There are many examples on houzz of contrasting counters for perimeter and island. For example butcher block on island and stone on perimeter or a solid color on one and something with movement on another. I would only mix two stones if one had movement and one was fairly solid. The stainless on perimeter and something else on island sounds good to me. Here is a pic of stainless counters with what looks like a stone breakfast bar. (I hope I understood your question right). http://houzz.com/photos/3137660

Absolutely no problem changing up the carpet. Things to watch for......make the transition in a doorway, an opening or along a visual break in the rooms (like the corners of the walls). I would stay in the same colour range, but just go to the other end of the spectrum rather than change the colour completely.....like light grey going to dark grey, not light grey going to navy blue. You want the separation but an easy transition on the eyes.

Love blue tiles. Depending on how much sun and how hot your pool gets in the summer should dictate what color it is. We live in Arizona, so cool blues work best. Our neighbor has brown tile and a dark pebble tech pool. Looks like a swimming hole and gets really hot - 94% water in the summer. They obviously didn't think it through.

Thank you. My husband and I chose the tile (per recommendation at the tile store) and used a professional tiler (per recommendation at the tile store) for the install. It isn't a flip. This is a family home that we purchased and spent a year renovating—not DIY but with all professional hired help and a contractor to oversee the job. This tile person wasn't hired by him, though, as he was happy to use the person that we were told was very good by the tile store…. My heart is sinking. I absolutely hate the idea of retiling the shower as there is matching tile on all walls, including shower. I'm hoping there is some other idea out there that will help. I do personally think the tiler should have informed us if the tiles we supplied to him weren't suited to be mitered…we discussed it even before tiles were purchased and he didn't mention any specifications. I'm just worried now that if we put it on him to fix it, we'll end up with a bigger mess...
