How can I paint over pepto bismol pink tiles?

Have you looked into Rustoleum Tub and Tile Paint? It is made to adhere to glassy tile surfaces. Also, I would not paint over the wallpaper especially in a bathroom because of moisture, it will buckle and peel under the paint. You really should remove it.

I KNOW A GOOD ANSWER TO THIS!!! I'm so excited! Alcohol ink!!! I've recently learned how to do this and I'm addicted. The only issue will be that you can't lay the tiles down but it really won't matter because there are techniques such as sponge blotting or other such things.

Below are some tiles I painted to have a marbled look. They will be coasters as soon as I add the cork to the back. You can blow the ink around using a straw or a can of air normally used for cleaning a keyboard.

Wow! Love that marbled effect!

As long as they are not constantly exposed to water like the ones around the tub would have been, a high-adhesion primer should work, as long as you let the paint cure. I see you are in Canada, the newer low VOC paints, do not seem as durable to me, so it could be scratched if it is a full wall.

I sprayed a laminate cottage countertop about 20 years ago with Krylon Fusion spray paint. The ceramic shiny backsplash looked like bathroom tile, with ugly ovals and pink white and black motifs. I sprayed the tile too with a couple of light coats of the Fusion paint, and it never came off. All I did was clean it really well with soapy, vinegary water and steel wool. It was sooo much better! You just have to watch for overspray, and keep away from gas pilot lights. Do you have an inconspicuous spot or any extra tiles you can try it on?

Hi, I had ugly gold tiles in a powder room that I primed with kilz primer and then painted 2 white coats with satin latex paint. So far so good. Just be careful not to scratch with tools as my plumber did. I repainted over the scratch.

Thanks for the 'tried and true' advice. Drat! did not save an old tile as I was not on site when the wall came down. I will test it behind the door and keep my fingers crossed. As to the low VOC Canadian paints - HA! I had to vacate the house while they painted as the 'fish flake' odour gave me, and the painter, a pounding headache as we painted on a day when we could not open any windows.

It is best to use paint specific to the task.
