For a small bathroom, it's nice to use a smaller-scale tile. I'd recommend you look at mosaics. Maybe a 3" carrara marble hex? https://www.thebuilderdepot.com/cpiethh3x3hex.html?gclid=Cj0KCQjwm9D0BRCMARIsAIfvfIYt4FnwiCs0nIqZudR89TrGbterOE0y4-nmTm27gfMumPamgG_eokoaApO5EALw_wcB

I disagree I like large format tiles in small bathrooms they actually make the space feel larger , not so many grout lines to take your eye to. I aslo like to use that same tile for the shower walls, the fewer choices for a small bathroom the better it helps make the space feel larger. Same color but in a smaller tile for the shower floor . Then add a nice counter is agreat stone that works with the tile. A nice clean look . I really love marble look porcelain tile if you want a bit of pizzazz or real marble if you don’t mind a bit more work.

Actually, I want the bathroom to look larger.
I forgot to mentioned that.
Thank you!
