It features tempered frosted glass panels for privacy and a finish designed to resist scratches and moisture. The package includes a hardware kit, and assembly is required. The product emphasizes space-saving benefits (up to 50% space savings) and is suitable for bathrooms, bedrooms, laundry rooms, kitchens, and other areas where a traditional swing door would be impractical.
Kimberly Bay 2-Panel Door Slab (18×80)

This interior door slab from Kimberly Bay features a solid wood core with an 1-3/8 inch thickness. At 18″ x 80″, it is not prehung and has no bore holes, making it a versatile option for custom framing or finishing projects where a specific width is required beyond standard prehung units.
Kimberly Bay Louver-Louver Plantation Slab

Designed with wide 2-inch open louver slats for ventilation, this door slab is primed white and sized at 80″ x 18″. It is not prehung, requiring installation framing that accommodates the louver style and airflow. The open slats support passive cooling and air circulation in spaces where privacy is balanced with ventilation needs.
Kimberly Bay Louver Panel Slab

This interior slab features a louver-panel design with open space between slats for ventilation. The louvers are 1.25 inches deep, and the door is sized at 80″ x 18″ in a primed finish. Like other slabs, it requires a separate frame or prehung assembly for installation, offering a ventilated option for closet spaces or utility rooms.
Buying Guide: Key Purchase Considerations For 16 Inch Wide Interior Doors
- Door type and installation: Decide between prehung doors (complete with frame and hinges) and slabs (door only). Prehung units simplify installation, while slabs offer customization for nonstandard frames or retrofits.
- Width and height accuracy: Confirm the exact opening size. Some products list 16″ x 80″ or 16″ x 84″ while others are 18″ wide. Measure rough opening and consider jamb thickness and swing direction to ensure a proper fit.
- Material and finish: Primed solid wood cores and MDF slabs offer different durability, paintability, and moisture resistance. PVC-coated surfaces provide water resistance and easy cleaning, suitable for high-humidity spaces.
- Ventilation and privacy: Louvered and frosted-panel designs balance air flow with privacy. If ventilation is critical (closets, baths, laundry), choose louver or frosted styles accordingly.
- Hardware and bore preparation: Some doors arrive with no bore holes; plan for hinge placement and lockset alignment. On primed doors, ready-to-paint surfaces require finishing to match room decor.
- Space efficiency: Bifold or folding designs can save space in tight areas while maintaining a visual open feel. Consider track hardware, installation complexity, and door weight when selecting.
- Durability and maintenance: Look for water-resistant surfaces on MDF doors, UV-stable plastics for panels, and scratch-resistant coatings to preserve appearance in active spaces with pets or kids.
- Application context: For living spaces, standard interior slab doors suffice; for closets or utility rooms with limited swing clearance, bifold doors may be preferable even at 16″ widths.
