They can be created from a red oak or a white oak that have various characteristics. Our Oak Internal Doors are made from a semi-solid core and use an oak veneer finish.

Using solid core construction means doors won’t warp or crack in the way that traditional solid Oak Internal Doors can. With the desire for contemporary flush finish doors, this cannot be easily achieved with one piece of solid wood.

Solid core oak veneer internal doors look fantastic and identical to a solid oak internal door without the risk of warping. The quality of veneer and finish achieved means your investment will look and function for many years to come.


We can make bespoke made-to-measure Internal Oak Doors so that you can get one to fit your exact measurements. This is if you have a slightly smaller or larger door frame.

If this is a requirement, please see the product specification on the particular oak door you were wanting. This is to see if this bespoke measurement is possible.

What is a pre-finished oak door?

When you see a door described as pre-finished, it means the door itself is ready to install. A pre-finished Oak Internal Door would be one that does not need to be stained or primed. 

What are oak veneer doors?

Oak veneer is essentially an oak door made from thin slices of oak placed on top of a lower oak density core. This helps preserve high-quality woods without skipping the quality of the door.

Can you paint oak veneer doors?

An excellent attribute of Oak Veneer Doors is that they can be treated like any other wood. This means you can stain, prime and paint veneer wood like you would with any other door. Internal Oak Veneer Door is a good investment because you get the aesthetic appeal of a normal solid wood door without the additional expenses and weight.
