Determine where support will be needed, based on the sink’s measurements and mounting height (typically 30 inches above the floor). Remove drywall in that area and install 2-by-6 or 2-by-8 blocking between wall studs.

Drill holes for screws and fasteners.

Drill holes for screws and fasteners.

Toenail the blocking to the studs with 3 1/2-inch galvanized common nails. Then repair the drywall.

1Position the mounting plate or sink on the wall and mark the wall through the holes in the plate or sink. Drill pilot holes for lag screws or other fasteners supplied by the manufacturer; if the wall is tile, use a masonry bit.

Then install the faucet and drain and pop-up assemblies on the sink (see step 3 of Install a Countertop Sink and steps 4, 5, and 6 of How to Install a Bathroom Faucet.

Secure the sink or mounting plate to the wall.

 

2Use lag screws or other fasteners recommended by the manufacturer to secure the sink or the sink’s metal mounting plate to the blocking. After driving in the first fastener, check to make sure the sink or mounting plate is level, then drive in the other fasteners.

 

Connect

Connect the P-trap and water supply lines.

3Connect the P-trap and drain arm to the drain stub-out, then connect the two water-supply tubes to the shutoff valves.

Some wall-mounted sinks (like the one shown here) come with a trim piece that hides the plumbing lines. These typically attach directly to the wall framing with lag screws.
