Solid Oak Internal Doors
A solid oak door is made from oak all the way through, so the grain runs right to the edges and the door can be sanded back and re-oiled over its life. Our solid oak internal doors carry the natural grain and warmth of oak through the home, and they sit just as well in a period property as in a modern one. They are part of our wider range of solid oak doors, and you can see the full choice of oak internal doors in every material on our main oak doors page. This page gathers our solid oak internal doors in one place, so you can compare every style, character and finish before you choose.
Solid oak or oak veneer
Every door here is solid oak, but it helps to know how that compares with a veneer. A solid oak door is oak throughout, so it can be trimmed to fit and refinished again and again, and the grain carries across the whole face and the edges. An oak veneer door sets an oak face over an engineered core, which stays flatter where a door meets more changes in warmth and damp. Solid oak is the choice when you want the full depth of the wood, while a veneer core suits a spot where staying flat matters most. Both show an oak face; the difference is whether the oak runs all the way through.
Prefinished or unfinished
Solid oak doors come either prefinished or unfinished, and this decides how much work you do on site. Our prefinished doors arrive with the oak already sealed and ready to hang, so the faces need no oiling before they go up. Our unfinished doors are supplied bare, which lets you set the exact colour and sheen yourself once they are hung. Choose prefinished for speed and a consistent factory finish, or unfinished for full control over the final look. Either way, any edge you trim or cut-out you make should be sealed as you fit the door, so the whole door stays protected.
Oak characters to choose from
Solid oak comes in more than one character, so you can set the look as well as the build. Our rustic grade keeps the knots and natural movement for a warmer, lived-in feel, while American white oak reads cleaner and more even. If you want a paler tone than solid oak offers, our light oak doors hold a soft, bright colour, though these are oak veneer rather than solid. Our European oak doors carry a warmer, more figured grain, and our Grade A solid oak doors are cut from the top selection grade. You can compare every material, finish and character side by side on our internal doors by material and finish page. That makes it easy to settle on the solid oak interior doors that suit your home before you choose a style.
Finishing and caring for solid oak doors
We recommend finishing solid oak with a clear hardwax oil such as Treatex, which soaks into the wood and leaves a natural, low-sheen finish that is easy to patch and repair. Treatex also make coloured hardwax oils, so you can tone the oak and still keep that natural, oiled finish. Give the door a light sand, remove the dust, and apply two thin coats, sealing every face and edge including the top and bottom. Avoid Danish oil, varnish and lacquer, as these do not protect the door in the same way and can void the guarantee. To keep them looking their best, dust them regularly and re-oil from time to time, dealing with any marks early. You can find the oils we recommend on our finishing products page, and finish the job with matching door hardware.
Solid Oak Door FAQs
Dust them regularly with a dry, soft cloth, and wipe spills quickly so they do not mark. Re-oil the door from time to time with a hardwax oil such as Treatex to keep it protected. Avoid harsh or abrasive cleaners, which can damage the finish.
Most solid oak doors allow a small trimming allowance, usually up to around 10mm off each edge, though it varies by door. Check the size guide on the product before you trim, and seal any cut edge with oil as you fit.
No. Bare oak takes up moisture, which can cause it to move, so finish the door fairly soon after it is hung. A clear hardwax oil such as Treatex protects the wood and brings out the grain. Avoid Danish oil, varnish and lacquer, which do not protect the oak as well and can void the guarantee.
