Internal Flush Door Faces

Our internal flush doors come in pre-finished and unfinished options, allowing you to choose a ready-to-install solution or customise your finish. We also offer interior door frames and external flush doors for added strength and a consistent look throughout your home. Our interior flush doors come with the following finishes: 

• Laminated: Durable, pre-finished doors wrapped in hardwood laminate film. These doors are easy to clean and maintain, though best kept out of prolonged direct sunlight.

• Painted: Pre-finished doors, professionally prepared and ready for installation.

• White-Primed: Supplied with a white undercoat, ensuring your topcoat’s colour is bright and vibrant.

• Primed: Coated in a high-performance primer, creating a smooth, sealed surface that's ready for your chosen topcoat.

• Walnut Veneer: A sophisticated, dark veneer with striking grain detail. Walnut veneers are sustainable, cost-effective and sturdy.

• Oak Veneer: Durable bases and edges with a rich grain. May require more maintenance and staining.

Flush Internal Door Styles

Whether your home leans modern or cottage-inspired, our wide selection of flush door styles ensures there’s an option to match your interior design. 

• Modern: Clean, crisp and new-age. Popular styles include White-Primed Dover, Oak Carini and Panelled Vancouver.

• Cottage: With warmer textures and panelled designs. We recommend our Textured Mexicano, Cheshire Veldor and Oak Belize doors for a cottage-inspired home.

Flush Interior Door Construction

Flush internal doors are highly versatile thanks to their simplistic design. This makes them suitable for homes, offices and commercial spaces. Each property has its own requirements, which is why we offer flush internal doors with a range of core constructions, including:

• Solid Core: High-quality solid core doors that are durable, secure and heavier, typically requiring at least three hinges and a sturdy door frame.

• Semi-Solid Core: Made from a mixture of solid and hollow parts, this offers additional security and weight while still allowing for easy opening.

• Hollow Core: Lightweight internal framework, combined with a honeycomb construction. These doors are easy to handle and are ideal for many residential homes. 

Internal Flush Fire Doors

Our flush fire door models offer a mix of aesthetics and essential safety. Built to support fire compartmentation, they help slow the spread of fire and smoke, allowing more time for safe evacuation.

Available in panelled and glazed designs, our fire doors comply with UK fire safety regulations.

FAQs on Flush Interior Doors

Here are a few common questions about our flush doors for sale. If you have any more questions about delivery times or door styles, don’t hesitate to contact our team.

Are interior flush doors easy to install?

Yes, due to their simplistic design, flush interior doors are offered in a range of sizes and weights. You can find a pre-finished door that suits your door frame perfectly. This will allow for a seamless and easy installation.

If you’re inexperienced with door installations, we recommend you hire a registered installer for a clean finish and less hassle. Direct Doors does not offer installation services, but we do supply door fittings, hinges and flush pull handle packs for your ease and convenience.

Do flush internal doors come with glass fittings?

No, most flush doors offer a flat surface, making them versatile and a common staple in most UK homes. Some designs feature subtle decorative panel detailing. If you’re looking for doors that offer better flow and more natural light, consider browsing through our interior doors with glass.
