Yes for glossy in the shower, great!

white subway for the shower sides and the marble for the back wall ... kind of run the floor up the wall on the back wall of the shower? When you walk into the bathroom, are you looking straight at the shower wall?

a few things to think about. Have you looked for bathroom tile ideas?

small mosaic tile accents are too trendy, and don't always last the test of time.

Why not just you the same large format tile for everything, including the niche, and so called accent? Classier.

I am guessing you don't have the square footage to make the accents mean anything

... photo of the room would help.

Yes I think so - we did a matte charcoal floor in our recent bath reno with glossy white subway in the bath/shower - I like the contrast

We just built and I did matte tile floors in the bath- I feel like every water drip leaves a mark and I’m constantly cleaning! Any advice?

@la_la Girl, we are in the midst of a bathroom reno that sounds similar to yours. Would you post a photo of yours? I'm trying to figure out if we should add grey or black pencil tile (or wide) as a border and to break of the big white while. We also have slate colored tile already in bath, and likely putting in black matte fixtures. Thanks!
