I'm not a tile expert, just a homeowner. We used to have terrible water spotting, but have a water softener now so it's not as bad. My first and only thought about a shower re-do would be:: What can I install that I will not have to wipe off every shower? What is going to be the easiest, most cleanable surface? Therefore, I dream of having a solid surface shower stall, probably in white. But you need to decide for YOU what you are willing to deal with. I hope you bought a box of the tile and put it in your shower so you can live with it for a couple weeks and see how it looks. If not, I wouldn't rush into a shower remodel until you do that.

Putting in heated floors was the best decision we made for our bathroom. We live outside of Boston so it’s chilly or cold here 6-9 months of the year. Highly recommend.

Thank you, kind bumper :-)

I think of star and cross patterns as more Moroccan in style. Terrazzo is very fun. Are there color flecks in the terrazzo or is it white on white? If the former, find a tile color that picks up some of the terrazzo flecks and use that for the tub accent tile. I'd go with a 1 x 6 stacked mosaic. Obviously, the photo below is not a hot tub, but you can see what the stacked 1 x 6's look like: Gives it a little modern Asian flair, which I think works great with MCM homes.
