You can always go with textured glass or slump glass,it has a more rustic look and doesn't look so modern as plain glass, it's much easier to keep clean too as it doesn't streak and there is no grout...we have a very traditional kitchen and it looks amazing,this is my laundry and is actually quite a vibrant purple with dragonflies on it because,in the laundry,why not? The kitchen is more nuetral......

We have installed wallpaper behind glass splash backs on many occasions without any problems, the glass usually being attached by a thin beading of clear silicon applied around the inside perimeter of he glass, then fitted the day after the wallpaper install. MOST importantly the INSIDE of the glass be kept perfectly clean on install as even fingerprints will stand out

I would get in there to enliven up the space without taking away from the clean lines. You don't do that by repeating more of the same. You make the rest of the kitchen, with all its weight and clean lines play into something not the same. I would suggest you look at a gold leaf look ( ie with a little texture in it. Obviously not actual gold leaf) and put the most vibrant magenta pink/red that you dare in a horizontal line about 2 inches wide and going the full length of the area. Just very well executed paint. Make it above your average pot size so it does not disappear behind pots and pans. That way every time you will look at that place in your home and think Oh Yeah! Also, if you would rather .... make the coloured line turquoise.

Hearty Home. If it ain't broke don't fix it is your best slution. The pressed metal looked the part to moi; subtle character, and not like everyone elses. I've just renovated; all new kitchen has bevelled-edged white subways w' pale grey expoxy grout. Timeless is always timeless. Changing your pressed metal look could make the rest of the kitchen design look odd. I note this article is months old; So now I'm wondering what you did?
