Types of Interior Doors
Interior doors help ensure privacy, reduce noise and can also hide rooms or areas that are untidy. Interior doors come in a wide variety of styles, which makes it easy to match or complement an existing trim and finish in your home's decor.
This guide will walk you through the different types of interior doors so you can find the one best suited to your needs. Choose between slab, accordion, bi-fold, barn, French doors and more.
Tip: Specific rooms, such as bathrooms, bedrooms and closets require different door functionality, so be sure to consider where you will be installing your new door and its appearance before making your purchase.

|slab doors||Panel doors, also known as slab doors, contain patterns of square or oblong panels and are a classic choice. A door may contain two large panels, six small ones or some other configuration. Choose panels with straight or curved tops to suit your decorating needs.|
|accordion doors||Accordion doors are ideal for closets and entryways with space constraints. They may consist of a few large panels or multiple small panels that fold in on themselves and rest against one side of the door opening.|
|bi-fold doors||Bi-fold doors are a good option for closets, laundry rooms, pantries, storage rooms and other smaller spaces in your home. Choose bifold doors that fold back to one side of the opening, or bifold doors that fold back to both sides of the opening.|
|barn doors||Barn doors offer a classic, rustic look. They hang from a top rail, allowing them to slide over door openings.|
|french doors||Gorgeous French doors brighten any room. They come in a variety of sizes, wood types, styles and glass pane configurations.|
|sliding doors||Wooden or mirrored sliding doors are a good choice for closets. They use space economically, and mirrored doors do double duty. Large mirrors also make a room appear more spacious.|
|cafe & saloon doors||Swinging hinged doors or cafe doors can add easy flow from room to room while maintaining privacy.|
|hidden doors||Hidden doors are becoming more popular in homes. They provide added security as well as a touch of whimsy to a room. They usually take the form of an outer bookcase that slides or rotates to reveal a hidden room entrance. However, these doors can be created customized to encompass more elaborate designs.|
|prehung doors||Prehung doors come with hinges in their own frame, ready to fit into your doorway.|
Standard interior doors aren't all alike. Panel doors and flush doors are constructed in one of three ways: of solid wood, with a solid core or with a hollow core.
Tip: The Home Depot does not apply paint, stain or varnish to doors. To maintain your door's warranty, you should seal and finish your door soon after it is installed. If you prefer, you can special order interior doors that come already painted, stained or finished.

Complete your door's look by choosing hardware to match your home’s decor and your personal style.
Passage door knobs or handles come in an extensive array of styles, materials and finishes, such as polished chrome, nickel, antique brass, bright brass and more.
If privacy is not an issue, an interior door may not need a lock. However, bedroom and bathroom doors usually need privacy locks. These locks have a locking button on the knob that's inside the bedroom or bathroom. To prevent someone from being locked in the room, the locking button can easily be picked open with a tiny screwdriver or paper clip.
Before installing, determine the door swing direction and handle placement. Replacement doors should have the same measurements as old doors.
- 1 - 3/8 inches is the most common depth, but other depths are available.
- Standard widths include 18, 20, 24, 28, 30, 32 and 36 inches; standard heights include 80, 84 and 96 inches.

- To measure a prehung door, remove the interior casing and measure the opening.
