A 9’ shower , hope you are planning on a crowd to keep you warm, IMO that is just too big you will freeze your A-- off in there as for the tile I like the 1 st one

I like them both. The first one looks more luxurious and glitzy to me, and the second looks more spa-like, natural and relaxing. I'd most likely choose #2 if it were my bathroom but they are both beautiful.

I love the first but only for the walls. They're so shiny I'd be terrified of slipping.

I like the travertine one. It has less variation so the tiles themselves won't seem so obvious and the look is more seamless. The color also seems slightly warmer, but that may just be the photos - be sure to see them both in your space and lighting.

Some tiles are available in both a polished and a matte finish. Use matte on the floor.

Thank you everyone
