Jockey the corner cabinet into position. Shim it up from the floor until its back edge meets the layout line. If there are plumbing lines, push the shimmed cabinet against them and mark their locations on its back panel. Turn the cabinet around and drill holes through the back with an appropriate-size hole saw. Using a level, check the face of the cabinet for plumb. If it's not plumb, insert shims between the floor and the bottom of the cabinet, or between the wall and the back of the cabinet, at the stud locations. Check that the top of the cabinet is level, and add shims underneath as necessary. With the cabinet seated against its shims, drive 2½-inch deck screws (with washers) through the cabinet back and into the studs. At the shim locations, counterbore and fasten cabinet to the floor with deck screws (without washers).

    Catalyzed lacquers or conversion varnishes are toughest

    3. Fasteners
    Screws are best, but staples ad brads are typically used

    4. Drawers
    Dovetail joints and fully extending drawer slides are best
