Can you actually get a shower, vanity and water closet in your space? 7 1/2" x 10' might not accommodate all those elements.

Yes. The toilet will go on left side of pony wall and shower on the right. We will have a floating sink on wall opposite of them.

They will all provide a similar feel, but if you like the entire look of your inspiration picture, suggest the first tile on shower walls and second for the flooring.

Maureen… did you click on the photos? I noticed I put them in the wrong spots voting wise🤦‍♀️. So I’m not sure if you think the lighter one should go on floor or shower. Please let me know

Based on your inspiration picture, dark on walls, light on floors, but it also depends on where wall tile will be used.

The shower tile would go on back wall (wood area) and wall on right.
I’ve also provided a better picture of selection for you to see

For the shower, I'd go with the tiles at the bottom left corner. For the walls, the ones at the top. I'd prefer a bathroom dominated by bright colors, so I'd leave the darkest tiles for the floor...

I like bottom left for floor and shower floor if the make small tiles. Photo bottom right for shower walls.
