Hello, Since you are planning on keeping the vanity cabinets with dark granite countertops along with white subway tiles, I think an easy solution would be to bridge the gap between the countertop and the subway tile by using a white marble look floor tile with dark veins. Below are just a couple of tiles I found on Houzz. I think using light-colored floor tiles would keep the bathrooms from looking too small or dark compared to using darker floor tiles. Are you also planning on painting the walls? I think painting the walls in a gray color would be also a quick and inexpensive way of making sure the whole space looks good. The current paint color looks like it's on the yellow side and I think your tiles, granite countertop, and the brown vanities would definitely look better if the yellow walls went gray.

They look good together! I despise matching sets of things; it looks very builder-ish.

It’s going to look FAB! I think a ceiling height of 9ft and above can cope with colour & small bathrooms which add a little unexpected WOW are fun!

Thanks to both of you. I will definitely look at the mirror back light below and above , as I was planning the below one anyway. That makes sense. Outside of that, most of the beautiful pictures you shared were including recessed lights, which I cant really do because of the concrete ceiling. We thought about doing a drop ceiling to add can lights (ultra flats ones) but that would force us to redo the doors for the whole floor which are custom floor to ceiling height. That is why I was considering doing that same thing but just partially (just 6 ") from the vanity through the shower/tub so be able to have the recessed light look. I am just struggling getting a clean look, without those options. If I can't do that, and I cant do the sconces because there is just not much room to add a sconce between the sink and the wall next to the vanity (it is only 30" wide and our sink is a large rectangular vessel sink), what other options would you recommend?
