Glass. I like white glass over any other colour. Will give good reflection still.
Stainless steel looks great in my opinion, and gives that professional edgy commercial look. Can also be very cheap if you know where to go. Also very easy to clean. I have used in in our house and in several renos.
Yay or Nay? Mirrored splashbacks
Which is the most timeless splashback material of all?
Help me pick splashback colour
What in particular concerns you about cleaning it, Jodie?
Hi Jodie, as someone already have mentioned above, you can choose from Stainless steel, Glass, Laminex "Metaline" (there is a reflective finish in this range)...Depending on the splashback size you have in your kitchen, these materials come in large-sized panels which means no joints and therefore an easy care...Hope this gives you some options to look at
