I think there are two issues to consider here. One "technical" and the other "decorative". The first is technical, it has to do with the size of the grout line and the type of grout used. Unsanded grout is for grout lines less than 1/8" wide. Sanded grout is for grout lines 1/8" to 1/2" wide. If the installer exceeded the manufacturer's technical limits of the grout, it's a technical bad on him. Somewhat muddling that issue is the fact the your husband approved of the installation "as is". From the decorative perspective, because your husband approved of this, you really have no recourse. A third perspective that I'll throw out for the heck of it is one of pride. This could have been resolved in a couple of ways during layout. Your installer has no pride.

Thanks for your input Ingrid. After Celebration's comments, I went out on Google and searched for "Old World" floor tiles. I found sites where you could purchase reclaimed tiles or new imported Italian/Spanish tiles. I noticed quickly their tiles are not the large 18+ inches tiles, but smaller, uniform tiles as you suggested or are random mixed sizes as Celebration suggested. I guess I need to rethink my direction and not get caught up in size recommendations that seem to be popular in this country.

You are right about the colors in the inspiration room rug pulling in all the colors of the room. Somehow I either overlooked it or didn't want to admit it. How does the saying go..."sometimes you don't see the forest because the trees are in the way"...haha... Anyway, I just fell in love with the stone medallion rug and was offered it for a great price because it was a return to a local place that makes them. It isn't the colors that I would have chosen, but I was trying to force it to work. It has no grout because it is made with a compouter controled water jet and all the pieces fit tightly together to form one big solid piece. It's really lovely, but you are right, the colors aren't the best for the design. I have changed original design a bit because I felt it was too Tuscan/Mediterranean for the house. I am using more rustic wood instead of so much cast concrete..though I am using the cast corbles that flank the radius ceiling. I wanted it to feel casual and rustic French, but with an elegant touch of "jewelry" that the crystal and possibly some glass tile accents would bring. The color swatch under the sink is such a bad representation of the vanity color! I attached a photo of a premade cabinet in a similar color and style to what I am having made. The wall color has not been determined yet. Any suggestions?! Thanks again! Your advice is really helping me see this from a different prespective. Did I mention I am a bit over my head with this project? This monster spec house has 10 bathrooms and not enough budget! I'll post some pictures as the project progresses.

Is this rental in a market where the renters can afford to be so choosy as to reject a house because the floors don't match? When I last sought out a place to rent, flooring aesthetic wasn't even on my list of concerns, as long as it wasn't carpet (and that was a functional concern). It was stuff like "are there enough bedrooms" and "is the locaction good" and "is there a dishwasher". The wood floor and wood-look vinyl do not look good together, sure, but is it worth tearing up and replacing right now? If that level of detail is indeed crucial in your market, I agree with the slate-look sheet vinyl. In my old apartment, it was all original hardwood (1915 building) except the kitchen and bathrooms, which had sheet vinyl that looked vaguely like travertine. Wasn't the best looking, but was functional and super easy to maintain. Sheet vinyl is great for rentals, and they make some good looking patterns now (like the slate). For whatever reason, I've always been fine with tile/stone-look vinyl and vinyl-look vinyl, but I just don't like the wood-look stuff.
