Custom Kitchen Cabinets Guide: How the Build Gets Decided

Three decisions, not one, and each is made in a different place

Custom kitchen cabinets is one of those phrases that everyone agrees with and almost nobody defines. Ask five suppliers what makes their cabinets custom and you will get five answers, because the word is doing three jobs at once. It can mean the carcase is cut to the room instead of to a catalogue. It can mean the inside is organised around what you own. It can mean the front is a finish nobody had on a shelf. Only when you separate those three does the price of a quotation start to make sense.

This guide is built the way we build a kitchen: from the room inward, and from the drawing outward. First what "custom" covers, then the four things that have to be measured or scheduled before a single panel is cut. Then the sizes that can move and the ones that should not, then the body, the fronts and the hardware, and finally the quotation itself. Nothing here is a mood board. It is the sequence an order actually follows.

One thing worth saying at the start, because it changes how you read everything below. A stainless cabinet is not a standard box that has been enlarged. It is cut, grooved and folded sheet, which means an irregular wall is a drawing problem instead of a manufacturing obstacle. This is the whole reason custom work is the normal case here instead of the exception.

What custom kitchen cabinets actually are

Strip the marketing away and custom work is whatever the factory has to decide per order that a catalogue cannot decide for you. In a stainless kitchen there are exactly three such layers, and they differ in how expensive they are to get wrong.

The first is the carcase. A run of wall, a tall block, an island and a corner are cut to the real dimensions of your room, which on a survey rarely match the plan. A wall that is 3,412 mm long is not a wall that takes two 1,700 mm cabinets; it takes a drawing. Columns, waste pipes, boiler flues and sloped ceilings are resolved in the same drawing, usually by folding the panel around the obstruction instead of by adding a filler strip in front of it. This is the layer most people mean by custom, and it is the one that has to be right the first time because it cannot be altered once the panels are folded.

The second is the interior. A drawer box has a height, and the height should follow what the drawer will hold. A 200 mm drawer quietly collects nothing but clutter; the same space split into two 100 mm trays takes the lids, the baking sheets and the spice jars that a fixed-height drawer turns into a pile. Tray runs, pull-out larders, a cutlery insert positioned where you actually stand, a bin unit beside the sink instead of somewhere behind you: none of that is a product you can order by name. It is a plan.

The third is the front. Here "custom" is at its thinnest, because a finish is chosen from a range and then applied to panels cut to the sizes the drawing produced. That is not a weakness; it is why a stainless kitchen can be refreshed in years to come. The finish layer sits on top of a structure that does not depend on it, so a change of taste costs a panel set instead of a kitchen.

Read a quotation and you can usually tell which of the three layers a supplier is really offering. A price that changes only when you change the colour is a front price. A price that moves when you change the layout is a carcase price. A price that moves when you change what goes inside the drawers is the only one that covers all three.

Custom kitchen cabinets: what is made to measure, and what is not

The quickest way to see where the custom work sits is to sort the decisions by who fixes them. Some are fixed by the room, some by the drawing, some by a brochure, and one group is fixed by physics and should not be moved at all.

That table explains a question buyers ask constantly: if these cabinets are custom, why is the base depth nearly the same on every project? Because a base depth is not a style choice. It is set by the depth of a worktop, the clearance a standard dishwasher needs and the comfortable reach of an average adult arm. Custom work is not the freedom to ignore those numbers; it is the freedom to resolve everything else around them.

The drawing set that has to exist before anything is cut

A made-to-measure kitchen is decided on paper and merely executed in metal. Four documents carry that decision, and if any one of them is missing the fabricator is guessing on your behalf.

The first is a dimensioned survey. Not a sketch with the overall length on it, but a plan with every wall measured individually, every door and window marked. The ceiling height at both ends of the run, the position of the waste, water and power points, and each obstruction noted with the space it actually takes. A kitchen is usually out of square by a few millimetres across three or four metres, and a drawing that assumes otherwise creates a gap at one end of the run that has to be filled on site.

The second is the appliance schedule. Model numbers, not categories. An oven that was assumed to be 600 mm wide and turns out to be 596 mm is a housing that has to be altered, and the alteration happens to a panel that has already been folded. Ventilation and service clearances come from the same schedule, and so does the appliance column that makes a tall run look drawn instead of assembled.

The third is the storage plan. Go through what you own before the drawers are specified: pan diameters, the tallest pot with its lid on. The trays that never stack neatly, the small appliances that live on the worktop, the bottles that need a shelf instead of a cupboard. A drawer run specified from that list behaves very differently from one specified from a price list.

