Can i ask what is the difference of installing a built in oven at waist level, slightly below waist line and underneath the hob?? I have a very limited wall space in my new house. If i put the oven at waist line, meaning I'll probably lost out a full height cabinet which i really want.

A KC installer tell me is because if it is underneath, the steam/heat of the oven will easily hurt the person because steam comes out quickly from the oven.

what is ur suggestion?
