Wall-mounted sinks have been in popular use in homes for more than a century. Modern models free the floor space beneath and have been designed to conceal the required plumbing lines for a much cleaner look. Whether you are removing a wall-mounted sink for a repair or replacement upgrade, the procedure for removal is simple.
Things You'll Need
Pipe wrench or adjustable pliers
Turn off the water supply to the fixture at the two small water valves mounted on the wall beneath the sink.
Place a small bucket on the floor beneath the water valves to catch any water left in the lines, then disconnect each of the lines with an adjustable wrench. Loosen the hex nuts at the lower end of the lines to detach them from the valves.
Loosen the P-trap connection to the sink's vertical drain pipe by turning the compression nut counterclockwise, using a pipe wrench or adjustable pliers. This will leave the drain trap in place, but free the sink drain pipe for removal.
Remove the sink from its wall-mounting bracket by lifting evenly upward approximately 3 inches from both sides of the sink near the wall. Use a utility knife to sever any caulking between the back edge of the sink and the wall, if applicable, to ease removal.
Detach the sink wall mounting bracket from the wall, if applicable, using an adjustable wrench or screwdriver to remove the mounting bolts or screws.
