Hi wonderful people of Houzz. We're redoing out master bathroom & need help deciding on shower niche tile. The niche will be the length of the shower & the shower runs the majority of the back wall of the bathroom. The shower surround will be the calacatta, & bathroom floor the slab( the vanity is navy). My questions are as follows:

Which of the tile below do you think would go best?

Do you think the suggested tiles are too plain for such a large area & if so what would you suggest?

Would you trim the niche in tile matching the back such as the picture below or use a Schluter edge?

The shower surround tile does not have a bullnose tile

Thank you, you guys are amazing I love reading your comments & seeing your visions
