Here is another shot of the floor from the kitchen area (more light) to give you a better sense of it. Thanks in advance!

large format tiles are great for limited grout lines

... the lighter the better in a room with no natural light.

The wall tile needs to go - we have plumbing issue and it’s that terrible, marble looking surround from the 70s. Looking for new.

Sorry for your plumbing issues. Use lightest color in floor tile for the wall tile. Solid countertop in color from floor tile.

I'm guessing a white would be too much? Also, for the bath surround, solid or would a slight pattern work (something that resembles light veining, etc.)? Not exactly, but Something like this.
