There's just me living in this space. In the 4mths I've lived here so far I haven't had to clean the tiles on back wall but it is dark so maybe I can't see the mess. As for the sink area there's water splashes always on the tiles. The kitchen designer advised me against using the mirror here for that reason.

Clear island bench. For prep,serving,eating, etc. ONLY Keep the messy dishes away for both cooking and cleaning

I would get an upholsterer to do a couple of long foam cushions for the seats - colour would very much depend on the rest of your home, but teal would look good there (and so would navy).

I totally agree with the advice above. Just a tip with the accessories - you might be very tempted to get all black & white, or super graphic prints. But, because the brown caesarstone will need balance in the room I'd suggest bringing in neutral earthy greyish colours, a bit of navy, and even a bit of gold. Unless you swap the brown benchtop for something crisp & white or black, or a single colour... then you will have a fantastic & strong themed 'retro look', and your red barstools will work. Some nice accessories to break up the red & suit the benchtop could be these kinda colours:
