TIP: 1st, we updated the builder grade cabinet into a floating vanity raised to a 33″ height; reversed the doors to take advantage of the Shaker style on the other side; and beveled the drawer fronts edges, removing the curved ogee edge with an orbital sander so they were refinished as curved and smooth. Painted vanity Silver Marlin by Benjamin Moore, it has a green undertone.
Replace your knobs and pulls with vintage hardware. Hardware (whether for doors or cabinets) is a little thing that can have a big impact. (Case in point: this project by Jessica Helgerson Interior Design.) You can buy new hardware that just looks vintage, or scour architectural salvage shops for inexpensive pieces to replace your boring, builder-grade stuff.
