Wall, Island or Slimline? Find the Right Hood for Your Kitchen
Wall, island or slimline: how to match a cooker hood to your hob position, ceiling and duct route, and why the shape of the canopy matters as much as the finish.
Stand at the hob at seven in the evening with a pan of onions going and watch the steam. It does not rise in a tidy column. It leans towards the open window, curls off the front of the pan towards your face and drifts into the next room the moment someone opens a door. A cooker hood’s whole job is to be in the right place when that happens, and the three main types go about it in different ways.
So before you choose a finish, look at the room. Where the hob sits decides which kind of hood belongs above it. How the air leaves the house decides how well that hood will work. Everything else, from black glass to gesture controls, comes after those two answers.
The starting point
Pick the hood type from where your hob sits. Then check coverage, the duct route, the noise you can live with and how easily you can reach the filters.

Three shapes, three starting points
A wall hood sits over a hob that backs onto a wall, usually as a chimney, a flat canopy or an angled glass front. An island hood hangs from the ceiling above a hob in open space and is seen from every side. A slimline hood tucks beneath a wall cabinet, so the upper run of cupboards stays unbroken and the hood all but disappears.
These are arrangements, not rankings. A big statement hood on a poor duct will disappoint, and a modest one sized properly for the hob can be a pleasure for years. Choose the type your room calls for first, then compare models within it.
Newmatic’s extractor collection covers all three: island, wall-mounted and slim models. Treat them as three different jobs rather than one design squeezed into every kitchen, and check the fixing method for the exact model you like. Two hoods that look alike in a photograph can need quite different brackets and ducting.
The wall hood: the straightforward choice
If your hob sits against an outside wall, or close to one, a wall hood is usually the simplest and most effective answer. The duct run is short, the wall shelters the cooking from cross-draughts, and the island stays free for chopping, serving and the friend who leans on it with a glass of wine. The hood also becomes the focal point of the cooking wall, so plan it with the splashback and cabinets as one composition.
Do a dry run in the showroom. Stand where you normally stir a pot and look up. Can you read the controls without craning? Does the canopy loom over your head at the height the installer will use? Can you get the filters out without climbing on a chair? A glass hood loses its charm quickly if cleaning it feels like a workout.
Look either side of the hob as well. A tall larder unit hard against one side makes the cooking zone feel pinched, even when the hood technically fits. Ask your cabinet maker and appliance installer to mark the final hood position on the same wall drawing before you order tiles or stone, so nobody discovers a clash after the splashback is up.
Island hoods: plan the ceiling first
Cooking at an island has an obvious appeal: you face the room, not the wall. But the hood above it is now part of the view from the sofa and the dining table. Cut a full-size cardboard template of the canopy, hold it up at the planned height and look at it from where you will sit. Ten minutes with tape and cardboard tells you more than an hour with a brochure.
Island hoods also lose the wall’s help. In tests at Lawrence Berkeley National Laboratory, moving a hood just 15 cm forward from the back wall noticeably reduced how much of the back burners’ fumes it caught. Over an island there is no wall at all, so draughts from doors, windows and ceiling fans pull the plume sideways. That is why kitchen designers often give an island canopy a little overhang beyond the hob on each side.
Then there is the ceiling. It has to carry the weight, hide the duct and leave room for lights, and a concrete beam in the wrong place is an expensive surprise once the plaster is finished. Settle hood, lighting and ceiling works together, and agree how someone will reach the motor for servicing in a few years’ time. While you are in the showroom, ask to hear the hood on its everyday speed, not just on full, because over an island you will be talking across it.
Slimline hoods: mind the front burners
A slim hood makes sense when a continuous run of cupboards matters more than a chimney. In a compact kitchen it keeps the cooking wall calm and the storage intact. Before you commit, ask exactly how much cupboard space survives once the hood and its duct or recirculation kit are in place. It is often less than the cabinet plan suggests.
The bigger question is coverage. The same Berkeley tests found that hoods caught fumes from the back burners far better than from the front, and that a short, shallow hood with its intake underneath did worst at the front, catching under half in some runs. Slim hoods are shallow by design. So use the back rings for anything that spits or smokes, and if your model has a pull-out visor, pull it out.
