A wall of built-in ovens is the least informative display in any appliance showroom. Twelve black glass doors at eye level, identical from a metre away, and a card under each one counting functions you will never say out loud.
Most people arrive at that wall the same way: mid-renovation with a hole in the cabinetry and a cooktop already chosen, or standing over an oven that died in the middle of something. Either way the spec sheets compete on function counts, because that is the one axis where an extra number costs the manufacturer nothing. None of them counts the Sunday you'll spend on your knees with a scourer.
That Sunday is the decision. How an oven cleans itself changes how its cavity is built, which cavities it comes in, and what you'll be doing on your weekends for the next decade. This guide settles three things: how it cleans, what fits the hole you have, and whether steam is one feature or two.
Start with how it cleans
Across the 360 ovens we list, 260 state a cleaning method. They fall into three real mechanisms, plus a coating:
- Pyrolytic: 139 models - by a distance the largest stated group
- Hydrolytic or steam clean: 55
- Catalytic liners: 28, plus 36 with an easy-clean coating
- Manual: 2
The remaining 100 state nothing at all. Worth knowing: a blank in our data is not a manual oven. It's an oven whose spec sheet didn't say, and it's why every figure here comes with the number behind it.
Pyrolytic heats the empty cavity far past any temperature you'd cook at and burns what's inside down to a fine ash you wipe out once it's cold. The door locks when the cycle starts and stays locked until the oven has cooled. That mechanism costs you three things: the racks come out unless they're rated to stay in, the kitchen wants ventilating, and the room gets hot while it runs. Run it on a February afternoon and you'll only do that once.
We don't publish the cycle temperature or how long it takes, because our records don't carry either. The temperature figures we hold are cooking maximums, and a cooking maximum is not a cleaning cycle. Where a number would be an invention, you get the mechanism instead.
Here is the part that decides more than it looks like it should. Pyrolytic is a built-in-cavity feature. It's on 73 of the 152 single ovens we list and 42 of the 78 steam ovens - but on 4 of the 50 freestanding cookers, and 3 of the 28 typed as doubles. If a freestanding cooker is what your kitchen takes, you have already chosen against pyrolytic cleaning, whatever the showroom offers you afterwards. Gas ovens are almost as thoroughly out: 2 of the 27 we list.
Catalytic liners are a porous coating on the cavity walls that absorbs spattered grease and oxidises it during ordinary cooking, so there's no separate cycle to run. What the mechanism costs you is at the edges: it works on the walls, not the base or the door, so anything that lands on the floor of the cavity is still yours to deal with. And liners wear out. They're replaced, not renewed.
Hydrolytic and steam cleaning heat water in the base of the cavity and let it soften what's stuck there so it wipes off. It loosens; it doesn't burn off. That makes it a weekly habit rather than an annual rescue, and the difference shows up after the first roast you don't get to for a fortnight.
But consider: you'll want to know what a pyrolytic cycle costs to run, and we won't tell you, because we can't. Australia's GEMS scheme doesn't star-rate ovens, and only 53 of the 360 ovens we list publish a per-cycle energy figure at all. We also don't list oven prices yet - our oven records don't carry them - so we won't pretend to know what the pyrolytic premium is either. A number we can't derive is a number we don't print.
What fits the hole you have
Oven widths are not a continuum, and shopping them as one wastes a fortnight. Across the models we list, the widths cluster into installation classes with nothing between them: 259 at the 60cm class, 54 at 90cm, 27 at 76cm, 15 at 54cm, and 5 at 110cm. In between, our catalogue is empty - not one model between 601 and 697mm, and not one between 761 and 849mm. You are choosing a class, not a dimension.
Pro tip
The width in the product name is the appliance. The number your cabinetmaker needs is the cavity opening, and it's a different number: of the ovens we list that state a minimum niche width, 75 of 79 want 560mm, against a median appliance width of 596mm. The joinery is built before the oven arrives, which is the wrong order in which to discover a mismatch. Take the niche dimensions from the model's own documentation.
Two capacity figures get quoted and they aren't the same thing. Across the models we list, gross capacity runs a median 80L and usable capacity a median 72L. On the 227 models that state both, usable is the smaller figure on 164 and identical on 58, and where the two differ the gap runs a median 8 litres - the space taken by shelf runners, the fan housing and the door seal. Five rows read the other way round, which is a spec-sheet error we report rather than quietly correct. Usable is the honest figure. Brochures lead with the other.
