First pic is current. I'm thinking to replace the tub with a layout shown in the second picture with a tub on the left and a shower area on the right. The width is 7.25', I think it can work. But I have no idea how to proceed with tiles and/or tile combos. Matte vs polished? White, white/grey? I read I should do smaller tiles on the floor for better sloping? In general what I like is white tiles with grey marbling design (but not marble). So I would love suggestions on styles/colors please! 🙏🏼
