Stoneshop The mosaic tile looks like a light blue, and the floor tile is a dark brown? Please correct me if I am wrong.

If so, I wouldn't want to introduce a new color. Here are two options for you--a neutral option and one with color. The first one uses tumbled Crema Marfil marble tile. The second uses porcelain tile with a river rock floor.

calikym The floor is charcoal, nearly black.

Stoneshop In that case, Carrara marble (or a porcelain tile that looks like marble) would look great in your space!

Susan Jablon Mosaics Something like this will look so good with black visit this website for more tiles www.susanjablon.com

calikym @susan - don't you have a glow in the dark mosaic tile that would match? Not sure the green really matches anything...

Calacatta Marble & Mosaic How about a 2" Hexagon Carrara?

calikym @Calcutta - do you have a large, honed marble floor tile (18" x36")? I am interested in this for my master bathroom. Need it ASAP. Plumbing is roughed in and already received resin tub. Thank you.

Calacatta Marble & Mosaic @calikym - we have 12"x24" Carrara Honed or 36"x36" Carrara Polished in large format tiles

Susan Jablon Mosaics @calikym Yes, we have glow in the dark mosaic tile on our website and you can design what you want from the designer link on our website www.susanjablon.com

DIRECTBUY OF FORT WORTH Emser tile has some great options for you on this. There is paladino a porcelain that looks like marble without the worries of marble. Then they have a prhttp://emser.com/index.php?name=PALADINO(TM)&id0=ceramic_porcelain&id1=collectionDetailsIntro&index=52&scrollMenuporcelain=293oduct called Direction that is an unglazed through body porcelain with a very neutral color palet.

calikym @directbuy - thanks for the lead! I have about 6 different boards at my house for 2 different bathrooms. Emser tile opened up a new world of possibilities. In my master, I'm looking for arctic white tile, larger format, and then lots of glass. It's very tough to find families of tiles that coordinate and whites are soooo...hard to match. Thanks again!

MarbleWarehouse.com My choice will be 24"x24" or 12"x24" Brazilian cleft or honed slate

ginitbirs Try stone on floor. Feels great on feet.
