Your Dishwasher Belongs in the Kitchen Plan Before the Cabinets Do
A dishwasher chosen after the cabinets tends to fit on paper and fight you every evening. Here is how to plan one in from the start, from the open door to the drain hose.
Ten o’clock, the end of a dinner for six. Someone is scraping plates, someone else is loading, and the open dishwasher door has turned the kitchen into a dead end. The bin is trapped behind it. The cupboard for the clean plates is on the far side of it. Nobody planned this. The dishwasher simply arrived last, after the cabinets, and was given whatever gap was left.
It is a common story because the dishwasher is usually the last appliance anyone thinks about. It should be one of the first. It decides where dirty plates wait, where clean ones go and whether two people can tidy up without bumping elbows. Settle those movements on paper and the cabinet maker has a much easier job.
The starting point
Put the dishwasher on the plan while the sink, cabinets and plumbing can still move. Judge it with the door open and the racks out, not just shut.

Follow a dirty plate
Take one plate on its whole journey. It leaves the table, the scraps go into the bin, the plate goes into the rack, and an hour and a half later it comes out clean and goes back into a cupboard. Draw that loop on your floor plan with a pencil. Where it crosses itself, or crosses someone else’s path, there is a problem waiting.
The dishwasher almost always belongs beside the sink, but which side matters. A right-handed person scraping at the sink tends to load to their left; a left-hander the other way. Think about where a second person stands, too. The dishwasher should not take the only stretch of worktop where someone can chop while the other clears.
Then place the bin and the plate cupboard around it. The bin should stay within reach with the dishwasher door down. The plates and glasses should go away from a spot where you can stand comfortably with the racks pulled out, ideally without walking round the open door.
The door is part of the footprint
A closed dishwasher is 60 cm of cabinet front. An open one is that, plus a door lying flat at shin height, plus a rack pulled out over it, plus a person bending over the lot. Draw all of that on the plan and look at what else is trying to use the same floor.
Corners are where it usually goes wrong. A dishwasher right beside a corner can have its door blocked by the handle of the drawer around the corner. Ask the cabinet maker to check those clashes with real handle sizes and the finished thickness of the furniture panel, not with idealised lines on a drawing.
Unloading needs the same test. If the cutlery drawer is directly opposite across a narrow aisle, can it open while the dishwasher door is down? If it cannot, you will unload in two trips every day for the next fifteen years. Masking tape on the floor and a cardboard box for the door will tell you in five minutes.
Pick the model, then build the gap
Newmatic’s dishwasher range currently includes the DW12INT-2, a fully integrated model described as 60 cm wide with several wash programmes. That width is a shopping category, not a cabinet specification. The actual opening, the panel limits and the connection points come from the installation instructions for that exact model.
Fully integrated means the front is a furniture panel matching the kitchen. That panel still has to suit the appliance: its size, its weight and how it meets the plinth all affect how the door opens and closes. A door that is too heavy for its springs drops open with a thud; one that is too light springs back. Ask who fits the panel and how the door balance will be set.
Think about the floor before it is laid. If the new tiles go down after the dishwasher, or the floor is raised for underfloor heating, the machine can end up trapped in its housing. Ask how it will slide out for a repair once the worktop and floor are finished, and draw that in.
Water in, water out, power
A dishwasher needs a water supply, a drain and a socket, usually all sharing the cupboard under the sink. Let the installer plan all three for the model you have chosen, following its instructions for hose routes and connection heights. Hoses squashed into a gap behind the machine are the start of many slow leaks.
The drain hose is worth a second look. Most installation guides ask for it to rise in a high loop, fixed just beneath the worktop, before it drops into the sink waste. That loop stops dirty sink water from siphoning back into the dishwasher. Some places require a separate air gap instead, so follow local plumbing rules and the manual.
If your home runs on a storage tank, a booster pump or a supply with variable pressure, tell the installer early. Dishwashers are designed for a particular range of water pressure, and it is far easier to confirm the supply suits the model before purchase than to improvise a fix after the machine is fitted.
