How successful is it to paint shower tiles?
My shower tiles are original to my house, built in 1979. I'm putting in tile flooring (currently it's sheet vinyl), painting the walls and mirror frame and putting in a vanity (previously had only a sink attached to the wall) which I'm painting to match the mirror frame -- both a soft teal-like color. It's a VERY small bathroom. The paint I've chosen is a light gray with very warm undertones and my current 4 x 4 shower tiles are beige. I chose the warm graybecause it will look OK with the tiles. BUT I'd rather have a grayish tile but don't want to spend the money to have new tiles installed. I've read online about painting the tiles but I'm confused. One recommendation was a Rustoleum product meant for tiles, but it only comes in 3 colors and gray isn't among them. I've seen where others have used regular paint. Some have suggested lightly sanding the tiles, then applying Kilz, then paint. One photo showed the paint peeling after a while. I do NOT want to re-do this job if I decide to do it. Suggestions? (The photo is not of my tiles, but they're this kind -- very shiny surface.)
