how much "breathing room" around a microwave on a shelf?
The shelf can be up to 36" wide and we haven't picked out the MW yet. I was thinking of having it in a cabinet box on its own, with bookshelves alongside and above. I suppose it would be simplest just to allot the whole 3 ft and have more choices, though. We don't use it a lot and it will be out of the way in a corner if that matters. I see a lot in the 21-24" wide range. Would a 24" space be too small?
