When it comes to building, renovating, or simply upgrading your living space, interior doors play a much bigger role than many people realize. They don’t just separate rooms—they define style, influence acoustics, and affect privacy and flow.
Years ago, interior doors in a home usually all looked the same. But today, with the growing popularity of transitional and custom home styles, doors come in many finishes, materials, and designs. That gives homeowners much more freedom to mix, match, and personalize their interiors.
Whether you’re outfitting a single room or your entire house, understanding the different types of interior doors will help you make smart, stylish decisions—and avoid costly mistakes.

Panel Doors & Door Frames – Structure Explained
In traditional panel doors:
- The panel is the central part that can be raised, recessed, or flat.
- The frame outlines the panel and provides structural strength.
- Doors can be single-leaf or multi-leaf, affecting both appearance and practicality.
