Yes, painting bathroom tiles is possible as long as you have the correct paint. For bathroom tiles, you’ll need specific paint that’s moisture-resistant and easy to clean.
You’ll need to properly prepare the tiles by sanding and priming before applying at least two coats of paint. Painted bathroom tiles won’t have quite the same high-quality finish as original tiles, and they can crack and flake over time – so you’ll need to factor in maintenance in the future too.
