Edit to my earlier. That bench top should also be solid surface.

Truthfully? Not understanding the need for ONE shower wall in light blue. Too many ideas when good idea would suffice. Add a picture of a waterfall somewhere : ) What IS the white tile? What is shape and size? What is the counter top surface for vanity?

Sounds just a bit like you're trying to walk a line between a wee bit farm and a wee bit glam.....don't walk the line, pick a side: )
