Toilet FunPlay it safe with fixtures: Savvy parents choose classic colors and designs that will stand the test of time for toilets, countertops and vanities. If one of the kids using the room is very young, and there's room for a double sink, consider a two-level countertop that puts one sink in reach for the tinier tot. Make sure your ultimate kids' bathroom also has safe stepstools so that youngsters can easily reach what they need.
Have fun with accessories: Whether you have a preschooler hooked on Dora the Explorer or an older child obsessed with anime heroes, today's gotta-have-it icon will be passé before you know it. Indulge your child's taste for cartoon characters and other themes with fun and funky shower curtains, rugs, linens, wastebaskets and other accessories. These items add a lot of design fun, but are easy to swap out for the next "flavor of the month."
