Unfinished Internal Doors

At Climadoor, every unfinished internal door is built to last. Our heavyweight engineered solid core construction provides strength, stability, and excellent thermal efficiency, while generous lippings make trimming simple. This is perfect for older properties where openings may not be perfectly square. Just like our primed and pre finished doors, they're FSC Mix certified, meaning they’re made with at least 70% responsibly sourced material.

We offer unfinished doors in a wide range of sizes and styles, including traditional panel designs, contemporary flush styles, glazed models with clear or frosted glass, and charming cottage-inspired looks. Fire-rated options are also available for added peace of mind.

Oak Unfinished Internal Doors

Our internal oak doors are crafted from premium FSC Mix certified materials with a robust solid core. They're topped with an unfinished oak veneer, allowing you to add your preferred stain or varnish. The natural beauty of the wood grain patterns bring character to any space, whether you’re aiming for a modern interior or something more classic.

With an unfinished surface, you can choose a clear lacquer to highlight the beauty of the timber or apply a stain to achieve a deeper, richer finish. These oak internal doors are designed for durability, resisting daily wear while retaining their refined appearance. Generous lippings make them easy to trim to size for an exact fit, even in older properties.

Available in classic panel designs, contemporary styles, and glazed versions with clear or frosted glass, our oak range also includes FD30 fire-rated options for both safety and style.

Pine Unfinished Internal Doors

Our pine unfinished internal doors are a versatile, cost-effective choice that doesn’t sacrifice quality. Their pale colour and soft, even grain make them perfect for painting or staining, whether you’re aiming for a bright modern look or a rich traditional shade.

Built with a solid core for strength and stability, these doors are also FSC Mix certified, supporting sustainable forestry. The generous lippings allow for precise adjustments, ensuring a perfect fit in any doorway.

Pine unfinished doors are available in a variety of designs, from traditional and contemporary to rustic cottage styles. Glazed versions with toughened safety glass provide the option to let natural light flow between rooms while maintaining privacy where needed.

Styles to Suit Any Home

The collection spans a wide variety of designs, from classic panel doors to glazed styles with clear or frosted safety glass. Choose traditional or cottage-inspired patterns for a timeless look, or opt for contemporary flush and minimalist designs for modern interiors. With such a broad range of widths and heights available, finding the right fit is straightforward.

Benefits of Choosing Unfinished

Opting for an unfinished internal door brings several advantages:

• Lower initial cost compared to prefinished options.
• Complete control over colour and sheen.
• Perfect matching to other timber features in your home.
• Flexibility to apply specialist finishes such as oils, stains, or paints.

Because these doors arrive untreated, you can apply your chosen finish on-site, ensuring the result looks exactly as you want it. This is especially useful if you’re working on a larger renovation where matching tones is important.

If you decide unfinished options aren't for you, don't forget to visit our fully finished internal doors and primed interior doors sections. You'll find the right finish for your project, whether you're looking for convenience or customisation.

Sustainability as Standard

All Climadoor unfinished doors carry FSC Mix certification, meaning at least 70% of the timber comes from FSC-certified forests, recycled sources, or controlled wood from responsibly managed forests. You can buy with confidence knowing your choice supports sustainable forestry practices.
