I like #3

Recommend against large floor tiles. Smaller are better for the slippery factor.

I like 5. most cohesive

None of the above. Too many disconnected similar scale tile choices thrown together.

c3pw and design 6 are the best of all the evils. They are all incredibly too busy.

Sorry, I don't like any, but the 3rd and last are the most pleasing out of all to me.

3 but without the horizontal band as well. and different tile. high contrast mosaic is looking old.

I'm afraid most would trigger my seizure disorder lol but I would choose #5 out of all of them.

Always remember "Less is More".

If these are the only options, I would choose the wall tile from #4 and run it on the walls and floor and bench. I would then use the band tiles to encircle the space at the point where the bench meets the wall.
