Tip for hot showers

No, don't start that guys!
I take hot showers, very hot showers. When I get out, the mirrors are fogged and the light fixtures and pretty much everything in the bathroom is dripping wet. I've even had water dripping from the ceiling on a few occasions. When i open the doors to the master bedroom, it heats up that room and it takes a while for the a/c to catch up, especially when the bedroom door is closed.
I read a tip somewhere and didn't think it would work, but it was worth a try. It works great. Just turn on the exhaust fan and leave the door to the smaller toilet room open There no fogged mirrors, no wet fixtures and the bathroom is only slightly warmer than normal. I mean very slightly warmer. I would never have thought a fart fan would move enough air to clear an entire master bathroom.
Remember, don't start that guys!!!
Chas.

We are having our master shower rebuilt. The tile guy told me to be sure to turn on our exhaust fan when showering because more moisture builds up than people realize. We even had a few spots of mold behind a couple of tiles.
The exhaust fans make a huge difference.

My fart fan surely can clear the whole house, not just master bedroom
I'm sorry, couldn't resist. Good post and funny too, I spilled some coffee as I thought about the fan

Agreed. When we did our master bath remodel, we over-engineered any parts that would be helpful in removing water - because of the risk that mold can destroy a house so easily. Drain pipes were a bit bigger than normal, an additional floor drain was added, and three exhaust fans were included.
Three? Yes, three. One for the 'fart fan' as Charles so gracefully referred to it. One for inside the shower room (we glassed in the end of the bathroom and made a big 10" x 16' room with a huge tub and two ceiling-mount rainshower heads). And, since we relocated our washer & dryer into the attached walk-in closet, we put another fan in there to keep the humidity levels low where we hang our clothes. All three fans have motion sensors, so they activate when you enter the room. The closet and shower room fans also have humidity sensors, so they activate if the humidity level creeps up just a little bit.
From a volume perspective, any one of the three fans would be sufficient to manage the size rooms we have, but like I said, humidity was a risk area we wanted no part of, so we built in redundancy and overcapacity, for not that much $$.

As an HVAC guy, I can tell you that bathroom exhaust fans are actually designed in a house to do just that, remove the moisture. The smell removal is actually an added benefit.

Do you also have conditioned fresh air make-up, or do you draw the house negative?

I've done two things related:
Changed the light switches for the exhaust fans to timers. There are buttons for 'off', 5/10/15/30 minutes.
When I finally replaced the builder grade single pane windows throughout the house, I replaced the fixed picture window in the bathroom with a sliding one. So (if it's not 100 degrees out), I'll open that window, and another in the bedroom, creating an awesome draft that carries the steam away with it :-)

Always have the fan running when showering.

We have two incoming ducts into the room. If all three exhaust fans would be running at once, it would be a negative draw, but (a) it is rare that all three are going simultaneously, and (b) the bedroom is adjacent with its own robust supply of incoming air.

Wait, that's not what those fans are for? I always thought they were for removing the added heat and moisture from showering, though I do also use them when I sit on the porcelain throne...

I have always used the exhaust fan in the main bathroom area to reduce the moisture level, and the fan in the smaller room to reduce odor. Now, there is something new to help with the latter issue

When we built our retirement home, I had an exhaust fan built directly above the shower. No humidity in our bathroom.
