Hi,

Random question but does anyone have the optional dovetailed oak cutlery drawers fitted to a DIY Kitchens unit and can tell me what the clearance is like above it?

Basically got a kitchen arriving this week and need to get the worktop ordered from a local place... we want to go for 20mm Quartz (as it looks better and also saves us over £500 Vs the 30mm)

The thing I'm in a panic about is the depth of the (Miele) induction hob is 47mm (from the underside of the glass) and I'm worried the drawer will be unusable...

I have bought an Ikea NYTTIG (hob / drawer protector) which is a 7mm sheet of material with a 17mm lip which would work and I could reduce the depth of the lip I think - maybe 10mm from 17mm by fitting the overlap the other way round.

Howdens do a similar product -

So with the 20mm worktop, there would be the 18mm top of the carcass, then the 17mm then the 7mm seperator gives at least the right clearance for the hob.

I'd need someone to tell me the measurement from the top of the drawer to the bottom of the worktop and I'd need 35mm min and ideally 45mm

I'll give DIY a call in the morning I think but another option would be to change the hob - does anyone know of any slimmer Induction hobs or brands to look at?

Not sure if the height of the drawer sides vary, probably not. My DIY drawer sides to worktop clearance is 48mm.
Mines an AEG induction hob over a double oven, with a 30mm Quartz worktops. It was tight to get the hob manufacturers clearances. Hopefully not such a problem with a drawer.

Thanks for that - take it that's the standard metal Blum drawers?

Yeah = I was thinking the drawers would be better in terms of heat vs having an oven underneath but we kind of decided on the 20mm worktop for the reasons above and I thought the hob depth was under 40mm until I measured it properly!

Yes standard Blum drawers, it looks as though it will all go in as you planned.

Beware the 20mm quartz. It's very thin, and very heavy, and very unpredictable being a natural material with imperfections. It's just not strong enough along the narrow bit in front of cutouts for sinks/hobs etc, especially with the current trend for 90cm wide hobs. It can crack under the weight of each end flexing it during fitting just from moving it the wrong way.

Make sure it's perfectly level in place, well supported underneath during install and afterwards, and make sure you've got a bombproof contract with the installer. Don't lean on the worktop in front of a cut-out, ever.

Better still, go for 30mm. Don't save a few quid in this area, or it could get very expensive down the line if it breaks in a year when a guest leans on it.

I do understand the attraction of the slim, modern look with 20mm, but don't do it as a cost-saver. Wrong place to economise, IMO.

Thanks for that - I may well just go for the 30mm - shame they don't do a 25mm!

Hob is 780mm wide on an 800 drawer unit - will speak to the company later to discuss!

I had a similar issue on my diy build, I had one of the units with the additional internal cutlery drawer and for my induction AEG hob and 30mm granite top I had to cut a sliver off the back of the drawer to clear the deepest bit of the hob where the electrical connections are made..

We have 20mm quartz over a 1000 drawer unit, but the hob is only 650 wide. The top drawer has a reduced depth to allow for the induction connection and we just use anti slip mats in the drawer rather than an insert, which actually makes things much easier.

What a load of tosh, Quartz worktops are made made. If properly supported 20mm will be fine with a 90cm hob.

Also, get a separate quote from a local solid worktop supplier. Our local guy could fit 30mm £2k cheaper than Howdens could fit 20mm. The selection was also much wider and we really got what we wanted. The kitchen companies dont install there own worktops anyway, they get a contractor in.

Indeed they are. My apologies. My experiences were all granite and natural stone. I actually have no knowledge of whether the same problem exists in Quartz.

Statement withdrawn, and thanks for the correction.

I have a DIY kitchens draw - with cutlery tray from them too - under an induction hob without any problems. My worktop is wood though.

My induction has fans so it never occurred to me to fit the protector thing. Won't it impact airflow? Stuff in the draw doesn't get hot.

Interesting I have same dilema I was about to order 20mm Quartz tonight and suddnely worred about the Hob... I am looking at AEG 44mm clearenace with a double oven to fit into DIY Cabinets thinking maybe wise to go for 30mm quartz based on your comments?
