Can you show us a pic of the whole room? No matter if it's torn apart

yeah, I don't think anybody makes tiny tiles for such a big pattern. pick white or black and move on, or see if the same tiles can be treated to be anti-slip.

or I guess you could try to find a delicate pattern that would coordinate...

So the tile you want is available at Home Depot.

I don't think you are getting very good advice here. Don't mix this tile with a marbled hex tile, and I recommend you purchase a sample tile of this flooring and a sample tile of the white 4x12 tile to see if their colors pair well. My guess is the white wall tile will really highlight the creaminess of this floor tile. I love the floor tile. Don't compete with it by adding other patterns to the palette. Using black and creams are probably your best bet. If you want an eclectic vibe, then bring in morr patterns is an option but it is harder to do well.

subway white would be my choice

Hi Jonapa3

I recommend doing the shower floor with a 1x1 or 2x2 white mat tile.
The floor tile has plenty pattern it , and the small square for shower floor would repeat the square in the floor tile centre.
Just make sure all the whites go well together.
