Which recirculating induction hob will fit my island cabinets?

[YorkieSelfBuild]

Hi, I'm having trouble finding a downdraft recirculating extractor induction hob to fit regular British units in an island. 

 

I had planned a 80cm hob but they all require lots of room underneath the worktop. I can widen the unit to 1000mm to handle width and height under the worktop isn't an issue, as I know there's some unusable space. 

 

The real problem is depth from the front of the worktop to the back. DIY Kitchens base units are 560 but most hobs need 480-600mm plus a 25-100mm gap for venting, with or without a duct, down the back then underneath to the front plinth which will have a cutout. The attached image is just one model.

 

Do other kitchen companies make deeper units? I can change from drawers to shelves but I'm still limited to 560. I thought they're 600 deep so is there a 40mm void?

 

Do I sacrifice the units on the back of the island? So they mirror the front but have only shallow cupboard units on each end with a dummy panel behind the hob unit? 

 

Any suggestions are welcome!

 

The alternative is a smaller 72cm hob, I've seen the Elica NikolaTesla FIT, but I would really prefer 4 full size pan areas (plates, burners or whatever you call them 😄)

Is making the island 100mm deeper an option? You'll have end panels covering the sides of the back to back cupboards.

 

Otherwise change the 2*900 wide cupboards at the back to 3*600 so you only lose space in the middle one?

Can you not just put a void between the two sets of cupboards, pack it out with some timber. 
you would need larger end panels obviously. 
have you included the service void that is behind your cabinets in your measurements. 
 

@torre snap.

I can't go deeper, need clearance next to dining table, but making the middle unit the smallest available is a possible idea, thanks!

Like Torre's idea, I can't go deeper with the island but there's a 42mm service void. Waiting for confirmation it's twice that with back to back units and if it's the same for shelves and drawers units 

 

Also waiting for DIY Kitchens support to tell me how big is the internal gap behind drawers to backing board.

Have you seen this from Neff https://www.neff-home.com/uk/en/mkt-product/hobs/accessories/Z861KE1

No but it's similar to other hobs. Not sure if "ducted" means external or recirculating. But I didn't know these ducts reduce noise levels. I had thought they weren't necessary but now I'll look for one that will fit. Thanks!

Have you considered an extractor in a drop down ceiling 

 

now I’ve seen those other diagrams, isn’t it a simple job of getting the drawers made with a reduced depth.

Is the duct rectangular? 99mm deep shown by maybe twice that wide? That is a big duct compared to the standard 110mm round ones.

Maybe they can accept narrower like this.
