Removing humidity while showering

Our motor home has the toilet next to the shower its in its own separate room. I went into a home improvement store and bought 2 cold air return vents. Next I cut a hole through the wall next to the shower up close to the sealing and installed the 2 vents. When we take showers I turn on the exhaust fan in the toilet and close the door and block the bottom of the door there's is about a 2" gap there, with a shirt from the dirty clothes then open the bathroom window. With the exhaust fan running and the bottom of the door blocked all the air is pulled through the vent next to the shower. The mirror no longer gets fogged up even if its cold outside. The other thing that I did was to make a wedge out of a stiff plastic sheet that I mounted to the vent next to the shower. It touches the top of shower wall and the bottom of the vent so all air is pulled from shower. With out the wedge half of the vent is below the shower wall. You don't need to make the wedge But I like to tinker with things trying to make them better.

We replaced the cheesy oem vent with a Fantastic Vent. That does the job for us.

x 2 on the Fantastic fan. Great unit ! You can get a controller that works on humidity levels as well as temperature. Can also set fan to close lid in event of rain, so gives you ventilation all day long.

Chamois or squeegee the water off the shower walls helps tremendously.

My frustration is that I have a divided bath. The shower is across the hall from the toilet room which has the exhaust ceiling fan.

Wow, Holes cut into the walls for vents? I'm curious as to how bad the humidity originally was?

I just use the cheesy tiny OEM fan that came with the motorhome.

Sounds mighty serious water vapor. I just turn on both my fans and crack a window just a bit. Of course we only take COLD showers HAHAHAHAH.

yep, gotta crack a window.. I was doing some work in the back bathroom and had the fantastic fan going when all of a sudden, the dreaded sewer smell attacked me.. I also had the vent open in the half bath.. come to find out I was pulling down sewer gas from the roof vent pipe right down into the half bath via the roof vent. then I found I was also getting sewer gas down the side of the vent pipe right into the bathroom cabinet.. Pipe was not sealed to the roof.. IT IS NOW. no more sewer smell. and I opened windows.. If you ever want to have frosted glass window in the bathroom I used a product from Rustoleum called Frost Glass.. worked awesome.
