I'm all for bold choices (had a black kitchen sink once - water spots a pain, but I liked it, had a black-walled office once - huge window and high ceilings so was fine)
buuuuut if this is for your ABB space, I'd say maybe not. 1. Guests aren't always too creative 2. it may get dinged for dirty even if it isn't
And the shower pan is the last thing anyone would ever want to change. Shower glass, fine. Wall paint, easy. Tile, doable. Toilet, switch in a day. Vessel sink, easy. Whole vanity, ok. Lighting, easy. But the shower pan only changes for an entire gut job, nothing survives that swap.
