Your Guide to Buying Internal Doors Online: Styles, Materials, and Types
When you buy internal doors online, you’re choosing pieces that define your home’s character. The right door can lift your entire space. Let’s walk through the key choices.
Popular Interior Door Styles for Every Home
Shopping online reveals styles you might never see locally. Each one tells a different story.
Shaker doors offer clean, simple lines that work in nearly any home. Their flat panels and sturdy frame create a timeless look. Our Interior Doors – 1 Panel Shaker is a customer favorite.
Panel doors are a classic, with raised or recessed panels that add depth and shadow. The Interior Doors – 6 Panel is a traditional standard.
French doors use glass panels to share light between rooms, creating connection and elegance. They are perfect for home offices or dining rooms.
Barn doors slide to save space and add character, from rustic farmhouse to sleek industrial. They are a great solution for pantries or master bathrooms.
Flush doors are completely smooth and flat, blending into walls to let your decor take center stage. Our Interior Doors – Flush collection proves simple can be stunning.
Modern doors feature geometric patterns and creative designs. Our Modern Interior Doors collection turns a doorway into a design moment.
Traditional doors feature ornate moldings and raised panels, adding a sense of history, while Rustic doors celebrate natural imperfections like knots and distressed finishes for a warm, authentic feel.
Choosing the Right Door Material: Pros and Cons
Your material choice affects durability, sound insulation, and cost.
Solid wood (oak, pine, etc.) offers the best durability and sound blocking but is the priciest option. It can be stained or painted.
MDF (Medium-Density Fiberboard) is a stable, popular choice that won’t warp. Its smooth surface is perfect for painting and offers good sound dampening at a mid-range price.
Hollow core doors are lightweight, budget-friendly, and easy to install, making them ideal for closets where sound insulation isn’t a priority.
Solid core doors provide excellent sound insulation and durability, offering a great balance of performance and price for bedrooms and offices.
Composite doors are made from a blend of materials, making them highly resistant to warping, splitting, and moisture.
Glass panels in French or glazed doors allow light to flow between spaces, though they offer minimal sound privacy.
| Material | Cost | Durability | Sound Insulation | Best Use Case |
|---|---|---|---|---|
| Solid Wood | High | Excellent | Excellent | Bedrooms, offices, high-traffic areas, luxury homes |
| MDF | Medium | Good | Good | Painted doors, modern styles, stable environments |
| Hollow Core | Low | Fair | Poor | Closets, utility rooms, budget projects |
| Solid Core | Medium | Good | Good | Bedrooms, bathrooms, offices, sound privacy needed |
| Composite | Medium-High | Excellent | Good | High-traffic, moisture-prone areas |
| Glass | Varies | Fair-Good | Poor | Living rooms, dining rooms, light flow, aesthetics |
Understanding Door Configurations and Special Types
Slab doors are just the door, without a frame or hardware. They are ideal for replacing a door in an existing frame but require more installation work.
Pre-hung doors come as a complete package: door, frame, and hinges. Our Pre-Hung Doors simplify installation, especially for new construction.
Bifold doors fold in on themselves, perfect for wide closet openings in tight spaces.
Pocket doors slide into the wall, saving maximum floor space. They are great for small bathrooms but require more complex installation.
Fire-rated doors are specially constructed to slow the spread of fire and smoke, often required by code between a house and an attached garage. They are rated for specific time periods (e.g., 20 or 30 minutes).

How to Measure and Specify Your Doors for a Perfect Fit
Getting measurements right is the key to a smooth installation when you buy internal doors online. An accurate measurement prevents the heartbreak of a door that doesn’t fit.
Step-by-Step: How to Measure for a New Interior Door
The process differs for slab doors versus pre-hung units.
For Slab Doors (replacing the door only):
- Height & Width: Measure your old door’s height and width at three points (left, center, right). Use the smallest measurement for each.
- Thickness: Measure the door’s thickness (usually 1-3/8″ or 1-3/4″). This must match exactly.
- Hardware: If reusing hardware, measure hinge locations from the top of the door and the doorknob’s backset (distance from edge to center of the hole).
For Pre-hung Doors (new door and frame):
- Rough Opening Height: Measure from the subfloor to the bottom of the header beam.
- Rough Opening Width: Measure between the wall studs at the top, middle, and bottom. Use the shortest measurement.
- Jamb Width: This is your wall’s total thickness, including drywall. This is a critical measurement; common sizes are 4-9/16″ for 2×4 walls and 6-9/16″ for 2×6 walls, but always measure your own.

Pre-Finished vs. Unfinished: What to choose when you buy internal doors online
This choice balances convenience and creative control.
- Unfinished doors are raw material, offering total customization for staining or painting. They require sanding, priming, and finishing, which is more work but allows for a perfect match with existing trim.
- Primed doors come with a primer coat applied, ready for your final paint color. This option saves significant prep time.
- Pre-finished doors are the most convenient, arriving painted or stained and ready to hang. The factory finish is highly durable, but your color choice is limited to what’s offered.

