venting hood into bathroom vent?
I am planning a kitchen overhaul and have hit so many road blocks. Here is my last one I hope. I need to add a vent hood for a gas AGA stove. I either need to go up 7 feet, through a drop ceiling(drywall) and over 8 feet to an external brick wall OR go up about 7 feet and tap into the vent tube from the bathroom which is located behind the wall. It looks like that vent is only a 4 or 5 inch circle though. What option is the right one?