The fourth is the finish decision, and it is deliberately last. It affects nothing structural, so it should not hold up the drawing, and it is the one item on the list that can be revisited years later without touching the carcase. Suppliers who ask for the colour before the appliance schedule are working backwards.

Custom kitchen cabinet sizes: what can move, and what should not

The useful version of the question is which sizes are worth customising, not whether sizes can be customised. Moving a run length is free in drawing terms and expensive in build terms; moving a worktop height is the reverse. The table below sorts the numbers that come up most.

Two rows deserve a sentence each. The worktop height is the dimension buyers most often want to move and the one most likely to be a bad idea. This is because Raising it to suit a tall cook also raises the underside of the extractor and the reach into a wall cupboard. Where it genuinely needs to change it usually changes by 20 or 30 mm, agreed against the appliance schedule, not by 100 mm for comfort. The drawer heights are the opposite case: almost nobody reduces a tall drawer and almost everybody should, because a drawer specified around the pots you own uses the same box to hold twice as much.

The body a custom cabinet is built around

Custom work at the outside is only as good as the structure it is wrapped around, and in a stainless kitchen that structure is worth naming because most of it is invisible in a photograph.

The material is a 304 food-grade stainless steel body, the grade named part by part. 304 is the 18/8 family, chromium at 18 percent or more and nickel at 8 percent or more. It is the grade used for catering and medical equipment because it tolerates the water, salt and heat a kitchen produces. The gauge is stated instead of assumed: a 0.45 mm body, a 0.6 mm pressed door skin where a profile is formed, and a 0.8 mm natural brushed door where the finish is the metal itself.

Behind the skin is an aluminium honeycomb core bonded under a polyurethane chemical cure at a finished panel thickness of 18 to 25 mm. The core is what makes a thin metal panel behave like a stiff one: the panel comes out about a third lighter than a comparable timber-core door. Roughly 8 kilograms per square metre against 12, and the load that reaches the hinge drops with it. A lighter door is easier on the hardware, and a hinge that is not working hard is a hinge that lasts.

The carcase itself is joined on a mortise-and-tenon assembly, a connection designed to tighten as it is loaded instead of to loosen, with a double back panel behind it. The double panel does two jobs: it stiffens the unit across its span and it stops the wall behind the cabinets acting as a sounding board. Add pre-embedded hardware and the whole assembly stops depending on what happens on site. Inserts sit in the panel from manufacture, a copper-cored insert behind each hinge plate and a six-sided 304 nut at every connector, so the screw gauge matters far less than the socket it is driven into.

The fronts: what a made-to-measure kitchen can be faced with

The front layer is where most of the visible customisation happens, and it is also where the honest answer is smallest: the panel is cut to the drawing, and the finish comes from a range. Knowing which range suits which room matters more than knowing how many exist.

The useful rule is to spend custom money on the carcase and the storage plan, and let the front come from a range. A custom carcase solves a problem in your room and cannot be undone; a custom front solves a problem of taste and can be solved again later. Where a kitchen has a genuine feature elevation, an island that is seen from the living space or a display run that remains the point of the room, the one place a made-to-order front earns its cost.

One practical habit is worth borrowing from the way trade buyers work. Ask for a sample of the exact front and look at it in your own room instead of in showroom lighting. This is because A warm grey that reads cool under display spots can read distinctly warm beside a west-facing window, and a brushed finish changes character again under direct sun. Ordering the sample before the run is released costs almost nothing and it is the only part of the decision that cannot be checked on a drawing.

Hardware, and why the insert matters more than the screw

Almost every complaint about a cabinet that has aged badly traces back to hardware, and almost every hardware failure traces back to how the hardware was attached instead of which brand it is.

A multi-point clip-on hinge rated around 20 kilograms through 100,000 cycles is the working standard here, and that rating is meaningless if the hinge plate is screwed into a panel that was drilled on site. So the plate sits on a pre-set base that goes into the panel during manufacture, and the hinge adjusts from there. The same logic runs through the whole cabinet: a runner chosen for the load the drawer will actually carry, a six-sided 304 nut at every connector instead of a welded one. A copper core in the insert behind the hinge so that the thread that takes the daily load never sees bare, cut metal.

