I would like to add a secondary return air vent (12"x12" - 10" round flex
duct) in a bathroom, but I've always heard to never put a return air vent in
a bathroom. This would be in addition to the existing 16"x25" return air on
the other side of the house. The upstairs of this house has a 2.5 ton A/C
unit which the 400 sq in. filter return air is simply not adequate (14"
flexible duct). The existing return air cannot easily be enlarged due to
structural issues, while the addition of a bathroom return air could be
easily added.

is odor the primary reason not to put a return air vent in a bathroom? Will
excess humidity cause any issues?

The house I plan to put this in has a larger vaulted ceiling bathroom with a
separate small commode room, so odor is unlikely to be a problem, and the
bathroom is very convenient to the A/C evaporator.

Comments?

#1 reason would be... it's against the current "Mechanical Code".

Wait till your whole family has gone to dinner at a Mexican restaurant
and everyone is drinking. Then let us know how well that return in the
bathroom works out for you.
