The package includes the door slab only, with no frame or hinges, so you can select a compatible frame kit or existing hardware. The standard 36″ x 80″ size fits most interior openings, and slight trimming is possible to fine-tune fit.

This heavy-duty metal door frame kit features a 3″ throat depth and a standard 83″ overall height, designed for easy transport and assembly. It includes a precise strike jamb location for secure latching. The knock-down design facilitates installation in spaces where framing might be irregular or where a prehung setup is not feasible. It pairs well with a compatible door slab or system for a complete interior door solution.
SMARTSTANDARD 36in x 80in Sliding Barn Wood Door
Natural spruce wood provides a decorative, rustic finish with a smooth surface suitable for DIY painting or staining. The door is pre-drilled for easier assembly, and the bottom groove accommodates floor guides for sliding doors. Please note that some natural wood gaps may appear between boards after installation, which is normal as wood expands with humidity. The kit does not include the sliding hardware, which must be purchased separately.
JUJUBON 36″x80″ Solid Core Paintable Wood Door Slab
This JUJUBON door slab uses CARB P2 certified MDF with a solid core for enhanced privacy and noise isolation. The surface is paint-ready after light sanding, and the door can be trimmed up to 0.5 inches per side to fit non-standard openings. As with other slabs, hardware and frame components are not included, enabling flexible frame pairing for different interior styles.

It is designed for doors up to 36″ wide and 81.6″ high, delivering a quick, clean installation path for interior frames. This kit reduces the need for on-site framing work and supports a consistent finish across rooms.
Buying Guide
Key considerations when selecting a 36-inch interior door with a frame include:
- Material and core: Solid core doors provide better sound control and durability; hollow core doors are lighter and easier to install but may be less soundproof.
- Frame options: Decide between door slabs you’ll pair with a separate frame kit or full prehung frames that include hinges and jambs for faster installation.
- Finish readiness: Primed, paintable, or unfinished surfaces affect painting time and required prep work. Consider whether you want ready-to-paint options.
- Hardware compatibility: Confirm whether hinges, strikes, and knobs are included or must be purchased separately, and ensure alignment with your opening.
- Installation environment: Sliding versus swinging doors have different space requirements and hardware needs. Budget for hardware and track systems if choosing a sliding door.
- Dimensional tolerance: Verify door thickness and trim allowances to ensure a proper fit in your opening, especially in older homes with non-standard frames.
- Maintenance and cleaning: Choose surfaces resistant to moisture and easy to clean for bedrooms, bathrooms, or closets where humidity varies.
Choosing a door and frame combination that aligns with your opening size, desired finish, and installation approach helps ensure a long-lasting interior door solution that fits American homes and style preferences.
