KHSHOW 36×80 White Exterior Front Door Slab
Best for: homeowners replacing an exterior door who want privacy and daylight. This pre-bored slab is designed for standard 36×80 openings and includes pre-drilled hinge locations and ready-for-handle cutouts. The frost glass panel brightens entryways while maintaining privacy, reducing the need for blinds or curtains near the door.
Why selected: It offers a complete one-piece slab with hinge and hardware alignment considerations already accounted for, making installation simpler when the frame is compatible. The frost glass helps balance daylight with privacy for curb appeal and energy considerations.
Caution: hinge placement must match your existing frame; incompatibility can require additional modifications or hardware repositioning.
JUJUBON Slab Door Interior, 18″x80″
Best for: smaller interior openings or space-saving renovations where a light, paint-ready slab is ideal. The 18″ width is suited for tight hallways or pantry corridors that require privacy with a solid core for noise reduction.
Why selected: CARB P2 certified MDF ensures quality materials and easier maintenance. The door is preassembled as a panel and requires painting after sanding, offering a straightforward DIY finish.
Caution: hardware kits and frames are not included; plan for separate hinges and hardware that fit the door’s bore pattern.
JUJUBON Slab Door Interior, 30″x80″
Best for: mid-size interior spaces needing a solid-core, paint-ready slab. This 30″ door is another size option for standard 2-3 panel configurations in interior layouts.
Why selected: CARB P2 certification and the option to trim up to 0.5 inches allow a precise fit when exact openings aren’t standard. The door comes with no hardware, enabling full customization of hinges and handles to match interior decor.
Caution: like other interior slabs, hardware must be purchased separately to match bore holes and hinge positions.
Generic 36×80 Black Fiberglass Exterior Slab
Best for: exterior upgrades that prioritize durability and low maintenance. This slab is designed for an exterior opening with privacy glass and a modern black finish.
Why selected: reinforced stiles help prevent warping and temperature-related deflection, while low-maintenance vinyl brickmould and a durable finish simplify upkeep over time.
Caution: always verify hinge and bore alignment with your existing frame, as exterior slabs may have different hinge configurations than interior slabs.
JUBEST 36″x80″ Left-Hand Prehung Interior Door
Best for: interior spaces where a prehung, hollow-core door with ready-to-paint surface is beneficial. This 36″ slab variant includes a jamb kit and hinges, but the handle must be added separately.
Why selected: offers a ready-to-assemble option with a paint-friendly primed surface, suitable for customization to match interior color schemes. The included jamb kit speeds up installation compared to separate frame sourcing.
Caution: handle not included; ensure your hardware matches the bore pattern and hinge cutouts for a smooth install.
WIN STELLAR 36×80 Interior Slab Door
Best for: interior upgrades seeking a budget-friendly, multi-use slab that can serve as a pre-hung option with a DIY approach. The natural pine surface is ready for staining or painting.
Why selected: solid natural knotty pine gives a warm look and durable core. The slab can be used as a door for various configurations like barn, pocket, or French doors when paired with a suitable frame and hardware.
Caution: once installed, the surface is unfinished and requires staining or painting; hardware is not included.
Buying Guide
What should you check before buying a pre bored slab door?

Yes, DIY installation is common when you select a slab with predrilled hinge cuts and the correct measurements. Plan for trimming if necessary and ensure proper alignment of hinges and strike plate.
