After identifying the location of the underlying wall studs, line up the back of the cabinet to its new location and mark holes for water and drain lines. Drill using a spade bit and a hole-saw attachment to create holes for the plumbing.
Fit the cabinet in place over the pipe stubs (Image 1).
Then, checking frequently with a level, use wood shims to raise and adjust the position of the cabinet (Image 2). Later the shims will be cut flush and covered with a trim piece.
With the cabinet positioned properly, drive two screws in through the back of the cabinet and into the wall studs marked earlier.
Once the cabinets are secured, hide exposed gaps with trim pieces included with the cabinets.
