What about a simple glass tile? Either a subway or mosaic could be beautiful with your granite; maybe something like this?

I was searching for something else and ran across this picture...thought it was pretty, too.

I'd go with a larger tile (less grout, less busy), plain color - beige, tan, brown (pick up color in granite).

I really like that deco tile you have in your picture with it. Are there any sealers out there that could give it more of a shine? If you really want to show off the granite rather than compete with it, it's probably best to use one of the same tiles you have already in the same room. I do think a glass mosaic blend would look great, but think that it would become the focus rather than the granite.

OK, I went to the tile store today and took lots of photos. Light/flash/glass don't always capture true colors or look, but it's the best I can pull off for now. I'd appreciate any and all input.

Multicolor mosaic #1

Multicolor mosaic #2

Multicolor mosaic #3

Multicolor/multisize

Solid mosaic #1

Solid mosaic #2

Chocolate brick

Tricolor rectangles (colors match specks in granite pretty well)

Solid, different sizes/shapes available

Unlike most of these samples, I'd use a grout that was pretty close to the tile color so it wasn't a big contrast.

I like the solid brown glass rectangle and the tricolor, but really there are so many nice ones! What a tough choice. Will they let you take home samples and try them in your bathroom?

I am liking Solid mosaic #1 and Tricolor rectangles in that order.

I vote for the burnt umber one in the last picture. Or possibly the chocolate brick. Some of the others (greens) look a bit 'nauseous' and I think they may be harder to work with when picking paint, accessories, etc. You are on the right track!

No. 2! Picks up all the colors.

Can we see a photo with the rest of the bathroom? I'm not sure about small glass mosaic tiles in all design situations... some just don't work IMHO. I would like to see everything so can consider the entire aesthetic...

Color-wise, love both the solid mosaic #1 and tricolor rectangles. Or if you want a larger format, perhaps the color of #1 in that (if they make it).

Dug this photo out of my archives to show more context of the room.

will the tile be going just where the granite bs was or will it continue over onto the tub and above?

I have that tub faucet in the kitchen version. It reminds me of a pepper mill! :)

Hmmm, I'm thinking glass mosaic might not be the right thing, now that the rest of the room is shown. I don't think it relates to what is going on around your tub. What about the trim tile that is around the tub, would that work? If not, of the choices shown, I think I'd do the larger format plain dark brown..it will mimic the cabinet color.

Another thought I had was if your type of granite is one that is available in tiles, they are usually much thinner than the slabs. Perhaps you could find some that "go" well with your slab and use those. They would look different anyway, just as your slab backsplash did, because they are on a different plane.

Have you considered travertine? You could have the majority of the backsplash in travertine and use glass mosaic tiles for some kind of an accent and sparkle. I found this picture which has one type of travertine matched up to a granite and cabinetry that are similar to yours.

I like number 2 as well.

I don't think I would introduce a whole new material. I would use one of the tiles you've already used, at least as field tie. Maybe you could add something different as an accent or listello/border tile.

I like what's going on in there already, and it's cohesive- adding something totally different as a backsplash just wouldn't make sense to me, design-wise.

I am very new to all this so take my 2c for what they are worth. I would not do glass tile backsplash. I like the accent tile over by the tub area-Is it a matte finsih too? can you add a sealer/enhancer to make it shiny-so it doesn't look odd next to the granite.

Uh oh, the votes are going against glass. :-( Is glass not Mr. Right because it's cool and the wood is warm? I think I agree that the mosaic (even if same color) wouldn't be the right choice. Too small for the scale of the room?

The accent tile on the tub wall also runs through the shower about 5' up from the floor. Would a third band over the sink make the room a bit too matchy-matchy? Plus it's matte stone, which, like travertine, doesn't go with polished granite in my mind.

I'm not sure if I could get thinner tiles in the granite (Autumn Leaf), and if so, whether they'd match or look different. It's a pretty consistent pattern, so it might not be too bad. I'll see what I can find out in that regard. Maybe our fabricator can make tiles out of our removed backsplash?

I agree that adding glass would be introducing too many materials into the room. It looked great before but if it's not practical then, so what. Maybe the fabricator can cut it width wise. That sounds like a good idea!

I have another idea that I am not sold on but I would like throw it out there, even though you already said you don't like the travertine by granite. I think they look just fine :/

You could carry the diamond patterned part from the tub over. If that seems too busy.. What about just a apx. one foot section in the middle as an accent and the rest is the solid tile.
