Hi, does anyone have any experience with thin porcelain as a backsplash? I'm looking at the ones that look like marble. Currently I'm getting the same slab marble-look quartz backsplash as my countertop. What if I do a plain counter and the slab porcelain as a backsplash, will there be any benefits besides the size? I heard it's also stronger. Also is it generally cheaper or more expensive then the quartz? What other cost friendly options do I have to achieve the slab look? I want to minimize groutlines as much as possible!

I also heard it can be applied directly over my existing backsplash tile. Is this true? Thanks!
