split vanities with seating
I like the idea of doing furniture pieces for the vanities
Create a long countertop to extend the whole length of the wall and adding a seat could add a splash of color and be comfortable place for makeup.
having the left-side vanity be along the far left wall and extending the counter top into the shower for shampoo, etc.
If you go with a curbless shower, it may make sense to do a linear drain
keeping things simple- having only one pane of glass for partition between the shower and the rest of the bathroom
