I have a similar question five years later: Is the 4" matching back splash now out of style? And how long will it stay out of style? Doubt that it would be possible to get a full matching back splash 14 years after the home was built. I am considering removing the 4" back splash and going with a complementary tile or, perhaps, a colorful wallpaper. Thoughts as to how long the short back spash will stay out of style? (I'm old enough to remember bell bottoms - the first time they were in style.)

Have you thought about stainless steel backsplash tiles? https://www.houzz.com/products/4x11-honeycomb-matted-metal-peel-and-stick-backsplash-tile-set-of-3-brushed-st-prvw-vr~100903589. These tiles would look great with your stainless steel appliances.

Carrara Marble is a great choice! It is neutral, you can use any color! Take a look at our website to see some options for backsplash! I highly recommend ordering a sample of a tile before you make your final purchase. At RocksinStock.com, it is simple to request a sample. Create your account and start browsing. Seeing the tile in real life will give you a new perspective.

I don't know what your client has in mind completely. It might be worth asking the client for some inspiration pictures for what she has in mind.

Super white glass tile Maybe something like this with a tiny bit of pattern: Silver planks glass tile Or maybe this one which might work with the colour in the counter: glass mosaic - raw silk
