any suggestions would be really welcomed....would it look best to have all 3 bathrooms similar or different?

thanks kats, yes we are building our first home. The main bath will be for the 2 younger girls (8 & 10yrs) as it has the bathtub, and the powder room will be for the older 2 (11 & 13yrs), as it has the bigger shower.

I'm assuming when our family/friends visit they most likely use the powder room toilet.

I'd LOVE beadboard, but it's not within the builders tender, so I have to stick with tiles.

I like the idea of using the same elements for cohesion, but I would not use the same tiles in the same way in each bathroom.

Maybe the marble look tile in your master bathroom. Do hexagonal accents under the mirror and bordering the tub with the subway tile.

In the main bath, use the subway tile in a herringbone pattern on the floor. Maybe do a medium grey tile on the walls with white in the tub shower area with a grey mosaic accent.

For the powder room, do a hexagonal floor with the marble on the walls.

Really, any combination could look good and you might want to post this in the home decorating forum for more ideas. They are very helpful.

thank you so much Karenseb, all your ideas sound gorgeous!! The only thing I'm thinking is that the tile shop might charge a whole lot extra for laying the smaller tiles, but I have my fingers crossed... luv your ideas thank you!!

Maybe add a little colour to the main bath for the younger girls by making the wall colour a light blue, which goes very well with the white and gray and carrara look. I would use a carrara marble look accent tile in their bathroom, too if I painted it blue, rather than just gray as Karen suggested. Gray and white is not so much fun for little girls.

I am doing similar colors to yours in my bathroom. I picked up several sheets of something called Tempesta Neve Tumbled Amalfi from the chain store The Tile Shop. They are little 2x4" tiles on a 12 x 12 sheet. What got my attention were the sparkles in the stone. It looks like someone spilled sugar in the rock. I am going to use it to top off the part of the bathroom walls that are tiled with carrara-look ceramic or porcelain tiles. I have white marble pencil molding (which cost three times as much as the Tempesta Neve Tumbled Amalfi did!) to go below and above the sparkly tile, then I will have the wall paint in a light blue. My bathroom vanity will be an antique lady's vanity with a vessel sink on top and I need to repaint it. I am considering Peace and Happiness for the vanity. The floor may be a darker gray porcelain or a medium gray octogonal tile. The shower is going to be gray and white swirl solid surface.

thanks nancy I love the colours you've chosen, so soft & pretty! I'm loving the idea of the Tempesta Neve tiles ... sounds like little shiny gems :)
