To create a bedroom vanity in a small alcove, install a narrow floating shelf about twenty-four inches deep for the tabletop surface and add a comfortable chair or stool. Position a well-lit mirror, preferably with arched or stylish framing, and add a warm sconce light around three thousand kelvin for flattering illumination. Use outlets if available for devices like hair tools or lights. Keep storage minimal with drawers or open shelves underneath the vanity to prevent crowding the space and maintain an inviting atmosphere.
