There are a huge range of options and it would depend on the look and feel of what you want to achieve, your personal view on colour & boldness, what else is close by (to tie in with) and budget. A coloured glass, such as a citrine green or orange would look great. A very different style/look, but equally eye-catching would be some interesting patterned tiles such as the Patricia Urquiola collection from Surface Tiles in London (and elsewhere). My personal preference would be to opt for a white/grey marble such as a Calacatta D'oro which would be incredibly luxurious and bring in the white and soft greys as well as adding a hint of warm caramel. That is if budget allowed. Carrera marble is less costly but has a greyer background. It is always advisable to go and choose a slab of marble from the stone yard.

Is there any reason why you're not having the same quartz for the up stand as you are having on the worktop? That would be most people's choice. I do like the tiles however, and think they would go very nicely with what you describe.

Hi Tashmina, I like the tile, however I would like to see how you intend to incorporate this with your kitchen? What colour is it? Is it a modern or more traditional kitchen?

Are you saying the glass splashback is the wrong size because it doesn’t go all the way up to the extractor fan? If so I’d guess that they’ve installed a standard size as opposed to a purpose made size. If so l would just take that one down and get a taller one made. You could always have the splashback all the way across the wall. l don’t think it needs tiles too. You could add a tint of colour with the emulsion,
