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.

They do look a lot like the marble tiles but these would certainly be pretty. I see that you can have a sample sent to you for a small cost .join www,myus.com which gives you a post box US address if needed to do this. You will certainly need to grout them using a water mould proof grout. If you found them to be a problem just have them covered with clear glass,

Your kitchen is small and already quite busy. I would make it as simple and clean as possible. You can't beat ceramic tiles for cost, durability and ease of installation. Have a look at Johnson's Spectrum range to see if you can match the green. https://www.johnsontiles.com.au/product/spectrum/?utm_campaign=1602072422&utm_source=google&utm_medium=cpc&utm_content=304640004469&utm_term=&adgroupid=61761480198&gclid=CjwKCAjw_YPnBRBREiwAIP6TJ0idAicM8vfEevC-WrwRVNmbtUPHfDAjvNpkaOIo0hzN0dwMw9u1rxoC0VkQAvD_BwE You will get a neater finish with ceramic tiles than you will with trying to work with DIY stainless steel, particularly around the edges. There are lots of online resources to show how easy it is to lay smaller ceramic tiles. Leave the large format porcelain tiles to the professionals. Best of luck, Dr Retro of Dr Retro House Calls

Hello, thank you for your response. For some reason the site defaulted to the Australian discussion forum when I posted but I just went with it anyways and didn't think much of it. I understand your point about different perspectives in different countries though, thanks. I know this is all based on personal preference but I like either option of so I am looking for some other opinions. The developer has been very helpful with the different options and we plan to speak to some other local professionals as well. We have seen the materials in person (except for cabinets) in very small sample sizes and all of the colours seem to compliment eachother but for the purpose of this post a digital photo was the only option of course.
