Hollow Core vs Solid Core vs Panel Doors: A NYC Buyer's Guide

Replacing an interior door sounds simple until you are standing in the aisle deciding between three kinds that all look similar. At New York Paint & Hardware, a family-owned shop on 1st Ave since 1986, we help Upper East Side neighbors pick the right door every day. Here is the plain-English version of hollow core, solid core, and panel, and how to know which one you actually need.

Hollow Core Doors

A hollow core door has a thin wood or fiberboard skin over a light honeycomb interior. It is the lightest and most affordable option, easy to hang, and simple to trim to fit. The trade-off is that it blocks less sound and feels less solid when you knock on it.

Best for: closets, pantries, and bedrooms where cost and easy installation matter more than soundproofing. For a lot of NYC apartments, hollow core is the practical, budget-friendly pick.

Solid Core Doors

A solid core door has the same smooth skin but a dense, engineered wood-composite core inside. That core makes it heavier, quieter, and far more substantial. It muffles sound between rooms, resists dents, and simply feels like a quality door.

Best for: bedrooms and bathrooms where you want privacy and quiet, home offices, and any door where a hollow core feels too flimsy. In a building where you can hear the next room, a solid core door is the upgrade people notice most.

Panel Doors (and Flush Doors)

Panel and flush describe the look of the door, not what is inside it. A flush door is flat and smooth, clean and modern, and it can be hollow or solid core. A panel door has raised or recessed sections, the classic two-panel or six-panel look you see in prewar buildings and brownstones. Panel doors add character and are the natural match for older Upper East Side apartments.

So the two decisions are separate: pick the core for weight and sound (hollow vs solid), and pick the style for looks (flush vs panel).

Which Door Should You Choose? A Quick Guide

• Closet or pantry, tight budget: hollow core flush.
• Bedroom or bath, want quiet and privacy: solid core.
• Prewar or brownstone character: panel door, solid core if you want it to feel period-correct.
• Painting it a bold color: a primed flush or panel door takes paint beautifully. See our note on paint below.

Sizes, and Cutting to Fit

Interior doors come in standard widths, and older NYC apartments almost never have standard openings. The good news: we cut lumber and trim doors to size in the shop, so a door that is slightly too tall or wide can be fitted to your frame instead of sending you back to square one. Bring your opening measurements and we will help you get it right.

Interior Door FAQs

What is the difference between hollow core and solid core doors?

A hollow core door is light and affordable with a honeycomb interior. A solid core door has a dense engineered core, so it is heavier, quieter, and feels more substantial. Choose solid core when you want soundproofing and privacy, hollow core when budget and easy installation matter most.

Are panel doors solid or hollow?

Either. Panel and flush describe the look of the door face, not the core. You can get a panel door in hollow core or solid core, so pick the style for looks and the core for weight and sound separately.

Can you cut a door to fit my old NYC apartment opening?

Yes. We trim doors to size in the shop, which is common for prewar buildings that rarely have standard openings. Bring your measurements and we will fit it.

Can you deliver a door in Manhattan?

Yes, we offer same-day delivery across Manhattan, so you do not have to carry a bulky door home yourself.
