I think you should create the L shape and let it flow. Have you considered making the backsplash a brighter color?

I suggest you take the backsplash tile to the underside of the top cabinets and then take it straight across to the window. Due to the shape of your range hood, it will be next to impossible to take the backsplash up to it. Alternatively, make the backsplash as high as the bottom of the top window. These ideas minimize "competing lines" in your kitchen.

Please take a look at my pictures and let me know if there is a few that you like and maybe we can come up with some ideas to make your kitchen look just the way you always dreamed. Thank you

I agree with CB Kitchen Designs, get an electrician to move that outlet so it isn't visible.
I'd put the backsplash from counter to cabinets, and then range hood to counter. The type of backsplash will determine whether you carry the backsplash treatment to the door at the range height or drop it down on the left side of the range. This is an easy question for your tile setter once you have a tile selected. If DIY, pick the tile first, and then play around with it on-site to see what you like. The difference between higher or lower is maximim two squares, an insignificant amount of waste if you decide to lower the backsplash on the left. And if DIY, you'll waste that much elsewhere installing the backsplash.
Here's another tip for DIY. Always carry the backsplash behind the range to counter height. When you replace your range (life expectancy is now 7 years) you'll be glad the backsplash goes down low enough for a countertop range if you change to that. Otherwise you may have to rip out the entire backsplash to fit to a new range. Needless expense if you just run it a bit long now.

CB Kitchen Designs nailed it. Once you follow their recommendations, I'd also suggest running the tile to the ceiling, wrapping it around the hood. A good tilesetter will have no problem doing that. That space is begging for glass subway tiles set upright narrow ends facing up and down, not horizontal to match the beadboard cabinet doors.

I agree that your first priority is to address the electrical outlet above the hood. I would add that part of the issue here is that the hood doesnt feel centered on the cabinetry. Ideally, you would have the same amount of wall space to the left and right of the hood. The hood feels too tight up against the cabinetry. This may be difficult to fix, unless you can replace the last wall cabinet with a narrower one. Regardless, i would agree with Atlantic stone that you should use a small mosaic or strip tile and run it along backspash, behind the hood, and all the way up the wall to pull everything together. More tile will cost more, but you can probably find something nice even at home depot. i am attaching an image of a mosaic that came from there that really pulled all the colors of this kitchen together. good luck!

Yes definitely fix the hood receptacle. I'm a fan of subway tiles glass or ceramic - standard horizontal brick pattern. choose a color to compliment or keep it monochromatic - depends how you feel on that.

Thanks everyone for all of your comments. To answer the outlet question above the range, there is a stainless chimney that will cover it. We obviously left it off to do the tilling. We found some nice glass tile yesterday and we think we are going to set it longways to match the cabinets. As for the spot to the left of the range we are still unsure if we do one 1x1 tile there or do we carry it up the wall?

ah, glad you clarified about the hood ! My preference would be to carry it up. Cheers.

If you are going to enclose the range hood so it extends horizontially to create a visual boundary for the tile, that would be good. I would carry it up to the hood. It would look odd having a space of painted wall between the hood, and the backsplash behind the stove, if there is not wall space on either side of the hood, to carry the eye up to the wall above. If there IS, I would just keep it to the height of the space between counter and cabinets.

Yes, very astute comment about carrying it LOWER behind the stove. Use trim tiles to finish the design, and don't go around the hood up the wall. You will encounter the door, and narrow space above, and no logical place to end. "Orphaned" ends of tile designs, that end up in an awkward place, or " the middle of nowhere" grab the eye immediately, and detract from the design, and all the hard work and expense. Ending the tile at the door molding at the little space at the top of the door would not look good.

You can always tile the rest first, and the the same height behind the stove, live with it for a while, and decide if you want to go higher.

Pretty Kitchen! Good Luck!
