A slab door is just a basic, rectangular, flat, slab of wood, steel or fiberglass that’s sold without any hardware, hinges or frame. Slab doors may or may not have pre-drilled holes for door knobs, and the hinges will need to be mortised out.
But just because you order a slab door doesn’t mean you have to get something that’s boring. Slab doors can have glass or ornate moldings, can be flat or paneled and can be used for interior or exterior entryways.
