Have you already ordered swatches of the wallpapers?

I have swatches of both

The second one is a lot more interesting with the floor tile.

If it's a powder room I'd choose something with a bolder color. Maybe the dark charcoal or the gray in the floor tile. And I'm not sure the second pattern works with the floor tile pattern and the shower tile pattern.

The shower tile and new tile both look gray in photos, not beige, so the color balance isn't quite right. If you have floor tile sample, try including a piece of white paper, the swatches, sample tile and shower tile in the same photo.

The second paper (herringbone) looks awesome with that tile. A very relaxing but lovely vibe.