Getting the Details Right: Handing and Swing
Getting the door handing wrong is a common mistake. To determine the handing, stand where you can see the hinges when the door is closed.
- Left-Hand Inswing: Hinges are on the left, and the door swings into the room, away from you.
- Right-Hand Inswing: Hinges are on the right, and the door swings into the room, away from you.
A simple trick: if you push the door open with your left hand, it’s a left-hand door. If you push with your right, it’s a right-hand door. Double-checking this detail prevents costly returns.

Understanding Costs and Shipping When You Buy Internal Doors Online
Here’s what to expect for pricing and delivery.
Price ranges vary by material. Hollow core doors are most affordable ($25-$100), while MDF and primed doors are mid-range ($75-$250). Solid core doors offer great value ($150-$400), and solid wood doors are a premium choice ($300-$800+). Specialty doors like French or barn doors can range from $200 to over $2,000.
Shipping costs are a key part of your total investment. Look for flat fees, free shipping offers on large orders, or local delivery discounts.
The delivery process can be curbside or “white glove” (brought inside). For heavy doors, the extra service is often worth it.
Inspection upon arrival is critical. Before signing the delivery receipt, check for any damage to the packaging or doors. Note any issues on the receipt and take photos to protect yourself in case of a claim.
Latest Trends and Finishing Touches
A new door is a chance to refresh your home’s personality. When you buy internal doors online, you’re making a style statement.
2024 Interior Door Trends: What’s In Style?
This year’s trends offer exciting ways to transform your space.
- Minimalist Designs: Clean lines and smooth surfaces are in, with frameless invisible frame doors offering the ultimate seamless look.
- Bold Dark Colors: Black, charcoal, and deep gray doors create stunning contrast against light walls for a touch of modern sophistication.
- Natural Wood Finishes: The warmth of real wood grain remains popular, from light oaks for a Scandinavian feel to rich walnuts for luxury.
- Taller 8-Foot Doors: Moving beyond the standard 6’8″ height, taller doors make ceilings feel higher and add a sense of grandeur.
- Custom Carved Doors: Intricate patterns turn a door into a functional art piece and a memorable conversation starter.
- Shaker Style: This classic continues to be a top choice, as its clean lines work beautifully in both traditional and contemporary homes.
Don’t Forget the Hardware and Maintenance
Hardware is the jewelry for your doors. The right choice completes the look.
Hardware Selection:
- Handles and Knobs: Choose from modern lever handles or classic knobs. Finishes like matte black, brushed nickel, or polished chrome should complement other fixtures in your home.
- Hinges: Ensure hinges are strong enough for your door’s weight and match your handle finish for a cohesive look.
Maintenance Tips:
- Cleaning: Use a soft, damp cloth. Avoid harsh chemicals. For stubborn scuffs on painted doors, a magic eraser can work wonders (test in a hidden spot first).
- Wood Doors: Use a wood-specific cleaner for stained doors. Mild soap and water work for painted wood.
- Hardware Care: Periodically tighten loose screws and lubricate squeaky hinges with silicone spray.

Frequently Asked Questions about Buying Interior Doors
When you buy internal doors online, a few common questions arise. Here are clear answers to help you shop with confidence.
What’s the difference between a slab door and a pre-hung door?
A slab door is just the door panel itself, with no frame, hinges, or hardware holes. You would choose a slab when your existing door frame is in good shape and you’re just swapping the door. This option requires more skill to install, as you’ll need to mortise for hinges and drill for the doorknob.
A pre-hung door is a complete package. It includes the door panel already hanging on its frame with hinges attached. This is the ideal choice for new construction or when replacing the entire frame, as it simplifies installation and ensures a perfect alignment.
How do I know if I need a fire-rated door?
Fire-rated doors are a critical safety feature designed to slow the spread of fire and smoke. They are often required by building codes in specific locations.
The most common place you’ll need a fire-rated door is between your home and an attached garage. You may also need them for the entrance to a condo or apartment unit. These doors are rated to resist fire for a specific duration, such as 20 or 30 minutes (often marked FD20 or FD30). Always check your local building codes to be sure; you can find more information on standards from organizations like the International Code Council. It’s a small investment for a crucial safety measure.
Can I paint a pre-finished door?
Yes, but it requires significant prep work. The durable factory finish must be thoroughly cleaned, lightly sanded, and then coated with a high-quality bonding primer before you can apply your paint. Skipping these steps will result in a poor finish that peels easily.
More importantly, painting a pre-finished door will likely void the manufacturer’s warranty. If you want a custom paint color, it’s much better to buy an unfinished or primed door. This will save you work, ensure better paint adhesion, and keep your warranty intact.
