How to paint a shower grate?

I have a shower grate that is not metal and the paint or cover is peeling off. Is there a way to repaint the grate so it looks better?

The photo should explain better what I mean.

Well done @viide such a good result, as the chrome peels off these can become a little sharp on the tootsies this is sooooo much nicer than simply replacing the centre grate insert 👍
