That's a cool space!

Pending your dimensions (can you post a layout?) I don't see why you couldn't do what you want if the toilet stack can be put in the right spot. (Is this a new build or a remodel?)

I think moving the shower fixtures to the other side (away from the door) would be preferable from a sightline perspective. Only thing is that you'd have to reach in and around to turn on the water, so it would be harder to get the water warmed up without getting a bit wet first. (We have a recirculator or whatever it's called up to our master shower, so that the hot water is almost instant. If you are opening up walls for new plumbing, see if you can do that.) We stayed at a vacation home once with an awesome 'party shower' that had the fixtures away from the door, but there was a second valve near the door so that you could turn on the water at that spot too. (No temp control there, just on/off.)

Also if you have space I think it would be nice to have a half wall between the toilet and the vanity too -- same height as the half wall for the shower.

Love the floating vanity. I'm a storage nut so I don't have one, but I think they look great.

There's no reason why the volume control has to be on the same wall as the showerhead. Put the controls where they are most convenient to turn on when you are entering the shower and where you can adjust them while you are in the shower.

That is a lovely bathroom.
However, I dont like that half wall. I dont like half walls :)

I would put a glass panel there. Put the toilet next and then the floating vanity with a single sink.
Also put two sets of shower controls/heads.

Finally, for 100% gorgeousness, do a curbless shower and carry the bathroom tile into the shower.

Then YOUR bathroom would be the inspiration for others :)
