Oak Solid Core Flush Door

A flat oak face over a dense core. The upgrade that is felt rather than seen: heavier in the hand, quieter through the wall, and it takes ironmongery anywhere on the edge.

Delivery & returns
Delivery
Quoted, not published. This leaf alone is about 29.7 kg, so the cost depends on how many you order and where they go. Add your postcode with the list and it comes back priced.
Returns
Set out in the returns policy. Check the size against the door you are replacing before you trim, paint or hang anything — a cut leaf cannot go back as new.

Everything else — construction, thickness, fitting — is the detail below.

The detail

Description

Visually identical to the standard-core oak flush door, and a different object to live with. Specify it on a study, a bathroom, or a bedroom off a landing that gets used late. It needs three hinges and a lining fixed properly back to the structure.

A flat oak face over a dense core. The upgrade that is felt rather than seen: heavier in the hand, quieter through the wall, and it takes ironmongery anywhere on the edge.

Weight is estimated from the leaf size and thickness, not measured — it is accurate enough to work out hinges and whether you can carry it upstairs, and we confirm the real figure from the supplier before anything is freighted.[VERIFY: supplier spec]

Rows marked [VERIFY: supplier spec] are ones we have not yet confirmed with the manufacturer. We would rather show you that than a plausible number: trimming allowance and core type are the two figures that ruin a door if they are wrong, so we ask the supplier and come back with the answer. Work out what you need to take off once you have the allowance.

Delivery & returns

Delivery

Contact us for delivery. Doors are heavy and awkward — this leaf alone is around 29.7 kg — so what it costs and how it arrives depends on how many you order and where you are. We would rather quote it properly than print a number that turns out to be wrong.

Add the door to your list with your postcode and we will come back with the delivery cost as part of the quote.

Returns

Your cancellation and return rights are set out in our returns policy.

Practical advice either way: check the size against the door you are replacing before you trim, paint or hang anything. Once a leaf has been cut it cannot go back to the supplier as new.

Build note — not customer copy: the returns and cancellation wording itself is regulated (Consumer Contracts Regulations 2013, Consumer Rights Act 2015) and must be written or approved by the owner's solicitor before launch. Nothing on this page states a policy on their behalf.[NEEDS HUMAN SIGN-OFF]

Questions people ask

What size door do I need?

Measure the door you are replacing, not the opening — the leaf is what we supply and it is sized to sit inside the lining with a gap all round. This one comes in 7 sizes: 4 imperial and 3 metric. If none of them matches what you took off the wall, send us the measurements before you order anything — an opening that fits nothing standard usually means the lining has been altered.

Is this door available in metric sizes?

Yes. Alongside the imperial sizes there are 3 metric sizes — 2040mm tall and 40mm thick, which is the family used in most newer houses. Both sets are listed on this page with their millimetre dimensions, because the UK trade quotes imperial but supplies in millimetres.

Does the price include a frame, hinges or a handle?

No. The price is for the door leaf on its own, which is how doors are sold across the trade — but it is also why door orders go wrong. Hanging it needs a lining or frame, hinges, a latch and a handle. They are listed on this page under "What you also need" so you can see the real cost of the job before you commit to any of it.

Can I trim it to fit?

Usually a small amount off each edge, but how much depends on how the door is built — a lighter door has a narrower solid lipping to cut into than a solid one. We confirm the trim allowance for this specific door before you order rather than guess at it here.

What finish does it arrive in?

Whichever you choose above — unfinished, oiled or lacquered. Unfinished means bare timber: it needs oiling or lacquering after it is hung, which is the right choice if you are matching existing joinery. Ready-finished costs more and saves you the job.

How much is delivery?

We do not publish a delivery price yet, because we would rather quote it than guess it. Doors are heavy and awkward, and what it costs depends on how many you order and where they are going. Add the door to your list with your postcode and the delivery cost comes back as part of the quote.

What you also need

This page sells the door leaf. Hanging it takes three or four other things, and the usual reason a door order goes wrong is that nobody mentioned them.

Not sure which of these you need? Add the door to your list and say what the opening looks like — we will tell you what is missing before you spend anything.
