As in bedrooms, textiles do the lion's share of the work in a bathroom's décor. Work with your kids to find a color or design theme that you both enjoy, and then decide how you want to build it. Shower curtains come in lots of different designs – from solids to stripes to patterns and themes. Like a bedspread in a bedroom, the shower curtain can often be the focal point of a bathroom. Once you choose that, you can pick coordinating towels and bathmats to round out the look.
