A first timer whole home remodeler and learning about different trims for shower tile. I’ve decided I’d like to trim my master shower with the same solid surface I’m going to use for master vanity counter. Question is … I have a pony wall. My initial thought was to trim all horizontal surfaces (shower curb, top of pony wall, bottom of shampoo niche, maybe shower window sill). Now wondering if I should trim vertical part of pony wall. Am I right in just horizontal or should I also trim “face” of pony wall vertical by door entry to shower? See highlighted pic below for area in question. A picture says a thousand words. Hah! Thanks in advance!
