Any color at all will go with your white. What color is a featured color in other rooms? Do you stick to mostly neutrals, or do you have bold or pastel or grayed accents elsewhere? I would paint the vanity according to your house’s decorating scheme and do a non-white counter, then use those colors in art and towels in the room.

@Sharon Perkins Really great result and such a difference for making the counter look perfect! Love the new mirror, repositioned medicine cabinet & wall color! Thanks for coming back to show us. And, your lovely son-in-law - is he good with the changes after seeing how good it looks?

I think the cabinet's wrong for the room. I like the cabinet better turned sideways, but that creates an odd empty space beside the toilet. Could you find a wider-but-shallow china hutch at a thrift store? Preferably without glass doors. They're easy to find these days. Something that would fill that back wall. Consider painting it white to match the vanity ... or go with a color. Use dark hardware to match your faucet. Then fill it with pretty towels (not white -- bring in some color), small plants and such. With that done, add a large piece of artwork over the toilet and a pretty floor mat (those big tiles aren't doing much for the room, but taking them out would be real money, and it'd turn into a snowball project).

If you don't change the tile I don't see the point in trying to change the wall color. What is there is a good match for the tile. The vanity top isn't great, but I don't think a white-white would be an improvement because the tile is a very warm color. The white toilet really stands out - not in a good way. You could always look at remnants in slab yards to see if there is something else you would like better for a vanity top. There may be something available in a big box store off the shelf that would work if the vanity is a standard size. I think the wood vanity works with the tile. Since this is the only bathroom I would just leave it alone as any change is going to be quite disruptive, and without changing the tile, not a big change.
