Oak Internal Doors

Pre-finished or unfinished: choosing oak internal doors

Pre-finished suits most buyers, as the door goes up once it’s trimmed. Unfinished suits anyone matching existing joinery, or happy to spend a weekend with a brush to save on the price.

The factory finish seals the timber evenly, so there’s no drying time between coats on site. If you trim a pre-finished door, reseal the cut edges with a clear finish before hanging it. Our pre-finished internal doors include every oak design that arrives ready to go up.

Most LPD oak and Deanta oak designs arrive pre-finished, and some are also sold unfinished, so check the finish options once you’ve chosen a style.

Unfinished oak internal doors are bare veneer, which means you control the final colour. Browse our unfinished doors if you’d like to match an oiled floor or a lacquered staircase.

Oak veneer or solid oak: what you’re buying

Our oak veneer doors have a thin layer of real oak bonded to a solid engineered core. Deanta uses North American white oak veneer, and LPD lists its faces as white oak veneer.

Plenty of buyers set out looking for solid oak internal doors, but a veneered door is far less prone to warping and splitting than solid timber, and it costs less. The grain and colour you see are still real oak, so expect the figure and shade to vary a little from one door to the next.

One exception: an LPD Vancouver design uses an oak-grain laminate instead, so check the product title if you specifically want oak veneer internal doors.

Oak internal door styles

Our interior oak doors cover most of the looks you’d find in a British home.

• Shaker: flat panels set in a square frame. LPD’s oak Shaker doors come pre-finished or unfinished, and as a bifold.
• Panelled: from the 3-panel Idaho and 4-panel Regency and London to the 7-panel Carini with raised mouldings.
• Vertical grooved: the Mexicano, Belize and Melbourne ranges, with long grooves for a cottage feel.
• 1930s style: the LPD DX 30s, styled on doors of that era.
• Flush and pattern: the plain LPD Flush and the grooved Pattern 10 and Pattern 20.

As a rough guide, Shaker and flush designs suit modern homes, panelled doors sit well in Victorian and Edwardian houses, and grooved designs give a softer, rural look.

For wider openings there are oak bifolds, pairs such as the Coventry and Lincoln, and Lincoln and Reims room dividers.

Internal oak doors with glass

Glazed oak internal doors let light from a bright room into a dark hallway or landing. Our oak designs come in clear, clear bevelled, frosted-line and brilliant-cut glass, from the half-light Mexicano and Deanta Ely to the Lincoln 3L and Vancouver 4L. Clear glass gives the most light; frosted-line and brilliant-cut patterns add a little privacy. Compare them all in our glazed internal doors.

Light, white and smoked oak internal doors

Several LPD designs are listed as white oak internal doors, meaning the veneer is cut from white oak; they’re still oak-coloured, not painted. If you want an actual white door, our white primed doors are ready for paint.

For light oak internal doors, the LPD Mexicano Blonde Oak is the palest finish we stock, while Deanta’s Natural Oak range keeps the timber close to its raw tone.

At the darker end, LPD’s smoked oak Vancouver and Regency have a deeper, browner tone. If you’d like darker still, our walnut doors are the next step.

Match the tone to what’s already in the room: a pale floor suits blonde or natural oak, while a darker floor sits better with smoked oak.

Still wondering whether a painted door would suit the room better? Our oak vs white internal doors comparison sets the two side by side.

Fitting and caring for oak internal doors

Let an internal oak door acclimatise in the room for a few days before you hang it, stored flat and away from fresh plaster.

Natural oak can mellow slightly with daylight over the years, so doors in a sunny room may deepen a shade. Clean with a damp cloth and avoid household sprays that leave a film. In bathrooms and en suites, make sure every face is well sealed and the room is ventilated, because steam and damp can make any timber door swell. For general finishing advice, our guide to unfinished, primed and pre-finished doors covers the basics.

Imperial sizes are 35mm thick and metric sizes 40mm, so measure the frame opening to find out which system your house uses. If the old frame is past its best, order matching oak door frames and linings at the same time. Solid-core doors are heavy, so hang each one on three hinges.

Before you order, note the height, width and thickness using our measuring guide.

Oak internal doors: common questions

How much do oak internal doors cost?

Prices for internal oak doors depend on the style, the glass, the size and whether the door is pre-finished. Unfinished doors cost the least, and glazed or pre-finished designs more. We sell oak internal doors UK-wide, and you’ll find the price of each size on its product page.

Are these solid oak or oak veneer?

Oak veneer on a solid engineered core, which keeps the door stable and the price down.

How do I finish an unfinished oak door?

Lightly sand, then brush on a door oil or a clear lacquer in several thin coats. Seal the top and bottom edges as well as the faces and sides before hanging, so the door takes up moisture evenly. Avoid wire wool between coats, as it reacts with the tannin in oak and leaves dark marks.

Which brand makes the best oak internal doors?

Neither is better across the board, so start with the design you like. Deanta offers FSC-certified supply and a 10-year warranty. LPD, based in Leeds, has the wider choice of styles, including Shaker, DX 30s, bifolds and room dividers. Between them they make all the oak doors we sell.

Pre-finished or unfinished oak: which should I buy?

For a rental or a whole-house refit, pre-finished, as every door arrives the same colour. In a home that already has oak floors or stairs, unfinished lets you pick an oil or lacquer that matches them.

Can I trim pre-finished oak internal doors?

Yes, within the allowance for that design. Score the cut line first so the veneer doesn’t splinter, then reseal the cut edge before hanging.

Can I get an oak fire door?

Yes, from a separate range. None of the oak internal doors here carries a fire rating, so where an opening needs FD30, choose one of our oak fire doors instead.
