No! not a good idea to vent a bath fan into a crawl space. It could cause moisture accumulation problems. but, there is no reason you can't just run the pipe thru the crawl space to an exterior wall. use rigid metal pipe to cut down on drag. you might need a larger than normal fan to get enough air flow.

(I'm not sure why you would have problem with sewer gas in a bath vent fan unless you do some really "creative" plumbing!)

: Want to install a bathroom in our Victorian home built
: in 1868. The bathroom will be on the main floor of our
: 2 story bed and breakfast. It will be installed on an interior wall, can not go out through the wall and can not go up because of rooms upstairs. The only thing that makes sense is to vent down with ridged pipe into
: large crawl space.
: Any problem with that.
