Why in the world would people use bathtubs? Seriously?! Bahahaha!

"Well for one, a broom is way more easier to lug around than a bathtub is." she said, raising her hand once more before leaning back again on the grass. "And you wouldn't get any funny glances either, but it's more the fact that brooms are easier to conceal from the muggles."

It could also do with the fact that brooms were way more wind resistant then a bathtub or...recliner. Besides, that ravenclaw dude was right. Aren't flying carpets illegal? Unless there was some new law she missed, then she totally wanted one!!