Below that sit two classes that aren't main ovens at all: compact ovens (26 models, a median 45L usable) and combi-microwave and speed ovens (26 models, 40L). Both are built to stack above or beside a full-size cavity as a second oven. Sized as a household's only oven, they will disappoint at Christmas.
Double ovens need a caveat, and it's ours rather than the manufacturers'. Our catalogue types 28 models as double ovens, but 14 of those are freestanding upright cookers that happen to have two cavities, not built-in pairs - 9 of them at 54cm wide, 4 at 110cm. The genuine built-in group is the other 14, and 9 of those are one brand's twin-cavity ovens. We're reclassifying this at the next catalogue import. Until then, if you want a built-in double, read the product name before you read the type.
If you're replacing the cooktop in the same renovation, settle that first: our cooktops guide covers which fuels your kitchen can already give you, and that answer constrains the bench, not the oven cavity.
Steam is two appliances wearing one word
134 of the models we list offer steam, and the word covers two different machines.
Steam assist adds humidity to what is otherwise a fan-forced cycle. It's for crust and colour on bread and roasts. Full steam uses steam as the cooking medium, which is a different appliance in the same cabinetry - it can cook at and below 100°C, and it can replace a stovetop steamer rather than flavouring a bake.
19 of the 134 are full steam, and 17 of those 19 are dedicated steam ovens. It isn't a function that gets added to a normal oven; it's a category you buy into.
Which leaves a third thing, and it is the biggest of the three. Only 56 of the 134 say in their own spec sheet which kind of steam they have - 19 say full steam, and 37 name an assist function or a brand's steam program. The other 78 don't say. Some are blank, some say "not applicable", some just say "yes", and a handful have a list of cooking modes sitting in the field where the steam type belongs.
We used to group those 78 with steam assist, which made a tidy 115 and was the wrong shape: "we don't know" is not a quieter version of "it's an assist oven". They now count as neither. If you pick either kind in our quiz, a model that doesn't say scores in the middle - not ruled out, not credited - and the card tells you its type isn't stated rather than guessing for you.
Then the finding that costs someone a decision. Of the 19 full-steam models we list, exactly 1 is also pyrolytic. The two features a showroom will push hardest almost never share a cavity. We can't tell you from the data why that is - what we can tell you is that if you want both, you are looking at a very short list, and the honest move is to decide which of the two you'll actually use weekly.
What you can safely ignore
Air fry. 156 of the ovens we list have it and 170 explicitly don't, so it's a real split rather than a marketing universal - but it's a fan program with a name on it, not a separate machine inside your oven. The same fan and element run harder and faster. If the oven you want has it, use it. It isn't a reason to choose one.
Wi-Fi. 192 of the models we list carry it. An oven is a thing you stand in front of, and preheating from the tram is not the problem your kitchen has.
Function counts. Across the 269 models that state one, the median is 10 functions and the range runs to 28. The ones that matter are fan-forced (231 of the 360 we list state it), a grill, and conventional heat. A fan-forced oven reaches a given result at a lower dial setting than a conventional recipe assumes; we won't put a figure on the offset, because that figure isn't in our data either. Everything past the first handful of functions is a menu you'll scroll through to reach the mode you always use.
Energy letters. 86 of the 360 ovens we list carry an energy class, and it's a European letter, because GEMS doesn't rate ovens in Australia. It cannot be compared with the star rating on your fridge, and 274 models carry nothing at all. There's no efficiency ranking to shop here, which is precisely why we don't offer you one.
Branded cleaning names. Every manufacturer names its cleaning system something proprietary, and the spec sheets read as though these are competing technologies. They are the three mechanisms above: burn it off, oxidise it as you go, or soften it with water. Find the mechanism, then check which one the name is wearing.
You now hold the two answers this decision turns on: the cleaning method your cooking justifies, and the width class your cabinetry gives you. Everything after that - capacity, functions, probes, runners - narrows a list rather than deciding one.
Take the oven quiz and it'll work through the rest against the 360 models we list, with the reasoning shown on every match.
