I am putting in a bathroom in my basement and know I need to vent the
fan. I plan on running the vent between the joists, but I'll need to
jog around the i-beam. is it okay to use flexible dryer-vent type
pipe to come down and then back up to get around the structural beam?
Essentially it would look lik ~~~~U~~~~~~ where the U is the flexible
vent pipe going underneath the beam? Other suggestions?

Thanks,

That U might pose a problem if you vent it out the attic roof. Think
P-trap. Even shower mist could condensate on the inner walls of the pipe
and fill the U.

I'm not planning to put a shower in the basement bath, just a toilet
and sink. THerefore I'm not really worried about the condensation or
reduced air flow since I'm only putting the fan in to meet code. I
know that what I'm proposing is less than ideal, and if a significant
amount of moisture really needed to be exhausted then I'd probably
have planned it differently, but as it is, I just want to pass code.

Why not go the other way?

The other way is the garage.

Which brings to mind the question: Why are lavatories required to have a
vent?

To remove smells instead of having them go into the whole house and if
there is a bath/shower, to remove excess moisture. I think in most
places, the vent can either be a fan or a window, though I would
always want the fan.

Slightly off-topic, but related. Do I need a vent for a utility sink
in the basement? Is it recommended/required to install the utility
sink inside the bathroom that has a fan-powered vent?

I think you need a sewer vent pipe, which is an entirely different
beast.
