I totally understand your concerns about maintaining congruity with the era of the house. My personal feeling is the the mix of old and new is what makes design interesting. I'm not a fan of walking into say an all modern room in a vintage home. It's jarring. But intentionally integrating a modern element into a more traditional space can be the spark that "makes" it. So, for your bathroom, the larger hex can be a "riff" on the classic tile - that updates it while playing homage to the house's era. At the same time, the use of a solid blue on the floor is already a more modern use of the material. So you could go with a smaller blue hex rather than the larger. I would choose your grout very carefully. I personally don't like a ton of contrast between the tile color and the grout. It just looks really busy to my eye. I also am imminently practical and would never put white grout on a floor. Something in the medium gray range would probably work best but I would have your tile installer make you up a couple sample boards once you get to that point. Smaller hex in a solid color: Grout similar to tile color:

Jane, thank you for the input. I should have posed my question a bit clearer. I need help with metal for lighting, faucets, etc. I'm looking for suggestions for the entire (overall) look of the bathroom. At first I was going with polished nickel, but the faucet I want to use (Delta/trinsic) does not come in polished nickel. The light fixtures I Iike only come in polished nickel and not chrome. It's just so frustrating. I thought I could do mixed metals, but unsure of that too. I read a number of folks say don't mix polished nickel and chrome. I was thinking matte black, but nervous. My husband won't go for brass (after posing my above question), though I agree, it would be interesting. Thank you again, and if you have any other thoughts, I'd greatly appreciate them. The double vanity is 80" (white), there will be a free standing tub (white), with separate shower in white subway tiles, the quartz counter tops are a medium gray, dark slate floors, and lastly white walls. It's so hard for me to use my imagination and picture different metals in the space.

I would do a charcoal grout, just slightly darker than the tile. Looks like the same grout used on the wall tile in the photo would work!

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
