Hob size confusion, can any kitchen fitters/sparkie's comment?

Hello. I'm feeling a bit stupid asking this but .....

We bought an ex-display kitchen from Mfi in the closing down sale. This kitchen came without the electric hob which was already sold. I am positive the bloke I dealt with said ''you realise it's a 90cm hob that goes in there?'' Anyway I've been keeping an eye out for 90cm hob's on ebay for local collection and one's come up - so I thought I'd double check my memory was right on the 90cm. It's a walnut worktop with the hob cutout already done - but the width is 75cm??

So my stupid question is .... should the hob I get be 90cm with the 15cm extra ( 90cm - 75cm ) being overhang for the sides ?? Or was the bloke wrong/my memory wrong and I should be getting a 75cm hob ?? I realise I can get the walnut cut, but I might as well just buy the right size to fit the hole as I'm not particularly bothered about the size hob I wind up with.

    the only thing that i can suggest is to go to a store that sells hobs and measure 1 that is 90cm and 75 cm. alternativly you can tell a salesman what size hole/cutout that you have and see what they recommend. i am not sure of this, if you look on the internet at buying a hob if they will tell what size hole/cut out is needed.

    I'm certain that you look for a hob with an aperture width and aperture height to suit the hole in your worktop.

    This one (as an example) has an aperture width of 555mm and aperture depth of 510mm but the actual size of the hob is 750mm x 510mm

    If you look at this hob, scroll to the bottom of the page it states the size of the hob and the aperture needed so gives you some idea

    Hobs are measured based on what you see when it is installed. The cutout is required to allow the deeper parts of it to sink into the worktop. The cutout is smaller to ensure that the lip around the hob can give support.

    If buying secondhand, make sure that you get the brackets along with it which clamp the hob to underneath of the worktop.

    I would say Dixons have made a mistake there. A 750 wide hob will need an actual cut out of about 720 mm width.

    You certainly cannot fit a 900mm hob into a 750mm aperture.
  • Every cutout for a hob is slightly different, depends on brand & model. Most Kitchen items like Hobs & sinks either come with a template or you use the appliance as a template to make the cutout. On a sink for instance the difference between cutout & outer edge of the sink is just 10mm:eek: . So the sink sits on this edge, a hob would be the same. The cutout is smaller than the appliance outer edge.


    It may turn out to be quite a challenge to get a hob to exactly fit your cutout. I'd suggest you get a 90cm hob that you like/can afford & recut the cutout to suit.

    Ok, I think I get the drift, it isn't as straightforward as I thought.

    I think I'll just keep an eye out for a bargain, and if one comes up either ebay or sales, I'll specifically check for aperture size needed. I can get the hole enlarged if needed ........... but I'll play it by ear.

    You see I thought they were 'set' stardards, but it seems they vary product to product, so I just need to be careful about it.

    Many thanks.

    The issue is really if the hole in the worktop is too big...if it's too small then as you say you can enlarge it. The other way of looking at the problem is to scrap the worktop altogether and try and source a new one that matches the rest and then you could get whatever hob you want (presumably smaller hob will be cheaper). Might be worth investigating and pricing it out .

  • The cut out is probably for a 900 hob. On most oversized hobs the cut out needed is quite a bit smaller thaqn the hob. Get the 900 and it will probably fit. IF not just cut a larger hole for it
