Hello there! I am building a house and looking for help/inspo for our master bathroom shower floor and wall tile. This link is my inspo. https://www.pinterest.com/pin/803329652265987642/

I'm searching for that color tile and shape for the walls, but unsure of the shower floor tiles. A small white hexagon seems like the obvious choice, but wondering if there are other creative suggestions or tips for sizing between the two tiles that I should be mindful of?

If it helps: the floor is a dark grey concrete. The floating vanity and free standing tub are black with white counter and basins.

Any ideas would be helpful! Thanks so much!
