Can we see th space and also a to scale floor plan. I am not sure which are which and what is the flower pic ?IMO simple 12 x24 tile on floors and shower walls is always my go to. I think busy tiles are the first thing to drive youcrazy down the road. I really don’t ;ole too many grout lines in the shower or on the floor of a bathroom.Free standing tubs require large spaces to look and function welll at least 12” all around the tub for cleaning and the bigger that spacing is the better . Wall color is the last choice you need to make so wait for all the other elemnts to be in place before that.

Thank you. My space is approximately 9 x 8 or 72 square feet.
