Flush Doors Manufacturer | Factory-Direct Interior Flush Doors for Builders

Flush doors have a completely flat face with no raised or recessed panel lines — the opposite of a paneled door like a shaker or 6-panel style. The flat face can be left plain or given simple surface grooving. Both our Molded Doors and Veneer Doors lines can be built in this flush style.

What Is a Flush Door?

A flush door features a continuous, flat face without the traditional raised or recessed panel structure. It offers a clean, streamlined appearance that works well across a range of interior styles, from modern and minimalist to more traditional spaces.

One of the most common points of confusion is that flush is not a material or a specific door construction method. It describes the appearance of the door face. A flush door can have a completely plain, flat surface with no decoration, or it can incorporate grooves, routed lines, carved details, or other decorative treatments while maintaining an overall flat-face appearance.

Depending on a builder’s requirements for materials, finishes, and performance, flush doors can be constructed in different ways.

Our product range primarily includes Molded Flush Doors and Veneer Flush Doors.

Shaker Door Panel Styles & Configurations

Molded Flush Door

Our Molded Doors can be made in a flush door style, using a 3mm MDF skin pressed into a flat, continuous surface without the traditional panel design. The doors ship primed and paint-ready, so the final finish can be applied on site or at a paint shop — the standard choice when a project specification calls for a uniform color across multiple units.

See our full Molded Doors page for hollow-core or solid-core options and configuration details, which also apply to the flush version.

Veneer Flush Door

Among interior doors, a Veneer door can also be made in a flush door style. It uses a 5mm MDF skin finished at the factory with PVC vacuum thermofoil or melamine, creating a wood-look grain finish. No painting is required — the door arrives factory-finished. If a project needs the look of a flush door while also wanting the appearance of wood without using solid wood, this is a suitable option. See our Veneer door page for details.

Molded Flush Door Veneer Flush Door
Skin thickness 3mm MDF 5mm MDF
Surface finish Primed, paint-ready PVC thermofoil or melamine, including wood-grain finishes
Paint required Yes — finish decided on site or at the paint shop No — pre-finished at the factory
Core options Hollow or solid Hollow or solid
Surface grooving / carved detail Available Available
Best for Projects needing a uniform painted color across many units, or a lower-cost paint-grade option Projects that want a finished door with no separate paint step, including a wood-grain look without solid wood

Both constructions accept the same optional detail: light surface grooving or a simple carved line across the face, if a project wants a hint of texture without breaking from the flush look. Both also come in hollow-core or solid-core — the same trade-off as the rest of our interior door range.

Flush vs. Panel Doors — and Where It Gets Confusing

What does "door flush" mean? It describes a door face with no raised or recessed panel detail — completely smooth from edge to edge, as opposed to a paneled door where the frame and panel sit at different depths.

Flush door vs. panel door — what's the difference?

A panel door (like our Shaker Doors or Molded Doors in a panel profile) has a visible frame around one or more recessed or raised panels. A flush door has none of that — one continuous flat face. Both can be built from the same underlying materials; the difference is purely the face design.

Flush door vs. solid door — are they the same thing?

Not quite. "Solid" usually refers to the door's core (solid-core vs. hollow-core), while "flush" refers to the face design. A flush door can be built with either a hollow or solid core — the terms describe two different things and aren't interchangeable.

Flush Interior Doors: Configurations & Applications

Flush is a face style, not a fixed door type — it works across several different configurations, and which one gets specified usually comes down to the overall architectural style of the project rather than the flush face itself.

Door Configurations

Single swing

The standard configuration for most interior openings.

Double doors

Two flush slabs paired for wider openings, such as a primary suite or a formal room entry.

Bifold

Flush bifold doors sized to standard closet openings, for a seamless look that doesn't compete visually with paneled doors elsewhere in the same room.

Sliding / pocket

Flush faces are a common choice for sliding and pocket doors, since there's no panel detail to interrupt the door as it moves along the track.

Space Applications

Flush interior doors can be used throughout residential and commercial interiors, including bedrooms, closets, home offices, hallways, and other interior spaces. Rather than being limited to a specific room, the choice of a flush door is often driven by the overall architectural and interior design style. Its clean, flat appearance works particularly well with modern, contemporary, minimalist, and transitional interiors, while different finishes and surface details can help it fit into a wider range of design schemes.

Flush Door Sizes & Dimensions

Flush doors follow the same standard sizing as the rest of our interior door range — no separate size chart needed. The most common flush door size is 30" × 80", with taller options (84", 96") available for higher-ceiling or higher-end projects. For the full width/height chart and rough opening guidance, see Standard Interior Door Sizes, Widths & Specifications

Flush Door Manufacturer — Specs & Ordering

We manufacture flush doors directly — as a flush door manufacturer and supplier working with builders, contractors, and door retailers across the US, not a reseller of someone else's stock.

Since flush is a face style rather than a standalone product line, most customization options depend on which underlying door type you choose: see the Molded Doors or Veneer Door customization options for construction-specific choices like finish, panel-skin material, and program terms. Beyond that, a few options are available on any flush door regardless of construction — surface grooving or carved detail, and hollow or solid core.

Assembly formats: Slab, Knock-Down (KD), Semi-Prehung, and Prehung.

Flush Door FAQ

Everything Builders Need to Know Before Purchasing

A flush door has a completely flat face with no raised or recessed panel lines, unlike paneled styles such as shaker or 6-panel doors. We build flush doors two ways: a molded 3mm MDF skin (primed, paint-ready) or a pre-finished 5mm veneer skin in PVC or melamine, including wood-grain finishes.