Bring your own plates
Dishwashers are rated by place settings, a standard test load of plates, bowls, glasses and cutlery. Your crockery is not that test load. Wide pasta bowls, oversized dinner plates, tall mugs and lunch boxes all take up space differently. Take a few of your own to the showroom, or at least their measurements, and try them in the racks.
Put your tallest wine glass in the top rack and your biggest plate in the bottom one, at the same time. If the top rack adjusts, ask how, and what you give up when it moves. Flexibility only matters if it makes room for the things you actually wash.
Look at cutlery too. A removable basket suits people who carry everything to the drawer in one go. A flat cutlery tray at the top suits those who like knives and spoons laid out in rows, and frees up space below for pans. Try your longest ladle and your serving spoons in whichever arrangement the model offers.
Load it like you mean it
Scrape, do not rinse. Consumer group CHOICE notes that many machines run an early rinse and use how dirty that water is to judge how hard to wash. Pre-rinsed plates can fool it into an easier cycle. Rinsing under a running tap also wastes the water the dishwasher was meant to save.
Give the water room to work. Plates should face the centre, bowls should not nest inside each other and nothing should block the spray arms or stop the detergent flap from opening. Follow the rack layout in the manual for your machine. A shaded plate behind a large platter is the usual reason for one dirty dish in an otherwise clean load.
Agree a household system. Mugs on this side, bowls at the back, knives handles up. It sounds fussy, but it means anyone can finish loading without rearranging what is already in there. Keep good knives, wooden boards and anything with a delicate finish out of the machine unless the maker says otherwise.
Why eco takes so long
The eco programme is often the longest on the dial, sometimes more than three hours, and it is usually the cheapest to run. Most of a dishwasher’s energy goes into heating water. Eco uses less water at a lower temperature and makes up for it with time, letting the detergent soak and work rather than blasting it hot.
So the clock is not a good guide to cost. A quick 30-minute cycle is handy for lightly used glasses after a party, but on a full, greasy load it may leave a film behind. Check the manual for what each programme is designed for, and use eco as the default for the everyday load.
Running a full machine pays off too. In a well-known study at the University of Bonn, people washing by hand used about 100 litres on average for a load a dishwasher handled with about 13, according to a CHOICE summary of the research. Wait until it is full, and never put ordinary washing-up liquid in it: the foam will escape across the floor.
Five minutes a week
Most of the grime in a dishwasher ends up in the filter, a small cylinder in the floor of the tub. Ask the showroom to show you how it lifts out and goes back in. Then do it every week or two: rinse it under the tap and give it a soft brush. It takes less time than making a cup of tea.
Every so often, check the spray arms spin freely and their holes are clear. A grain of rice or a shard of glass can block a jet and leave one corner of every load dirty. The manual will say which parts can be removed and how. Keep it somewhere you can find, not in the drawer next to the takeaway menus.
If dishes start coming out dirty, go through the simple checks first: loading, filter, spray arms, rinse aid and salt if your machine uses it. Most problems are found there. A fault that keeps coming back belongs with the service team, not with a stronger detergent or a home repair.
The handover
Before the installer leaves, ask to see the door open and close with the final panel on, both racks slide out fully and a programme start. Open the drawers and cupboards next to it with the dishwasher door down. Check the connections are dry and that the service access has not been closed off by the finishing work.
Write down who to call for what: one number for the installation, another for the appliance. Keep the invoice, model number and warranty together. If the cabinets and the appliance came from different suppliers, note who did which part. It makes the small adjustment that always comes up a short phone call rather than a long argument.
Is a dishwasher worth it in a small kitchen?
Often, yes. It keeps dirty dishes off a worktop you cannot spare and usually uses less water than washing up by hand. The cost is a 60 cm cupboard. If that space is precious, look at your daily load honestly before deciding.
Where is the best place for a dishwasher?
Next to the sink, on the side that suits how you clear, with the bin and the plate cupboard within reach of the open door. Explore Newmatic’s built-in dishwasher while your kitchen is still on paper, and the end of every dinner will be a little easier.
