Moody Storm

This doesn't look like a color that will pull your room together. Too much blue or violet.

I have to ask...how did you end up with the counters and the tiles?

The color sample under the window is SW Grayish, too light. Another color maybe-SW Essential Shade?

I suggest the cream or niveous BM paint color (see middle of color chart) and a valance with suzani fabric from P Kaufman ( see pic) in style in photo.

This type of valance: I'll post separately

Valance style

Then pull colors from valance fabric to pull room together. It'll look like you planned the room from the beginning.

Try Slice Cucumber by Behr paints. If you like this color, I'm sure you could find something comparable in the SW line. I'm just more familiar with Behr's website.

Can you find a shower curtain that will break up the two areas?

Fig shower curtain from RH. Break up the line of sight between the shower tiles and the counter.

Zen, Top is Moody Storm. Also looking at HGTV SW Essential Shade. Is this the direction you are talking about?

When testing a paint sample, paint the sample on a large WHITE piece of cardboard. Your current wall color will distort the sample color.

I agree, you need a darker shade. All of your finishes are mid tones.

What about a warm Gray paint, and a white waffle weave spa shower curtain?

I think you need a dark color. Maybe a dark gray with a blue undertone.

Darker than the 2 you colors you have mentioned...

Mmmmm I think keeping walls in a lighter color would be best otherwise the bright countertop may stick out even more. I'll have to think of a color...

Make a stink at the store, they may have a remnant that works that won't cost you anything or not too much more.

Yes the shower curtain will help tremendously

Can you share, what did happen? Did you purchase the home like this? How can you have those two beautiful vanity tops with such a different floor and shower choice? Love the vanity granite. If you have to live with it, I would put up a shower curtain for now to camouflage the shower, but your flooring is still not the right tone :(
Maybe down the road you can change things to match.

Color Zen, I have some left over Behr Polished Stone and tried that. It is definitely the right depth. I'm trying to decide if I need a different undertone. What do you think?
