I tend to keep bathroom tiles simple I use 12 x24 porcelain for both bathroom floors and shower walls a smaller matching tile for shower floor and then if an accent is wanted a nice tile in a vertical strip not cnetered on the shower wall and that same tile for the backsplash IMO simple materials mean logevity in spaces . Ilike that tile but not in as much as you are planning I think one of those "what was I thinking" monets will happen very quickly.

That seems to be an unusual size tile for a shower floor. The specs on the website mention "specific installation requirements" for use in the shower. Just my two cents, but I think such a bossy tile on the floor and shower floor will be a bit frantic and jarring to the eye. If you go through with it, then make everything else extremely plain and minimalist.
