Just to offer a different view point. Your floor tiles look amazing. Why not flow the idea through and use tiles of that ilk as your splashblack. We have just recently finished a kitchen with a similar feel and our client opted for patterned wall tiles as their splashback. Based on your comment about the floor being chosen to banish boredom If you are worried about carrying through more of the same tones and want to inject colour, you could always do this through your accessories, that way if you fancy a change.... The colour tones you have chosen provide a great canvas on which to complement or have fun with colour.

Wow that is a lot! The room is lovely btw. I'm struggling to find pics of upstands and the hob splashblack painted in the wall colour but this one will give you an idea. An alternative is to tile the splashblack as shown below, units and extractor are similar to yours so I thought it would give you a good visual although I'm not loving those particular tiles as much. If you go for a dark inky blue will you carry that through to the rest of the room at all? I still quite like the wood hex idea which will pick up your doors :)

Toughened vs non-toughened have been a dilemma for kitchen owners for a while. The objective truth is that yes toughened glass is stronger and heat resistant, but due to significant price difference sometimes it makes sense to take risk and just replace mirror in case of breakage, which will still be cheaper than buying full toughened from the beginning, especially taking in consideration that non-tgh antique is stock product and you don’t need to wait for 2-3 weeks for production. If you are looking for simple coloured or printed glass, then definitely go for toughened since price difference is insignificant and it’s not only safer and heat resistant, but also 4-5 times stronger to impact which is good against accidental hits. The other important fact is that broken mirror can bring you bad luck for 7 years!:) so only choose professionals for your installation. We are now producing probably over 100 splashbacks per month with fair share of toughned mirrors so happy to help!

I was hoping to get £150 which is just the proportionate material cost for that size piece. I had to pay expensive delivery and laser cutting fees on top but I'd have done that anyway so haven't included that in the price :) where are you located? We are in Manchester.
