Replace same size hob in Granite Worktop

dust_bunnies

Hey, is it feasible to replace a gas hob with induction hob of same size on a granite work top?

I am redoing the kitchen cabinets, but the worktop is a good quality granite and I cannot afford to get something of the same quality. Was considering retaining the worktop, but only replace the hob with something of the exact same size.

You'll need to measure the cutout hole in the granite, from underneath if it's all still in situ, to see what size it is and then find an induction hob that will fit with it. In principle it could work but will really depend on the old hob

You need to measure the cut out in the worktop. Then look at the installation manual for your chosen hob. If the hole is a few millimetres larger (up to 10mm ?), the induction hob will drop straight in. Any smaller, and the hole would need to be enlarged - This can be done with careful use of an angle grinder & diamond disk or a router with the appropriate cutters. A dirty & dusty operation that many fitters would probably decline to undertake.

if you do decide to do it just be super careful because obviously where the hole is cut out the granite is very weak being supported just by the two strips each side of the hole

Yes it's do-able if the existing hole is actually the right size for the new hob.  You'll need to check the installation instructions carefully, as the hole may need to be smaller or larger than might be apparent just from looking at the top surface of the hob.  If the hole needs to be enlarged slightly, that's not too difficult.  If it's too big and needs to be reduced - it can be done, but will take a fair bit of fiddling.

You'd also need to check whether you've got a suitable electrical connection available.  It's quite likely that there's a standard 13-amp socket/fused spur available that was used to power the ignition for the gas hob.  This may well be sufficient, but a lot of induction hobs will draw more than 13 amps, especially if you're using all 4 "rings" at the same time.  So you may need to get a larger "cooker" circuit installed if there's not one there already, which you'd need an electrician for.

Are your saucepans suitable?

Yes, my previous rental had induction hob, so I do have all the utensils. Since I am remodelling the kitchen at my home, thought of replacing the gas hob.

Just throwing this in there FWIW, I just had my kitchen replaced and went from a free standing gas cooker to integrated electric oven and a gas hob fitted in a worksurface. The reason I kept the gas hob was a) I prefer hob cooking on gas and b) that if ever there were power cuts I still had a means of cooking. I know most power cuts are fairly short and most people are not bothered about that possibility, but I just didn't fancy being reliant on one power source.
