We are using Corian for a kids' bath remodel. We have it in our 2 other baths, and love it. Many colors to choose from (with speckles and variation to hide water spots), easy to clean (I use Bon Ami when regular cleaning stuff isn't enough), and not too hard a surface. We also find that having the integral sink makes cleaning very easy. You may find that it isn't the most popular choice as so many people like natural stone, but it works well for us.

For our new house master I'm using a fantastic honed marble look-alike porcelain tile, 16x16, and I'll tell you why. Last house we did an extensive master bath remodel with three different kinds of white marble. It was amazing and the complements were off the charts. I loved how it looked but I *hated* how it lived. I had water etching all over the place, even after sealing three times. Honed will help with that I think, but I believe even honed will etch. Honed also isn't as stain resistant, so you have to think about that, too. And it was indeed slick and we had to have rugs everywhere. Honed might help with that. But the tile we're using is an amazing replication of a honed marble, and I'm picky (won't even consider the marble-look solid surface counters because they're not realistic). Or you could find a granite look-alike tile. As I'm out there looking for granite for the kitchen I keep seeing all this gorgeous marble and lots of different opinions from granite suppliers and fabricators on using it in a kitchen, mostly negative. It tempts me every time. I absolutely love the stuff. And I'll never use it for a practical application again.

A pedestal tub and cherry cabinets can be either traditional or contemporary - which direction are you going? If you were going traditional, riffing off Bill's idea, what about one of the larger hexes, 2" (Daltile Keystone Shapes) or even 4" (can't remember who makes it but I know someone here in the last two years used it)? American Olean "Chloe" mosaic with the white or silver-gray centers would also be pretty. If money's very tight, the white-on-white version of Daltile Octagon-and-Dot, which is quite inexpensive, would provide plenty of visual texture and, with a silvery gray grout, enough pattern to keep it from being a dull white floor. However, I think the carrara counter might get lost against a white or white-and-gray floor. If you're leaning toward something more contemporary, I think a slate-look porcelain with a gray-blue base and brown accents in it, like American Olean "Earthscapes" in Rainforest, would look really smashing. Blue is a wonderful complement to cherry and the gray would tie back to the gray in the marble. Green tones are also wonderful with cherry - maybe Daltile "Continental Slate" in Brazilian Green (this has a matching mosaic for a shower floor) has enough gray to pick up the marble veining as well as green and brown to complement the cherry. Or something slicker would be a sort of concrete-ish look, like Daltile's "City View" in "Downtown Nite" which is sort of a medium gray. Daltile's "Donegal" in Grigio would be a subtle but not dull floor, in a silvery gray to pick up the marble veining; it would allow many other things to star and keep the feel of the room lighter. How much maintenance are you willing to deal with? A large-format charcoal gray (like Daltile "Era" in Olos) on the floors would make the cherry glow and both the carrara marble and the white tub "pop" as the "stars of the show", but a really dark color does show every trace of lint and hair and soap scum. I could see it as well for the shower - a colorbody porcelain tile could be cut down to the appropriate size by your tile setter, since you need smaller tiles for traction - with a decorative band or two of carrara tiles horizontally around the shower and as a border on the floor to get the maximum impact from a minimum amount of the more expensive stone. Since your room is so big, you could get away with a big tile - the "Era" tile comes in a 12x24 that could be laid in a common brick or a herringbone pattern which would look amazing. Daltile "Veranda" is a pretty reliable tile, in Gunmetal or Patina for the darker look, or Steel for the lighter look to blend with the countertop. It comes in a 6x20" which could be used to create some really great patterns. There are a lot of great tiles on the market, BTW, I'm just most familiar with Dal and AO's lines, they're very easy to find and for the most part reasonably priced. (If you're interested in something from Daltile, watch Home Depot for their 20% off all special order flooring sales, as this includes all tile. Their prices beat the living ahem out of any of the tile stores when I ordered my Daltile tile there. It's exactly the same tile as you would get in a tile store, don't let anyone tell you it's inferior.) Did you have any plans for the main bathroom's walls? Tiled wainscot, just paint, special finishes like Venetian plaster?

We put in marble in our main bath (old house - we all use the same bathroom). I love it so much, it is exactly the look I wanted - BUT, if you get marble, you have to know that it WILL etch and be okay with that look. Ours has been in for about a year and it is completely etched around the sink. We have no stains but lots of etching. We also know many people that chose it for their kitchens and have the same thing. Sealer will prevent stains, but etching is inevitable. What sort of things will cause etching? Everything. Toothpaste, mouthwash, shaving cream, etc. Don't think you can avoid it by being careful - you can't. Some here have suggested that you can buff it out with fine steel wool. I haven't had any luck with that but maybe just didn't keep at it long enough. Like I said above, I love the look and wouldn't change it for anything with or without the etching, but if you want it to stay pristine, you should look at something else. A friend just did her kitchen counters in a marble look alike called Caesarstone Misty Carrera. It's a darker gray than our carrara, but nice and pretty much indestructible. HOpe this helps.