There is a practical consequence worth mentioning because it is the difference between a ten-year kitchen and a lifetime one. When the attachments are pre-set, the fix at year eight is a quarter turn of a screwdriver by whoever is standing there, not a service visit. The hinges and handles guide sets out the ratings in full, and the 304 against 201 comparison explains why the grade under the finish decides whether those fixings ever have to come out.

How a custom kitchen cabinets quotation is built

A made-to-measure price is not a number. It is a sum of decisions, and it becomes readable once you know which lines move. These are the lines that appear on ours, in the order they are decided.

• Cost line: What drives it. Where a buyer can influence it
• Sheet and gauge: The grade named part by part and the body gauge. Only by agreeing the grade honestly instead of by shaving it silently
• Carcase hours: Run length, number of units, obstructions boxed in. In the layout, before the drawing is approved
• Interior fit-out: Drawer count, trays, pull-outs, bin units. Directly, and it is the line with the best daily return
• Front range: Finish, profile, door thickness, custom sizes. By choosing a range instead of a made-to-order face
• Worktop and sink: Whether the sink is welded into the top and how the upstand is formed. By keeping the sink welded instead of dropping in a sealed cut-out
• Hardware: Hinge rating, runner rating, insert system. Rarely worth trimming, because this is the line that ages

Two patterns are worth knowing before the quotation arrives. The first is that the unit rate rarely moves as much as the quantity does: a longer run. More drawers and a wrapped corner all add cost because they add sheet, edge work and factory hours, not because the price per metre changed. The second is that the cheapest line to cut is usually the one that should not be cut. Taking a grade or a runner rating down saves a figure that is small against the build and quietly removes the part of the kitchen that was going to last twenty years.

Two made-to-measure quotations are rarely comparable as they stand, and the difference is almost never the total. Compare the gauge, the core, the front system, the runner rating, the insert system and whether the sink is welded or dropped in, and put those six beside each other before looking at either figure. A quotation that is cheaper by a fifth usually differs on two or three of the six, and it is the buyer who discovers which two at year three instead of at order stage. Ask for the specification in writing as part of the quote instead of as a follow-up email; a supplier who will name it in the document is naming something they intend to be held to.

Payment follows the same logic. Material is supplied with a mill certificate carrying a heat number, a third-party test report and compliance with ASTM, REACH and RoHS; standard production runs about thirty-five working days from the approved drawing. With the fastest series at about twenty-five, on fifty percent with the order and the balance before shipment by T/T. Packed to sea standard with pearl wool and corner guards under a ten-year warranty on the cabinet body written into the contract.

Custom against off-the-shelf: how to choose

Not every kitchen needs made-to-measure work, and the honest answer is that a rectangular room with standard appliances is the one case where a catalogue kitchen can genuinely compete. The test is the number of things that do not fit a grid, not the room size.

• Count the obstructions. A column, a boiler, a pipe run or a door that opens into the run is one point each. Two or more and the drawing is doing real work.
• Measure the wall in three places. If the ends differ by more than about 10 mm, a standard run will need fillers or a scribed panel and a custom run will absorb it.
• List the appliances and check their real widths. A 596 mm oven in a 600 mm housing is fine; the same oven drawn at 600 mm is a call to the factory.
• Work out the storage you are bringing across. If the answer is "the same as before", a standard layout will do. If it is "the big pans, the trays and the bin beside the sink", that is a plan.
• Decide where you want the custom money to land. Carcase and interior first, worktop and sink second, front last.
• Ask what is fixed. A supplier who says everything is customisable has not understood the question; the useful answer names the dimensions that should not move.

Custom kitchen cabinets: eight questions

These are the eight that come up most often on this subject, answered briefly so the detail above can carry the rest.

Where to go next

Send a dimensioned plan with the obstructions marked and the appliance schedule attached, and the reply comes back as a drawing instead of a brochure: the run cut to the room. The column resolved, the drawer heights set against what they will hold, and the grade, the gauge, the front system, the hardware rating and the lead time named in writing. The product tickets show the systems this is measured against, the Aarhus light grey run is a made-to-measure kitchen with the appliance column drawn in, and the Copenhagen pantry wall is a full-height block built as one piece. The delivered projects show how a plan like that is packed and installed, and the quality process sets out what is recorded before a set is crated.

If the room itself is the open question, the custom builds guide works through the awkward shapes one at a time, and the step-by-step trends guide puts the decisions in the order they are taken. Two more that pair with this guide: the 2026 renovation ideas for work that starts from an existing room, and the small kitchen ideas for the sizes a tight plan can take.
