I would go for a lighter splash back, either stone or glass. There is a free app called 'paint tester' which you can upload your pics onto and try different colour combinations.

I'd go bright

I think keep the splash back light. Glass is a great option- easy to clean & guaranteed you will still love it in 30 years!

Otherwise you could go with the Subway tile trend which would make the kitchen look more homely.

Very cool kitchen! I love it. Have you considered smoked or bronzed mirror?

Looks good. You might want to consider sheet porcelain. There are medium sized sheets 3 mm thick but most large sheets say 3.2 x 1.5 m are 6 mm thick. No grout lines! May need CEC machining to handle those power socket cut-outs.

...CNC machining.

I see that you have Stainless steel appliances so you might want to think about Champagne Glitz it matches in with the appliances also grubby finger marks do not show up as much.

I went with a mirrored splash back in my kitchen. Makes the room feel larger, easy to clean and reflects light making the room brighter.

This is what I have wanted on my splashback....just can't quite afford it at the moment. :)
This is a NZ photographer and although her images are mostly of NZ, however, if you live elsewhere, you are able to use your own, or buy the copyright to use hers and get the splashback made in your country.
They add colour, drama and are a conversation piece.

I would add some sparkle and shine with cut mirror and glass tiles - they are small tiles and come on a sheet. I have seen them on TV and they look fantastic.

Hey ka5en , just love those LucyDesign splashbacks! Having grown up in NZ, I'd love to have the view of Rangitoto from Kohi. Brings back memories of a childhood spent on those beaches :)

Hex tiles are trending now!

For something bright and colourful a blue accent would look stunning. Otherwise stick to neutral, warm tones such as cream or beige, perhaps in a hexagonal tiles as Monika suggested above or a warm marble.

Have you considered an aluminium splashback? Easier to clean than tiles and glass, and you can get any design including the look of tiles, an artwork or favourite photo. Here are some of our suggestions!

@Decorative Imaging
Never heard of these ^^. How much compared to the glass ones?
I would be interested for myself considering you can supply your own images.

Hi @ka5en. The price of glass can vary wildly, but aluminium splashbacks are usually around 20-25% cheaper than compliant single colour glass, and about half the price of customised glass splashbacks. Hope that helps.

@ Decorative Imaging. Thanks. Anything that does an equally good job and is cheaper is a viable option IMO. :)

Have a look at my splash back site: vandertouwdesign.co.nz Plenty ideas and also most splash backs are one off designs.
