Beenie, I love that flower pattern and have seen it used in some really nice bathrooms. For me personally though, when I've seen it used in a smaller bathroom, I think it tends to look a little busy. Same with the Onyx, it's beautiful, and would look lovely in certain applications, but I don't think it works with the other elements you've chosen, (but again, that's just me). In contrast, when I look at that pretty white embossed border along with that pretty white subway, it reminds me of Sweeby's bathroom. Understated and elegant. Which is why I think the darker marble would look pretty, as it also leans to the quieter side, and can offer some contrast. If you don't want a dark floor, I also think it would look really if it were cut into 3-4 inch strips used as a border with some sort of a white tile. I had never thought of dark flooring as an option before either. When bought the our house it was a fixer in need of some love, the bathroom was so aweful to be honest, I didn't even notice the floor and to be honest, I was going to pull it out of there! However, after we fixed some wall and color issues, the tile definately grew on me. We ended up grouting it, and will do something in a few months to help the finish.

Calcutta gold mosaic (3/8") was my first choice for our bathroom floor. When I saw it at the tile store, it was mounted and grouted and I swear there is no prettier stone in the world. They didn't call it calcutta but crema fantasy. When the salesperson ordered it she mistakenly ordered crema marfil - which IMO is not even in the same league as calcutta. It turned out that this particular manufacturer discont'd the calcutta and the only other place I could find it wanted over $30 /sqft. I just couldn't justify the cost. What does this have to do with you? Well, it's just my round about way of saying - Yes, yes, yes, go for the calcutta mosaic floor! I would just love to see it installed. Now having said that, keep in mind that it won't be as carefree as a ceramic floor. When I was staining our door and the mahogany stain seeped through the drop cloth and onto the new tile, I was pretty happy we had gone for the ceramic hexes. No matter what you go for, please post pix. It sounds like your bath will be wonderful.

I just realized I did not answer your question. No, the two are different. I am not good at posting pics so here is a link to kitchens with Carrera and also with Calacatta Gold. There is also a Calacatta Green which is what I was really hoping to find a small slab of.

Well the kitchen is almost done. The floor is my favourite thing! Absolutely love them! It is porcelain wood plank layed herringbone butting up against the hardwood floor. The hardwood and porcelain floors do not look the same but they do have the same tone. I think they look great together. It was hard to get a good pic because the lighting is different in the kitchen vs the hall.
