Bathroom reno advice--vanity backsplash?
We are in the process of renovating all of our bathrooms, and I'm stuck on what to do about the vanity backsplash, particularly for the primary bathroom. We re-tiled all the floors and showers and our next step is to replace the counters with quartzite. We are also putting wallpaper in the primary bathroom. Functionally, a backsplash seems like a must, but I'm also seeing a lot of hate for ~4 inch backsplashes as compared to whole wall backsplashes. I don't want to put something in that is dated, but also don't plan on putting stone or tile up to the ceiling. We've been making all design selections ourselves and this tiny detail is something I can't sort out.
Any advice on what we should do and not do? Do we keep a ~4 inch backsplash, or should we do something else? If the ~4 inch backsplash is fine, are there simply certain ways to cut the stone that should be avoided (e.g., avoid the thick, boxy backsplashes)? For reference, the rest of our house fits into a transitional/traditional design.
Thanks!
