Hi Faaiza, here's a lovely guide that will show you how to repaint your bathroom accessories - https://www.youtube.com/watch?v=3VoauF4IfG4

Hello are your bathroom accessories ceramic or metal? That might dictate exactly which paint we recommend. For any paint job on metal I highly suggest Rustoleum universal paint products. The ease of application quality of paint and depth of color and sheen is phenomenal. I painted an outdoor mesh patio set in this paint holds up and all kinds of abuse and weather elements.

Rustoleum has a number of spray paints and they are excellent. Follow the directions on the can and plan to do two or three thin coats rather than just one thick one and you'll be rewarded with a great outcome.
