What are we looking at? The grey wood look is the bathroom floor option? I am personally not a fan of grey color "wood" of any type. I think it's a dreadful trend that hopefully will soon die.

Where are the white rectangle and marble-look going?

I love your cabinet, I'm going with something similar in my master.

I think the blue will look nice

The other option is this :

The white is the countertop- it’s silestone Ariel

This tile here is 12x24 a subtle white- herringbone floor and then the shower walls.

my he shower floor and niche can be done in a pebble stone

The cabinet color is beautiful. The countertop is also. I would not go with the faux wood floor. It would date quickly.

I do like that tile better than the wood look. I'm not sure about the pebble floor though. Do you have a sample of that? Those are usually brown tones and you've got more grey and blue in your choice here. I think those pebbles can also be a pain to maintain if they're not installed very skillfully. Too much grout.
