Nice job. I like it too. may I offer a few suggestions?

please get the gray outlets/plate covers for your wall.

that almond color isn't cutting it!

Or, even the black ones would work. they come in both colors at HD or Lowes.

If possible, paint your baseboard and door trim a brighter white so that it works w/your vanity white and toilet white. the creamy tone looks dingy next to all of the bright white shades.

Backsplash. how far did you want to use the tile? just behind the vanity up to the mirror? any chance of moving the outlets since they're right in the way?

you could try a mosaic tile in the same gray colors as the flooring

or maybe a wave pattern in a dark color?

wood/lave bar tile? (Tilebar)

penny tiles?

if you really want to jazz it up, tile the wall up to the ceiling

and over the toilet. (what kind of shower tile is there?

or, instead of a tile, you could do a MDF T&G molding on the entire wall:

as a suggestion, consider doing simple wood shelf like this at the bottom of the mirror and over to the left. it will help cancel the outlet cover and give you some extra storage

Thank you for the suggestions. the trim color is the same throughout the house. I could go with a bright white, like the sink with colored (black) outlet colors. One of my dilemmas is where to start and stop the backsplash. I was thinking about under the mirror, outlet to outlet. This is an Airbnb house and I like to attack a certain kind of clientele, but an entire wall is not what I was thinking. I purchased a black metal/oak colored shelf (great minds think alike), but I did not like the look. I will post a picture tomorrow. Maybe the location is wrong. Thank you for the post.

I was thinking about a tilebar backsplash, but I do like penny tile too

it's perfectly fine to paint the trim in the bathroom. it doesn't have to match the trim in the outside rooms. It's just that next to the bright white, it really shows too creamy. not a big deal to throw a coat of glossy white paint over it.

you could pick a backsplash and just do behind the countertop, side to side, and up to the mirror. you'd have to cut it to fit around the outlets.

I wouldn't use a larger tile because 1. the space youre tiling is too small, and 2. the larger tile (like a subway tile) really wouldn't match the more modern look you have going. Stick w/some type of mosaic or smaller tile. (4" would be the largest)

and to be perfectly honest, you don't HAVE to even do a backsplash. if you have a decent paint, it should be fine. Or, get a 4" piece of white quartz and run that along the back.

other than that, It looks great.
