Wall-hung floating cabinets require in-wall blocking
NKBA 4th ed §4.1 Cabinetry & Casework PlanningDescription
Wall-hung (floating) cabinets require wall-blocking, mounted brackets, or other mechanisms to carry the combined load of the cabinetry, countertop, fixtures, and the activity weight on top. Specify the blocking with the framing package so it's in place before drywall.
Why this exists
Floating-cabinet failure is one of the most-cited renovation defects. The load path goes through the back of the cabinet into the studs — a fastener missing the stud renders the cabinet a fall hazard. In-wall 2x blocking, specified at design time, gives every fastener a solid backer.
