Generally it has to be Quartz, though we do love others, as sometimes they can give the right feel for the design you want. Different metals can look amazing and Quartz can't replicate these. We are just starting a project that has mainly Quartz but one side of the island will be copper . . . Can't wait to see the finished look

Love your kitchen, you’ve done a great job, not only does the kitchen look good, it’s totally practical, drawers are the way forward, even if they are more expensive than cupboards. I’ve just redone a kitchen in a house we rent out, the old one was finally falling apart. I was going to go to Howdens and use the joiner etc we knew, but in the end we used a small local company, which cost us £300 more, but the quality of their interior cabinets and doors was so outstanding, plus they could do everything, including tiling, we went with them. We didn’t change the floor, but did everything necessary, I’m hoping it lasts well and our tenants look after it!

We supply all sorts of kitchen worktops but I’d never heard of them. Had to Google it. Wouldn’t like to be measuring my own worktops TBH just in case there’s a slight error. Don’t they send a person out to electronically measure them?

You could consider an insurance claim. Ideally to fit the new worktop the splashbacks need to be removed, this will probably damage the walls so its quite a big job. You may find a fitter who is prepared to work with the splashbacks in place, but the sink run would have to be cut short to fit in between the splashbacks and then the gap filled with silicon. How to get the worktop in position may also mean removing some wall units as well. then for the 2 side worktops being able to slide under the splashback and making a decent job of the masons mitre, keeping an even overhang to the doors etc, not a job i would of undertaken when i was fitting. You mention water resistant laminate, if you mean compact laminate, the max thickness is 20mm so there'll be a gap. If you mean laminate but made with 'green' chipboard, it still needs sealing and if its constantly subjected to moisture it will still blow. I'd suggest a new worktop in a stone/abstact pattern colour as you have a modern door style, make sure it's a bullnose and not these edged worktops [i've seen these fail around sink area], get rid of the splashbacks and fit some metro tiles in a brick pattern, also get rid of the windowsill so that is also tiled instead of that gap you have under the sill. Reason for tiling is that if the splashbacks have been stuck on with silicon, even if the wall isn't damaged any silicon may affect the new paint. For the sink, you mention that you want to wash oven trays, so for a bigger bowl opt for a single bowl with a right hand draining board as well, looks like its a 600 sink base in the pics so there's plenty of choice, personnally i'd have a 1.5 bowl though as Betty says, also opt for a composite/granite [as below] so you can just drop the sink in place on a bed of silicon beading, stainless steel would ideally need the clips underneath [there are a few push in stainless sinks though with spring clips].
