looks like you have plenty of color with the tile....I would stick with white and use glass shelves. A sink with two front legs would be more 40s iconic but then you lack storage. Ikea makes great skinny wall cupboards for under a hundred dollars and they provide great storage and virtually disappear....

Thank you! Yes joelegnater I believe a sink with two front legs was the original sink based on what the other units in the building have. It does lack storage. I was debating between a white vanity or a brown/black vanity from IKEA (mainly bc I already have a tall cabinet in black/brown that I used in another bathroom, pictured below). I'm worried it might look too harsh against the tile.

Are the tub fixtures original? Can't get a great look at them but it looks like they might be, or at least in the original style. I would look for sink fixtures that have the same vibe.

Yes they are the original fixtures. I was thinking of buying an IKEA vanity and replacing the knobs with Glass ones.
