Go frameless. The aluminum frames around glass shower doors are a magnet for gunk. Going frameless on your glass gives you a simple sheet to squeegee clean. There are a number of options for coatings on glass that also help it to repel water and soap scum. Check with your glass shower door manufacturer for factory coating options. Many people recommend manually applied water repellants like Rain-X
Select a linear drain. See that narrow channel at the base of the wall? That's a linear drain. Installing one means that your shower floor will have a flat slope in one direction, so you can run your large-format floor tile right on into the shower instead of using little mosaic tiles to accommodate multiple directions of slope. It will set you back around $1,000, but ask yourself how much you hate cleaning grout.
Sloped floor in shower; no lip; drain far side from glass door.
