Glass would look good - give you a little reflectance without mirroring everything on the worktop. Also could be a subtle way to introduce some colour. If you use clear glass with screw back type fixings, then you can change the colour now and then by painting the wall behind if you're nervous about colour, or think you would want to change the look now and then. Another option is a stainless steel, which again would add in a little light reflecting but in a grey tone that would work well with what you have.

For me the most important thing was how it would "go" with the rest of the kitchen. Also, as I planned the kitchen, I needed to understand how and how well, the splash back would intersect with the extractor, the wall units and the worktop upstand. FWIW I would never have had a printed glass splash back, although we did consider a plain white one. But the style of the extractor meant the splash back needed to be shaped around the extractor unit - not so easy with pre-made glass splash back. My biggest turn off with websites is bad grammar and spelling mistakes. I feel that if a company cannot be bothered to check something as important (and often the first interaction the company has with potential customers) then I would question how careless they would be with my order. I also hate pop ups and distraction on a page. For instance - and I hope you don't mind me commenting on your website - having the phrase "package deals available!" at the top of most product pages is a distraction for someone just looking for a splash back. It looks like it's a trade only thing and it looks a bit down market and a bit Trotters Independent Traders'ish. Perhaps combo offers may be better mentioned on a separate page of "offers" or a small section in the product information that combination/bundle deals of a splash back and worktop are available.

Thanks Sonia, it’s beautiful isn’t it. Juliet recommended the Raku range, they are gorgeous. Any suggestions on tile pattern?

Mirror splashbacks can make a small space look really cool between wall units and base units. Apart from the standard mirror silver you can get antiqued (is your kitchen style dictates this) or coloured glass such as copper/bronze. If you are not that keen at looking at yourself then a smoked grey is a great option for modern contemporary kitchens. Mirror splashbacks can be cut around sockets for that perfect look. Ensure behind your hob that you have toughend glass otherwise it could shatter with the heat from the hob. A simple upstand in the same material as your worktop say 75mm high is simple then use a washable paint for above for a simple look. Hope that helps
