I bought a large induction hob a while back and decided for safe keeping would leave it boxed until I needed to install it. So retrieved the instructions to check out all the dimensions of the cut out. Started to prepare the worktop today, as the hob spans two base units I had before installing the base units checked the clearance. According to the instructions from the top of any worktop the hob needs 35mm of clearance so with a 40mm deep worktop no problem. I cut out the hole drop the hob in place only to find it rocking on the base unit sides. Turns out the hob is 50mm deep so what would have been an easy modification to the base units before installation now is a real PITA. Grrrrr!
