    Default changing cooktop vent from recirc to exterior vent

    My problem if a difficult layout for converting the recirculating cooktop vent to exhaust to the exterior? We just moved into our 2007 home and want the exterior vent. The vent hood is on an interior wall with the laundry on the other side. The master bath is right upstairs. Looks like the water supply for the laundry is in one of the stud bays behind the vent hood. Don't know if there is a bay clear for installing a vent. Assume that the water supply and drain for the bath routes through the wall close by, if not in the same bay. There is a finished attic and an HVAC unit above the 2nd floor bath so I assume that routing through to the roof is not an option. One path is through into the laundry room, then run to the outside wall - not the best. Another path if acceptable would be through the wall down into the crawl space and then outside. Through the crawl space is the longest path but has an acceptable equivelent length for the fan. I would reroute some water/drain lines to route the vent properly. What suggestions and advice can you offer?

    Does the wall the stove is on meet an exterior wall?

    If so, you may be able to run the duct vertically above the cabinets and along the wall to the exterior. You'll need to create a soffit by boxing in the vent -- you'll lose any storage space above the cabinets.

    A soffit really doesn't look that bad. Those decorative plates the lady of the house has up there just gather grease and dust anyway.

    As mentioned above the soffit route is a good option, but you really need to bring in a good professional remodeler to scope out your particular situation.

    There's a solution to every problem but I would need to be there to inspect every option to provide a reasonable solution.

    Isn't it a shame that the builder didn't vent to the exterior.

    Since venting must follow certain guidelines, not all options will be available to you in your particular situation. Consult with a professional.
