We're with Valduff. Shades of purple and plum can really add depth to a chic scheme like yours. Particularly with your gorgeous counter top. Grey is also a good call, as it will coordinate with your kitchen units but allow room to add coloured accessories. It can depend on the light quality in your room- we always recommend grabbing some tester opts in a range of shades. Paint your walls or A4 sheets, and see what the colours look like as the light changes throughout the day.

I feel your pain as I did the same with my stainless steel oven. I rubbed some oil gently on it and it did help, but the t cut idea sounds good!

Do you like patterned tiles at all? Doesn’t have to be garish and you can keep the pallet simple. I’m thinking tile the whole wall, the same width as the vanity unit, up to the ceiling, similar to first picture. Or if that’s too much, then just tile the space from the sink to the mirror. I would raise the mirror a little so that it doesn’t get too splashed.

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,
