We just did a complete gut renovation of our bathroom and we installed a
fan/light combo unit in the ceiling...The bathroom didn't have one
before..The plastic duct goes up thru a foot of insulation into unheated
attic and over 6 feet to the outside wall to a soffit vent..Now that is just
above zero I get a few drops of water dripping from the fan after a
shower..Is this normal and if not what did I do wrong ?? Thanks...
Given the cold temperature, it is condensing before the vent can carry out
the moisture laden air. You can probably benefit by insulating the vent
pipe a bit further or by leaving the bathroom door open a bit to vent some
of that moisture into the rest of the house.

Is the fan running when this happens?
What is the purpose of the fan anyhow? To keep the mirror from
I would leave the fan off, let the room fill with steam, which after I
opened the bathroom door, maybe a little bit at a time as I dried off,
would escape to the rest of the house, warming it and increasing its
humidity, which is usually adviseable in the winter.
No wasted heat. Instead of blowing it up the vent outside where it's
not enough to warm the outside.
I don't even have a fan. Code does not require on if you have a window. We
leave the door open a few inches and have never had a problem. I don't see
the need to barricade the bathroom just because someone is in the shower. I
do, however, have a cute butt so I can understand that others may want to
see me naked.
I used to live in an apartment with two switches in the bathroom.
One controlled the light which had an exhaust fan. The other switch
controlled a heater which had a fan to circulate the heat and keep
the heater from overheating.
Every single time a guest used my bathroom, they turned on both the
light and heater when they entered the room. When they left, they
ALWAYS turned the light off but left the heat on. It NEVER failed.
I once got tired of having to run into the bathroom to turn off the
heater. I used transparent tape to tape the switch in the "off"
position. The first person who used the bathroom tore the tape off
so that they could turn the heater on.
When they left the heat on, it was always on a day when the
temperature was 80 degrees F or warmer.
After I moved into a house with the same switches, I replaced the
heater switch with a timer so people could not leave the heat on for
more than 60 minutes. (If I had found a 15 minute timer, I would
have bought it instead.)
When I am in the kitchen, I often kick one of my cat's balls.
After I kick it, he will sometimes play with it for a few

My mother was against ever locking the bathroom door. She said people
can slip on the tile floor or even more likely, in the bathtub, and
hurt themselves falling onto the hard floor or the hard bathtub, lie
there unconscious or unable to unlock the door, and people outside
won't be able to help them. I think when she grew up** bathroom door
locks were harder or impossible to open from the outside, and even now
a lot of people don't know how to open "privacy locks". She said
closing the door ought to be enough to keep people from walking in
(and I think she would add, even if they did walk in, it wouldn't kill
**Actually, until she was 10 or more her family only had an outhouse.
I don't think anyone locks the door to real outhouses, as opposed to
I've been in a lot of homes, more than half maybe, where the bathroom
door was shut. I think that's one of the things that would bring up
my mother's repeated statement. Our bathroom doors were wide open when
no one was using them.
As are mine, but I live alone. -- I've been meaning to get in the
habit of unlocking the front door and taking the cordless phone when I
go into the unfinished, permanent-floorless attic. One time I knocked
over the ladder and had to jump down, which is harder than it sounds
because the closet shelf is in the way so I have to move my body
forward, but if I do that too much, because of the wall above the
front of the closet, I will -- get this -- break my neck**. I
didn't' break my neck, and I landed either on the ladder or between
its parts, and didn't even break my ankle.
**Third time mentioning this this week.
I wouldn't quit your day job for a new career in home construction. A fan is
required by code in almost every location in the US for two reasons: Odor
control for the toilet and moisture control fror the bath/shower. One is an
annoyance, the other is essential to keeping mold under control. Letting the
room fill with steam over the long run will at a minimum create a surface mold
problem and potentially create a problem behind the surface.
the other is essential to keeping mold under control. Letting the
open the window in the summer and open the door in the winter.
I've never had bath fans, and have never had mold problems.
Humidity is a good thing to have in the house in the winter.
Bath fans are wasteful of energy and that they are now code in many
places is an example of misguided government "help".
Bullshit yourself. Just shows how ignorance goes round and round in the
world, now aided by high-speed electronic communication networks.
I installed a vent fan in a bathroom for a client this summer, and it
was sorely needed. The bathroom was starting to grow mold on the
walls--and this was in a tiny bathroom with a large window that could be
(and was) opened to let out moisture.
The Panasonic fan I installed uses very little energy; something like 65
watts for the fan. I installed it on a timer (mechanical wind-up timer),
so it will always go off automatically. Not a huge energy waster, and
performs a very useful function.
Like someone else said here, I wouldn't be too quick to quit your day
job to go into home construction.

To me, the *plonk...* reminds me of the old man at the public hearing
that's great Dave,
yes fans are sometimes a good thing, and if your client needs one/
wants one, great.
My comment was about the code that requires a fan even when not
Someone mentioned that the code does not REQUIRE a fan if there is a
window, and that seems reasonable.
I learned the hard way not to do this.
In the winter, letting that much moisture out into my home enabled it to
condense on all the windows. And that much moisture on all the windows
led to mildew all over. Perhaps it's not as cold where you live. But
in northern MA where I live, during the winter it's typical for the dew
point to drop quite low at night.
A *little bit* of moisture in the winter is a good thing--I will take
the towel I used to dry myself off with, and hang it up in my bedroom to
let the moisture evaporate off the towel there. But not the kind of
steam you get from a hot bath or hot shower.

I"m not saying he shouldn't have a fan. And I accept the fan for odor
control, although my toilet doesn't smell bad, only my gases on
I don't believe that. I have a fan in every bathroom because none
have windows (and the've all been unplugged or put on their own
switch), but prior to living here, everywhere I lived had windows and
no fans and no one opened the window in the winter, and they and no
evidence of mold, let alone a mold problem.
In the other three seasons, people opened the windows for fresh air,
but now that people have AC, this probably applies all year long.
What I think is the case is that a few people have a mold problem so
they made a rule to remedy that by requiring a fan in every bathroom
without a window and recommending its use by everyone. That is the
kind of scattergun solution that is applied to many problems. This
is understandable with say, smallpox vaccination, or even measles
vaccination, but not here.
No fan in our bathroom - if it gets too humid I open the door, or the
window. If it gets too smelly I open the window.
Never any mold or mildew problems, and as mentioned before by others -
it helps keep the humidity up. We don't have a humidifier on our
Because fans are code doesn't mean they're always needed or even a good idea.
My first house always had mold/mildew problems, even with a fan. The fan in
our current master bathroom is in the throne room and is pitifully
underpowered to clear any humidity in the rest of the bathroom. The room is
large enough that humidity has never been a problem. The mirror doesn't even
