How to cover big gap between floor tiles?

Jodd

I took off a safety screen door and left a big gap between the floor tiles, not planning to change new tiles.  

What is a better option to fill the gap? Grout? Silicone? Or do I have other options that is long lasting but can match colour of tiles too.

Welcome to the Bunnings Workshop community @Jodd. It's brilliant to have you join us, and many thanks for your question about filling a gap in tiles.

The best long-term solution would be to try sourcing tiles similar to your existing ones and replacing the ones with cut sections in them, but that can be difficult if the tiles are older. If matching tiles aren’t available, you could grout the gap in a similar colour, though the texture would likely stand out. Silicone would give a smoother, more flexible finish that’s easier to keep neat, but finding an exact colour match can be tricky, and it may discolour over time. Another option is to install an aluminium or PVC floor trim or threshold strip to cover the gap entirely, which can create a clean, intentional look without trying to blend different materials.

Let me mention @Dave-1 to see if he has any thoughts.

Please let me know if you have any questions.
