Use the bright, vivid colors of the coral reef and its inhabitants to bring your fish bathroom to life. Choose colors based on tropical fish, and use plenty of clean blue paint to set the tropical reef mood. If you are handy with a paintbrush, add a mural featuring clown fish, lion fish and other bright species. If you lack artistic skill, you can add a tropical fish border using wallpaper or framed artwork instead. Accent the room with toothbrush holders and soap dispensers in the shape of tropical fish.
Choose cartoon-like fish and playful graphics for a kid-friendly fish bathroom. Look for whimsical artwork, a fishy shower curtain and accents like fish-shaped drawer pulls to bring your room to life. If the bathroom is being designed for kids, choose fish accents that are easy to change, like towels, framed art prints and fish-themed rugs. When your child outgrows the theme, redecorating the room will be as simple as replacing the accessories.
Embrace the world of freshwater fish and sport fishing by creating a fisherman's paradise in your bathroom. Look for bass and other freshwater fish-themed shower curtains and artwork, and choose natural shades of green, oyster and brown to fit in with the fishy color scheme. Showcase images of your own boat or fishing expeditions, or use pages from vintage camping, fishing and cooking guides as wallpaper. Pre-1950's books about camping and fishing can yield a wonderful selection of frameable graphics and illustrations. If you have the room, place vintage rods and reels in an umbrella stand, or mount them on the wall above the tub and shower enclosure.
Use real fishnets and other authentic touches to add extra interest to your bathroom. Display fancy flies or leads on a shelf, or look for charts or posters featuring colorful fish to add a special touch. Keep a small live fish on a shelf in the bathroom if you have the room and an unbreakable bowl for it to swim in.
