Looks great from what is shown, but could you post a photo showing the whole kitchen please? I am having the same dilemma and very keen to see more of your tiles.

Try a slim porcelain sheet in a concrete look finish. The large format size means you'll probably need only one, so there'll be no grout lines. Have a look here, at the Portland 3.0. I think the Kerlite range also does a concrete look and is larger, at 3m long. The other advantage of a porcelain tile over actual concrete, is that you just wipe it down. Concrete is porous and will stain.

The tiles from Johnson in the UK are stunning. It appears they only come in large 30x30 ? I was thinking of doing some sort of tile art just in the middle of the backsplash with the rest just plain offwhite tile. However, with this large 30x30 art work, the background tile would have to be cut to size to fit the area I have and might look too choppy???

Hi Mc10. I bought the Calcatta subway tiles on a mesh and will use this Lithofin MN Stain-Stop Tile Sealer once every 3 years. I’m still in the middle of the kitchen reno but got my marbles and they’re exquisite. https://marbleceramiccorp.com.au/lithofin-sealant-germany/1026-lithofin-mn-stain-stop.html?gclid=Cj0KCQjwr-SSBhC9ARIsANhzu16AK7RpYQb4yMtmHougfhBuuiyMAu930aAIj-0gu55tx1mM4dc-IOkaAr-ZEALw_wcB
