Hi Kate, I don't want to come across as the Stone Police, but have you thought about using Porcelain look alikes instead of real limestone? There are a few threads about using limestone vs porcelain in a BR.

Again, I love the look of limestone, as I state in the linked thread, I DID have real limestone shelves in my previous BR, but I wouldn't and didn't put them on the floor in my new reno. I used a porcelain tile which I honestly think looks pretty real and is totally bullet-proof. You may want to look at the Supergres Everstone collection from Italy. Going from your choices above, you might like the Ever-Claire collection. What I really liked about it (I chose the Ever-dore) is that there were numerous variations of the tile, ie in 88 tiles, I had very very few repeats.

thanks rethinking the limestone

Ordered the Carrera marble tiles for powder and master. nervous but I had to choose something and I kept loving the carerra, so hoping for the best. It arrives tomorrow so I will see it and it goes in soon ( I have 10 days to return it if I don't like it)

we loved this one limestone but it is too pricey- we ordered sample limestones and stepped on them and they promptly broke. seems too soft and pourous so am looking for tiles for one more bathroom now. so ready for my hosue to be completed! so many choices.

This may be too late for you but porcelain tiles that look like marble might be an option to consider. My daughter just had Daltile's Florentine Carrera installed last week and it looks fabulous. No worries about staining, etching or sealing. It comes in several different sizes. She used the matte finish on both her floors and tub walls. She used 12x24 on the walls and 24x24 on the floors. Here's a couple of pics.
