Okay, so that would vent the bathroom correctly then. Okay, super. That's the worst thing a home inspector found. By the way, good idea having that house inspected before you put it on the market, because this way you know what you have to deal with before a buyer's involved. So good idea doing that, and if this is the worst problem they found, I think your house is in pretty good shape.
