Seems like a classic combo! Assuming the whites of the subway tiles and of the floor are complimentary I think your bathroom will be lovely. A round or oval mirror would be a nice contrast to the very angular and faceted aspects of the rest of the features :)

Alana, you've posted this in the Laundry Forum, not the Bath Forum. The BF is super active, too, so you might want to try over there where the experts hang out. There is also a Tile Forum, IIRC, with a lot of professional tile setters answering questions, but I have never visited. Good luck with your project.

I can help you with the big fluffy snow white bath towels your putting in this bath..lol
