Hi there, most hardware store sell paint specifically for tiles and it’s all about the prep work you need to do before painting. Here’s a great video that will show you how to paint bathroom tiles.- https://www.youtube.com/watch?v=zYkCuIAJca8&t=114s
I covered mine with beadboard. Use a ton of construction adhesive.
Here are some ideas! https://www.pinterest.com/search/pins/?q=How%20do%20you%20change%20this%201950%27s%20tile%3F&rs=typed&term_meta=How%7Ctyped&term_meta=do%7Ctyped&term_meta=you%7Ctyped&term_meta=change%7Ctyped&term_meta=this%7Ctyped&term_meta=1950%27s%7Ctyped&term_meta=tile%3F%7Ctyped
Hi! All good suggestions. If you really hate it, then it would be worth the time and trouble of replacing it. I think pink bathrooms get a bad rap because there is just so much of it. Even the floor! I have personally used the Rustoleum kit to redo a sink and the stuff is great. I actually found it for less than $25 on Amazon, and didn't even use half of it. It does have a strong odor, so you need good ventilation while using it. But, after following directions, I can tell you that it dries hard and durable. Good luck!
