what is a slab door

A slab door is a door without a frame, hinges, or other hardware. It is essentially just a slab of material that is cut to fit an entryway, then attached to the door frame and hinges during installation. Slab doors are typically pre-cut for a doorknob. They are ideal for interior doorways as they typically do not require weather-proofing, which, unlike pre-hung doors, does not come installed from the factory. Slab doors can be purchased new, hand-built by a carpenter, or salvaged from antique stores. Slab doors are generally less expensive than prehung doors, as slab doors do not include any hardware or framing. However, the price varies depending on the door’s features, such as the materials used to make the door, solid vs hollow construction, if the door includes clear or frosted glass, and the intricacy of the door’s design. Hanging recycled, vintage, or custom-built slab doors may require additional time and craftsmanship.
