I'm redoing backsplash and need advice on how far up to bring tile. I plan to have a stainless steel panel placed under the hood to the stove top. Because of the previous asymmetrical pattern (not done by me!) and damage to the wall after tile is removed, I need to at least have a tile border around the planned panel (that is not asymmetrical!). Do I keep the step up/down leading to the border or do I tile the whole wall up to the hood line? Thanks!!
