Thanks for the suggestions, all. I spent the morning at three different local tile showrooms, collecting samples. We'll see if anything works. It's been a challenge to find a solid that coordinates, as the colors of the calacatta look tile are hard to pin down. I may have found a warm white field tile that would work, now I just need to decide how I feel about a white field tile for the floor. Just like ILoveRed, I also liked this tile because it was a nice mix of warm and cool colors. The tile kayca posted is beautiful - I think I recognize it from another recommendation I got somewhere, now I just need to see if anyone carries it locally. We're trying to stay away from just using a smaller tile for a few reasons. It's a fairly large space, so I'm concerned a small tile might look busy and out of proportion. The house also leans more contemporary, so while I love the marble, we're looking to balance it's more traditional look with a larger more modern size. And finally, we really don't want to have to worry about having lots of grout to clean. I believe the Vallelunga is probably fine for some, and if it was already in a house I bought I would probably add rugs, use slippers, and live with it just fine. Since I'm starting from scatch, though, it seems like I ought to be able to find a solution that doesn't require all that.

I think a lot of people use larger tiles (e.g., 12 x 24) cut down for herringbone. That said, I'm going for the same effect, and I found this one: https://www.flooranddecor.com/porcelain-tile/dimarmi-bianco-stone-look-porcelain-tile-100434638.html I didn't want real marble because this will be the laundry/mudroom that the dog will run through when she comes in the doggie door. I made an attempt to lay it out herringbone-style on the floor of the store to see how it would look: Here is my inspiration, but this is real marble: Good luck!

I like plain 12 x24 porcelian tile for the main bathroom floor and the shower walls. Not sure what you mean by pony wall and where that will be .If you post a floor plan you will get much better help. an 8’ shower is IMO too big to ever warm up in the time of a regular shower. What is the wood look tile for? Where are you planning the accent tile to be? I need to see a to scale floor plan with maybe on just the fllor plan and the other with what you are planning.Mark all windows droorways and the plumbing at least for the toilet unless you are planning on moving that , which BTW is expensive . Mark all measurements clearly and I suggest you use graph paper it makes scale easier to do. As for all the tiles you have posted please label them as to where each will go. What I see of the bedroom looks very rustic , is that the look you want for the bathroom, maybe post pictures of the bedroom since IMO the 2 spaces should be in the same general style.

You'll need to look away from the big box stores if you want specialty tile that looks really good. Tilebar has a lot of those tiles, but some seem to be a little better quality than HD. (and some tiles are used by both places) I did a bath remodel for my neighbor and they wanted to use the Bella tiles on the back wall. I used the 3x12 subways in a stacked pattern on the other walls https://www.tilebar.com/bella-picasso-blanco-8x8-porcelain-tile.html I love the Bella Tate in the soft pinks and golds. w/rose gold hardware, a soft wood vanity, and this gorgeous pink tile done in a herringbone, (below some other floor tiles) I think it would look stunning. Not into pink? then do the same thing in any of the other 20 diff colors! https://www.tilebar.com/collection/tile-mosaic-collections/bella.html https://www.tilebar.com/catalogsearch/result/?q=+morrocan+tile if you want authentic, look at Zellige tiles or try CleTile. they were used here on this shower tile Or, Fireclay tile has the moroccan look down pat. this is Justina Blakeneys bathroom this is my own shower. I used black/white cement tiles for my 'plant wall', and black marble for the shower floor this is a similar style done w/a smaller shower. You will get a ton more choices of colors and pattern if you go w/encaustic tiles. tilebar has these Sasha Hex tiles in this blue green shade that works w/your first tile https://www.tilebar.com/sasha-hex-blue-green-6-porcelain-hexagon-tile.html you could use it outside the shower on the floor or try something like this: https://www.tilebar.com/portmore-aqua-4x4-glazed-ceramic-tile
