Ripa House
Kid's bathroom. Navy cabinet, white countertop. Then get a navy and white striped shower curtain. Or a fun design with blue in it. You can leave the floor and place a rug down or you can replace the floor, of course. But I think painting the cabinet, replacing the countertop and getting new shower curtain/rug/accessories, would make a big difference in getting the bathroom more "kid friendly".
Another picture of the same idea. I also like the gray/ivory color scheme. Very calming, but modern.
