How funny. I just renovated (on a budget) my small kitchen and added exactly the slate look in tiles you have, though they are in fact porcelain. And I placed them throughout the house for continuity. The tiler asked if I was after a retro hippy look but it doesn't look like that at all. My cupboards were the same colour as yours and I utilised the bones of the kitchen and had the doors and Benchtops changed only. I also have plenty of light in the kitchen but chose white doors and as I was on a budget I chose granite look Benchtops, they are very serviceable and it looks great. The blue backsplash was the colour lift and here you could choose any colour to your liking. Basically the kitchen ended up with white cupboards and appliances other than cooktop, with the stainless cooktop and coloured splash back being the focal point. The paint colour are: whisper white walls, integra splashback, white ceiling and for increased contrast I used the same white above the splashback on the rear wall. I would consider painting out the brick but leaving the texture.

Have you been to visit some kitchen showrooms? You can customise the photo search here on Houzz quite a bit. For example, you can simply select [dark wood[(https://www.houzz.com.au/photos/kitchen-design-ideas-with-dark-wood-cabinets-phbr1-bp~t_10444~a_17-103) cabinet finish in the filter options. Then add more filters like floor colour, kitchen layout, cabinet style, wall colour etc if you wish. Leave the benchtop and splashback options open and see what results you get. You can then save any photos that appeal to your ideabook.

Have you priced having the whole lot re waterproofed and tiled? You are already doing the hardest section, it may not be that much more to do the lot. Otherwise agree with above match to the white tiles in the rest of the bathroom. But it will always look like a repair.

I have got the sample pots and I’ve painted them on large cardboard, it’s more the benchtop I want to blend in nicely, as well as splashback. I know I won’t find the exact combinations, would be nice to see one or two of the colours to get a more visual idea. They aren’t the popular ones like lexicon and all the mainstream dulux whites. So the bricks have all been removed, and under the bench is just going to be the same as the kitchen cupboards. The brick pier has been Gyprocked. Do you think a smoky mirror splashback will look good?
