what about flush stainless steel caps the same size as the posts you took out. Similar to the feature tile idea, and there may be a ready made solution available from a pool fencing supplier.

There used to be a discontinued tile store in Sydney.

I think the interior design team is the same one who did their Sydney restaurant - they are not on Houzz but their name is Meacham Nockles McQualter. Might be worth a quick email to them to see where they sourced from.

Hi Ellie These are beautiful tile choices and I have used these in my projects too. The decision to stack or brick pattern is a personal preference. Perhaps the style you are trying to achieve in the rest of your home could be your guide. I agree with above comments that stacked is more modern, brick a bit more rustic especially with these tiles as they have a handmade look with a wavey edge. I would definitely do both the kitchen and the pantry the same pattern or it could look like it wasnt a considered decision. Best wishes.
