Given the options, I prefer the bottom right.

Top left. A backsplash is very useful!

Hard to tell from photos, but top left (yellow tones) might clash with your tile (pinkish tones).

I don't know your style or how the rest of your house looks, but I don't really like any of these as they are a bit too ornate.

Is it going against that tile or a painted wall? If it is against that tile, I actually like the darker one for some contrast ( you already have a dark finished faucet in the shower) Other wise the bottom right one with the dark faucet...

Its hard to tell...

Bottom left that says 12:51 PM.

None of the above. All of them are much too difficult to clean.

Top right, darkest one

is the bathroom large? small? what are the dimensions? can you sketch a layout? what type of floor do you have?

since the wall is tile..and you need at least a minimal backsplash then the darker one might do.. post an after photo when all done..
