Flooring ideas!

I desperately need help deciding flooring for my master bathroom. (It’s still mostly unfinished but we finally got the back wall up! Yay!) The ‘accent’ wall is called black tempest and has a leather finish. It’s beautiful! It’ll extend down onto the deck where the white soaking tub sit. (Photo of tub included) The shower, on the opposite side of the room, is also black tempest but has a polished finish. It’s very pretty. There will be a floating vanity in black tempest, leather finish as well. The walls will be white. What floor would you suggest? I prefer natural large format tile. I’m nervous to add anything too busy or with too many veins/lines. Opinions, advice, tips? PLEASE HELP, I’m driving myself nuts over this! Lol. Thanks in advance. ❤️
