NEED FOR THIS PROJECT

1

• Follow manufacturer’s instructions for locating the sink brace.
• Cut a hole in the wall spanning from stud to stud, and then cut a piece of 2×8 to fit snugly between the studs.
• (Optional) 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.
