I have thought about some sort of white cabinetry too but could it look a little odd with the rest of the house, as the house is rustic? My second thought was maybe oak cabinets with a light granite bench top, which would be the safer but maybe not so modern? I really don't like the look of painted bricks. I have seen some very nice brick wall kitchens on Houzz but my kitchen seems to have more bricks then most and a lot of the kitchens in Houzz mix plaster in the room, which looks amazing but I can't do that. I have found a great fabricator for the granite. I have also found that granite isn't much more expensive then Engineered Stone so I would rather go for the real thing.

What a beautiful tile! Rule of the tump - always match the grout to the tile. Specially with such a strong patterned tile, otherwise the grout also becomes a clashing pattern. I'd pick light grey to avoid pure white cleaning issues. I have these type of tiles in my patio, you will have to be seal them with penetrating sealer after installation, but other then that you will love them forever

I think if your surroundings are white and black with hardwoord timber floor, go with charcoal colour. Blue colour reminds me of when we used to go to the Snooker rooms in the city they were all blue. Charcoal is different and very modern.

Hi there we went with a glass splashback in Haynes Minimalist #1. I can DM photo if you like? Learning for me is that the colour sample tile does not take into account a finished room, flooring, lighting, natural light etc. as glass is so reflective. I found it very difficult to find a glass colour that suited both the stone and cabinet. Cheers
