I used to think bathroom tile size was only about appearance, but it actually changes how the bathroom feels and works daily.
Large tiles usually make bathrooms look cleaner and more modern. Because there are fewer grout lines, the floor looks less busy and more open. I also think large tiles can make small bathrooms feel slightly bigger visually.
Another thing people like is that fewer grout lines means less cleaning over time.
But large tiles are not perfect for every bathroom. In smaller spaces with many corners or floor slopes, installation can become harder. Water drainage also needs to be done properly so water does not sit on the floor.
Small tiles give more grip because there are more grout lines between them. That is one reason many people still use smaller tiles in bathrooms and shower areas.
Small tiles can also fit uneven bathroom floors more easily during installation.
So, large tiles are better for a cleaner modern look, while small tiles are more practical for grip and detailed bathroom layouts.
Both can work well depending on the bathroom design and daily use.
