If it is done in a different pattern, I think you should be fine.

Sunny - I would keep the kitchen tile for the kitchen and use something different in the bathroom. One of my concerns for our new kitchen - I don't want it to look like a bathroom - and if you have the same tile in both....
Good luck!

I don't like using the same tile in both spaces, but that's just me. In my honest opinion I sometimes think that it looks like you just wanted somewhere to use your left over tile. There is so much beautiful tile out there I would want to do something different, but again that's just me.

Thanks for your advice. I am going to look for something different. I was thinking it would be too much in both.
