As some of my friends might know, my house was built more than 20 years ago. Its a pretty old design and there are some flaws. One thing that I miss the most is not having a bathroom fan. The importance of having bathroom fans is pretty big. It not only exhaust moist hot smelly air from the room but also bring in cool good air from the outside. There are some pretty quiet models available. I will add this to Binilslist (sort of like craigslist..lol).
