If you want the wall and floor tiles to be the hero in your bathroom I recommend you keep the vanity very simple. The white cabinet you have will be least obtrusive with a 'white' top. I love the elegance of stone and man-made stone is generally more durable. Check out Caesarstone Organic White or Frosty Carina. Although Frosty Carina has more pattern than Organic White, it's quite discrete so shouldn't compete with pattern on the tiles. If the tiles are charcoal or a dark brown/grey then either should work. Love to see a photograph when it's finished, whatever you decide.

It could be horsehair plaster. Plaster used to be re-inforced with horsehair, but it looks more like fibreglass strands. Horsehair matched the period of the original home, whereas fibreglass doesn't. Best of luck, Dr Retro of Dr Retro House Calls

Form me the larger one is more functional allowing 2 people to stand either side and use the sink. But really 1200 could do either.
