There is a huge variety of porcelain and ceramic tiles. And many different whites. I would highly recommend getting a ton of sample tiles and laying them out near your marble subway tile. That way you can find a tile that looks just right for you. I think overall mixing the marble and the ceramic tile will look lovely, as long as you carefully choose a white that compliments the marble. Not sure if you're tiling the floor, but if you are, perhaps you could do your white ceramic on the floor as well and do a trim around the room in the marble. I think this might help tie the tiles together so that the marble looks like a special feature you've added in as an accent.

Thank you so much to everyone for the advice. That's what I was afraid of...too many elements. It's an older home and I want to keep the "charm" of an older space. I was planning to use honed black granite for the counter tops. It's going to primarily function as a kid's bathroom. I am using the antique brick in a few other areas of the house. I recognize the riskiness here, but was hoping it would come across with a charm that is original to the home. The antique brick blends better with the other elements in the home than the carrara does. I'm still not sure how to bring it all together. I know that the white porcelain is timeless. Will the carrara/black and white bath be outdated, considering it's been such a popular choice the last couple of years? What about the subway tiles?

Thank you pllog! According to my admittedly limited research, white subway tiles were primarily what was used during 1913 (not colored tiles just yet), or else white or cream-colored wainscoting. I know the colorful tile was used on fireplace faces though, as is the case on ours - but I think the whole sterile kitchen and bathroom look was going on in 1913 (?). I know my house originally had it cause not only is 2x6 white subway tile in the original bathroom upstairs, but the previous owners, who I am friends with, remember it having been in the house at one time. The previous owner now in her 80's moved in with her parents in the '40's when she was a teenager. There was only one family that lived in the house before them, which is kind of neat to know. I'd love to find out more about them someday if possible. All that said, if I had the time further to obsess (I'm already taking LOADS of time away from my kids to obsess over every detail that I am already!), and the eye/confidence/creativity, or a designer, and the money, I'd do something much more fun and much more "me" in a NY heartbeat. But alas, I don't. Maybe someday. The following cut/paste link is to absolutely inspiring backsplashes, which you'd probably love: http://finishedbacksplashes2.blogspot.com/ It would be impossible for me to do if the tile were to get up to $100/SF. How did you come up w/ that calculation? Oh dear - I'd better do the math again! I was told that by going to a fabricator with big machinery, it wouldn't take that long at all for a back splash my size - but that was just one person who said that; he could have been wrong. One consideration for a backup plan for me has been white or off-white minibrick. I think with a non-matching grout - e.g. a noncommittal but darker sand color (sand having both tan and grey in it?), all those little lines would be more interesting w/ the stainless than the bigger subway tile (or, maybe that would also be the case w/ standard 2x6 tile w/ darker grout?). I wish I could find the link I've lost to ceramic minibrick (if that's the word for it) that's attractive to me. I imagine they didn't have that size in 1913 though (does anyone know?) but it's still a nice classic look. If I find it on my other computer I'll post it! I've looked at Thassos which does seem too white. The in-person samples of calcutta are too grey from a distance (I don't want it to match my stainless counter so precisely) but yes I have time to keep looking. I also still pine for the Walker Zanger lightly crackled and glazed 2x6 tile I was all excited about when I thought I would do a honed black counter. haven't ruled that out completely, but it's $25/SF. Thanks!

Sorry I ran off there, things get crazy busy around here and it cuts into my computer time. Hopefully by bringing this up more people will see and comment. I think as a rule of thumb that honed is easier to care for. It would probably depend on how you use your fireplace though. Ours is a non-working fireplace that at some point we'll probably put a gas insert in. So the marble here will not get that dirty and should be able to be kept up pretty easily.
