When tiling, do your calculations from the center of your space to be tiled. The cuts should be equal on both sides. If one or both sides have exposed edges, you can purchase tile with a finished bullnose edge.

Do not lay out starting with a full tile. You have a deep beveled edge. If you start with the bevel the offset cut under and above will not have the bevel. This looks really bad. If that is a 3x6 tile you only have approx. 2-1/2" to shift. You want all cuts against the end panel and window trim. Use the flat portion of the tile for layout purposes. You don't want the bevel or a portion of it against anything. Ah yes the things they don't show you on TV:)

move them over to the right. It will also give you a bigger piece on the left side that you have to cut. normally you start in the center so both ends have the same cuts, but in this case, you don't want small slivers next to the window. How will it work out on the other side of the window?

also, consider doing away w/the glass accent tile.

Center if possible. It is more important to avoid your cuts in the bevel. There will not be any bullnose for the stone you selected. If you need you can use a profile edge but you must cut all the tiles for a consistent edge. Even then it's not a good look. Do you have a open end that requires a finish detail? If so I'll provide a option.

david, would you mind posting a pic of the entire counter w/the sink and window? and maybe another pic showing the entire kitchen w/the cabs and flooring?

this might be better. Is your counter Rainforest Brown?

Don't use ANY of that tile. It completely clashes with the granite.

I agree with some of the other comments that the backsplash should be dead plain, so the granite is the star. If doable, I suggest replacing all of the tiles on the backsplash with a dead plain off-white tile and using the metal scroll border as a transition between it and granite top, something like the samples I've attached. A second idea is the "pebble" and chip tiles for the backsplash. Even though this tile may sound too busy for the granite, I don't think so. In fact, I think it blends beautifully and enhances the granite countertop while making it unique and very interesting. Good luck, David.

Sounds like a great decision, David. You will be so much happier with the results.

Why is the glass tile detail not at a consistent height? It's 4 tiles high on one wall and 5 tiles high on the other.

I would use a lighter simpler tile. It appears that you are not an experienced tile person and you are picking a tile that is not that easy to use because of the bevels. At the least delete the glass border it will date your job if it isn't already dated. Glass mosaics are played out.

When you grout beveled tile it also takes a smile hand as the bevels pack with grout and you have to be able to leave a uniform amount in the gap vs filling the bevel.

let those wood cabinets be the star and tone down the backsplash.

I know it's not on trend, but I would go even more simple than these recommendations and do a back-painted glass. I prefer that backsplash in kitchens where there isn't a lot of space to appreciate tile detail or with very unique countertops.

Golden/bronze penny tiles would be amazing!!

HIwE, good point. David, the bronze or copper tiles could also work. I would hope you have under cabinet lighting to begin with. these would really shine and enhance your countertop.

copper lantern/arabesque tiles

golden bronze mesh tiles

or a larger format bronze metallic tile

Penny tiles are so easy to install too! Come on mesh sheets easy to cut.

That's a great color w/those cabs tetheridge. David, back-painted glass is another option. It's usually seen in more contemporary type kitchens, but it will work in one like yours. It's not a DIY thing since the glass needs to be cut exactly to fit your cabinets. They also paint the backs w/a special glass paint (otherwise it won't adhere properly). These are all great options for you. let us know what you decide.
