Hi All , about to start tiling the walls in my shower on jackoboard and tanked joints, I have two shower niches on the same wall to put tile trim around, my tiles are 9mm thickness so I was planning on using 10mm either straight edge or round edge alloy tile trim, could you guys confirm if 10mm trim is usually used on 9mm tiles or larger trim needed, and what style tile trim do most of you guys use , thanks
