If you guys have any other flooring ideas, let me known

You already have way too much going on. You need to throw some off of tge island. Use the black hex for the fllor, shower floor, and back wall accent wall. But only if you’re a glutton for punishment and daily cleaning. Black shows everything.

A shower that small does not need an "accent wall". Have all the walls the same. I agree with the above post that flooring in black tile will show soap scum and water minerals. You also better have really good lighting because the black will absorb the light. I like a bathroom where I can see my face really well in the mirror. Many restaurant bathrooms have black walls and floors and they are always so dim.

You're mixing very different styles and still need to select main floor... Start looking at inspiration photos that you like and break down the elements to get a better design for the space.

I googled “purple drywall” and learned it was mold resistant. If that is what you are putting behind your tile, prepare to replace the shower in a few years. Drywall of any kind is no longer allowed behind tile, according to the Tile Council of America (TCNA). You need a complete waterproofing system like Kerdi or other manufacturers make, or you need cement board (properly installed - look it up) and the proper depth of paint-on waterproofing compound, such as Redguard. Do some research. A contractor telling you “this is how we have always done it” is no substitute for TCNA guidelines.

Unless you want to replace tile, substrate, and studs due to the fact that tile and grout are not waterproof.

Oh my so much patterns you'll be dizzy walking in .My suggestion, take samples of these tiles, put them together so you can see how they don't go. Each on their own are nice but not together, think ranch dressing and ice cream, both are great but not together. I would chevron the floor using the tile in the picture of the shower - then go with a simple subway tile brick pattern on the shower wall. Keep it simple , it a small bathroom and you want to only do it once. Add wallpaper if you desire more pattern when you complete the reno. Good luck

Yes, I’m doing a reno on a shower and I used hardie backer concrete board 1/2 think for at least the floor and walls. More patterns in a restroom makes it smaller looking. Are you putting tile anywhere else in your bathroom? Or just in the shower?
