I have seen a lot of bathrooms in show homes lately that have carried the floor tile right up the walls of the shower. Both light and dark tiles are used.
Personally, I hate it. It doesn't make the room seem bigger because I can't tell where the floor ends and the wall starts. It feels like the wall is right there when it's actually several feet away.
I also find it boring. One colour, no change in texture or shade. And it's never even nice enough tile that you would want that much of it.
OntarioMom, if you like the options you've picked, then don't let anyone talk you out of it. If you personally find it a little busy, I would change the counter to a colour similar to one of the tiles. You've got a white vanity, and basically white wall tiles. Add in a white counter material, and the only difference is a dark grey floor. And paint colour could be absolutely anything, since you've only got grey and white going on so far. Same goes if you pick a darker grey counter top to match the floor. Or, as I said, keep it as you picked it. The medium grey counter is a nice in between colour. A quick houzz search brought this pic which shows the dark floor and counter, with light everything else.

Anyone who thinks this photo is busy needs to take a look at some 70s bathrooms.
