Counter depth needed for a Bosch Induction cooktop
I'm considering putting a pop up downdraft behind a Bosch cooktop. When I looked at the specs of the cooktop it is specified that 2.25" is the minimum distance needed from the front of the counter and 2" is the min. distance from the back. Thus 4.25" + 21.25 " (depth of cooktop)= 25.50". Isn't the normal depth of counters 25" ? Do you bump out or make the whole run deeper? Also, does anyone have a pop up vent behind a cooktop? And if you do, how deep is the counter? Thanks for any input you may have.
