Yes - we have white marble (calacatta) in our master bathroom. Would I do it again - YES. Is it easy to keep clean - YES & NO. Marble is a VERY high maintenance stone. Soooo many things can stain or etch it....even water spots can leave a permanent mark. If you want something that always looks like the day you bought it...don't buy marble. If you can live with a surface that eventually will patina with a worn look (etches, scratches, marks, etc.) it may be for you. I have been kinda paranoid & religious about maintaining and cleaning the counter (had it for 3 months now). I won't apply makeup or hair products in the bathroom (use bedroom vanity) and I lay a towel down on the counter when brushing my teeth or washing my face and then wipe it up immediately every night with a marble cleaner. Again, we love the marble so it is a sacrifice we are willing to make and we understand it won't be perfect forever. So far no marks, but it is kinda like a new car. I know the first few marks will happen and it will be traumatic but you eventually get over it. As for our upcoming guest/hall bathroom remodel.....we we will have marble on the shower walls but a quartz countertop. I just don't want to have to worry about it in another bathroom so we are planning on no marble on any horizontal surfaces (floor or counters).

I love the marble top I received and it was very similar to the one I saw in a RH store. You can also purchase samples of the counter material online ($20 I think?). I will probably be purchasing some samples now (yes, after the vanity is installed) to test out soaps and find out what will or will not etch. I think a dark gray tile on the floor and white tile on the tub surround would be absolutely lovely. Personally I would use tile colors in the "cool" family (whites, grays, etc) to be in keeping with the cool colors of the carrara top. I will definitely post pictures when I am finished. Things have been a little crazy lately and I'm at about the 90% completed mark and am struggling to find time to finish.

make-up, nail polish NP's removing, but scratches you betcha....mostly of the clear shiney surface, and can buff out with Gel-gloss..

if you went w/gray, match the lightest shade of gray in the flooring you choose. it would be easier if you listed the choices of the laminate you're considering. but really, any of those you pick will work. off white, gray, charcoal, white, black,,,,all will work. gray tones are many. some are cool, some are warm. that's why I said to choose something that goes w/the flooring. you want a neutral gray, not overly blue/cool or overly warm/brown toned.
