I put the tiles I was thinking about using in my shower and gave them a little test run to see how they stand up to water spots and whatever I threw at it over time. I was gutting the shower any way so what the heck. Now, I squeegee my entire shower and then wipe with bath towel before I get out. I went with glass tiles so I don't want to deal with the build up. I love the contemporary look as well. I like your tiles that you have chosen. Just remember that the darker shades will make the room look smaller overall and you will probably need to up your lighting as the darker room will suck up the light rather then reflect it. I would add some stainless steel edge trim to really bump up the contemporary factor. You can see examples at Porcelanosa usa. They have wonderful products, in fact your tile looks like it came from there. Let me ask you are you using PLYBOO for your cabinet? I am very close to pulling the trigger on that decision this week. Here is a link that might be useful: Porcelanosa

It's hard to tell because I'm looking at a photo but it appears your tile has a yellow or green undertone to it (like I said, it's hard for me to tell from a photo as everyone's monitor reads color differently) whereas Wind's Breath has more of a red undertone that will fight it. If I'm correct and the undertone is green in the tile, the Nature's Essentials will be a better match. Best to buy a pint of both and paint them on the wall next to the tile to see before committing.

I like the wallpaper and the black/white floor tiles. It has a lot of pattern but I think it's fine for a guest bath. I would tile the shower area with green instead of blue, to match your vanity. Emerald green with black and white can look great. The paint your mirror frame black or green.

I am refreshing my master bath to some degree - replacing shower floor pan (from old white pan to some type of tile), replacing shower faucets (to a new rainfall shower system), replacing vanity to a more up to date white vanity, and want to add some tile to extend my shower tile to the ceiling. I am keeping the light beige marble (see photo) which is where I need some advise; the marble is on the floor, in the shower, and around the tub area What type of tile will compliment this marble and bring in a more up-to-date look? I really would like to bring in some white tones into the bathroom with the new tile and want to keep on the neutral side. I'm struggling on selecting what type of pattern (e.g., plain wave, mosaic, subway?) to bring in to my existing marble bathroom. I am thinking of putting the new tile on the shower wall above the old tile to extend tile to the ceiling, possibly a border on the sides of the current shower, and a border around the tub tile with the new tile. Any advise on a recommended pattern? Also should I try to keep the shower floor tile the same as the new wall tile? Any input appreciated.
