An interior door slab is a door panel sold without a frame, hinges, or hardware — just the door itself, sized to drop into an existing jamb where the frame, stop, and hinge mortises are already in place.

A door slab is the right choice when the existing frame is in good condition and only the panel needs replacing. Because the slab ships without a frame, it costs less and installs faster than a prehung unit — but it requires a jamb that is square, intact, and properly shimmed. WIN STELLAR interior door slabs ship paint-grade primed with a solid core CARB P2 certified MDF construction, meaning they drop into a standard frame ready for paint.

  • An interior door slab includes no frame, no hinges, and no hardware — panel only.
  • WIN STELLAR door slabs use solid core CARB P2 certified MDF construction, not hollow-core.
  • Door slabs require an existing frame in good condition; a damaged or missing jamb requires a prehung unit instead.
  • WIN STELLAR slabs ship paint-grade primed — a finish coat matches any interior trim color exactly.
