Argh - I did not listen to myself - always bad idea. Small bathroom, half wall to separate toilet from shower. Shower to be tiled in white 3x6 subway. Half wall 45 inches tall, not counting short caesarstone that will top it. Thought to continue tile around wall and carry through room, using as backsplash as well. Concern that 1/2 wall is too high to continue wainscoting look through room; would prefer it was 42 inches, especially so there would not be 9 inches of backsplash.
Posting pic, don't know if helpful, as room down to studs( except for shower, which has truly been "set in cement"). BTW, I am assuming taking 3-4 inches off wall now would be major job? Thanks in advance- I'm sure I will be posting more.
