Welcome to the Bunnings Workshop community @venterkasi. It's brilliant to have you join us and many thanks for your question on repairing a tile.
You can repair the broken section of tile with a white epoxy filler. Start by giving the area a really good clean so the filler bonds properly, and tape up the surrounding tiles to avoid smears. When applying, don’t overfill. It’s easier to add a little more later than to remove too much. Once the filler has fully cured, carefully sand it back so it sits flush with the surrounding surface.
A bit of patience here will give you a neat, long-lasting finish.
Please let me know if you have any questions.
