If you need a 30-inch-wide interior door panel, these five 30-by-80-inch slabs offer different styles, including raised panels and a smooth flush design. They are door slabs, not complete door-frame kits: most listed options do not include a frame, hinges, or predrilled hardware holes. Choose the six-panel BARNSMITH or JUBEST for a traditional look, the BARNSMITH flush slab for a minimalist style, or the two- and five-panel options for other classic designs.
| Product | Best For | Key Detail |

| BARNSMITH 2-Panel | Simple traditional detailing | Trim allowance stated |
| BARNSMITH Flush | Modern, smooth appearance | Paint-ready surface |
| JUBEST 6-Panel | Textured traditional finish | Suitable where sound control is less important |
| BARNSMITH 5-Panel | Alternative paneled look | Primed molded hollow core |
BARNSMITH 30-Inch Raised 6-Panel Door Slab
This BARNSMITH slab measures 30 inches wide by 80 inches high and is 1 3/8 inches thick. Its molded hollow-core construction is described as lightweight and durable. The white-primed surface is ready for DIY painting, and each side can be trimmed by up to 1/4 inch.
Best for: Buyers seeking a classic six-panel design and a paintable slab. It was selected as a traditional option with clearly listed dimensions and trim allowance. Limitation: The slab has no drilled holes for the knob, lock, or hinges. The frame and hinges are not included, so plan for fitting and hardware work.
BARNSMITH 30-Inch Two-Panel Door Slab
This 30-by-80-inch molded hollow-core slab has a two-panel design, a 1 3/8-inch thickness, and a smooth, white-primed surface intended for painting. The listing says each side may be trimmed by 1/4 inch, which can help with a small fit adjustment when the opening and installation permit it.
Best for: Homeowners who want panel detail without the denser look of a six-panel layout. Choose this if the two-panel pattern suits the room and you want a paint-ready interior slab. Limitation: It arrives without hardware holes, hinges, or a frame; those parts and the door preparation are separate.
BARNSMITH 30-Inch Modern Flush Door Slab
The BARNSMITH flush slab measures 30 by 80 inches and is 1 3/8 inches thick. Its smooth, white-primed surface can be painted to coordinate with interior décor. Hollow-core construction keeps the panel lightweight, according to the product information, and each side can be trimmed by 1/4 inch.
Best for: Buyers who prefer a clean, modern surface rather than raised panels. It is the better match for a simple painted interior door design. Limitation: The listing says holes for the knob, lock, and hinges must be drilled. A frame and hinges are not included.
JUBEST 30-Inch Textured 6-Panel Door Slab
This JUBEST slab combines a classic six-panel design with a textured, wood-grain surface. Its white-primed finish is described as paintable with water-based paint or lacquer. The manufacturer recommends sanding with 320-grit or finer sandpaper before painting. The listing describes its molded hollow-core build as lightweight and notes it is suited to areas where sound control is less important.
Best for: Buyers who want a textured traditional look and plan to paint the door. Limitation: The product information does not specify the slab thickness, trimming allowance, or included hardware, so confirm those details with the seller before purchasing or planning installation.
BARNSMITH 30-Inch Five-Panel Door Slab
This BARNSMITH option has a five-panel molded design and hollow-core construction. The listed dimensions are 30 inches wide, 80 inches high, and 1 3/8 inches thick. Its white-primed smooth surface is ready for painting, and each side can be trimmed by up to 1/4 inch.
Best for: Buyers comparing classic paneled looks who want an alternative to two- or six-panel patterns. It offers specific dimensions and a stated trim allowance. Limitation: The slab does not come with holes for hardware, a frame, or hinges; installation requires separate components and preparation.
Buying Guide: Choosing A 30-Inch Door Slab
Do you need a slab or a complete frame?
A slab is the door panel alone. It is not the same as a prehung door, which is supplied with a frame and hinges. The products here are described as slabs, and most explicitly exclude the frame and hinges. If you are replacing a damaged frame as well as the panel, look for a complete door-and-frame assembly instead.
Will a 30-by-80-inch slab fit the opening?
Measure the existing door and the frame opening before ordering. Check the width, height, thickness, swing direction, and hinge positions required for your installation. The BARNSMITH listings specify 1 3/8-inch thickness and up to 1/4-inch trimming per side; do not assume those specifications apply to the JUBEST option. Confirm measurements and allowable trimming before cutting.
Which panel style should you choose?
Raised six-panel designs suit traditional interiors, while a flush slab offers a plain surface for modern rooms. Two- and five-panel patterns provide other paneled appearances. Compare the design with nearby doors if you want a consistent look throughout the home.
What should you know about painting and hardware?
Primed surfaces are intended for painting, but surface texture and preparation differ. JUBEST recommends sanding before applying paint or lacquer. Several BARNSMITH slabs require you to drill the hardware openings yourself. Check your measurements and hardware layout before drilling, and arrange the necessary hinges and frame separately.
Frequently Asked Questions
Are these products complete 30-inch door frames?
No. They are interior door slabs, not complete frame kits. The listed BARNSMITH products exclude the frame and hinges.
Are the slabs exactly 30 inches wide?
The product listings give a width of 30 inches. Measure the existing door and opening before purchasing to confirm the size you need.
Do the doors come with knob and hinge holes?
The BARNSMITH listings state that hardware holes are not included and must be drilled. Check the JUBEST listing for its specific preparation details.
Can these primed doors be painted?
The BARNSMITH surfaces are described as ready for DIY painting. JUBEST says its primed surface accepts water-based paint or lacquer and recommends sanding first.
Which option is best for sound control?
The JUBEST listing says its hollow-core construction is best for areas where sound control is less important. The supplied product details do not provide comparative sound-control measurements for the other slabs.
