Awesome!! Actually macymacmaples, the mirror will date more than the white glass. My cupboards will be white handleless polyurethane...and I'm gonna choose Ceasartsone Calacatta Nuvo as my benchtops :) hagan - My painter (which is my cousin) lol, also wants me to do vivid white ceilings..but I'm thinking of just keeping it the same and doing Natural white ceilings too as I don't like contrast...I prefer it to all blend....Dunno yet tho, will keep u updated ;)

I think a dark grey grout would look great, the wider the gap the more the tiles stand out, if it wouldn't cost too much and you had some spare tiles you could do a mock up on a piece of board , sometimes the only way to really gauge things is to actually see it

Do you have any other colours in your colour scheme in the rest of your house that you might like to incorporate? I think your current colour scheme in the kitchen lends itself to quite a few different options .... black & white encaustic tiles, smoky glass mirror splashback, a coloured sheet of acrylic or check out the range of tiles from Southern Cross Ceramics.... they make it hard to choose! So many beautiful options, colours & patterns .... they have a visualizer too so you can see how it all looks :)

Sorry didn't finish my post, but I think the marble would work the best
