No white after Labor Day is a hard and fast southern rule as well!

If it goes with the overall design, yes. I have a hand painted Mexican Talavera sink and a white toilet. It is the same design as the photo, but it is a wall hung sink. I have Talavera tile in my shower.

You can make it work if it fits the overall design. What are the other elements in the room? Flooring color and material? Vanity color and style?

Thanks for the inspirations. Think I’ll try the black sink with a Carrara marble counter top, then get a white toilet with a black seat. Probably some black and white tiles around the toilet in a rug- like pattern. I’ll also have a wood floor in the rest of the powder room and a wood on the front of the sink counter to hide the plumbing.

I guess I thought that the toilet was to be seen and not heard but it seems like you're making it the centerpiece of your bathroom -- which seems odd to me. Also, I understand that vessel sinks make bathroom cleaning hard as one can't just push countertop crud into the sink.

I say go for it! But personally I would keep the toilet all one color, otherwise you're just drawing attention to it

Forget the black seat just let each element stand on iys own. I don’t fin cleaning a vessel sink all that bad,

Agree with the others - no black seat - don't draw attention to the toilet.

I personally selected an integrated sink so that I would have no seams to attempt to keep clean.

I thought about vessel sinks (love the look) but in the end decided it doesn't fit my lifestyle. I am too fussy and have too little time to spend trying to clean out the cracks and crevices.

Yes, one color only for the toilet. And one type of material for the flooring. Either wood or tile is fine for a powder room, but it's not big enough for both.
