The mounting flange has a longitudinal axis that is parallel to the longitudinal axis of the at least one wall stud and a thickness from about inches to about 2 inches. The distal portion of the first mounting flange abuts at least one sheet of drywall. The mounting flange does not substantially overlap the at least one sheet of drywall, and the at least one sheet of drywall does not substantially overlap the mounting flange.

A cove base support is configured to be positioned between a wall and a cove base and includes a vertical support portion, an angled support portion, a toe support portion, and a horizontal support portion. The angled support portion is positioned at the bottom of the vertical support potion and provides a transition to the toe support portion. The toe support portion extends downwards and away from the wall and is configured to provide support to a toe of the cove base. At least one of the vertical support portion and the toe support portion defines a plurality of apertures through which adhesive is placed to attach the cove base support to the wall through the apertures. The horizontal support portion extends horizontally from the toe support portion and may include an antimicrobial material.
