1. What Are Interior Doors?
Interior doors are essential components of any home, separating rooms while maintaining privacy and style. They come in various materials, designs, and configurations, including:
Types of Interior Doors
Solid Wood Doors – Durable, elegant, and excellent for sound insulation. Common woods include oak, pine, and mahogany 2.
Hollow Core Doors – Lightweight and budget-friendly, with a honeycomb interior structure. Best for low-traffic areas like closets 2.
Solid Core Doors – Made from engineered wood with a dense core, offering better soundproofing than hollow core doors 11.
Glass Panel Doors – Allow light flow between rooms, ideal for living rooms and dining areas 9.
French Doors – Elegant double doors with glass panes, perfect for connecting spaces like dining rooms and patios 2.
Pros of Standard Interior Doors
✅ More Affordable – Slab doors (without frames) cost less upfront 6.
✅ Customizable – Can be stained, painted, or modified to fit existing frames 2.
✅ Variety of Styles – Available in panel, shaker, flush, and louvered designs 9.
Cons of Standard Interior Doors
❌ Complex Installation – Requires precise hinge mortising and frame alignment 3.
❌ Less Structural Integrity – If the existing frame is damaged, the door may not fit properly 7.
❌ Time-Consuming – Hanging a slab door from scratch takes longer than installing a prehung unit 11.
2. What Are Prehung Interior Doors?
A prehung interior door is a complete unit that includes:
The door slab
A pre-attached frame (jamb)
Hinges already mounted
Pre-cut holes for the doorknob and strike plate 611.
Common Uses for Prehung Doors
New Construction – Builders prefer them for quick, uniform installation 3.
Full Renovations – Ideal when replacing both the door and frame 11.
Damaged Door Openings – Simplifies installation in rough or uneven doorways 7.
Pros of Prehung Interior Doors
✅ Faster Easier Installation – Comes pre-assembled, reducing labor time 4.
✅ Better Alignment – Factory-set hinges ensure smooth operation 11.
✅ Weather-Tight (for Exterior Use) – Some models include built-in weatherstripping 3.
✅ More Durable – Less prone to warping or misalignment over time 11.
Cons of Prehung Interior Doors
❌ Higher Upfront Cost – More expensive than slab doors due to included frame and hardware 7.
❌ Heavy Bulky – Harder to transport and maneuver (some weigh over 100 lbs) 7.
❌ Limited Customization – Fewer style options compared to standalone slab doors 3.

Feature | Standard Interior Door | Prehung Interior Door |
---|---|---|
Construction | Just the door slab | Door + frame + hinges |

5. Installation Comparison

Shim Secure – Ensure it’s level before nailing in place 10.

6. Cost Breakdown
Component | Standard Door | Prehung Door |
---|---|---|
Door Slab | $50–$300 | Included |

Hinges Hardware | $20–$50 | Included |
Labor (if hired) | $100–$300/door | $150–$400/door |
Prehung doors save on labor costs but have a higher initial price 611.
7. Final Verdict: Which One Should You Pick?
For quick, no-fuss installation → Prehung doors (best for new builds).

For soundproofing durability → Solid core prehung doors.
Pro Tip:
If you’re unsure, consult a professional to assess your door frame condition before deciding 11.
