there are thousands of pictures on her w/options exactly like you've chosen. Have you looked at them?

We have no idea what the bathroom layout looks like.

don't know how the shower is being built or how you want the tile laid.

I did real marble on my floor like this w/a lot more decorative items in the room. (if you click on my name, bathroom redo, you'll see it).

all that white is a very cold looking bathroom. (and the choices you've selected too). Without knowing what else you plan on doing, it's hard to say. All your options can work just fine. 3 and 4 might need something else to break up all the cold white marble look.

option 3/4,,,you'll basically have something like this, but w/the gold. The wainscot is a nice addition. If the walls were painted an actual color, I think it would look very nice. maybe a light wood shelf, or a wood stook, a nice runner.

number two will have this look (w/the slate floor) The teak stool is trying, but it's not enough!

In mine I added a wood ceiling, some blue, plants, and decorative tile (I have th basketweave marble in the water closet) Not saying you have to do all of that, but a little warmth/contrast can be good.

You can see a glimpse of the wood ceiling in this shot. imagine if it was white, the vanity white, the window white and no black contrast. it would be a very cold looking room.

Here's one that is similar to your choices, but w/out the gold hardware. It's nice

A little too much white for me though. what do you think about doing a 'rug accent' w/your basketweave?

Now compare those similar elements to this one. (with gold!)

Look at the diff a little contrast makes. That black door, black lights/mirror. Some painted wood paneling (wainscot would be fine too) and the vintage looking chandelier. They all add interest to the cold/white marble look.

marble top, white vanity, gold hardware. just the addition of this wood mirror and accent pieces helps immensely to add a bit of warmth.

Your option 1 may look better if you went w/this type of vanity instead of white.

But if the vanity is not an option, then you could do a warmer wall color, some art, maybe some driftwood or walnut shelves, even the mirrors.

and this option might look better w/a bit more black

since you can't do the vanity, bring in the black like they show here in the trim

I like the materials in option 3 the best. I don't know how they'd look in your space and many people are uncomfortable using marble in showers, though.

These photos above are the two bathrooms we are renovating. They need to also have the walls painted. The counters have been installed. The second photo is of the smaller bathroom and it has a door going into the bath shower and toilet area .
