Can I use any other paint on my bathroom tiles other than a secific tile paint

As with your other post, I need to know what tile material you have. The surface has to be perfectly cleaned and primed with a primer designed to hold on this material. Your top coat will be determined by what the prime claims it will hold. I have never done a job like this because I have yet to see a finished job that is accetable. It does not come out looking like new.

Marine grade paint for top coat. You can look into pool paint as well. See your local paint store for these products. MDX primer should work.
