Tiling / backsplash question
When installing a granite countertop adjacent to a tiled kitchen wall, is it better to use a 4" backsplash? Functionally, it's probably unnecessary, so I guess the choice is purely from an appearance standpoint (would it look unfinished without the backsplash)? Is 4" pretty much standard for backsplashes, or do they come in several different heights?
Also, if the tile is in place before installing the granite countertop, is the countertop/backsplash just butted up against the tile and grouted? If neither the granite or tile has been installed, I assume it would be best to install the countertop first, then tile above the backsplash with no overlap. But I could be wrong.
A bit of background - the kitchen I'll be refurbing is a rental unit and I want to leave the existing linoleum counter in place for now, but will install granite in a couple of years, when I'll personally use the house. In the meantime, I want to tile the wall area above the backsplash. I'm wondering how the backsplash for a future granite countertop would fit with the tile installation.
I suppose the granite can be cut to the same height as the gap after the old counter is removed. Another issue would be the thickness of the tile plus backer board, which would likely make the backsplash close to being flush with the tile above it. This would look rather strange. I could leave out the backer board and install the tile directly onto the sheetrock, which would help a bit.
Thanks in advance for any advice!
