Condensation and ice on the windows resulting in mold on the main level, mold on items stored in the basement.

At first glance, that sounds more like a basement moisture problem than humidity from showers, etc.

Just out of curiosity, where do you live and what humidity levels are you seeing that you need a humidifier? We had a central fresh air system/dehumidifier installed when we finished our basement last year. I try to keep the relative humidity between 35-40% in the winter and under 50% in the summer here in Wisconsin.

Maybe it's a climate/geography issue - I'm not really familiar with Wisconsin's climate, but here in the midwest (PA, OH, KY, etc.) one generally needs a humifier to get the humidity to the recommended 40% to 60% range in the winter. Keeping the humidity toward the 60% range increases comfort and decreases heating costs in the winter (because cooler temperatures are more comfortable with higher humidity). I've not had any condensation issues at 60% humidity.
