Found a great tile source: www.hakatai.com
You can create your own custom blend from the stock tile colors and view a generated image of the final blend. Pretty slick... and it won't break the bank. Here's the blend we will order for the bathroom!
I think we have scrapped the bathtub all together, and have opted to create a walk in shower. It's the second bath and the kids don't use a bathtub... besides the master has a tub if we need it. The tiled shower will work great. Now, we have to dispose of the tub. (sigh.)
