The bathroom is an important part of the house. Some adults place some vain decorations and accessories in it but if we are taking about decorating kid's bathroom, it is a different story. You have to keep things simple yet fun so that your kids will enjoy bathing and cleaning themselves. You can still accessorize the bathroom but you have to consider the safety of the kid's, too.
It doesn't mean that just because you have a theme that you will really fill the bathroom with items that jive to the theme. Use it subtly so that the bathroom will not look too busy and crowded. If you already have lots of accessories and items in that particular theme, you can just paint the walls with a solid color that still matches the theme.
Cove lighting creates a gap between the wall and the finely done tile mosaic wall making it more appealing to the human eyes. Here, the bathtub is highlighted by the natural light it receives coming from the window. The designer wants to project a cool ocean-like atmosphere in the room by using tiles in shades of blue. The idea is to create a soothing and relaxing feel of the water.
