We recently remodeled a small bathroom and planned to have a backsplash of 4 X 4 brushed stainless steel tiles. Once my husband found the manufacturer and that we could buy direct from them at a fraction of the price than most retail sources, it turned into doing the bottom 5 feet of all the walls with them.
We like it so much we are planning on using them for some sections of our kitchen too. Very low maintenance, coordinates with many colors, and it would complement the other materials you are interested in using.
Here’s a link to the tile website. They were very helpful with technical assistance when we ran into a glitch with the adhesive.
(I don’t mean to sound like a commercial for stainless steel tiles nor do I work for that company but we’re enjoying peeing in diner-like ambience.)
