    Bath exhaust location

    I think I know the answer to my question but thought I would see what everyone else thinks. I need to add a bath exhaust to an old house. Attic access is sketchy until GC cuts access hole. There is a basement with easy access to bathroom floor. I was thinking about using an inline fan and connecting to a 10/8 bucket with a decorative floor register. Any opinions as to how well a floor exhaust would work in a bathroom?

    Not very well. Although better than nothing. <g>

    Both the smelly fumes and the moisture are at least 25º warmer than the bathroom - so they will tend to be nearer to the ceiling than to the floor.

    If the vent has to exit via the basement have the GC install a wall-stack-vent in an interior wall with the inlet near the bathroom ceiling.

    The conventional view serves to protect us from the painful job of thinking.

    Kinda what I thought but hoping someone smarter than me would approve. Also makeup air under door would be near floor exhaust.
