The read an article about a family with several young sons, and when renovating their bathroom, the mother had a trough sink built.
I’m not sure why this is so much more appealing to me than a traditional counter with two or three sinks, but it is. I love the idea of seeing a few of my kids brushing their teeth at the same time. And I love that the sink is really big — perfect for teenage girls who are helping their friends experiment with hair color.
Also, I’ve probably mentioned this before, but I’m an advocate of hooks for towels in the bathroom as compared to standard towel rods. You can fit many more towels in the same space, and kids can easily hang the towels themselves. In humid areas, they seem to dry out better this way as well.
