Sounds like a lot of shapes- I would try to get things to relate more- for instance hex on floors only, 6x6 squares on all the walls (or whatever size matches the fabulous accent tile) but in the coordinating color. I would tend to have the wall and floors different... The off white doesn't seem to match the accent wall so maybe green walls terra cotta floor?

Green walls and terracotta floor is what I initially wanted but I’m having a hard time finding a terracotta I like. I wish this green tile came in a square. I totally agree it would be better. I can do the hex on the shower floor but was worried it would be slippery. It is a matte tile though.

I agree it’s cool as an accent but might be overwhelming

I’d faster go with something like this:

Or this is also a cool idea.
You either get some of each tile and mix or you can do all of one.

If it is matte it doesn't matter- my bathroom is all 8x8 square with no issues (linear drain)

Good to know. Then I would do it all hex. Alternately I could do 2x8.

My vote is to have the same tile throughout the entire shower - something calm and serene.
