Replacing the doors or a new kitchen: which makes sense?

10 September 2026 · The Home Upgrade Co.

A lot of people ask for a new kitchen when what they want is for the kitchen to look new. Those are different jobs with very different costs, and which one you need is decided by the boxes behind the doors, not by the doors.

What does replacing just the doors actually change?

The look, and little else. New doors and a worktop change what you see, while the layout, carcasses and storage stay exactly as they are.

That is not a criticism. If the layout works and the boxes are sound, changing what you see is the efficient answer and a full rip out would be waste.

What it will not do is give you more storage, move the sink, fix a bad layout or make a cramped kitchen work better.

When is a door swap the right call?

When the layout already works, the carcasses are solid, the hinges and runners are sound, and your complaint about the kitchen is genuinely how it looks.

Kitchens from the last fifteen years or so are often built on carcasses that have plenty of life left, with doors and a worktop that have taken all the wear.

If you find yourself saying the kitchen is fine but tired, that is usually a doors and worktop job rather than a new kitchen.

When does replacing the doors not make sense?

When the layout is the problem. New doors on a kitchen with nowhere to put anything leave you with the same kitchen, looking newer.

It also stops making sense once several carcasses are swollen, sagging or blown at the base, which is common where there has been a slow leak under a sink.

That is a chipboard failure, and it is the reason we publish the board our own carcasses are built on. Ours are 18mm melamine faced plywood, faced both sides and E1 rated, set out in full on our kitchen units and cabinets page.

And it rarely stacks up if you are doing anything structural anyway. If a wall is coming out, design the kitchen for the room you will actually have.

Do new doors fit old carcasses?

Only if the hole spacing and hinge type match, which is not guaranteed across brands. This is the detail that catches people out on a door swap.

Carcasses from the big flat pack systems and from Irish trade suppliers do not share one standard, so replacement doors have to be made to your specific boxes.

That is doable, but it means the doors are made to measure rather than bought off a shelf, which narrows the saving people expect.

How do you tell if your carcasses are sound?

Look at the base of the unit under the sink, then push down on a shelf. Swelling, sagging and soft chipboard are what to look for.

Check the runners too. If drawers drop or catch, that is often the hardware rather than the box and can be dealt with either way.

If more than a couple of units are gone, the case for keeping them weakens quickly, because you are then paying to work around boxes you do not trust.

What about the worktop?

The worktop is usually replaced either way. It takes the most wear, and lifting it is what lets anything underneath be inspected or replaced properly.

What decides the worktop cost is the material rather than the length. Our quartz versus granite and quartz versus laminate guides cover that choice.

If you are replacing the worktop anyway, price both routes at the same time, because a good part of the disruption is shared between them.

Which should you do?

If the layout works and the boxes are sound, replace the doors and worktop. If the layout is wrong or the carcasses are going, fit a new kitchen.

Put plainly: doors fix appearance, a new kitchen fixes how the room works. Deciding which problem you actually have is most of the decision.

It is worth being honest with yourself here, because a door swap on a kitchen you dislike using tends to be money spent twice.

What we do

We design and fit new kitchens. If a door and worktop swap is genuinely the right answer for your room, we will say so from your photos.

Our free 3D design draws the room from your photos, video and sizes, and the itemised quote shows what each part costs so you can see where the money goes.

Every kitchen is priced individually from its own design, but you should not have to wait for a number to know whether we are in your range. Ours start at EUR 12,000 fitted including VAT, and a typical family kitchen with quartz worktops runs EUR 15,000 to 25,000. Plans and quote from your photos, video and sizes, and twelve weeks from sign-off to fitted. See our kitchens page.

Every kitchen we fit is premium and made to the highest spec: made to measure on a melamine faced 18mm plywood carcass, not chipboard, and fitted by our own team. It is priced to that standard. Quality at this level is not a budget purchase, and if you are working to a tight budget, we are honestly not the right fit.

Frequently asked questions

Is replacing kitchen doors cheaper than a new kitchen?

Considerably, because the carcasses, the plumbing and the electrics all stay put. The saving narrows if the doors have to be made to match unusual boxes.

Can you replace kitchen doors and keep the worktop?

You can, but most people change both together. The worktop takes the most visible wear, and new doors against a worn worktop tend to show it up.

How do I know if my kitchen carcasses are still good?

Look under the sink for swelling at the base, press down on shelves for sag, and check whether drawers still run straight. Those three tell you most of it.

Do you replace kitchen doors as a service?

We design and fit full kitchens. If a door swap is the better answer for your room we will tell you from your photos rather than quote you for more.