Access matters too. You should be able to drop the grease filters, wipe the underside and reach the controls without opening the cupboard next door. If there is a sliding visor, check it travels fully once the cabinet doors and handles are in place. These are small things to test in a showroom and irritating things to discover after the kitchen is finished.
The duct route matters as much as the hood
Whichever shape you choose, its performance depends on where the air goes next. A ducted hood pushes it outside; a recirculating hood filters it and sends it back into the room. That is a decision in its own right. The point here is narrower: if you are ducting, the route you can actually achieve should shape the hood you buy, not the other way round.
Every bend costs airflow. One major appliance maker’s installation guide counts a single 90-degree elbow as equal to about 1.5 metres of straight duct, so two elbows and a short run quickly add up to a long journey for the air. Keep the duct at the size the hood specifies, never step it down to a narrower pipe, and plan the shortest, straightest route the building allows. Ask the installer to sketch it before ceilings or cabinets close off the options.
In a renovation, have the existing duct inspected rather than assuming it suits the new hood. Check its diameter, condition and route, and where it ends outside. In an apartment, find out what the building allows before you plan anything. A bigger airflow number on the box cannot rescue a duct that is too narrow, too long or has nowhere sensible to discharge.
The details you notice at dinner time
Airflow figures only mean something in context. Ask whether the number describes the motor on a test rig or the hood as installed, and compare like with like. What you actually get depends on coverage, duct resistance and how you use the hood, not on the biggest figure on the label.
Lighting deserves more attention than it usually gets. Hold your hand where the front of a pan would be and see whether the light lands there or on the back of the hob. Shadows over the front rings make it harder to tell whether the garlic is golden or burnt.
Controls are something you touch every day. Touch panels, buttons and gesture sensors all work, but try them from your normal cooking position with slightly damp hands. Choose the one you will use without thinking, not the one that sounds cleverest in the showroom.
Filter care belongs in the buying decision too. Find out which filters can be washed, how, and which need replacing. Write the filter reference down next to the hood model on day one. The easier the routine, the more likely it is to happen.
Three kitchens, three answers
A compact apartment with the hob on a wall: compare a slim hood with a wall model before redesigning the whole cabinet run. If upper storage is precious, the slim hood wins. If you fry often and the space allows, a wall hood’s deeper canopy will catch more of what comes off the front of the pan.
An open-plan kitchen in a household that fries regularly: think hard before moving the hob to the island. An island makes a generous prep and serving surface, and keeping the hob on the wall can be a deliberate choice that makes ventilation easier and the living area quieter.
A household that already loves its island hob: concentrate on canopy width, ceiling support and the duct route. Judge the proportions sitting down at the table, not standing next to the display. A hood that looks huge in a showroom often settles into a tall room perfectly well.
Before ordering anything, put the hob model, hood model, mounting height, duct specification and cabinet drawing on one page, and ask everyone involved to work from it. Changing a drawing costs nothing. Changing cut stone, finished cabinets or a plastered ceiling costs a great deal.
Questions worth asking before you buy
Can I put a wall hood over an island?
No. Use a hood designed and approved for that position. A wall model relies on the wall for its fixings, its finish and part of its air path, while an island hood comes with ceiling supports and is finished on every side. The same width does not make them interchangeable.
If I cook on induction, do I still need a hood?
Yes. Induction removes the flame, not the food. Searing a steak or stir-frying on induction still throws off steam, grease and smell, so plan extraction around what you cook rather than what you cook on.
Is a wider, more powerful hood always better?
Not automatically. A little extra width helps catch the front of the pan, but a powerful hood on a narrow, twisting duct, or one too loud to leave running, does less good than a well-matched quieter model. Ask for a recommendation that covers installation and care, not just the hood.
When you look at Newmatic cooker hoods in a showroom, bring a floor plan and a few photos of the wall or ceiling where the duct would run. Settle where the air will go and how the hood will fit first. The finish is the enjoyable part, and it is far easier to choose once the practical questions are answered.
