Tiny House Moisture Control

In planning my tiny house, another issue I am facing is how to deal with moisture control. The biggest moisture source will be hot showers, but cooking (especially with a propane stove) can also add moisture to the air in the house. Not knowing where my final destination/climate will be, I need to make precautions to avoid future mold/mildew problems.

I plan to get as much light and air into the house as possible—to make living in such a small space more sustainable for me—so it’s really only the winter in which I can see having a problem. I don’t see myself enjoying exiting a hot shower to an open window with freezing cod air blowing in.

An obvious option is to install an exhaust fan in the bathroom, to be used whenever showering. This is fine except for the added electricity usage (not a huge deal now, but later on I do plan to convert the house for off-grid use), and it requires another hole in an exterior wall, thus more work to install, and a less air-tight, less efficient envelope.

How do you control moisture in your tiny house?

Do you use an exhaust fan in the bathroom or kitchen? What other options are there for moisture control and ventilation, especially during very hot or cold weather?

Any recommendations for a very efficient, quiet exhaust fan?
