Hi Hannah! Wow I love the kitchen! I wish I had seen this earlier so I could suggest but I love the grey tile, it looks like a successful choice! You could add a marble cheese board to the island. The grey streaky tones In the board will probably tie in everything else. You could then put a terrarium on top of the marble board!

We did a heavy textured tile (each tile also has a different imprint design) in the same size but I went with white grout not to bring out the irregular grout lines too much. I feel it gives texture but not over the top! the pic u posted looks badly laid and they are different size tiles. There is great textured tile at Amber tile or colour tile (I'm in Sydney) otherwise I think like your husband suggests and go with the standard subway (but change grout to black for that industrial feel) otherwise how do you feel about a beveled subway? That would of been my next choice!

The photo is to feature bench top and table by Timber Revival. Maybe contact them (Website, Facebook or on Houzz) to find out about tiles in the picture? They may be able to tell you, or find out from one of their clients. They really are beautiful tiles.

I’m sure you can convert that space. Just need plumbing and electricity. You will have to get used to walking outside to laundry in all weather. personally I would of left the laundry as part of the bathroom. But I never use a bath.... The way I sort all my colours on the floor of the laundry, and sheets and towels, an outside set up would never work for me. But if it works for you, that is good.
