Unfinished doors, as the name suggests, are doors that come without any pre-applied paint, stain or protective finish. They’re essentially a blank canvas — ready for you to customise however you like. Whether that’s bringing out the natural grain of the wood or tapping into the latest paint trends. Ideal for perfectly complementing your home’s colour scheme.

Why Choose Unfinished Doors?

The primary appeal of unfinished internal doors lies in their versatility and the ability to achieve a truly bespoke look. Perhaps you want a perfect match with other furnishings — or you simply want to add style points with a unique or unexpected colour option.

Customisation
This is the biggest draw. You have complete control over the final appearance of your doors. Whether you envision a vibrant pop of colour, a rich wood stain to highlight natural grain, or a subtle, natural oil finish, the choice is entirely yours.

Cost-effective
Often, unfinished doors are more budget-friendly than their prefinished counterparts. While you’ll need to factor in the cost of finishes and your time, the initial purchase price can be lower. This can work well if you’re doing a one-off self build or gradual renovation project.

Matching Existing Decor
If you’re trying to seamlessly integrate new doors with existing woodwork, skirting boards, or architraves, an unfinished door allows you to achieve an exact colour match, something that can be challenging with pre-finished options.

Quality Control
Finishing the doors yourself allows you to oversee the application of your chosen product. This means you can pay close attention to details that might be overlooked in a factory setting and achieve the look and finish that you personally want.

Unique Style
You’re not limited to the standard finishes offered by manufacturers. Experiment with different techniques (think: colour drenching, distressed effects or stencilled designs) to create one-of-a-kind statement doors that reflect your design vision.

Painting Unfinished Internal Doors

Painting is perhaps the most popular option for unfinished doors — ideal for cultivating character in a new home or giving an older property a quick, easy and trend-led update. There’s a world of colour to choose from and it’s practical too.

Need to cover imperfections or want a smooth uniform finish? Painted unfinished doors are the solution. Just be conscious that this finish can hide the natural wood grain and requires careful preparation. And if you’re opting for a hand-stencilled motif, you’ll need to carve out a good few hours.

Bonus tip: Always apply a good quality wood primer. This seals the wood, provides a uniform base for the paint, and improves adhesion. Allow it to dry completely as per manufacturer instructions.

Staining Unfinished Doors

If you prefer an organic modern interior design look or want to introduce rustic textures and natural tones, stained wood internal doors might be the best option. Staining enhances the natural beauty of the wood, allowing the grain to show through while adding depth of colour. If you’ve opted for high quality solid wood doors, you’ll definitely want to make this woodgrain a feature and potentially match it other wooden elements in your home.

Oiling Unfinished Doors

Oil finished internal doors are easy to look after and can be more eco-friendly depending on the product used. Oil penetrates the wood, nourishing it from within. This creates a natural, matte look that will be slightly darker than how the wood was originally. It’s more subtle than staining — ideal for minimalist or Scandinavian style interiors. And while oiling internal doors does mean you’ll have to reapply it over time, it’s great for preserving natural colours.

Varnishing Internal Doors

Varnish is a more durable alternative to door oil. It creates a protective layer on the surface of the wood, offering excellent resistance to wear and tear, moisture and UV light. It’s available in various sheens from matte to high gloss. Use varnish for doors to protect them from water (think: kitchens, utility rooms, bathrooms and boot rooms). It can look slightly less natural than oil but is more long-lasting. Keep an eye out for chips or scratches to keep the glossy finish.

How to Prepare Internal Doors for Finising

Achieving a professional-looking finish on your unfinished doors requires patience and attention to detail. Take your time and don’t skip steps. Preparation is key — clean doors before finishing and research the best priming products and methods for your chosen finish.

First, allow the doors to acclimatise to the room’s temperature and humidity for a few days before starting. Ensure the doors are free from dust, dirt or grease. A damp cloth followed by a dry one usually does the trick.

Next, lightly sand the door in the direction of the grain using fine-grit sandpaper (180-220 grit). This smooths the surface and helps the finish adhere. Finally, thoroughly remove all sanding dust with a vacuum cleaner and a tack cloth. This is crucial and ensures a perfect finish.

Paint Colour Trends for 2026

Staying ahead of interior design trends can inject new life into your home. Here are some trending paint colours expected to be popular next year — all you need now is the best unfinished doors to be your backdrop.

Earthy Greens
From deep forest greens to muted sage and olive tones, these colours bring a sense of nature and tranquility indoors. They pair beautifully with natural wood accents and warm neutrals.

Warm Neutrals
Expect to see a rise in creamy beiges, soft greiges (a mix of grey and beige) and subtle mushroom tones. These provide a comforting and sophisticated backdrop.

Deep Blues
Rich, inky blues and sophisticated navy continue to be strong contenders, offering a hint of drama and elegance. They work particularly well in studies, bedrooms and dining rooms.

Dusty Pinks and Terracotta
For those seeking a softer, more inviting palette, muted pinks with a hint of grey and warm, earthy terracotta shades will be popular — especially in more eclectic or bohemian interiors which began trending again this year.

Charcoal and Black
For a bold, modern statement, dark charcoal and true black doors are becoming increasingly popular. They create strong contrasts and add a contemporary edge. Pair them with light walls for extra dramatic effect.

Soft Greys with Warm Undertones
While cool greys are fading, warmer greys with subtle yellow or brown undertones will continue to be a versatile and popular choice, offering a sophisticated yet welcoming feel.
